Objective: The aim of of this study was to estimate the effectiveness and tolerance of Gynipral (hexoprenaline)-beta-2 sympathomimetic used as oral and intravenous tocolytic.
Material and methods: We analysed 110 pregnant women admitted to the hospital with premature uterus contractions between 17 and 37 week of pregnancy. Pregnant women were divided into two groups. Group I--86 patients with regular uterus contractions. In this group Gynipral was administered to suppress uterus contractions. Group two consisted of 24 patients without regular uterus contractions. In this group women were treated with Gynipral to keep pregnant uterus in maximum relaxation in such cases as IUGR, oligohydramnion, after Strassman procedure before pregnancy or cerclage procedure in current pregnancy. Group I was treated with intravenous Gynipral infusion and after suppression of uterus contractions the way of administration was changed into oral. Group II from the beginning was treated with oral tocolysis with Gynipral. Pregnant women were continually under CTG control and all ailments such as tachycardia, flapping tremor and anxiety were analysed and noted.
Results: Gynipral has effectively suppressed premature uterus contractions in 80 cases in group I (93%) and in 24 cases in group II (100%). In 106 cases (96%) patients have not presented any side effects.
Conclusions: Gynipral is an effective tocolytic successfully used in premature labor treatment. Gynipral has a good tolerance administered both intravenously and orally as well and in most cases there was no need to add antiarrhythmic drugs to reduce side effects.
