ergonovine
Very lowTechnical/specialist (medical)
Definition
Meaning
A synthetic alkaloid derived from ergot, used primarily as a medication to stop or prevent postpartum hemorrhage by contracting the uterus and as a diagnostic tool to provoke coronary artery spasm.
In medical contexts, it can also refer more generally to any ergot-derived medication used to induce smooth muscle contraction, particularly of blood vessels and the uterus. In lay terms, it is a powerful drug for controlling severe bleeding after childbirth.
Linguistics
Semantic Notes
Ergonovine is a hypernym for specific branded medications (e.g., Ergotrate). It is distinct from other ergot alkaloids like ergotamine, which are used for migraines. Its primary semantic field is obstetrics/pharmacology/cardiology.

FAQ
Frequently Asked Questions
No. While both are uterotonics (drugs that make the uterus contract), ergonovine is an ergot alkaloid, and Pitocin (oxytocin) is a pituitary hormone. They have different mechanisms and side effect profiles.
No. Ergonovine is not typically used for migraines. Its primary action is on the uterus and coronary arteries, whereas drugs like ergotamine and dihydroergotamine are specifically formulated for migraine treatment.
Ergonovine can provoke coronary artery spasm in a controlled setting (ergonovine challenge test). This helps diagnose variant (Prinzmetal's) angina, a condition caused by temporary artery narrowing rather than blockages.
Common side effects include nausea, vomiting, headache, increased blood pressure, and chest pain (due to its vasoconstrictive effects). It is used with caution under medical supervision.
