Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It causes vasodilation and decreases systemic vascular resistance.
Diltiazem inhibits calcium ion influx across cardiac and vascular smooth muscle cells, resulting in dilation of coronary arteries and peripheral arterioles, and reduction of myocardial contractility and heart rate.
Intravenous infusion: initial dose 5 mg/hour, titrate by 2.5-5 mg/hour every 15-30 minutes as needed; maximum 15 mg/hour. Oral: 20 mg three times daily initially, then 30-40 mg three times daily.
Oral, 120 mg or 180 mg once daily. For hypertension, initiate at 120 mg once daily; for angina, initiate at 180 mg once daily. Maximum dose: 360 mg once daily.

2 to 4 hours in healthy subjects; increased in hepatic impairment (up to 7 hours) and in elderly. No significant change in renal impairment.
3-5 hours (immediate-release) for diltiazem; after TAZTIA XT extended-release, effective half-life is approximately 7-9 hours due to prolonged absorption. Clinical context: steady state achieved in 3-5 days.
Primarily hepatic metabolism to inactive metabolites; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites accounts for approximately 60-70% of total elimination, with renal excretion of metabolites approximately 30-40%.
Renal (approximately 60% as unchanged drug and metabolites, primarily via glomerular filtration and tubular secretion), biliary/fecal (approximately 30-35%)
