Vidalista 20 mg: All You Need to Know from Wikipedia

"Vidalista 20 mg" contains tadalafil as its active ingredient.

1. Mechanism of action

- Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is an enzyme found in the smooth muscle cells of the corpus cavernosum in the penis. By inhibiting PDE5, tadalafil increases the levels of cyclic guanosine monophosphate (cGMP), which leads to relaxation of the smooth muscles in the penis, allowing increased blood flow into the corpus cavernosum during sexual stimulation, thus facilitating an erection.

2. Medical uses

- It is primarily used to treat erectile dysfunction (ED) in men.

- In some cases, under medical supervision, it may also be considered for the treatment of symptoms of benign prostatic hyperplasia (BPH), as it can help relax the smooth muscles in the prostate and bladder neck, improving urinary flow.

3. Precautions and side effects

- Precautions:

- It should not be used in patients taking nitrates (such as nitroglycerin) because the combination can cause a dangerous drop in blood pressure.

- People with certain heart conditions, liver or kidney problems may require dose adjustments or close medical monitoring.

- Side effects:

- Common side effects may include headache, flushing, indigestion, nasal congestion, back pain, and muscle aches. In rare cases, it may cause more serious side effects such as priapism (a prolonged and painful erection), sudden vision or hearing loss.
