DILTZAC vs VERARD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diltiazem is a calcium channel blocker that inhibits calcium ion influx across cardiac and vascular smooth muscle cells, resulting in dilation of coronary and systemic arteries and decreased myocardial contractility and conduction velocity.
Verard (vericiguat) is a soluble guanylate cyclase (sGC) stimulator. It sensitizes sGC to endogenous nitric oxide (NO) and directly stimulates sGC independently of NO, thereby increasing cyclic guanosine monophosphate (cGMP) production, leading to vasodilation and anti-remodeling effects in the heart and vasculature.
Oral: 30-120 mg 3-4 times daily; maximum 480 mg/day. IV: 0.25 mg/kg over 2 min, then 0.35 mg/kg after 15 min if needed; continuous infusion 5-15 mg/hour.
400 mg orally twice daily for 14 days

Terminal elimination half-life: 3.5-5.0 hours (healthy adults). Prolonged in elderly (6-8 hours) and in hepatic impairment (10-12 hours).
Terminal elimination half-life 12-15 hours; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal: 60-70% as metabolites, 2-4% unchanged; Biliary/Fecal: 20-30% as metabolites.
Renal excretion (70% unchanged, 20% as inactive metabolites), biliary/fecal (10%).
