Product Description
Sildenafil Mesylate
CAS: 139755-91-2
Assay: 99% min.
yzchz08@ycgmp.com
Molecular Formula: C22H30B6O4S. CH3SO3H
Molecular Weight: 570
Packing:foil bags,1kg net/foil bag, 5kg/drum.
Appearance: White or white crystalline powder, odorless, bitter astringent taste, soluble in water and ethanol
skype: live:yzchz08
Usage: pharmaceutical material, hormone. As a cyclic guanosine monophosphate (cGMP) specific phosphodiesterase type 5 (PDE5) selective inhibitor, penile smooth muscle relaxation allows rapid erection. Sildenafil is cheap, is the development and production of low-cost classes available kidney yang-like the perfect material for medicine and health products.
Categories: Active Pharmaceutical Ingredients; Miscellaneous Biochemicals; Sildenafil; Erectile Dysfunction.
Applications:
Although tadalafil work by inhibiting PDE5, tadalafil's pharmacologic distinction is its longer half-life (17.50 hours) -compared to sildenafil (4.0-5.0 hours) and vardenafil (4.0-5.0 hours) -resulting in longer duration of action, and so partly responsible for "The Weekend Pill" sobriquet. Furthermore, the longer half-life is the basis for current investigation of tadalafil's daily therapeutic use in relieving pulmonary arterial hypertension. Sildenafil is approved in several world regions as a thrice-daily therapy for pulmonary arterial hypertension.
