title: Interaction of aminoglycoside antibiotics with oxytocin and prostaglandin E2 on uterine contractility.
abstract: In the present study the interaction of aminoglycoside antibiotics with oxytocin and prostaglandin E2 on the contractility of the rat uterus was investigated. It was found that oxytocin and prostaglandin E2 were able to completely reverse the uterine relaxing effect of aminoglycoside antibiotics and when administered concomitantly they exert a protective action. These findings support the view that aminoglycoside antibiotics affect superficially bound extracellular calcium only, since oxytocin and prostaglandins primarily act on intracellular calcium.
