Background

Nicardipine hydrochloride (YC-93) is a calcium channel blocker with an IC50 of 1 μM for blocking cardiac calcium channels. Nicardipine hydrochloride acts as an agent for chronic stable angina and for controlling blood pressure[1].

Nicardipine (0.1-10 μM; 24-48 h) reduces viability and proliferation of vascular smooth muscle cells (VSMCs) and inhibits their ability to migrate[2].

Nicardipine (0.3-10 mg/kg; p.o.) shows antihypertensive properties[3]. LD50s of Nicardipine are 643 mg/kg (oral) and 557 mg/kg (oral); 18.1 mg/kg (intravenous) 25.0 mg/kg (intravenous); 735 mg/kg (subcutaneous) and 683 mg/kg (subcutaneous); 171 mg/kg (intraperitoneally) and 155 mg/kg (intraperitoneally) for male and female Sprague-Dawley rats, respectively[3]. LD50s of Nicardipine are 187 mg/kg (oral) and 15.5 mg/kg (intravenous) for male Wistar rats, respectively[3]. LD50s of Nicardipine are 634 mg/kg (oral) and 650 mg/kg (oral); 20.7 mg/kg (intravenous) 19.9 mg/kg (intravenous); 540 mg/kg (subcutaneous) and 710 mg/kg (subcutaneous); 144 mg/kg (intraperitoneally) and 161 mg/kg (intraperitoneally) for male and female mice, respectively[3].
