Sildenafil Citrate [Cas No. 171599-83-0] is a very powerful and selective PDE5 inhibitor which is mainly used to treat erectile dysfunction and pulmonary arterial hypertension [PAH]. Sildenafil Citrate has rapid onset of action, high safety and high efficacy which makes it a key component for oral formulations. It enhances the natural effect of nitric oxide [NO] by inhibiting cGMP specific phosphodiesterase type 5 [PDE5], an enzyme which is responsible for breaking cGMP. cGMP is a molecule which helps to smoothen the muscle relaxation and increases blood flow, thus by increasing cGMP level Sildenafil Citrate improve vascular relaxation and support good blood flow to the body tissues.

Handle in controlled pharmaceutical manufacturing areas
Follow GMP material handling procedures
Refer to Safety Data Sheet (SDS) for detailed safety guidance
This API is intended exclusively for pharmaceutical manufacturing and formulation use.
Sildenafil Citrate is a phosphodiesterase type-5 (PDE5) inhibitor that prevents the breakdown of cyclic guanosine monophosphate (cGMP) in smooth muscle cells. Elevated cGMP levels promote smooth muscle relaxation and vasodilation in the corpus cavernosum and pulmonary vasculature, enhancing blood flow. This mechanism supports its therapeutic use in erectile dysfunction and pulmonary arterial hypertension.
Handle in approved pharmaceutical manufacturing facilities
Avoid exposure without protective equipment
Prevent dust generation and inhalation
Follow GMP containment procedures
Dispose according to regulatory guidelines
Store in tightly closed containers
Protect from moisture and light
Maintain controlled room temperature
Keep in designated API storage areas
