Verapamil inhibits calcium ion influx across cardiac and smooth muscle cells, blocking L-type calcium channels, leading to vasodilation and negative chronotropic, dromotropic, and inotropic effects.
No established standard dosing. Veraring is not a recognized pharmaceutical agent.
Hypertension: 120-240 mg ER orally once daily; maximum 480 mg/day. Angina: 80-120 mg IR orally three times daily; ER 180-360 mg once daily.

Terminal elimination half-life: 4.5 hours (range 3.5-6.0 hours). Clinical context: Steady state achieved within 24 hours; no accumulation with normal renal function.
Terminal elimination half-life is 2.8 to 7.4 hours in healthy adults, prolonged in hepatic impairment or elderly (up to 12 hours).
Renal elimination of unchanged drug and metabolites: 70% (60% unchanged, 40% as glucuronide conjugate); biliary/fecal: 30% (primarily metabolites).
Renal excretion accounts for approximately 70% of elimination, with 3-4% as unchanged drug. Fecal elimination accounts for about 25%, predominantly via biliary secretion.
