DESCRIPTION
Nimodipine belongs to the class of pharmacological agents known as
calcium channel blockers.
Nimodipine is isopropyl 2 - methoxyethyl 1, 4 - dihydro - 2, 6 -
dimethyl - 4 - (m-nitrophenyl) - 3, 5 –
pyridinedicarboxylate. It has a molecular weight of 418.5 and a
molecular formula of C
H N O
The structural formula is:
Nimodipine is a yellow crystalline substance, practically insoluble in
water.
Nimodipine capsules are formulated as soft gelatin capsules for oral
administration. Each liquid filled
capsule contains 30 mg of Nimodipine USP in a vehicle of glycerin,
peppermint oil, purified water and
polyethylene glycol. The soft gelatin shell contains gelatin, D&C
Yellow #10, glycerin, titanium
dioxide and purified water. The ingredients in the edible imprinting
ink contain ammonium hydroxide,
black iron oxide, n-butyl alcohol, isopropyl alcohol, shellac glaze in
ethanol and propylene glycol. In
addition, the capsule may contain trace amounts of fractionated
coconut oil.
CLINICAL PHARMACOLOGY
MECHANISM OF ACTION:
Nimodipine is a calcium channel blocker. The contractile processes of
smooth muscle cells are
dependent upon calcium ions, which enter these cells during
depolarization as slow ionic

transmembrane currents. Nimodipine inhibits calcium ion transfer into
these cells and thus inhibits
contractions of vascular smooth muscle. In animal experiments,
nimodipine had a greater effect on
cerebral arteries than on arteries elsewhere in the body perhaps
because it is highly lipophilic,
allowing it to cross the blood-brain barrier; concentrations of
nimodipine as high as 12.5 ng/mL have
been detected in the cerebrospinal fluid of nimodipine-treated
subarachnoid hemorrhage (SAH) patients
