Comparative StudyA prostaglandin analogue (ONO-802) in treatment of missed abortion, intrauterine fetal death and hydatiform mole: a dose-finding trial.
Forty-eight patients affected with missed abortion, intrauterine fetal death and hydatiform mole were treated with vaginal suppositories containing 1 mg of 16,16-dimethyl-trans-delta 2-PGE1 methyl ester (ONO-802). The patients were divided into two treatment groups. The first, Group A, was given one vaginal suppository every 3 h to a maximum of five suppositories. ⋯ In Group B the maximum number of suppositories was reduced to three. The product of conception was expelled in 100% of cases and the average duration of treatment was similar to that for the first group. Although side-effects were mild in both groups, they were reduced in the patients of Group B.

In 16 anesthetized pigs the cardiovascular effects of prostaglandin E1 and methylprednisolone (MPS) during E. coli sepsis were studied. Gated blood pool scans and hemodynamic studies were simultaneously performed. A control group, group I (n = 4), received volume loading alone; groups II, III, and IV received (each n = 4) volume loading after intravenous administration of MPS, prostaglandin E1, and both MPS and prostaglandin E1, respectively. ⋯ The present study indicates that in a porcine model of E. coli septic shock with acute pulmonary hypertension, prostaglandin E1 and MPS treatment decrease pulmonary vascular resistance but also systemic vascular resistance. Prior to and during volume loading right ventricular ejection fraction increased in the prostaglandin E1 group. However, neither prostaglandin E1 nor MPS improved right ventricular performance and forward flow during volume loading.

Prostaglandin E1 (PGE1) was incorporated into soybean oil microspheres 0.2 micron in diameter, using lecithin as surfactant. The pharmacological effects of this new galenic form of PGE1 (lipo PGE1) was evaluated in experimental peripheral arterial occlusive disease in rats and in an ex vivo antithrombosis test in rats. ⋯ Total radioisotope activity of 3H-PGE1 in lipid microspheres in blood was higher and persisted longer than that of PGE1 in rats. These results suggested that the favourable features of lipo PGE1 depended on protection against inactivation in the lung and its targeting effect to tissues injured by arterial occlusion.

Randomized Controlled Trial Comparative Study Clinical TrialThe use of 16,16-dimethyl-trans delta 2 prostaglandin E1 methyl ester (gemeprost) vaginal pessaries for the termination of pregnancy in the early second trimester. A comparison with extra-amniotic prostaglandin E2.
The use of gemeprost pessaries has been compared in an open randomized trial with the extra-amniotic infusion of prostaglandin E2 (PGE2) for the termination of pregnancy between 12 and 16 weeks gestation. The success rates were 77% and 79% for the pessary and infusion group respectively, and these rates were unaffected by parity. ⋯ Side-effects, experienced both during treatment and during the 6 weeks after abortion, were similar in both groups. Gemeprost vaginal pessaries are an effective alternative to the extra-amniotic infusion of PGE2 for the termination of pregnancy in the early second trimester.

Clinical TrialControlled study of 16,16-dimethyl-trans-delta 2 prostaglandin E1 methyl ester vaginal pessaries prior to suction termination of first trimester pregnancies.
A pessary containing the prostaglandin analogue, 16,16-dimethyl-trans-delta 2 prostaglandin E1 methyl ester (Cervagem) was inserted into the vagina of primigravid women 2 h before suction termination of pregnancy. The cervix was softer, easier to dilate and more widely dilated at the start of the procedure than in a control group of women who received placebo pessaries containing the vehicle alone. ⋯ The incidence of pre- and post-operative abdominal cramps was increased in the Cervagem-treated group. No gastrointestinal side-effects were noted.
