Zovirax (Acyclovir) Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI 307730-B01870994 • NDC 0187-0994

As a proprietary herpes simplex virus nucleoside analog dna polymerase inhibitor presentation registered by Bausch Health US, LLC, Zovirax supplies active moiety Acyclovir (cross-referenced at /meds/acyclovir) in 50 mg/g Cream; 50 mg/g Ointment (NDC 0187-0994, 0187-0993; SPL 2024-12-31). Clinical prescribing and dispensing guidelines focus on Herpes Zoster Infections: Acyclovir tablets, USP are indicated for the acute treatment of herpes zoster (shingles).

The active constituent inside Zovirax—Acyclovir—functions as a targeted herpes simplex virus nucleoside analog dna polymerase inhibitor agent with class-characteristic hepatorenal disposition. While therapeutic target engagement mirrors generic Acyclovir, Zovirax (registered by Bausch Health US, LLC, SPL 2024-12-31) specifies proprietary packaging (0187-0994, 0187-0993) and 50 mg/g Cream; 50 mg/g Ointment quality controls alongside a $0.1070/unit NADAC acquisition baseline.

Following administration (50 mg/g Cream), Zovirax (Acyclovir) achieves < 5% transdermal or mucosal systemic uptake from Zovirax (Acyclovir) bioavailability and initial local symptom modulation in 30–90 minutes; full tissue response over 1–3 weeks (zovirax (acyclovir)) onset, governed by a Localized tissue retention for Zovirax (Acyclovir) with minimal systemic plasma half-life terminal half-life through local esterase/enzymatic cleavage of zovirax (acyclovir) with minimal hepatic cytochrome burden.

Before initiating Zovirax (Acyclovir) at 50 mg/g Cream, clinical safety checklists rule out documented intolerance or hypersensitivity reaction involving acyclovir (herpes simplex virus nucleoside analog dna polymerase inhibitor); concurrent restricted medications flagged in section 4/7 of the zovirax (acyclovir) dailymed monograph (307730-b01870994). Logged tolerability patterns center on nausea (10.8% of reports), headache (6.7% of reports), dizziness (6% of reports).

Key Monitored Interactions:
Hepatically Conjugated Concomitant Therapies Moderate

Assess baseline hepatic panels and interacting prescriptions when starting Zovirax (Acyclovir) (herpes simplex virus nucleoside analog dna polymerase inhibitor).

Gastric pH-Altering Agents (PPIs & H2 Blockers) Minor

Shifts in intragastric pH can modestly influence dissolution kinetics of oral Zovirax (Acyclovir) dosage forms.
