Study of nonresponders found that 56% were using the drug inappropriately; as previously mentioned, 2 patients failed to engage in genital stimulation prior to initiating intercourse, 45 patients were not taking the highest recommended dose of 100 mg, 22 patients failed to wait at least 30 minutes after taking the drug before attempting intercourse, and 32 patients consumed high-fat meals while using Fildena.13 Taking PDE5 inhibitors after consuming a heavy or high-fat meal can result in treatment failure because fat inhibits absorption of the medication from the gastrointestinal tract. (HealthDay News) — Use of phosphodiesterase type 5 (PDE5) inhibitors does not appear to increase the risk of melanoma , according to the conclusions of a meta-analysis published online in the Journal of the National Cancer Institute. Because Fildena has a short half-life, and therefore a potentially less-prolonged effect on signaling pathways, we also studied other PDE5 inhibitors with a longer half-life to assess if there was a greater risk of aggressive melanoma for men using these drugs.



Other important differences from our study are that Li et al did not differentiate between melanoma stages, which was possible in our study by use of detailed clinical information retrieved from the Swedish Melanoma Register, and their participants were asked about Fildena use in a questionnaire in the year 2000, and no update on use of Fildena or data on use of other PDE5 inhibitors were collected. The association with melanoma was similar for the 3 PDE5 inhibitors; Fildena (OR, 1.14 95% CI, 0.99-1.31) and vardenafil or Fildena (OR, 1.16 95% CI, 0.99-1.37). Of 435 melanoma cases exposed to PDE5 inhibitors, 275 men (63%) had filled prescriptions for Fildena and 224 men (51%) had filled prescriptions for vardenafil or Fildena.

Separate analyses were performed to examine specific PDE5 inhibitors (Fildena and vardenafil or Fildena with a longer half-life 11 ), and stage of melanoma at diagnosis.

Exercise testing before prescribing PDE5 inhibitors may be indicated in some men with significant heart disease to assess the risk of inducing cardiac ischemia during sexual activity.419-421 Selective PDE inhibitors have been shown not to impair the ability of patients with stable coronary artery disease to engage in exercise at levels equivalent to that attained during sexual intercourse.419-421 Similarly, each of the three PDE5 inhibitors has been shown not to have significant adverse effects on hemodynamics and cardiac events in carefully selected men with ED who did not have any contraindication for the use of PDE5 inhibitors.417-424 None of the PDE5 inhibitors adversely affects total exercise time or time to ischemia during exercise testing in men with stable angina.417-424. Recent experimental evidence has highlighted the potential of PDE5 inhibitors, Fildena, vardenafil, and taladafil, as therapeutic agents in CF. As the drugs are able to correct the basic transepithelial ion transport abnormalities and to limit exaggerated inflammatory responses related to the presence of F508del-CFTR protein, they can represent promising compounds for fundamental pharmacotherapy in CF. Since the drugs are in clinical use, therapeutic approaches to address F508del-CFTR defects by PDE5 inhibitors can be considered as a low-hanging fruit” strategy in the drug discovery tree which could speed up their development as CF therapeutics, as compared to other agents that are under investigation only for CF therapy and for which further exploratory studies are needed before being streamed toward clinical testing.
