ANTIINFECTIVES

*Fight infection-Bacteriostatic: retard (limit, slow) growth of microorganism-Bacteriocidal: kill microorganisms

*Bacteria, viruses, fungi, protozoa*Spectrum: the number of organism that medication is effective against

-Broad Spectrum: will kill everything-Narrow Spectrum: is used for specific infections, effective

against only a few organisms*Bacterial Resistance: after multiple exposure to a medication, the bacteria will mutate and become infective against the drug. For example: MRSA, VRE

*Super-infections: when other organisms that are not sensitive to prescribed antibiotic (for example, yeast) are able to multiply, overgrow and get out of control because the antibiotic also killed the organisms that would have kept them under control

*Culture & Sensitivity: diagnostic test to find out the specific bacteria and what drug will be effective against it

Page 88: Pharmacology- Drug Cards (Index Cards)

A child born to a mother taking benzos may experience withdrawal symptoms during the postnatal period.

Gerontology: the older adult is at greatest risk for oversedation, dizziness, confusion or ataxia (unsteady gait) when taking a sedative or hypnotic. The nurse checks elderly and debilitated patients for a paradoxical reaction, such as marked excitement or confusion. If excitement or confusion occurs, the nurse observes the patient at frequent intervals (as often as every 5-10 minutes may be necessary) for the duration of the occurrence and institutes safety measures to prevent injury. If over sedation, extreme dizziness or ataxia occurs, the nurse notified the primary health care provider

o Barbiturates: have little to no analgesic action, so the nurse does not give these drugs if the patient has pain and cannot sleep. Barbiturates when given in the presence of pain, may cause restlessness, excitement and delirium.

o HOLD medication if respiration rate is 10 breaths/min or below or if patient is lethargic Sedative: a drug that produces a relaxing, calming effect. Sedatives are usually given during daytime hours,

and although they may make the patient drowsy, they usually do NOT produce sleep Hypnotic: a drug for short-term use to promote sleep. It induces drowsiness or sleep, it allows the patient

to fall asleep and stay sleep. Hypnotics are given at night or bedtime Gerontology: elderly patients may require smaller hypnotic dose and in some

instances, a sedative dose produced sleep.

o Depression: A major depressive episode or a depressed or dysphoric (extreme or exaggerated sadness, anxiety or unhappiness) mood that interferes with daily function. For a classification of clinical depression, five or more of the symptoms need to occur daily or nearly every day for a period of 2 weeks or more. The symptoms of clinical depression are not the result of normal bereavement, such as a loss of a loved one or another disease.

-Hopeless -Significant weight loss/gain -Insomnia or hypersomnia-Decrease in interested/engagement -Fatigue or loss of energy-Agitation/restlessness/irritability -Feelings of worthlessness-Excessive/inappropriate guilt -Changes in concentration-Recurrent thoughts of death/suicide (or suicide attempt)

CONTRAINICATIONS*Patients with hypersensitivity to drugs similar chemical class, use of MAO inhibitors within 14 days, patients with recent MI, to children or lactating mothers. *Doxepin is contraindicated in patients with glaucoma or in those with a tendency for urinary retention*TCAs should be used cautiously in patients with cardiac disease, hepatic or renal impairment, hyperthyroid disease, history of seizure activity, narrow-angle glaucoma or increased intraocular pressure, urinary retention and risk of suicidal ideation behavior INTERACTIONS

Drug:Adrengeric agents increased risk for arrhythmias and hypertensionSedatives/hypnotics/analgesics increased risk for respiratory & nervous system depressionMAO inhibitors increased risk for hypertensive episodes, severe convulsions & hyperpyretic episodesNURING PRECAUTIONS*Although the TCAs are not considered antipsychotic agents, the drug amoxapine has been associated with tardive dyskinesia and neuroleptic malignant syndrome (NMS). Tardive dyskinesia is a syndrome of involuntary movements that may be irreversible. Symptoms of NMS are similar and include muscle rigidity, altered mental status and autonomic system problems (such as tachycardia or sweating). These syndromes tend to occur more readily in elderly women; the drug should be discontinued, the primary health care provider notified immediately & treatment of adverse effects begun quickly.*TCAs can cause cardiac-related adverse reactions, such as tachycardia and heart block. The nurse therefore gives these drugs with caution to the person with preexisting cardiac disease, and to the elderly.

