Optical Activity UNSPECIFIED

Ergonovine (also known as ergometrine) is the active water soluble component of ergot of rye. Ergonovine is being used as a maleate salt to prevent or treate postpartum haemorrhage and postabortion haemorrhage. Ergonovine stimulates alpha-adrenergic and serotonin receptors, thus activating contractions of uterine and vascular smooth muscle. Ergonovine may have depressant effect on CNS system as it binds to dopamine receptors.

Sample Use Guides

Prophylaxis of postpartum haemorrhage and postabortion haemorrhage: the immediate postpartum dose of ergonovine (ergometrine maleate) is 200 ug administered intramuscularly. The injection should not be given until completion of the delivery is assured, and until the possibility of a second twin has been excluded. In an emergency situation, 200 ug may be injected intravenously. IV doses should be given slowly, over a period of at least 1 min. Treatment of postpartum haemorrhage and postabortion haemorrhage: 200 ug may be injected intramuscularly.
