Piridicillin is the semi-synthetic penicillin. It has exhibited broad-spectrum activity in vitro against gram-positive cocci, except penicillin G-resistant Staphylococcus aureus, and against gram-negative bacilli. Piridicillin is reported to be more active in-vitro than piperacillin, azlocillin or ticarcillin against Ps. aeruginosa. It is unstable at alkaline pH and displays marked inoculum independence.