ADRENERGIC DRUGSPeripheral Nervous System

Autonomic Nervous SystemSympathetic v. Parasympathetic nervous system branches

Sympathetic (Adrenergic) = regulated by involuntary control. In other words, a person does NOT have control over what this system does. Fight-or-Flight response is activated when the body is confronted with stressful situations, such as danger, intense emotion or severe illness. Controls person’s heart rate, breathing rate and ability to divert blood to skeletal muscles. This branch of system is based on the neuro-hormone adrenalin (epinephrine) and norepinephrine (neurotransmitter). Examples: Dobutamine, epinephrine (EpiPen), Midodrine (ProAmatine)

In the sympathetic branch of ANS, adrenergic drugs produce activity similar to the neurotransmitter norepinephrine. Another name for these drugs is sympathomimetic (for example: mimicking the actions of the sympathetic nervous system) drugs.

The adrenergic drugs produce pharmacologic effects similar to the effects that occur in the body when the sympathetic nervous (norepinephrine) and the medulla (epinephrine) are stimulated. The primary effects of these drugs occur on the heart, the blood vessels and the smooth muscles, such as the bronchi of the lungs.

ADRENERGIC BLOCKING DRUGS

Peripheral Nervous SystemAutonomic Nervous System

Sympathetic v. Parasympathetic nervous system brancheso Sympathetic Nervous System (Adrenergic Branch, “Fight or Flight”): tends to

regulate the expenditure of energy and is operative when the organism is confronted with stressful situations. Anti-adrenergic or Adrenergic Blocking medications block or inhibit the system and sympathetic nervous system. One of the major body systems impacted by adrenergic blocking drugs is the heart and vascular system. Some of the drugs are also used to treat hypertension.

Alpha-adrenergic blocking drugs: produce their greatest effect on the alpha-receptors of the adrenergic nerves that control the vascular system, causing vasodilation and relaxing the smooth muscle of blood vessels (also used to constrict pupil).

Example: Phentolamin (Regitine) Beta-adrenergic blocking drugs (Beta Blockers): blocks β-adrenergic receptors and their effect

on β receptors, primarily the β receptors of the heart, decreasing heart rate and dilates the blood vessels.

Examples: Atenolol, Metoprolol (Lopressor, Toprol XL), Propranolol α- β adrenergic blocking drugs: blocks both α AND β adrenergic receptors and effects the

nerve fibersExample: Carvedilol (Coreg)

Anti-adrenergic drugs: prevents the release of neurotransmitter norepinephrine and blocks the adrenergic nerve impulse in both central & peripheral nervous systems

Example: Clonidine (Catapres)

CHOLINERGIC (PARASYMPATHOMIMETIC) MEDICATIONS

Acetylcholine (ACh) is the substance that transmits nerve impulses across the parasympathetic branch of the Autonomic Nervous System.

o Autonomic Nervous System: is concerned with functions essential to the survival of the organism. Functional activity of the autonomic nervous system is not controlled consciously (the activity is automatic). This system controls blood pressure, heart rate, gastrointestinal activity and glandular secretions.

Parasympathetic Nervous System (Cholinergic Branch, “Rest & Digest”): help conserve body energy and is partly responsible for such activities as slowing the heart rate, digested food and eliminating bodily wastes. Cholinergic drugs that enhance neurotransmission and anti-cholinergic drugs block transmission.

