Key differences
Xanax belongs to Anti-anxiety Medications while Viagra Professional belongs to Erectile Dysfunction (ED). Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Xanax: Alprazolam binds to the benzodiazepine site of the GABA-A receptor and allosterically enhances GABA-mediated chloride conductance, hyperpolarising central nervous system neurons. Viagra Professional: Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood inflow.
When Xanax is preferred
Xanax is approved in adults for the short-term management of generalised anxiety disorder and panic disorder with or without agoraphobia.
When Viagra Professional is preferred
Viagra Professional is intended for adult men with erectile dysfunction.
