Nitrendipine
Nitrendipine is a calcium channel blocker of the dihydropyridine class. It is used in the treatment of hypertension and angina pectoris.
Mechanism of Action[edit | edit source]
Nitrendipine inhibits the influx of extracellular calcium through myocardial and vascular membrane pores by physically plugging the channel. The decrease in intracellular calcium inhibits the contractile processes of the myocardial smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.
Indications[edit | edit source]
Nitrendipine is indicated for the management of hypertension. It may be used alone or in combination with other antihypertensive agents.
Side Effects[edit | edit source]
Common side effects of Nitrendipine include headache, dizziness, flushing, and nausea. Serious side effects may include low blood pressure, heart failure, and arrhythmias.
Contraindications[edit | edit source]
Nitrendipine is contraindicated in patients with known hypersensitivity to dihydropyridines.
Drug Interactions[edit | edit source]
Nitrendipine may interact with other drugs such as beta blockers, digoxin, cimetidine, and warfarin.
Dosage[edit | edit source]
The usual starting dose of Nitrendipine is 10 mg once daily. The dose may be increased according to the patient's response.