Muscarinic Receptors stimulates smooth muscle Nicotinic Receptors stimulates skeletal muscle

o Direct Acting Cholinergics: cholinergic drugs that act like the neurotransmitter ACh and acts on the ANS that controls the process of micturition (voiding of urine) by constricting the muscle and relaxing the bladder sphincter.

o Indirect Acting (Anticholinesterase) Muscle Stimulants: these medications are used to treat myasthenia gravis (disease that rapidly fatigues skeletal muscles because of the lack of ACh released) and promote muscle contraction.

o Topical Ophthalmics: as indirect-acting cholinergic drugs that produce miosis (constriction of the iris) that are used in the treatment of glaucoma. This opens the blocked channel and allows the normal passage of aqueous humor, thereby reducing intraocular pressure.

ANTICONVULSANTS

A seizure is defined as periodic disturbances of the brain’s electrical activity Convulsion and seizure are interchangeable

Page 140: Pharmacology- Drug Cards (Index Cards)

Seizure Disorders are categorized as idiopathic, hereditary or acquired. Seizures caused by disease, such as epilepsy, may be a permanent, recurrent seizure disorder. Examples of the known causes of epilepsy include brain injury at birth, head injuries, inborn errors of metabolism and sometimes are never determined. Each seizure disorder is characterized by a specific pattern of events, as well as a different pattern of motor or sensory manifestations.

Partial seizures: most common type of epileptic seizure, localized in the brain; motor seizures with uncontrolled stiffening or jerking in one part of the body such as the finger, mouth, hand or foot that may progress to the entire limb. They may present as flashing lights or a change in taste or speech (somatosensory seizure).

Generalized seizures: involve a loss of consciousness and may or may not include convulsive movements. Manifestations of a generalized tonic-clonic seizure include alternate contraction and relaxation of muscles, a loss of consciousness and abnormal behavior. Myoclonic seizures involve sudden, forceful contractions of single of multiple groups of muscles.

Anticonvulsants are used in the management of seizure disorders. Examples: Phenytoin (Dilantin), Phenobarbital (Luminal), Diazepam (Valium), Lorazepam (Ativan)

SKELETAL MUSCLE RELAXANTS

Page 145: Pharmacology- Drug Cards (Index Cards)

A variety of drugs are used in treating musculoskeletal (bone and muscle) injuries and disorders. Skeletal muscle relaxants are used to assist in the relaxing certain muscle groups, as strain and sprains are repaired.

o Many of these drugs do not directly relax skeletal muscles, but their ability to relieve acute painful musculoskeletal conditions may be due to their sedative actions

Cyclobenzaprine (Flexeril) appears to have an effect on muscle tone, thereby reducing muscle spasm

ANTI-RHEUMATIC & URIC ACID INHIBITORS

Page 150: Pharmacology- Drug Cards (Index Cards)

Anti-Rheumatic Drugs Rheumatoid Arthritis is a chronic disorder (an autoimmune disease) involving the

inflammation and accumulation of fluid in jointso This condition is typically treated using three classification of drugs

(1) NSAIDs, (2) corticosteroids and (3) DMARDs Disease-Modifying Antirheymatic Drugs: have properties to produce

immunosuppression, which in turn decreases the body’s autoimmune response. Example: Methotrexate (MTX) (Rheumatrex)

DMARDs may also be used for other purpose, such as cancer therapy

Uric Acid Inhibitors (Gout) Drugs Gout is a condition in which uric acid accumulates in increased amounts in the blood and

often is deposited in the joints. The deposit or collection or urate crystals in the joints causes the symptoms (pain, redness, swelling, joint deformity) of gout.

o These medications reduce the production of uric acid, thereby decreasing serum uric acid levels and the deposit of urate crystals in joints. This probably accounts for its ability to relieve the severe pain of acute gout.

