Introduction :
also very useful for cervical ripening and induction of Post partum haemorrhage (PPH) is a serious labour. 6,7 It is also used in 1st and 2nd trimester obstetrics problem and primary PPH is said to occur abortion and has been shown in several randomised in about 5-8% of deliveries.1 Maternal mortality in placebo controlled trial to significantly reduce risk of Bangladesh is about 3 per 1000 live birth.2 Among PPH and also control of PPH.6 It is stable at room the other causes haemorrhage ranging 20-25% of temperature, low cost, easily administrable, available cause of maternal mortality and 12% due to in tablet form and definitely advantageous than the other PGs with few systemic side effect. Its haemorrhage. PPH is one of the leading cause of absorption is rapid and effect on the post partum maternal mortality in developing country. 3,4 The common cause of PPH is uterine atony (80%).1 The Our aim was to show the effectivity of oral underlying principle in active management is to misoprostol versus oxytocin for the active excite powerful uterine contraction following birth of management of third stage of labour to reduce the risk the head or anterior shoulder of the baby, which minimise the blood loss in third stage approximatelyto 1/ Materials and Methods :

Conclusion :
Misoprostol, is a synthetic PGE1. analogue. Its FDA Oral misoprostol is as effective as intramascular approved indication is for the prevention of stomach oxytocin in the prevention of PPH. So, oral ulcer in patient taking non steroidal anti-inflamatory misoprpstol can replace intramascular oxytocin in the drugs. Because of its prostaglandin activity it is also active managment of third stage of labour in low risk used for reducing the risk of PPH and also to control women in developing countries especially as it is of PPH.6,7 It is available in tablet form and can be administered orally and it is thermostable in tropical given orally and rectally for the active management ofthird stage of labour. In this study, we gave 400 conditions. Shivering and transient pyrexia were microgram (μgm) of misoprostol orally in one group specific side effects of misoprostol which has (n=210) and intramascular oxytocin 10 I.U. in another potential in reducing the high incidence of PPH in group (n=190).
