Mechanism and action
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. Klonopin: Clonazepam binds to the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance, hyperpolarising central nervous system neurons.
When Viagra Professional is preferred
Viagra Professional is intended for adult men with erectile dysfunction.
When Klonopin is preferred
Klonopin is approved in adults for the treatment of certain seizure types, including absence and atypical absence seizures, myoclonic and akinetic seizures, and as adjunctive therapy in Lennox-Gastaut syndrome.
