Sildenafil/Sildenafil Citrate is one of the PDE5 (short for phosphodiesterase type-5) inhibitor drugs used in the treatment of erectile dysfunction in patients. Erectile dysfunction (ED) is the condition where males have great difficulty in exhibiting the erectile response and also have difficulty in maintaining an erection due to a number of factors. This difficulty is not associated with lack of arousal; the males with ED have difficulty in having erections even with ample sexual stimulation and arousal. Erectile dysfunction is due to physiological limitations due to age or damages done by diseases or poor lifestyle habits.
The active ingredient Fildena 100mg is only one of the 3 PDE5 inhibitors available for ED patients in the market. The other PDE5 inhibitors are Tadalafil and Vardenafil, which are drugs as equally effective as Sildenafil Citrate. These PDE5 inhibitors have various uses and they include:
- Erectile dysfunction treatment. This is the most common use of the PDE5 inhibitors, although their use is not only limited to improving erectile function in patients.
- Benign Prostatic Hyperplasia (BPH). BPH symptom management is one of the main uses of PDE5 inhibitors like Sildenafil as the product is effective in giving relief in patients having difficulty urinating or those with urinary retention as a result of prostate enlargement.
- Pulmonary Arterial Hypertension (PAH). Aside from ED, one of the indications for PDE5 inhibitors is for the condition PAH, since one of the effects of PDE5 inhibitors is lowering blood pressure.
- Angina Pectoris. The actual indication of Sildenafil during its discovery is for the treatment of angina, although it is not as effective as the researchers thought it would be. It gave erectile side effects, though, which led to its development as a treatment for erectile dysfunction.