Example: Allopurinol (Zyloprim) and Colchicine

Methotrexate (MTX)(Rheumatrex)

Page 151: Pharmacology- Drug Cards (Index Cards)

ACTION Anti-Rheumatic medication Disease-Modifying Anti-Rheumatic medication

INTERACTIONSDrug:Sulfa Antibiotics increased risk of methotrexate toxicity

Aspirin and NSAIDs increased risk of methotrexate toxicity

NURSING PRECAUTIONS*Because DMARDs are designed to produce immunosuppression, patients need to be monitored routinely for infections. Instruct patients to report any problems, no matter how minor, such as a cold or open sore—even these can become life threatening.*When taking methotrexate, use a calendar or some memory device to remember to take the drug on the same day each week.*Call MD immediately if you have: sore mouth or sores in the mouth, N/V/D, fever, sore throat, easy bruising, rash or itching

ANTIHISTAMINES & DECONGESTANTS

Page 153: Pharmacology- Drug Cards (Index Cards)

Antihistamines: histamines are produced in response to an allergic reactions or tissue injury. It acts on areas such as the vascular systemand smooth muscle, producing dilating of arterioles and an increased permeability of capillaries and venules.

Antihistamines are used to block the cell receptors, this counteracting the effects of histamine on body organs and structures.

Examples: diphenhydramine (Benadryl), loratatine (Claritin), fexofendaine (Allegra) and cetirizine (Zyrtec)

Decongestants: are drugs that reduces swelling of the nasal passages, which in turn, opens clogged nasal passages and enhances drainage of the sinuses. These drugs are used for the temporary relief of nasal congestion caused by the common cold, hay fever, sinusitis and other respiratory allergies.

Examples: pseudoephedrine (Sudafed)

BRONCHODILATORS Bronchodilators: (two types of bronchodilators) When bronchospasm occurs,

there is a decrease in the lumen of the bronchi, which decreases the amount of air taken into the lungs with each breath. A decrease in the amount of air taken into the lungs results in respiratory distress. Use of a bronchodilating drug opens the bronchi by relaxing the smooth muscle and allows more air to enter the lungs, which, in turn completely or partially relieves respiratory distress.

o β2 Adrenergic agonists (sympathomimetics: When the sympathetic system in the lungs are stimulated, bronchoconstriction results. During bronchodilation, β-adrenergic receptors are stimulated.

Short-acting: Albuterol (Proventil, Ventolin) and Terbutaline (Brethine)

Long-acting: Salmeterol (Serevent Diskus)o Xanthine Derivative Bronchodilator: (also called methylxanthines).

They stimulate the central nervous system to promote bronchodilation. The cause direct relaxation of the smooth muscles of the bronchi.

ANTIASTHMAS Inhaled Corticosteroids: ICSs are the most consistently effective long-term

control medication at all steps of care for persistent asthma. ICS and LABA drugs may be combined to ease administration of the medications and produce positive outcomes in management of asthma.

Example: Fluticasone (Flovent, Flonase) ICS/LABA Combination: Anti-inflammatory medication that reduce airway hyper-

responsiveness, reduce the number of mast cells in the airways and block reaction to allergens.

Examples: Budesonide/formoterol (Symbicort), Fluticasone/Salmeterol (Advair)

Leukotriene Receptor Antagonists: Asthma attacks are often triggered by allergens or exercise. Inflammatory substance called leukotrienes are one of the several substances that are released by mast cells during an asthma attack. These medications are considered leukotriene receptor antagonists because they inhibit leukotriene receptor sites in the respiratory tract, preventing airway edema and facilitating bronchodilation.

Example: Montelukast (Singulair)

ANTIHYPERTENSIVE MEDICATIONS Hypertension is a disorder in which that patient’s blood pressure is elevated above normal values for their age. Research has

shown that blood pressure above 140/90mmHg are associated with accelerated vascular damage of the heart, brain and kidneys. There are (5) types of antihypertensive medication:

1. Diuretics: indirectly reduce blood pressure by producing sodium and water loss and lowering the tone or rigidity of the arteries.

