Products Description
Precise Physicochemical Fingerprint
High-quality sildenafil citrate adheres to extremely stringent physicochemical standards. Its internationally recognized CAS number is 139755-87-8, its molecular formula is C₂₈H₃₈N₆O₁₁S, and its molecular weight is accurate to 666.70. In appearance, top-grade pharmaceutical-grade raw material presents as a fine white or off-white crystalline powder, free of any visible impurities. Its melting point is stable between 187℃ and 189℃, and its density is approximately 1.445 g/cm³. This highly stable crystal structure not only ensures the chemical inertness of the active pharmaceutical ingredient during storage and transportation but also lays a solid foundation for dissolution and bioavailability during subsequent tablet preparation.
Highly Selective Pharmacological Mechanism
As a highly selective phosphodiesterase type 5 (PDE5) inhibitor, the core advantage of high-quality sildenafil lies in its "precise targeting" ability. It effectively inhibits the breakdown of cyclic guanosine monophosphate (cGMP) by PDE5, thereby significantly increasing cGMP levels in the corpus cavernosum tissue of the penis. Triggered by sexual stimulation, this mechanism promotes relaxation of the smooth muscle of the corpus cavernosum, resulting in a large influx of blood and a natural and firm erection. The high purity of the top-grade raw material (typically ≥99%) ensures extremely low cross-reactivity with other PDE isoenzymes in tissues such as cardiac and skeletal muscle, greatly enhancing the safety margin of the medication.
Superior Clinical and Formulation Advantages:
High-quality raw materials endow the final formulation with excellent pharmacokinetic performance. It is rapidly absorbed after oral administration, typically reaching peak plasma concentration within 30 to 120 minutes, with an average onset time of only about 27 minutes and a duration of action of approximately 4 hours. Furthermore, the high-quality raw material possesses strong process compatibility, perfectly adapting not only to traditional film-coated tablets but also meeting the development needs of novel dosage forms such as orally disintegrating tablets and oral disintegrating films, providing patients with more discreet and convenient dosing options.
In conclusion, high-quality sildenafil citrate API, with its well-defined physicochemical parameters, excellent selective inhibitory ability, and flexible formulation adaptability, has consistently maintained its leading position in the field of vasoactive drugs, continuously providing solid molecular protection for the healthy lives of patients worldwide.
