Lactose Intolerance
Lactose intolerance is the inability to digest lactose, a sugar in milk
and milk product. Lactose intolerance results from -galactosidase
(lactase) deficiency. Lactase is the enzyme necessary to metabolize
lactose. Lactose intolerance can lead to excess gas, cramping,
diarrhea, or severe allergic reaction. It is estimated that 55% of
Northern Europeans, 95% of North Americans, 90% of Asians are
lactose intolerant.
Lactose is still a commonly used excipient in pharmaceutical and
nutraceutical formulations. Alternative excipient choices preventthe need for using lactose in tablets. Alternative excipients, such as

About Cellulose
Powdered cellulose is from
renewable sources.
Cellulose is the most common
organic substance on earth. It
is part of nearly all plants and
some microorganisms. In our
daily life we find cellulose in
paper, packaging materials, hy-
gienic articles, and of course in
all plant derived food, for exam-
ple fruits and vegetables. Cellu-
lose is found in many pharma-
ceutical solid dosage forms as
binder or filler.
Trees are the primary cellulose source. So the raw material for our
powdered cellolose or microcrystalline comes from different wood
sources.

Cellulose for Pharmaceutical Use
As ment ioned abov e, the cell ulos e is primari ly used for phar ma-ceuticals.
Native cellulose shows two different areas, crystalline and amor-
phous. The crystalline region is an area where the cellulose chains
are ordered. In the amorphous region the cellulose chains are
randomly ordered.
As a phar maceutic al exci pien t, two types of cellulose are in use,
powdered and microcrystalline. Both are derived from raw
cellulose.
During microcrystalline cellulose manufacture, most of the amor-
phous area is removed. Powdered cellulose is not chemically modified,
so amorphous material remains. During powdered cellulose manu-
facture, the raw cellulose is washed, milled, sieved and adjusted
to a specific particle size distribution.

bonds with each other, holding the chains firmly together and con-
tributing to their high tensile strength (Figure 2). Given a cellulose
material, the portion that does not dissolve in a 17.5% solution of
sodium hydroxide at 20 C is cellulose, which is true cellulose,
primarily used for pharmaceuticals; the portion that dissolves and
then precipitates upon acidification is -cellulose; and the portion
that dissolves but does not precipitate is -cellulose. For humans
this material is absolutely inert, not absorbable and noncaloric.
Additio nall y, the cell ulos e is not a good medi um for
microorganisms which decreases the risk of microbial spoilage.

Cellulose (C H O )n is a long-chain polymeric polysaccharide carbo-
hydrate, of monomers
1 > 4 glycosidic bonds by conden-
sation. This forms a straight chain polymer which molecule adopts
an extended rod-like conformation. The degree of polymerization
gives the average number of the residues in the chain. In microfibrils,
the multiple hydroxyl groups on the glucose residues form hydrogen