-Loop Diuretics: Fuosemide (Lasix)-Thiazide & Sulfonamide Diuretics: Hydrochlorothiazide (HCTZ)-Potassium-Sparing: Spironolacton (Aldactone)

2. Adrenergic Antagonists: are nervous system stimulants and inhibitors that assist in lowering cardiac output and/or peripheral resistance

Examples: Clonidine (Catapres, Duraclon), Metoprolol (Lopressor Topol XL)

3. ACE Inhibitors: affect the renin-angiotensin system of the kidneys. Angiotension-converting enzyme (ACE) inhibitors act on the rennin-angiotension system to promote a decrease in the work of the heart (vascular afterload and preload) through vasodilation (vascular opening) when angiotension II is inhibited. Angiotensin II is a powerful vasoconstrictor that acts on the adrenal cortex to increase aldosterone secretion. If a patient is in shock, this renin-angiotensin reaction is important in saving sodium and water to keep the blood pressure up but at other times, it may help lead to the high blood pressure found in hypertension.

Examples: Benazepril (Lotensin), Lisinopril (Zestril))

4. Vasodilators: Vasodilators reduce systolic and diastolic blood pressure by direct relaxation of vascular smooth muscle, thus lowering peripheral resistance.

Examples: Hydralazine (Apresoline), Minozidil (Loniten)

Page 178: Pharmacology- Drug Cards (Index Cards)

5. Calcium Channel Blocking Agents: selectively limit the passage of extracellular calcium ions through specific ion channels of the cell membrane in cardiac, vascular and smooth muscle cells. This causes a lowered peripheral vascular resistance and a fall in systolic and diastolic blood pressure.

Examples: Amlodipine (Norvasc), Diltiazem (Cardizem), Nifedipine (Procardia) and Verapamil (Calan)

Furosemide(Lasix)

ACTION Antihypertensive Loop Diuretics

USES Edema due to heart failure, cirrhosis of the liver, renal

disease, acute pulmonary edema and hypertension

ADVERSE REACTIONS*Electrolyte and hematologic imbalances, anorexia, N/V, dizziness, rash, photosensitivity, orthostatic hypotension

NURSING PRECAUTIONS* Obtain patient’s weight before and periodically during furosemide therapy to monitor fluid loss.* Monitor blood pressure and hepatic and renal function as well as BUN, blood glucose, and serum creatinine, electrolyte, and uric acid levels, as appropriate* Be aware that elderly patients are more susceptible to hypotensive and electrolyte-altering effects and thus are at greater risk for shock and thromboembolism* If patient is at high risk for hypokalemia, give potassium supplements along with furosemide, as prescribed* Call MD if patient experiences hearing loss, vertigo, or ringing, buzzing, or sense of fullness in her ears. Drug may need to be discontinued* Instruct patient to take the last dose of furosemide several hours before bedtime to avoid sleep interruption from diuresis. If patient

Page 179: Pharmacology- Drug Cards (Index Cards)

receives once-daily dosing, advise her to take the dose in the morning to avoid sleep disturbance caused by nocturia* Advise patient to change position slowly to minimize effects of orthostatic hypotension and to take furosemide with food or milk to reduce GI distress

ANTIANGINAL MEDICATION Angina is pain caused by narrowing or constriction of the smooth muscle in the coronary

arteries and the peripheral vascular system that reduces the amount of blood carried to the heart. When there is a lack of blood supply to being oxygen and nutrients to the heart or to peripheral tissues, the pain of angina or peripheral vascular disease is felt.

Nitrates are the best dry for treating coronary artery disease, whereas vasodilating agents are used for peripheral vascular disease. The use of beta blockers and calcium channel blockers may also play a role in treating angina, although concern about their possible role in changes to the heart (which may lead to heart failure) in patients who have had a myocardial infarction has limited their use.

