Chemical Structure of Sildenafil Citrate

The chemical structure of sildenafil citrate comprises a pyrimidine ring fused with a pyrazolopyrimidinone core. This compound, classified as a phosphodiesterase type 5 (PDE5) inhibitor, enhances erectile function. Its molecular formula is C22H30N6O4S, with a molar mass of 474.58 g/mol. The structure supports the selective inhibition of the PDE5 enzyme, vital for cyclic guanosine monophosphate (cGMP) regulation in the corpus cavernosum. Its specific conformation ensures high efficacy and a predictable pharmacokinetic profile.

Off-Label Uses and Potential Benefits

Viagra Sublingual, typically used for erectile dysfunction, has off-label applications. Clinical trials explore its role in treating pulmonary arterial hypertension. Sildenafil 100mg demonstrates promise in managing Raynaud’s phenomenon and chronic thromboembolic pulmonary hypertension. Investigations also assess its benefits in female sexual arousal disorder. Such uses exploit sildenafil’s vasodilatory effects. Research into these areas continues, aiming to expand therapeutic indications.
