Yohimbine HCL

Yohimbine common brand names are: Erex, Testomar, Yocon, Yohimar, Yohimbe. It is a stimulant with aphrodisiac and mild MAOI effects that primarily acts as an antagonist of α2 receptors. It is sometimes sold as prescription medicine in pure form for the treatment of xerostomia and sexual dysfunction. Yohimbine was explored as a remedy for type 2 diabetes in animal and human models carrying polymorphisms of the α2A-adrenergic receptor gene.

Yohimbine hydrochloride Description:

 

Yohimbine common brand names are: Erex, Testomar, Yocon, Yohimar, Yohimbe. It is a stimulant with aphrodisiac and mild MAOI effects that primarily acts as an antagonist of α2 receptors.  It is sometimes sold as prescription medicine in pure form for the treatment of xerostomia and sexual dysfunction. Yohimbine was explored as a remedy for type 2 diabetes in animal and human models carrying polymorphisms of the α2A-adrenergic receptor gene.

 

Yohimbine hydrochloride Applications:
1). Sexual dysfunction——–The NIH states that yohimbine hydrochloride is the standardized form of yohimbine that is available as a prescription medicine in the United States, and that it has been shown in human studies to be effective in the treatment of male erectile dysfunction. Yohimbine has been shown to be effective in the treatment of orgasmic dysfunction in men. Yohimbine has also been used to treat hypoactive sexual desire disorder (under active libido) in women.

 

2). Fat loss——–Yohimbine has shown to increase lipolysis in multiple studies.Administered prior to exercise, it boosts lipolysis and serum FFA levels both during and following exercise; blockade of adipocyte alpha-2 adrenoreceptors makes at least a modest contribution to this pro-lipolytic activity. Pre-exercise yohimbine administration has the potential to down-regulate the lipoprotein lipase activity of visceral adipocytes, increase lipolysis in refractory gynoid fat depots, and improve the impaired lipolytic response to exercise in the elderly

Safety Concerns:
Patients sensitive to rauwolfia alkaloids such as deserpidine, rauwolfia serpentina, or reserpine may also be sensitive to yohimbine.
Yohimbine readily penetrates the (CNS) and produces a complex pattern of responses in lower doses than those required to produce peripheral alpha-adrenergic blockade. These include, anti-diuresis, a general picture of central excitation including elevation of blood pressure and heart rate, increased motor activity, nervousness, irritability and tremor. Sweating, nausea and vomiting are common after parenteral administration of the drug. Also, dizziness, headache skin flushing reported when used orally.
Generally, this drug is not proposed for use in females and certainly must not be used during pregnancy.
