Penicillanoyloxymethyl penicillanate 1,1,1',1'-tetraoxide is useful for enhancing the activity of betalactam antibiotics in the treatment of bacterial infections in mammalian subjects. A pharmaceutical composition comprising a suspension of penicillanoyloxymethyl penicillanate 1,1,1',1'-tetraoxide in water is disclosed which is particularly valuable for use with slow release forms of beta-lactam antibiotics. |
