Vidalista 20 mg: What Wikipedia Reveals

"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 blood vessels in the penis. By inhibiting PDE5, tadalafil increases the levels of cyclic guanosine monophosphate (cGMP). This leads to relaxation of the smooth muscles in the penile arteries and subsequent increased blood flow into the penis, which helps in achieving and maintaining an erection during sexual stimulation.

2. Usage and indications

- It is primarily used for the treatment of erectile dysfunction (ED) in men. It can also be used in the treatment of pulmonary arterial hypertension in some cases, although the dosages may vary for different medical conditions.

3. Side effects

- Common side effects may include headache, flushing (redness and warmth of the skin), indigestion, back pain, muscle aches, and nasal congestion. In rare cases, it may cause more serious side effects such as sudden vision loss or hearing loss, although these are extremely uncommon.

- It is important to note that Wikipedia can be a good starting point for general information, but for medical advice and accurate diagnosis, one should consult a healthcare professional. Also, the use of Vidalista should be under the proper guidance of a doctor, especially considering potential drug - drug interactions and contraindications.
