PPT-part I PENICILLINS Penicillins

DRUG ACTION The penicillins are bactericidal and act by interfering with bacterial cell wall synthesis They diffuse well into body tissues and fluids but penetration into the cerebrospinal fluid is poor except when the meninges are inflamed They are excreted in the urine in therapeutic concentrations. 13/02/13.