Nitrate products have a direct action on vascular smooth muscle and cause it to relax. The effect is felt in both the arterial and venous circulation. In addition, nitrates increase the use of the other small blood vessels in the heart (collaterals) so that there is better oxygen supply to the inner layers of the heart muscleExamples: Nitroglycerin, Amlodipine (Norvasc), Diltiazem (Cardizem), Nifedipine (Procardia) and Verapamil (Calan)

Page 192: Pharmacology- Drug Cards (Index Cards)

NURSING PRECAUTIONS

Page 193: Pharmacology- Drug Cards (Index Cards)

* Use nitroglycerin cautiously in elderly patients, especially those who are volume depleted or taking several medications, because of the increased risk of hypotension and falls. Hypotension may be accompanied by angina and paradoxical slowing of the heart rate. Notify prescriber if these occur, and provide appropriate treatment, as ordered*For sublingual or buccal use, advise patient to place a tablet under her tongue or in her buccal pouch when angina starts and then to sit or lie down. Instruct her not to swallow drug, but to let it dissolve. Explain that moisture in her mouth helps drug absorption. If angina doesn’t subside, instruct patient to place another tablet under her tongue or in her buccal pouch after 5 minutes and to repeat, if needed, for three doses total. If pain doesn’t subside after 20 minutes, urge patient to call 911 or another emergency service* When applying transdermal ointment, apply correct amount on dose-measuring paper. Then place paper on hairless area of body and spread in a thin even layer over an area at least 2 inches by 3 inches. Don’t place on cuts or irritated areas. Wash your hands after application. Rotate sites. Store at room temperature* Open transdermal patch package immediately before use. Apply patch to hairless area, and press edges to seal.

*Rotate sites. Store at room temperature. If patient

needs cardioversion or defibrillation, remove transdermal patch* Be aware that I.V. nitroglycerin should be diluted only in D5W or normal saline solution and shouldn’t be mixed with other infusions. The pharmacist should add drug to a glass bottle, not a container made of polyvinyl chloride. Don’t use a filter because plastic absorbs drug. Administer with infusion pump* Frequently monitor heart and breath sounds, level of consciousness, fluid intake and output, and pulmonary artery wedge pressure, if possible* Assess patient for signs and symptoms of overdose, such as confusion, diaphoresis, dyspnea, flushing, headache, hypotension, nausea, palpitations, tachycardia, vertigo, vision changes, and vomiting. Treat as prescribed by removing nitroglycerin source, if possible; elevating the legs above heart level; and administering an alpha-adrenergic agonist, such as phenylephrine, as prescribed, to treat severe hypotension*Nurse should NOT rub nitro ointment into patient’s skin, it will be absorbed into their skin & causes a severe headache*Heart rate MUST be above 60

ANTICOAGULANTS & THROMBOLYTIC MEDICATIONHematologic products act in the formation, repair or function of red blood cells. They include the anticoagulants (heparin and Coumadin) and the heparin antagonist protamine sulfate. Thrombolytic agents and antiplatelet factors also have a major influence on blood clotting. Related vitamin and minerals that are needed for red blood cell development are iron, vitamin K, vitamin B12 and folic acid.

Anticoagulants: Warfarin (Coumadin), Heparin, Enoxparin (Lovenox)Warfarin (Coumadin): limit formation of blood coagulants factors in the liver by interfering with vitamin K. These drugs do not destroy existing blood clots; however, they may limit the extension of existing blood clots or thrombi. Heparin: acts at multiple sites in coagulation to stop reactions that lead to the clotting of blood and the formation of fibrin cloths. It increases coagulation factors to slow new clot development. Heparin does not dissolve existing clots either, although thrombolytic agents do.

Protamine & Phytonadione (Vitamin K): are proteins that act as a heparin antagonist to neutralize (reverse) the actions of heparin. However, it may also serve as an anticoagulant when used as the sole medication. In the presence of heparin, results will occur almost immediately and may persist for 2 hours or more

Thrombolyric Agents: convert plasminogen to the enzyme plasmin, which degrades or breaks down fibrin cloths, fibrinogen and other plasma proteins. The products are used for lysis or dissolving of thrombi.

