Methylergometrine, also known asmethylergonovine and sold under the brand nameMethergine, is amedication of theergoline andlysergamide groups which is used as anoxytocic inobstetrics and as anantimigraine agent in the treatment ofmigraine headaches. It reportedly producespsychedelic effects similar to those oflysergic acid diethylamide (LSD) at high doses.^[2]

Medical uses

[edit]

Obstetric use

[edit]

Methylergometrine is a smooth muscle constrictor that mostly acts on theuterus. It is most commonly used to prevent or control excessive bleeding following childbirth and spontaneous or elective abortion, and also to aid in expulsion of retained products of conception after a missed abortion (miscarriage in which all or part of the fetus remains in the uterus) and to help deliver the placenta after childbirth. It is available as tablets or injection (IM orIV) or in liquid form to be taken orally.^[3]^[4]^[5]

Migraine

[edit]

Methylergometrine is sometimes used for both prevention^[6] and acute treatment^[7] of migraine. It is anactive metabolite ofmethysergide.^[8] In the treatment ofcluster headaches, methylergometrine has been initiated at a dose of 0.2 mg/day, rapidly increased to 0.2 mg three times per day, and increased to a maximum of 0.4 mg three times per day.^[8]

Contraindications

[edit]

Methylergometrine is contraindicated in patients withhypertension andpre-eclampsia.^[3] It is also contraindicated inHIV positive patients takingprotease inhibitors,delavirdine, andefavirenz (which is also an agonist at the 5-HT_2A–mGlu2 receptor protomer and increases the chances of a patient experiencing hallucinations during methylergometrine therapy).^[9]

Side effects

[edit]

Adverse effects include:^[3]

Nausea, vomiting, and diarrhea
Dizziness
Pulmonary hypertension^{[citation needed]}
Coronary artery vasoconstriction
Severe systemic hypertension (especially in patients withpre-eclampsia)
Convulsions

In excessive doses, methylergometrine can also lead to cramping,respiratory depression and coma.^[3]

Interactions

[edit]

Methylergometrine likely interacts with drugs that inhibit the liver enzymeCYP3A4, such asazole antifungals,macrolide antibiotics and many HIV drugs. It can also increase constriction of blood vessels caused bysympathomimetic drugs and other ergot alkaloids.^[3]

Methylergometrine is anagonist orantagonist toserotonin,dopamine, andα-adrenergic receptors. Its specific binding and activation pattern on these receptors leads to a highly, if not completely, specific contraction of smooth uterus muscle via serotonin5-HT_2A receptors,^[19] while blood vessels are affected to a lesser extent compared to other ergot alkaloids.^[3] It has been found to interact with the serotonin5-HT_1A,5-HT_1B,5-HT_1E,5-HT_1F,5-HT_2A,5-HT_2B,5-HT_2C,5-HT_5A, and5-HT₇ receptors.^[11]^[12]^[16]^[10] Methylergometrine is an agonist of the serotonin 5-HT_2B receptor and may be linked tocardiac valvulopathy.^[20]

Pharmacokinetics

[edit]

Thebioavailability of methylergometrine is 60% viaoral administration and 78% byintramuscular injection.^[1] It ismetabolized in theliver, with extensivefirst-pass metabolism.^[1] Theelimination half-life of the drug is 3.4 hours.^[1] It iseliminated mainly via metabolism and thenexcreted.^[1]

Natural occurrence

[edit]

Previously thought to be an exclusivelysynthetic compound, it has been reported to occurnaturally inArgyreia nervosa (Hawaiian baby woodrose).^[21]^[22] The drug is on theWorld Health Organization's List of Essential Medicines.^[23]

Chemistry

[edit]

Methylergometrine, also known asd-lysergic acid 1-butanolamide, is aderivative of theergoline andlysergamide classes and is structurally related toergometrine (d-lysergic acid β-propanolamide) andlysergic acid diethylamide (LSD).

History

[edit]

Methylergometrine was first described in thescientific literature by 1945.^[24]^[25]

Society and culture

[edit]

Recreational use

[edit]

Methylergometrine is asynthetic analogue ofergometrine, apsychedelic alkaloid found inergot, and many species ofmorning glory. Methylergometrine is a member of theergoline family and chemically similar toLSD,ergine,ergometrine, andlysergic acid. According toJonathan Ott, methylergometrine produces LSD-likepsychedelic effects at doses of 2 mg and above.^[26] Clinical effectiveness of methylergometrine as a medication occurs around 200 μg, which is 10 times lower than the hallucinogenic threshold.^[26]
