polyethylene glycol, povidone, talc,
and titanium dioxide.
CLINICAL PHARMACOLOGY
Penicillin V exerts a bactericidal action against penicillin-sensitive
microorganisms during the stage of
active multiplication. It acts through the inhibition of biosynthesis
of cell-wall mucopeptide. It is not
active against the penicillinase-producing bacteria, which include
many strains of staphylococci. The
drug exerts high _in vitro_ activity against staphylococci (except
penicillinase-producing strains),
streptococci (groups A, C, G, H, L and M), and pneumococci. Other
organisms sensitive _in vitro_ to
penicillin V are _Corynebacteriumdiphtheriae, Bacillus anthracis,
Clostridia, Actinomycesbovis,_
_Streptobacillusmoniliformis, Listeria monocytogenes, Leptospira, and
Neisseria gonorrhoeae._
_Treponemapallidum_ is extremely sensitive.
The potassium salt of penicillin V has the distinct advantage over
penicillin G in resistance to
inactivation by gastric acid. It may be given with meals; however,
blood levels are slightly higher when
the drug is given on an empty stomach. Average blood levels are two to
five times higher than the
levels following the same dose of oral penicillin G and also sh
