Cardiovascular effects of terbutalin in pregnant women

Abstract
Terbutaline, a .beta.-mimetic drug, appears to have a favorable .beta.2:.beta.1 ratio. It is suitable for uterine relaxation. Ten normotensive pregnant women with imminent premature labor were studied during i.v. infusion of terbutaline with the non-invasive method of quantitative sphygmometry. Cardiac output increased and total peripheral resistance decreased. As there was only slight variation in the arterial blood pressure, terbutaline is indicated especially in cases with hypotension.
