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

Contraindications

edit

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

Adverse effects

edit

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

Interactions

edit

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

edit

Mechanism of action

edit

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