CLINICAL PHARMACOLOGY
Methscopolamine bromide is an anticholinergic agent which possesses
most of the
pharmacologic actions of that drug class. These include reduction in
volume and total
acid content of gastric secretion, inhibition of gastrointestinal
motility, inhibition of
salivary excretion, dilation of the pupil and inhibition of
accommodation with resulting
blurring of vision. Large doses may result in tachycardia.
PHARMACOKINETICS
2,
4
Methscopolamine bromide is a quaternary ammonium derivative of
scopolamine. As a
class, these agents are poorly and unreliably absorbed.
Total absorption of
quaternary ammonium derivatives of the alkaloids is 10 to 25%. Rate of
absorption is
not available. Quaternary ammonium salts have limited absorption from
intact skin, and
conjunctival penetration is poor.
Little is known of the fate and excretion of most of
these agents.
