Uses
Guanabenzum is an alpha-2 adrenergic agonist used to treat hypertension.
For management of High blood pressure
How Guanabenzum works
Guanabenzum's antihypertensive effect is thought to be due to central alpha-adrenergic stimulation, which results in a decreased sympathetic outflow to the heart, kidneys, and peripheral vasculature in addition to a decreased systolic and diastolic blood pressure and a slight slowing of pulse rate. Chronic administration of guanabenz also causes a decrease in peripheral vascular resistance.
Toxicity
Excessive contraction of the pupils, irritability, low blood pressure, sleepiness, slow heartbeat, sluggishness
Guanabenzum Alcohol interaction
[Moderate]
Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation.
Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.
Caution and close monitoring for development of hypotension is advised during coadministration of these agents.
Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs.
Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
