Stewardship Turns Non-Antibiotic Antiseptics Into Growth
Methenamine hydrolyses to formaldehyde in acidic urine rather than acting as an antibiotic, which means it applies no selective pressure and generates no resistance, and that is precisely the property guidelines now prioritise for prophylaxis in recurrent infection. Trial evidence supporting it against repeated antibiotic courses has moved practice. Growth at 12.3% follows a change in what medicine values rather than any change in the molecule, which has been available essentially unchanged since 1899. Nobody can patent it, so the benefit accrues to whichever manufacturer secures guideline inclusion first in each national system.
Market Impact: Costs $14 per prophylaxis month
