Erectile dysfunction (ED) is more frequent among end-stage renal failure patients than the normal population. Sildenafil citrate has been successfully used for the symptomatic treatment of erectile dysfunction. The aim of this study was to determine the efficacy and safety of sildenafil citrate in the treatment of ED in patients on hemodialysis. Fifty-five hemodialysis patients above 18 years suffering from ED with steady sexual partners were included in the study. The first five and fifteenth questions of the International Index of Erectile Function were employed to evaluate ED in the patient group. A Single 50-mg sildenafil citrate tablet was prescribed for each patient. The patients were encouraged to take it on the day after hemodialysis and 1 hour before sexual intercourse. The erectile function of the patients after the treatment was re-evaluated in the same manner by International Index of Erectile Function. The ages of the patients ranged between 30 and 73 years (mean 50.6 +/- 10.9). The overall response rate was 74.5% (38/51). Side effects were nausea (n = 2), palpitation (n = 2), flushing (n = 1), and angina (n = 1). Sildenafil citrate (50 mg) was observed to be safe and effective for treatment of hemodialysis patients with careful evaluation and proper patient selection.

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.

Background And Aims: Systemic sclerosis (SSc) is an autoimmune connective disease characterised by excessive extracellular matrix deposition and widespread skin and internal organ fibrosis including various cardiac manifestations. Heart involvement is one of the leading causes of death among patients with SSc. In this study, we aimed to assess the effect of various vasodilator treatments.
