Routes Of Parenteral AdministrationRoutes Of Parenteral AdministrationIntradermal (I.D.): Injections into the superficial layer of skin. Only

small volumes (0.1 ml) can be used. Absorption is slow by this route.

Subcutaneous (S.C., S.Q., Sub-Q, Hypo): Injections into the loose tissue

beneath the skin. Absorption is faster than intradermal

Intramuscular (I.M.): Injections into a muscle mass up to 5 ml can be

given

Intravenous (I.V.): Injection into a vein. There is little limitation on

volume and absorption in instantaneous.

Intra Muscular (I.M.):- Injection into a muscle mass up to 5ml can be

given

Intradermal (T.D.):- Injection into the loose tissue beneath the skin.

Only small volumes (0.1 ml) can be used

Intra-arterial

Intracardiac: -Injections into heart chamber.

Intrathecal (spinal fluid): Injection into spinal fluid.

Drugs given by the intraspinal route must be in solution. Drugs given

by the intravenous route must be in solution or emulsions. Drug given

by

subcutaneous, intramuscular or intradermal may be solutions,

suspensions or emultions.

Intrasynovial:- (joint fluid area): Injection into a joint fluid area.

Inttraspinal: Injection into a spinal column

Intra-articular:- Injections into a joint. This method is used for arthiritis

and joint injuries.

Vial Washing, Sterilizing And Depyrogenation Directive 21CFR part 211.92 states that containers used for parenteral

drugs, shall be "clean", "sterile" and "pyrogene free". This can be

accomplished by washing machines and sterilization/depyrogenation

equipment.

Washing contributes an critical role in pharmaceutical world. Hence to

understand ‘washing’, first lets understand the term “Clean”.

104

Page 37: History of Parenterals-1

CleanToday, most glass vials are of high quality and require little if any cleaning.

However after the manufacturing process, vials are subject to uncontrolled

environments and are likely to become contaminated with particulates and micro-

organisms. For this purpose, vial washers are used throughout the Pharmaceutical and

Biotech Industry.

The performance of a vial washer can be validated through two studies:

Particulate Removal

To determine the effectiveness of the vial washer, it is recommended to spike

vials with a styrene polymer bead suspension prior to washing. The vial washer should

be able to remove all particulates.

Chemical Contaminants Removal To test the ability to remove chemical contaminants, vials are spiked with a

Sodium Chloride (NaCl) solution. After washing, no traces of NaCl should be detected.

Principle The most effective way to remove contaminants from vials is through "scrubbing"

action with utilities. Most commonly used utilities for washing of vials are Purified Water

and Water For Injection (WFI), which is not only without particulates, but also without

microorganisms and pyrogenes. The "scrubbing" action is accomplished by high

pressure water jets.

The effectiveness of this "scrubbing" is a function of the following factors:

1) The energy level of the WFI

2) The amount of WFI used per vial.

Energy Level Of WFI The higher the WFI temperature, the higher the energy level. High temperature

WFI (80-90° C) is more effective in particulate removal than WFI at ambient

temperature. High pressure water jets are more effective than low pressure water jets.

105

Page 38: History of Parenterals-1

Amount Of WFI

The amount of WFI is subject to the size of the vial. Obviously, larger vials

require more WFI than smaller vials.

In a vial washing machine, the amount of WFI is determined by:

1) The cycle time (or speed setting) of the machine,

2) The number of spraying stations

3) The orifice of the spraying opening.

As WFI is part of the ongoing operational cost, it does not make sense to use

more WFI per vial than necessary. Ideally, the amount of WFI per vial should be

empirically determined.

Sterilizing And Depyrogenation Cleaning plays an important role but still our aim is to obtain a "clean", "sterile"

and "pyrogen free" parenteral drug. Thus sterilization and depyrogenation process even

contributes equally to achieve the goal. Lets understand sterilization and

depyrogenation in detail.

Sterile Vials can be sterilized in dry-heat ovens and sterilization tunnels. Dry-heat ovens

are designed to sterilize at a temperature of 170°C. Sterilizing tunnels are designed to

sterilize at twice that temperature.

Heat destroys microorganisms. The destruction process of micro-organisms is a

function of time and temperature. The rate of destruction is more or less logarithmic,

meaning that in a given time interval and at a given temperature, the same percentage

of the bacterial population will be destroyed. For example, if the time required to destroy

1-log cycle (90%) is known, and the desired thermal reduction has been decided (e.g. 4-

log), then the time required can be calculated.

106

Page 39: History of Parenterals-1

Example: If the bacterial population is 1 million CFU (Colony Forming Units),

and it takes 5 minutes to destroy 1-log cycle at a certain temperature, then

the remaining population after 5 minutes is 100,000 CFU, after 10 minutes

10,000 CFU, after 15 minutes 1,000 CFU and after 20 minutes 100 CFU (4-log

cycles).

Pyrogene Free

During the destruction of the cell-wall of bacteria (also called death-phase),

endotoxins are released. Endotoxins are pyrogenic (Gr: pur, gen. puros=fire,

gennaeo=to generate). When pyrogenes (inadvertently) enter the blood stream, white

blood cells are activated by encapsulating the pyrogenes. This process causes elevated

temperatures (fever) in humans and animals.

Pyrogenes are too small to be eliminated by filtration. However, heat will

disintegrate pyrogenes (high-molecular lipo-polysaccharides) to harmless molecules.

