Item does not contain fulltext, Ergotism is a toxic condition resulting from overexposure to the ergot compounds produced by various fungi of the genus Claviceps. Traditionally, such exposure was due to ingestion of infected grains, but long-term or excessive use of medications containing ergot derivatives or drug-drug interactions between these medications can result in ergotism. Ergotamine, typically used to treat migraine, has less than 5% bioavailability due to extensive first-pass metabolism by cytochrome P450 3A4 (CYP3A4). Concurrent intake of ergotamine and strong CYP3A4 inhibitors, such as the HIV protease inhibitors (PIs), can lead to clinical ergotism. A total of 13 cases of clinical ergotism in HIV-infected patients has been published since 1997 (most recently reviewed by Frohlich et al).
