Buccal prostaglandin E2 for induction of labour.

The administration of buccal prostaglandin E2 (PGE2) was evaluated in 30 patients; effective uterine stimulation occurred in 90 per cent of those receiving a dose of 1 mg hourly. Two patients had a prolonged contraction on a single occasion during labour. The unpleasant taste of the tablets and a high incidence of nausea and vomiting indicated that buccal prostaglandins had no advantages over other methods of administering oxytocic agents.
