2014, International Journal of Pharmacy and Pharmaceutical Sciences The aim of this study was to validate a high-performance liquid chromatographic (HPLC) method for analysis of sildenafil citrate in an extemporaneous preparation, according to ASEAN guideline for the validation of analytical procedure. Methods: The chromatographic condition used a C18 column with a mobile phase consisted of 50% 0.2 M ammonium acetate buffer pH 7.0 and 50% acetonitrile. The flow rate was performed at 1.0 mL/min, and UV detection was monitored at 245 nm. Results: It was shown that the retention time of sildenafil was about 8.80 min. The analytical method used was specific to sildenafil in the presence of other common excipients in the preparation. Nonthaburi: Bureau of Drug Control, Food and Drug Administration; 2004.
- Patients should avoid heavy meals before taking sildenafil solution.
- Use caution if combining with other blood pressure medications.

Linearity was assessed using a concentration range of 0.01 - 60.00 µg/mL, achieving a correlation coefficient of 0.9999. The method yielded a limit of detection (LOD) of 3.82 ng/mL and a limit of quantification (LOQ) of 11.57 ng/mL. Under forced degradation, 95.99% of sildenafil remained after treatment with acidic and basic hydrolysis, indicating good stability.

of Madrid, Spain to acquire the exclusive international patent rights related to a proprietary oral spray suspension formulation of sildenafil citrate (Sildenafil Oral Spray) for five million common shares. Aspargo acquired the exclusive U.S. patent rights covering Sildenafil Oral Spray from Farmalider, S.A. in January 2020. Aspargo’s Sildenafil Oral Spray is an oral liquid suspension of sildenafil citrate administered via a spray pump that dispenses 12.5 mg of sildenafil citrate sildenafil 12 5 mg per push of the pump (referred to as ASP-001) or via an individual single liquid unit dispensing 100 mg per unit (referred to as ASP-002). In May 2020, Aspargo announced the results of its pre-Investigational New Drug (pre-IND) meeting with the United States Food & Drug Administration (FDA), where the FDA addressed Aspargo’s questions and provided guidance on the Company’s Sildenafil Oral Spray for the treatment of erectile dysfunction (ED). The FDA was supportive of a single dose bioequivalent study comparing Aspargo’s Sildenafil Oral Spray, an oral liquid suspension formulation of sildenafil citrate, with VIAGRA® tablets as the basis for approval and deemed the 505(b)(2) regulatory pathway appropriate for the program. “The acquisition of global rights to Sildenafil Oral Spray represents a significant opportunity for Aspargo”, said Michael Demurjian, Aspargo’s Founder and Chief Executive Officer. “The erectile dysfunction market is one of the most expansive categories in the healthcare industry, as men continue to seek a more efficient and convenient solution to address their condition.
