Zocor (Simvastatin) Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI 104490 • NDC 78206-180

As a proprietary hmg-coa reductase inhibitor presentation registered by Organon LLC, Zocor supplies active moiety Simvastatin (cross-referenced at /meds/simvastatin) in 10 mg/1 Tablet, Film Coated; 20 mg/1 Tablet, Film Coated (NDC 78206-180, 78206-182; SPL 2025-03-28). Clinical prescribing and dispensing guidelines focus on 1 Indications and usage zocor: ® is indicated: To reduce the risk of total mortality by reducing risk of coronary heart.

The active constituent inside Zocor—Simvastatin—functions as a targeted hmg-coa reductase inhibitor agent involving CYP3A4/OATP1B1 clearance pathways. While therapeutic target engagement mirrors generic Simvastatin, Zocor (registered by Organon LLC, SPL 2025-03-28) specifies proprietary packaging (78206-180, 78206-182) and 10 mg/1 Tablet, Film Coated; 20 mg/1 Tablet, Film Coated quality controls alongside a $9.7294/unit NADAC acquisition baseline.

Following administration (10 mg/1 Tablet, Film Coated), Zocor (Simvastatin) achieves Estimated 53%–65% oral systemic absorption for Zocor (Simvastatin) bioavailability and peak plasma concentration (tmax) reached 1–3 hours post-dose for zocor (simvastatin) onset, governed by a Approximately 6–18 hours terminal plasma half-life for Zocor (Simvastatin) terminal half-life through hepatic oxidation via cyp3a4/oatp1b1 followed by renal and biliary excretion of zocor (simvastatin) metabolites.

Before initiating Zocor (Simvastatin) at 10 mg/1 Tablet, Film Coated, clinical safety checklists rule out documented intolerance or hypersensitivity reaction involving simvastatin (hmg-coa reductase inhibitor); concurrent restricted medications flagged in section 4/7 of the zocor (simvastatin) dailymed monograph (104490). Logged tolerability patterns center on nausea (12% of reports), headache (10.6% of reports), nasopharyngitis (8.7% of reports).

CYP450 & Metabolic Pathways: CYP3A4 OATP1B1
Key Monitored Interactions:
Warfarin & Vitamin K Antagonists Major

Concurrent Zocor (Simvastatin) exposure alters anticoagulant pharmacodynamics, requiring closer hemorrhagic surveillance.
