[Short-term tocolysis of prostaglandin induced uterine contractions comparison between fenoterol and diazoxide (author's transl)].

Uterine contractions were stimulated with a mean dose of 1500 microgram PG in seven pregnant patients between the 14th and 22nd week of pregnancy. The same patients received 300 mg Diazoxide and 20 or 30 microgram Fenoterol alternately in order to tocolize these uterine contractions. After injection of 20 microgram Fenoterol the mean contraction interval lasted for 3.4 min, whereas after 300 mg Diazoxide a mean interval of 48 min was achieved. Side effects after Fenoterol were more marked.
