Abstract
The effect of various topical anesthetics and their preservatives on the growth of Pseudomonas aeruginosa, Staphyloccoccus albus, and Candida albicans was investigated. The topical anesthetics were proparacaine HCl, tetracaine HCl, cocaine HCl, and benoxinate HCl. The preservatives were chlorobutanol and butyl p-hydroxybenzoate. Proparacaine inhibited C. albicans but not P. aeruginosa or S. albus. All three test organisms were inhibited to varying degrees by tetracaine, benoxinate, cocaine, chlorobutanol, and butyl p-hydroxybenzoate.
