Objective: To assess the effect of sildenafil citrate treatment on visual field analysis (VFA) in patients using sildenafil citrate for erectile dysfunction.
Materials And Methods: In this prospective study on 18 male volunteers with erectile dysfunction, bilateral VFA was performed using the Humphrey 30-2 central standard threshold test. White-on-white (W/W) and blue-on-yellow (B/Y) protocols were used prior to treatment (baseline VFA) and after treatment (repeat VFA) with sildenafil citrate. W/W and B/Y baseline VFA and repeat VFA mean deviations (MD) were compared.
Results: The baseline MD for W/W and B/Y protocols were -1.34 +/- 1.8 and -2.59 +/- 2.1 dB, respectively, whereas the mean repeat MD for W/W and B/Y protocols were -1.79 +/- 2.21 and -2.83 +/- 3.31 dB, respectively. There was no statistically significant difference between W/W and B/Y baseline and repeat VFA with respect to MD (p > 0.05).
Conclusion: Sildenafil citrate causes no significant changes in Humphrey VFA in patients with erectile dysfunction.

The present work focuses on the production of sildenafil co-evaporates loaded emulgels as topical dosage forms for the treatment of premature ejaculation and erectile dysfunction. Topical administration of sildenafil citrate (SILD) co-evaporates is expected to improve the bioavailability profile of the drug and to avoid the severe side effects accompanying the traditional SILD dosage forms, especially for prohibited cardiovascular cases. Firstly, the solubility of SILD was improved via solid dispersion via co-evaporation technique using PEG-5KDa and PVP-K90 as hydrophilic carriers.

Orodispersible film (ODF) is one of the novel formulations that disintegrate rapidly in the mouth without the requisite for water compared to other conventional oral solid dosage formulations. This delivery system serves as a convenient mode of administration, especially in patients who have dysphagia and fluid restriction, being beneficial to pediatric, geriatric, and bedridden patients. A novel sildenafil ODF containing sildenafil citrate is formulated to be used in patients with erectile dysfunction (ED).

Article Synopsis
- Moringa and Sildenafil oleifera (MO) may protect against gastric ulcers caused by medication in rats.
- The study tested various groups of rats with one group receiving the ulcer-inducing drug indomethacin, and some receiving the protective effects of either Sildenafil, Moringa, or both beforehand.
- Results showed that Sildenafil and Moringa effectively reduced ulcer severity and inflammation markers, indicating their potential as gastroprotective agents.

Sildenafil is used to treat erectile dysfunction and pulmonary arterial hypertension but is often illicitly added to energy drinks and chocolates. This study introduces a lateral flow strip test using aptamers specific to sildenafil for detecting its illegal presence in food. The process involved using graphene oxide SELEX to identify high-affinity aptamers, which were then converted into molecular gate structures on mesoporous silica nanoparticles, creating a unique signaling system.

Background: Previous studies had shown that the neutrophils/lymphocytes (NLR) and platelets/lymphocytes (PLR) ratios could be used as markers of inflammatory load as well as prognostic factors in several medical conditions. The current study aimed to compare the effect of using daily tadalafil 5 mg/day versus daily sildenafil 25 mg/day in improving erectile function as well as their ability to reduce NLR and PLR.
Methods: One hundred and four participants were recruited.
