CLINICAL PHARMACOLOGY
Ranitidine is potent histamine H2 receptor antagonist
and inhibits gastric acid secretion elicited by histamine.
Ranitidine also inhibits acid secretion elicited by
gastrin and, to a lesser extent, by muscarinic agonists.
Ranitidine inhibits basal and nocturnal acid secretion
and that stimulated by food, fundic distention, and
various drugs, It reduces both the volume and acid concentration
of gastric juice. The output of pepsin and secretion
of intrinsic factor are reduce.
Ranitidine is readily absorbed from the gastrointestinal
tract with pack concentrations in plasma occuring about
2 to 3 hours after oral administration. The bioavailability
of ranitidine is about 50% due to first-pass metabolism.
The elimination half-life from plasma is around 2 to
3 hours and ranitidine is weakly bound to plasma protein
(about 15%). A small proportion of ranitidine is metabolized
in the liver and is excreted unchanged in the urine.
Ranitidine crosses the placental barrier and is excreted
into breast milk.
