Nisoldipine is a pharmaceutical drug used for the treatment of chronic angina pectoris and hypertension. It is a calcium channel blocker of the dihydropyridine class. It is sold in the United States under the proprietary name Sular. Nisoldipine has tropism for cardiac blood vessels.^[1]

It was patented in 1975 and approved for medical use in 1990.^[2]

Contraindications

Nisoldipine is contraindicated in people with cardiogenic shock, unstable angina, myocardial infarction, and during pregnancy and lactation.^[3]

Adverse effects

Common side effects are headache, confusion, fast heartbeat, and edema. Hypersensitivity reactions are rare and include angioedema.^[3]

Interactions

The substance is metabolized by the liver enzyme CYP3A4. Consequently, CYP3A4 inducers such as rifampicin or carbamazepine could reduce the effectiveness of nisoldipine, while CYP3A4 inhibitors such as ketoconazole increase the amount of nisoldipine in the body more than 20-fold. Grapefruit juice also increases nisoldipine concentrations by inhibiting CYP3A4.^[3]

Pharmacology

Mechanism of action

Nisoldipine is a calcium channel blocker that selectively inhibits L-type calcium channels.^[3]
