Ergotamine normalizes the tone of dilated extracranial arteries. Caffeine accelerates and increases absorption of ergotamine in the intestine. Indications for use. Acute attacks of migraine and similar headaches of vascular genesis.
After oral administration, approximately 62% of ergotamine is absorbed in the GI tract . Maximum plasma concentrations are reached 2 hours after oral administration. Binding to plasma proteins is 98%. Ergotamine is metabolized in the liver to form pharmacologically active metabolites. Ergotamine is excreted mainly with bile both unchanged and as metabolites. Excretion is biphasic, with half-lives of 2.7 hours and 21 hours for I and II phases, respectively.
After oral administration caffeine is absorbed quickly and almost completely. Binding with plasma proteins is 35%. Caffeine is almost completely metabolized in the body. Metabolites are excreted mainly with urine. The elimination half-life is about 3.5 hours.
