The Fildena pill is a drug that is used to treat patients with erectile dysfunction (ED). It is made up of sildenafil citrate, which belongs to the class of drugs called phosphodiesterase type 5 inhibitors. Sildenafil works by increasing blood flow to the penis, which improves erections.
PDE5 inhibitors are a class of oral medicines that act by inhibiting the action of phosphodiesterase 5 on cyclic guanosine monophosphate, or cGMP. This causes the body to produce nitric oxide, which helps relax smooth muscle tissue in the penis and increases blood flow to the penis.
Some of the common PDE5 inhibitors are sildenafil, tadalafil, and vardenafil. These medications are effective in treating erectile dysfunction and may also be used to treat premature ejaculation.
These medications are generally safe to take, although they can have some side effects if taken in high doses. Some of these effects are mild, while others can be severe. If you notice any of these side effects, call your doctor or seek emergency care right away.
Those with high blood pressure are not recommended to take PDE5 inhibitors, as they can cause a drop in arterial blood pressure. Additionally, if you have certain medical conditions, such as recent stroke, unstable angina or myocardial infarction, or if you have uncontrolled blood pressure, you should not take a PDE5 inhibitor.
Other medications that can help treat erectile dysfunction include the drugs Viagra and Cialis. These medications work by increasing blood flow to the penis, causing an erection when you're sexually aroused.
