Used primarily in the management of mild to moderate hypertension due to its ability to lower blood pressure by depleting catecholamines and serotonin from nerve terminals in the sympathetic nervous system. It acts slowly and produces a gradual reduction in blood pressure, making it suitable for long-term control. Also investigated for its potential in treating certain psychiatric conditions due to its effects on central nervous system monoamines, though this use is limited. Its application has declined with the advent of newer antihypertensive agents with fewer side effects.
