Ritodrine and terbutaline compared for the treatment of preterm labor. 1985

T S Kosasa, and R T Nakayama, and R W Hale, and G S Rinzler, and C A Freitas

A prospective study comparing intravenous ritodrine and terbutaline was initiated to assess the efficacy of each drug in arresting preterm labor. Delivery was delayed for 25.8 days in patients treated with terbutaline and 13.0 days in patients treated with ritodrine. Patients treated with terbutaline gave birth to infants with a mean birthweight of 2 588 grams and 60% achieved a gestation of 36 weeks. Patients treated with ritodrine gave birth to infants with a mean birthweight of 2 392 grams and 39% achieved a gestation of 36 weeks. From this study it is evident that parturition was more effectively delayed in women treated with terbutaline than in a similar group of women treated with ritodrine.

D007752	Obstetric Labor, Premature	Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
