High-Quality Sildenafil Mesylate Raw Material Powder

Sildenafil Mesylate is a selective phosphodiesterase type 5 (PDE5) inhibitor that must exert its efficacy under sexual stimulation. By inhibiting type 5 phosphodiesterase, it reduces the breakdown of cGMP in the body, relaxing penile corpus cavernosum smooth muscle, dilating blood vessels, and increasing corpus cavernosum blood flow, helping to improve male erectile dysfunction. Its water solubility is superior to that of sildenafil citrate, making it more suitable for research on certain special dosage form formulations. The product itself does not produce sexual desire and will not take effect without sexual stimulation, merely improving the physiological engorgement process of erection. High-fat meals delay absorption, so taking it on an empty stomach is recommended. Serving as an active pharmaceutical ingredient (API) for formulation research and development, it is used to prepare oral tablets for research related to male erectile dysfunction.

Sildenafil Mesylate is a white or off-white crystalline powder, belonging to the selective phosphodiesterase type 5 (PDE5) inhibitor API raw materials. Its water solubility is superior to that of sildenafil citrate, making it suitable for special dosage form formulation R&D. The raw material has high purity and strictly controlled impurities, and a COA quality inspection report can be issued for each batch with stable quality. Under sexual stimulation, it inhibits PDE5 enzyme, reduces cGMP degradation, relaxes penile corpus cavernosum smooth muscle, dilates blood vessels, increases local blood flow, and helps improve male erectile dysfunction. The product itself does not stimulate sexual desire and cannot take effect without sexual stimulation. The raw material needs to be protected from light, sealed, and stored in a cool and dry environment. Regular packaging uses 25kg fiber drums, and small samples use aluminum foil vacuum bags. It can be used for formulation R&D, pharmacological research, reference standard testing, and API import and export business. It is used as an API solely for scientific research and formulation development, subject to compliant use.

1.Sildenafil Mesylate belongs to the selective phosphodiesterase type 5 (PDE5) inhibitors, mostly used for the formulation R&D related to male erectile dysfunction.

2.Under sexual stimulation conditions, it inhibits PDE5 enzyme activity and reduces the degradation of cyclic guanosine monophosphate (cGMP) in the body.

3.Relaxes smooth muscle of the penile corpus cavernosum, dilates cavernous blood vessels, and enhances local blood perfusion volume.

4.Helps users obtain and maintain an erection of sufficient hardness, improving erectile dysfunction issues.

5.The raw material has good water solubility, which, compared to Sildenafil Citrate, is suitable for formulation development trials of special dosage forms.

6.This product cannot independently stimulate sexual desire; it can take effect only when sexual stimulation exists, merely improving the physiological process of erectile engorgement.

1.Drug formulation R&D, used for formulation screening and process trials of Sildenafil Mesylate tablets.

2.Pharmaceutical scientific research experiments, serving as raw materials to carry out in vitro and in vivo studies on pharmacology and toxicology.

3.Laboratory reference standards, used for raw material assay and impurity testing analysis.

4.API import and export, supplying domestic and overseas scientific research institutions and R&D enterprises.

5.Innovative dosage form development, used for formulation research of soluble oral preparations.

6.Generic drug stability study trials, investigating the long-term and accelerated stability of the raw material.

1.Identification: Infrared spectroscopy (IR) and HPLC retention time comparison method are used for qualitative confirmation.
2.Assay Determination: High-Performance Liquid Chromatography (HPLC) external standard method is used to measure active ingredient content.
3.Related Substances: An HPLC method is used to detect individual impurities as well as total impurities, controlling impurity limits.
4.Water Content: The Karl Fischer method is used to determine sample water content.
5.Heavy metals and residual solvents are tested using pharmacopoeial methods, and all indicators meet standards.

1.Samples adopt sealed packaging using thickened aluminum foil vacuum bags to isolate water vapor and oxygen, guaranteeing stable performance of small samples.
2.The raw material in the aluminum foil bag undergoes vacuum treatment with flexible specifications, facilitating laboratory testing for customers.
3.Bulk goods of 25kg select fiber drum packaging, with double-layer PE lining bags inside the drum and built-in desiccant for moisture-proof storage.
4.Foreign trade orders can choose sea freight or air freight according to customer needs, with transportation plans flexibly negotiated.
5.Complete export customs declaration documents can be provided to assist customers in preparing documents and aiding overseas customs clearance processes.
6.Product verification is performed well before shipment, synchronizing cargo bill of lading information to facilitate customers in tracking shipment conditions.
