The beta 2-sympathomimetic drug fenoterol (fenoterol hydrobromide, CAS 1944-12-3, Partusisten) is routinely used to inhibit uterine contractions (tocolysis). Investigations of plasma concentrations of those receiving i.v. or oral tocolysis often show different results, both within particular groups of pregnant women and in comparison with non-pregnant persons. The aim of this study was to determine the pharmacokinetics of fenoterol in pregnant women, an important factor which so far had not been known. Four healthy pregnant women with similar weight and gestational age and all with premature labor were administered a continuous intravenous infusion of 4 micrograms fenoterol/min. During and up to 24 hours after the end of the infusion, venous blood samples were taken in order to determine the fenoterol plasma concentrations by radioimmunoassay. From a steady state concentration (css) of 2242 +/- 391 pg/ml (x +/- S.E.), a non-linear two-phased plasma elimination was seen with half-lives t1/2 of 11.40 min and 4.87 h. The area under the plasma concentration-time curve (AUC0-12h) was 6.27 ng/ml x h. The total clearance (Cltot) was 114.8 l/h. These data are nearly the same as the data already known for healthy non-pregnant (male) volunteers. The deviations which are seen in the plasma concentrations in pregnant women in comparison to non-pregnant persons during or after continuous i.v. infusion can therefore not be caused by differences in the pharmacokinetics. Other factors, however, such as body weight and/or gestational age, might influence the results.
