ranitidine hydrochloride (HCl),
USP, a histamine H2-receptor antagonist. Chemically it is
N[2-[[[5-[(dimethylamino)methyl]-2-
furanyl]methyl]thio]ethyl]-N'-methyl-2-nitro-1,1-ethenediamine, HCl.
It has the following structure:
[structure-ranitidine]
The empirical formula is C13H22N4O3S•HCl, representing a molecular
weight of 350.87.
Ranitidine HCl USP is a white to pale yellow, granular substance that
is soluble in water. It has a
slightly bitter taste and sulfur like odor.
Each ranitidine tablet USP 150 mg for oral administration contains 168
mg of ranitidine HCl USP
equivalent to 150 mg of ranitidine. Each tablet also contains the
inactive ingredients microcrystalline
cellulose, croscarmellose sodium, colloidal silicon dioxide, magnesium
stearate, FD&C Red # 40
Aluminum Lake, hypromellose, titanium dioxide, triacetin.
Each ranitidine tablet USP 300 mg for oral administration contains 336
mg of ranitidine HCl USP
equivalent to 300 mg of ranitidine. Each tablet also contains the
inactive ingredients microcrystalline

stearate, FD&C Red # 40
Aluminum Lake, hypromellose, titanium dioxide, triacetin.
Ranitidine is a competitive, reversible inhibitor of the action of
histamine at the histamine H2-receptors,
including receptors on the gastric cells. Ranitidine does not lower
serum Ca++ in hypercalcemic states.
Ranitidine is not an anticholinergic agent.
Pharmacokinetics:
Absorption:
Ranitidine is 50% absorbed after oral administration, compared to an
intravenous (IV) injection with
mean peak levels of 440 to 545 ng/mL occurring 2 to 3 hours after a
150-mg dose. Absorption is not
significantly impaired by the administration of food or antacids.
Propantheline slightly delays and
increases peak blood levels of ranitidine, probably by delaying
gastric emptying and transit time. In one
study, simultaneous