Examples: Streptokinase (Streptase) Antiplatelet Agents: through a variety of mechanisms, these products act to limit or inhibit platelet

aggregation (clumping) and thus reduce thrombus formation. ASA reduces the incidence of myocardial infarction-related deaths in mean older than 50 years old. ASA is the drug of choice in ischemic stroke; it plays no role in hemorrhagic stroke. Clospidogrel (Plavix) is used for myocardial infarction prophylaxis for men and as additional or adjunct therapy with thrombolytics in preventing infarction or stroke.

CARDIOTONIC MEDICATION Cardiotonics make the heart beat stronger and slower. These drugs are also call cardiac

glycodsides. All cardiotonic have the following two acitons:-They increase the strength or force of the contraction (or pumping) of the heart muscle (myocardium).-They slow the heart rate

The normal heart pumps oxygenated blood from the left ventricle out through the body. If the heart is weak, less oxygenated blood can be pumped out with each contraction or beat of the heart. When cardiac output (the amount of blood pumped out with each heartbeat x HR) decreases, other organs are affected.

Example: Digoxin (Digitek, Lanoxin) Digoxin-Specific Antidote: Digoxin Immune Fab (Digibind) given for massive digoxin overose.

It binds with digoxin or digitoxin molecules. The resulting complex is excreted through the kidneys.

* Before administering digoxin immune Fab to high-risk patient, test for allergic reaction. After 20 minutes, observe for an urticarial wheal surrounded by erythema. Test is considered positive if it produces a wheal surrounded by erythema. If test causes a systemic reaction, apply tourniquet above test site, notify prescriber, and prepare to respond to anaphylaxis. Be aware that if a skin or systemic reaction occurs, additional drug shouldn’t be given unless essential; if more of the drug must be given, expect prescriber to pretreat patient with corticosteroids and diphenhydramine. Prescriber should be on standby to treat anaphylaxis* When administering to a child, watch for fluid volume overload* When giving a large dose, expect a faster onset but watch closely for febrile reaction* Monitor serum potassium level often, especially during first few hours of therapy. The potassium level may drop rapidly

GASTROINTESTINAL MEDICATIONS There are 3 major types of GI medications.

o The first major type includes the products designed to help restore or maintain the lining that protects the GI tract. These drugs include:

Antacids, which act to neutralize or reduce aciditiy of the gastric contents Histamine H2-receptor antagonists, which reduce gastric acid secretion by

limiting the action of histamine at the H2 receptors in the stomach, Proton pump inhibitors, which reduce gastric acid by blocking the proton

pump.o A second major type of GI medication affects the general motility, or movement, of

the GI tract. These medications include: Anticholinergics and antispasmodics, which not only reduce gastric

motility by also decrease the amount of acid secreted by the stomach. Antidiarrheals, which help reduce diarrhea by slowing the intestinal

peristalsis.o The third major type of GI drugs also affect motility, but their action is primarily in

the colon. These are the laxative agents. These prepareations promote bowel emptying in a variety of ways. They may increase intestinal bulk, lubricate the intestinal walls, soften the fecal mass by retaining water, or produce increase peristalsis through local tissue irritation or by direction action on the intestine.

ANTIPSYCHOTIC DRUGS (Lithium, Haldol, Compazine, Abilify, Zyprexa, Seroquel, Risperdal)

o Antipsychotic medications are administered to patients experiencing a psychotic disorder. Psychosis refers to a group of symptoms that affect mood and behavior

Hallucinations (false sensation or perceptions have no basis in reality) Delusions (false beliefs that cannot be changed with reason) Disorganized speech Behavior disturbances, social withdrawal Flatten affect (absence of an emotional response to any

situation/condition) Anhedonia (finding no pleasure in activities that are normally

pleasurableo Antipsychotics are usually given to bipolar disorder patients during an manic phase:

During the manic phase, the person experiences altered thought processes, which can lead to bizarre delusions

o Antipsychotic diminished the frequency and intensity of hyperactive (manic) episodes

Page 209: Pharmacology- Drug Cards (Index Cards)

