Guanabenz
Guanabenz (pronounced GWAHN-a-benz, sold under the trade name Wytensin) is an alpha agonist that is selective to the alpha-2 adrenergic receptor. Guanabenz is used as an antihypertensive drug, i.e. to treat high blood pressure (hypertension).[1][2]

The most common side effects during guanabenz therapy are dizziness, drowsiness, dry mouth, headache and weakness.[3]
Guanabenz can make one drowsy or less alert, therefore driving or operating dangerous machinery is not recommended.
Other possible uses
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.
