Epitome of the Pharmacopeia of the United States and the National Formulary Part 61

=*Pepsinum (Pepsin.), Pepsin, U.S.P.=--Contains a proteolytic ferment or enzyme from the stomach of the hog.

White or yellowish scales, grains, or powder, having a slightly acid or saline taste and no offensive odor. Soluble in water (1:50); nearly insoluble in alcohol. Digests 3000 times its own weight of coagulated egg alb.u.men.

ACTION AND USES: Used to a.s.sist in the gastric digestion of proteins. Usually superfluous, since gastric juice generally contains sufficient pepsin to perform gastric digestion.

The alcohol of the elixirs and wines may be distinctly harmful in gastric disorders, while the other ingredients of the many complex mixtures need be prescribed only when direct indications for them exist. Many of these mixtures are irrational.
