High-Content Vardenafil Raw Material Supply

Vardenafil 224789-15-5 is used to treat male erectile dysfunction. This product must exert its effect under conditions of sexual stimulation by inhibiting PDE5 enzyme activity, reducing the degradation of cyclic guanosine monophosphate (cGMP), relaxing the smooth muscle of the penile corpus cavernosum, dilating cavernous blood vessels, and increasing local blood flow to help obtain and maintain an erection of sufficient hardness. This raw material has high selectivity for PDE5, has smaller effects on ocular PDE6, and has a relatively lower incidence of visual adverse reactions. The recommended starting dose for adult oral administration is 10mg, once daily, taken 25 to 60 minutes before sexual activity. According to efficacy and tolerability, the dose can be adjusted to 5mg or 20mg. The maximum recommended dose is 20mg per day.

The appearance of Vardenafil is a white or off-white crystalline powder. Under sexual stimulation, this product can inhibit PDE5 enzyme activity, reduce cyclic guanosine monophosphate degradation, relax penile corpus cavernosum smooth muscle, dilate blood vessels, increase local blood flow, and help improve male erectile dysfunction. This product has high selectivity, minimal effects on ocular-related enzymes, and relatively fewer visual adverse reactions. The raw material has high purity and strict impurity control, and a COA quality inspection report can be provided for each batch with stable quality. It can be used for tablet formulation production, pharmaceutical scientific research, reference standard testing, generic drug R&D, and API import and export business. The raw material is sealed and stored in a cool, dry, and light-protected environment, packaged in fiber drums or aluminum foil vacuum bags, and supports supply for both domestic and foreign orders.

This drug is a phosphodiesterase type 5 (PDE5) inhibitor. Oral administration of this drug can effectively improve erection quality and duration, increasing the sexual success rate of male patients with erectile dysfunction. The initiation and maintenance of penile erection are related to the relaxation of corpus cavernosum smooth muscle cells, and cyclic guanosine monophosphate (cGMP) is the mediator causing the relaxation of corpus cavernosum smooth muscle cells. This drug prevents cGMP breakdown by inhibiting phosphodiesterase type 5, thereby causing cGMP accumulation, corpus cavernosum smooth muscle relaxation, and penile erection. Compared with phosphodiesterase isoenzymes 1, 2, 3, 4, and 6, this drug has very high selectivity for phosphodiesterase type 5. Data show that its selectivity and inhibitory effect on phosphodiesterase type 5 are superior to those of other phosphodiesterase type 5 inhibitors, suggesting that this selectivity may make the cardiovascular and visual adverse reactions of this drug less than those of other phosphodiesterase type 5 inhibitors.
