Intramuscular 16-phenoxy PGE2 ester for pregnancy termination
Prostaglandins
|March 1, 1979
Summary
Sulprostone, a new prostaglandin E2 derivative, effectively induced pregnancy termination in women. This drug demonstrated high success rates for both medical interruptions and fetal demise cases, with manageable side effects.
Area of Science:
- Reproductive Medicine
- Pharmacology
- Obstetrics
Background:
- Pregnancy termination is sometimes medically necessary due to maternal health risks or fetal demise.
- Effective and safe pharmacological agents are crucial for managing pregnancy interruption.
Purpose of the Study:
- To evaluate the efficacy and safety of sulprostone, a novel prostaglandin E2 derivative, for pregnancy termination.
- To assess sulprostone's utility in both intact pregnancies with medical indications and cases of intrauterine fetal death.
Main Methods:
- Intramuscular administration of 500 micrograms of sulprostone to 48 women across three trimesters of pregnancy.
- Dosing regimen involved repeat doses every 4-6 hours for up to 24 hours, depending on the indication.
- Two groups were studied: intact pregnancies (n=21) and pregnancies with fetal death (n=27).
Main Results:
- High success rates were observed: 81% for intact pregnancies and 92.6% for fetal death cases.
- The mean induction interval was 12.9 hours.
- Side effects were generally mild, with over half experiencing only uterine colics; vomiting/diarrhea occurred infrequently (mean 1.4 episodes).
Conclusions:
- Sulprostone is an effective agent for inducing pregnancy termination.
- The drug exhibits a favorable safety profile, even in critically ill patients, with minimal serious complications.
- Sulprostone offers a viable and relatively safe option for pregnancy interruption.
