A study in men with erectile dysfunction showed that Fildena 120mg sildenafil reduced their SBP significantly. The Fildena Double 200 drug reduced the patients' ED. The NTG alone had no effect on DBP. At a one-hour time point, sildenafil significantly reduced SBP. Despite these adverse effects, sildenafil did not result in any withdrawal from the study. In addition, sildenafil and nitroglycerin also significantly lowered their BP.
As a result, there are several generic versions of PDE5 inhibitors available. Sildenafil, the most commonly prescribed ED drug, is a relatively inexpensive option. Generic versions of both vardenafil and tadalafil are cheaper than brand-name medications. Interestingly enough, avanafil is not a generic drug and is the most expensive ED drug available.
