The survival of S. aureus on solid dosage forms decreased with increased temperature, relative humidity, storage time, and inoculum concentrationThe bacteria did not survive on pure or buffered aspirin, a nasal decongestant, a barbiturate-analgesic combination, methocarbamol with aspirin, magnesium hydroxide, quinidine, or pentaerythrital tetranitrate tablets.The survival rate on gelatin capsules and magaldrate was 8% and 5%, resp.S. aureus did not survive in water beyond the pH range of 4.0-8.6.Maximum survival was at pH 7.0-8.0.