LithiumHaloperidol Prochlorperazine Aprpiprazole(Haldol) (Compazine) (Abilify)Olanzapine Quetiapine Risperidone(Zyprexa) (Seroquel) (Risperdal)

ACTION Antipsychotic

USES Acute & Chronic psychoses, such as schizophrenia Bipolar (manic-depressive) illness Agitated behaviors associated with dementia

ADVERSE REACTIONS*Sedation, headache, hypotension, dry mouth, nasal congestion, urticaria, photophobia, photosensitivity*Possible behavioral changes: possible increase of intensity of psychotic symptoms (paradoxical effects), lethargy, hyperactivity, paranoid reactions, agitation and confusion

Extrapyramidal Syndrome (EPS): a group of adverse reactions that affects posture, promotes smooth and uninterrupted movement of carious muscle groups. Causes abnormal muscles movements:

o Parkinson-like symptoms: fine tremors, muscle rigidity, masklike appearance of face, slowness of movement, slurred speech and unsteady gait

o Akathsia: extreme restlessness and increased motor activity

o Dystonia: facial grimacing and twisting of the neck into unnatural positions

Tardive Dyskinesia (TD): a syndrome consisting of irreversible, involuntary dyskinetic movements, characterized by: rhythmic, involuntary movements of the tongue, face, mouth or jaw and sometimes the extremities. The tongue may protrude and there may be chewing movements, pucking of the mouth and facial grimacing.

o Because of the risk of TD, it is best to use the smallest dose & shortest duration of treatment that produces satisfactory clinical response.

Neuroleptic Malignant Syndrome (NMS): a rare reaction, characterized by a combination of EPS effects, hyperthermia and autonomic disturbances. It typically occurs within 1 month after the antipsychotic drug regimen is begun. NMS is potentially fatal and requires intensive symptomatic treatment, once the drug is discontinued recover occurs within 7-10 days.

o Shaking, involuntary movements + fever = NMS (FATAL)

CONTRAINICATIONS*Comatose patients, those who are severely depressed, have bone marrow depression, Pakinson’s disease, liver impairment, coronary artery disease, or severe hypo OR hypertension

Page 210: Pharmacology- Drug Cards (Index Cards)

*Antipsychotics should be used only when clearly needed and when the potential benefit outweighs any potential harm to the fetus*Used cautiously in patients with respiratory disorders, glaucoma, prostate hypertrophy, epilepsy, decreased renal function and peptic ulcer disease.

INTERACTIONSDrug:Anticholingeric drugs increased risk for TD & psychotic symptomsAntacids decreased effectiveness of lithiumLoop Diuretics increased risk for lithium toxicity, since increased urination & fluid removalLi combined with other antipsychotics increased risk of Li toxicityAlcohol increased risk for CNS depression

NURSING PRECAUTIONS*In combative patients or those who have serious manifestations of acute psychosis (example: hallucinations or lost of contact with reality), parenteral administration may be repeated every 1 to 4 hours until the desired effects are obtained. The nurse monitors the patient closely for cardiac arrhythmias or rhythm changes or hypotension

*Gerontology: older adults are at increased risk for Li toxicity because of a decreased rate of excretion. Lower dosages may be necessary to decrease the risk of toxicity.-Because drug metabolism and excretion are altered in elderly or debilitated patients, doses may be instituted at one-half to one-third the recommended dose for younger adults and increased more gradually than in younger adults.Special Considerations for Lithium *It is rapidly absorbed after oral administration. *Most common adverse reactions include: tremors, nausea, vomiting, thirst and polyuria.*Desirable serum Li levels = 0.6 – 1.2 mEq/L Lithium Toxicity

1.5-2 mEq/L = N/V/D, drowsiness, weakness, lack of coordination

2-3 mEq/L= Giddiness, blurred vision, tinnitus, vertigo, confusion, agitation/manic behavior, twitching of limbs

>3 mEq/L= multiple organ/system failure, seizures, arrhythmias, hypotension, muscle group twitching, spasticity, coma
