Identification

Summary

Manidipine is a dihydropyridine calcium channel blocker used to treat hypertension.

Generic Name
Manidipine
DrugBank Accession Number
DB09238
Background

Manidipine (INN) is a calcium channel blocker (dihydropyridine type) that is used clinically as an antihypertensive. It is selective for vasculature and does not produce effects on the heart at clinically relevant dosages.

Pharmacodynamics

Manidipine produces vasodilation resulting in lower blood pressure 1.

Mechanism of action

Contraction of vascular smooth muscle is stimulated by Gq coupled receptors which produce calcium release from the sarcoplasmic reticulum. This is followed by opening of voltage dependent calcium channels and an influx of calcium into the cell ultimately producing contraction. Manidipine binds to and dissociates slowly from L- and T-type voltage dependent calcium channels on smooth muscle cells, blocking the entrance of extracellular calcium into the cell and preventing this contraction 1,2. This produces vasodilation which decreases blood pressure. Manidipine produces renal vasodilation and an increase in natriuresis. This likely contributes to the antihypertensive effect by reducing blood volume. Manidipine is selective for the vasculature and does not produce significant effects on the heart or central nervous system at clinically relevant dosages.

Absorption

The median Tmax is 1.5 h 1. Administration with food produces an 1.3-1.6-fold increase in Cmax but no change in Tmax. Manidipine does not accumulate significantly with multiple doses.

Volume of distribution

Not Available

Protein binding

Manidipine is 99% bound to human plasma proteins 1.

Metabolism

Manidipine is extensively metabolized by CYP enzymes to pyridine derivatives and diphenylmethane derivatives which make up 4-7% and 22-24% of the dose excreted in the urine 1.

Route of elimination

Manidipine is eliminated through extensive metabolism. 63% is eliminated in the feces and 31% in the urine as metabolites 1.

Half-life

The half life of elimination has been observed to be dose dependent 1. Doses of 5, 10, and 20 mg produced half lives of 3.94, 5.02, and 7.95 h respectively.