At 250°C, the time required to disintegrate pyrogenes 1-log cycle, is 5 minutes

(D-value). Empirically has been determined that for every 46.4°C. increase in

temperature, the D-value will be reduced by 1-log cycle.

In other words, at a temperature of 296.4°C, a 1-log pyrogene reduction is

accomplished after 30 seconds. At a temperature of 342.8°C., a 1-log pyrogene

reduction is accomplished after 3 seconds.

Types Of Tunnel Sterilizers

Two types of tunnels can be distinguished:

1) Radiant heat tunnels

2) Laminar Air Flow (LAF) tunnels.

Radiant heat tunnels use Infrared heating elements to heat vials by radiation.

Laminar Air Flow tunnels apply heated and filtered air to heat vials by convection. The

term "Laminar" is actually incorrect. There is little if any laminarity of air in a LAF tunnel.

It would be more appropriate to speak of "Hot Air" tunnels.

109

Page 42: History of Parenterals-1

Sterilizing/Depyrogenation tunnels consist of three chambers:

1) The infeed chamber

2) The sterilizing chamber

3) The cooling chamber

Advantages Of Hot Air Tunnels Over Radiant Heat

Tunnels

1) Heat transfer by convection is faster than by radiation. The sterilizing

chamber of a Hot Air tunnel can therefore be shorter that of a radiant heat

tunnel. This results in a smaller foot print.

2) Particulates generated by the vials and the tunnel itself (transport belt) are

continuously removed by HEPA filters. Hot Air tunnels are "cleaner" than

Radiant heat tunnels.

3) Better control of air over-pressure in the clean room by balancing the air

pressures in the three sections of the tunnel.

4) Better process control by automatically adjusting the air pressure and air

velocity per section.

Note 1:

Glass vials can be safely exposed to 350°C. Higher temperatures should be

avoided as the surface of the vials is subject to change. The result is

increased friction between vials which may adversely affect down stream

vial handling. The optimum working temperature of a sterilizing tunnel is

therefore 350°C.

Note 2:

Typically, sterilization/depyrogenation tunnels are validated at no less than

4-log pyrogene reduction. This includes a 1-log cycle safety margin.

Page 43: History of Parenterals-1

Filters

Each of the three sections of the tunnel is equipped with High Efficiency

Particulate Air (HEPA) filters. HEPA filters are 99.99% effective regarding 3µ

particulates. In the sterilizing chamber, heat resistant HEPA filters are used with an

efficiency of 99.97%.

DOP Testing

HEPA filters are tested for efficiency by the "DOP" test procedure. DOP stands

for Di-Octyl Phlalate. Because of concerns that DOP may have carcinogenic properties,

it has been substituted by a compound called Emery 3004, although the acronym DOP

has been retained. Each section of the tunnel has provisions to conduct the DOP test.

Automatic Door Setting

The three sections of the tunnel are separated by doors. The height setting of

these doors depends on the height of a vial and is automatically set by the PLC.

Vial Loading

Tunnels can be equipped with an external conveyor with vial loading system, to

be integrated with the outfeed of the upstream washing machine.

The tunnel conveyor is moved by an AC motor with frequency control. The

conveyor travel distance per loading stroke is subject to the vial diameter and is

controlled by the PLC.

Infeed Area

The purpose of the infeed area is to create a thermal barrier between the vial

washing room and the sterilizing chamber, and to dry and preheat the vials by means of

air flowing back from the sterilizing chamber.

Sterilizing Chamber

111

Page 44: History of Parenterals-1

Heat is generated by stainless steel, SCR-controlled heating elements.

Depending on the format, vials stay approximately 6-10 minutes in the

sterilizing/depyrogenation chamber. The recirculated hot air is blown at a speed of

approximately 0.7 m/s over the vials.

Cooling Chamber

Depending on the size of the tunnel. Regular tap water or chilled water can be

used to cool the surrounding environment. Depending on the size of the cooling zone

and the set speed of the conveyor, vials stay approximately 15-20 minutes in the

cooling chamber.

HMI (Humane Machine Interface)

The Humane Machine Interface provides the communication between the

operator and the equipment. The software package is used is designed according to

Title 21 Code of Federal Regulations (21CFR part 11).

Page 46: History of Parenterals-1

Operating Principle

Clean sterile vials loaded on outfeed dead plate of Tunnel are moved to the filling

machine on the delrin slat conveyor from the rotary Unscrambler. The vials are

transported on the conveyor to the filling stations in a row and are locked in by a infeed

starwheel. This infeed starwheel acts as an indexer, releasing four vials at a time. It also

controls alignment of the vials for the diving nozzles. After the vials are fillied, the

pumps(syringes) rotates to the suction mode, and the nozzles are in their original

[position, the starwheel gets unlock and allows four filled vials to move on before locking

again. The no vial machine stop arrange ment is made with the help of a proximity

device.

Note: The pump cylinders (syringes) are valve less type and self suctioned.

They do not require the reservoir manifold to be pressurized.

After filling, filled vials are transported to stoppering station through the conveyor.

Then the vials are precisely positioned to stoppering stations by a screw provided on

the conveyor. Stoppers are coming from an anticlockwise hopper, via a linear chute and

then transferred to a pickup transfer wheel. From transfer wheel the stoppers are picked

up by the Robotic Ferris wheel and the same robotic wheel will insert stoppers in the

vial neck. After stoppering , the vial will move under the stopper pressing wheel, where

the stoppers get fully pressed. The NO STOPPER- MACHINE STOP arrangement is

made with the help of a photocell device.
