Used primarily in the prevention of migraine and cluster headaches, this compound acts as a serotonin receptor agonist, particularly at 5-HT1 and 5-HT2 receptors. It helps reduce the frequency and severity of vascular headaches by modulating cerebral blood flow and neuronal activity. Due to the risk of fibrotic complications with long-term use, such as retroperitoneal or cardiac fibrosis, its use is generally limited to short-term or intermittent therapy when other treatments are ineffective. It is not intended for acute headache relief but rather for prophylactic management in chronic cases.
