ACETASOL vs VOSOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetasol (acetic acid otic) is an antibacterial and antifungal agent that acts by acidifying the ear canal and inhibiting the growth of microorganisms. The acidic pH disrupts bacterial and fungal cell membranes and metabolism.
VOSOL (acetic acid otic solution) exerts antifungal and antibacterial activity by lowering the pH of the ear canal to approximately 3.0, creating an acidic environment that inhibits the growth of Pseudomonas aeruginosa, Staphylococcus aureus, and various fungi. Acetic acid disrupts bacterial cell wall synthesis and fungal membrane integrity, and also acts as a keratolytic agent to remove debris.
2-4 drops in the affected ear(s) every 2-4 hours as needed, otic route. Maximum 48 hours of continuous use.
Instill 5 drops into the ear canal every 2-3 hours while awake, then reduce to 4-6 times daily as symptoms improve.

12-24 hours; increased to 30-50 hours in renal impairment (CrCl <30 mL/min)
Terminal elimination half-life: 7-9 hours; clinically, steady-state is achieved after approximately 2 days.
Renal: 80-90% as unchanged drug; biliary: <5%
Renal excretion: ~50-70% as unchanged drug and metabolites; biliary/fecal: ~20-30%.
