Empty the stomach by gastric lavage or emesis depending on the patient’s level of consciousness, and maintain adequate airway. For prevention of circulatory collapse, appropriate positioning of patient, fluids and, if necessary, vasopressor agents may be beneficial.
Drug Interactions
May reduce plasma concentration of ticlopidine. Enhanced serotonergic effect w/ MAOIs, linezolid.  May enhance the adverse effect of antipsychotic agents, metoclopramide. Enhanced vasoconstriction w/ beta-blockers. May diminish the vasodilatory effect of nitroglycerin.
Potentially Fatal: Increased plasma concentration, leading to ergotism, when used w/ potent CYP3A4 inhibitors including protease inhibitors (e.g. boceprevir, darunavir, ritonavir), azole antifungals (e.g. ketoconazole, itraconazole, voriconazole), and some macrolide antibiotics (e.g. erythromycin, clarithromycin, telithromycin).
Action
Description: Co-dergocrine mesylate is a mixture of hydrogenated derivatives of ergot alkaloids, including dihydroergocornine, dihydroergocristine, and dihydroergocryptine (dihydro-α-ergocryptine and dihydro-β-ergocryptine in 2:1 ratio). It was originally classed as a peripheral and cerebral vasodilator, but now considered as a metabolic enhancer. However, the exact mechanism of action by which it produces mental effects has not been determined.
Pharmacokinetics:
Absorption: Rapidly absorbed from the GI tract. Bioavailability: 25%. Time to peak plasma concentration: 1.5-3 hr.
Distribution: Plasma protein binding: 81%.
Metabolism: Undergoes extensive hepatic first-pass metabolism.
Excretion: Mainly via faeces and also in urine (approx 2 %). Elimination half-life: Biphasic: 1.5-2.5 hr (α phase); 13-15 hr (β phase).
