Guanabenz (pronounced GWAHN-a-benz, sold under the trade nameWytensin) is analpha agonist that is selective to thealpha-2 adrenergic receptor. Guanabenz is used as anantihypertensive drug used in the treatment of high blood pressure (hypertension).[1][2]

The most common side effects during guanabenz therapy aredizziness,drowsiness,dry mouth,headache andweakness.[3]

Guanabenz can make one drowsy or less alert, therefore driving or operating dangerous machinery is not recommended.

Research

[edit]

Guanabenz also has some anti-inflammatory properties in different pathological situations, including multiple sclerosis.[4]

Guanabenz was found in one study to exert an inhibitory effect by decreasing the abundance of the enzyme CH25H, a cholesterol hydroxylase linked to antiviral immunity. Therefore, it is suggested that the drug and similar compounds could be used to treat type I interferon-dependent pathologies and that the CH25H enzyme could be a therapeutic target to control these diseases,[5] including amyotrophic lateral sclerosis.
