Tadact 20 mg contains Tadalafil as its active ingredient, and its primary function is to treat erectile dysfunction (ED) in men. It belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation, thereby helping men achieve and maintain an erection.

However, Tadact 20 mg is not indicated for or proven to directly improve sexual desire (libido) in men. Its main purpose is to facilitate erectile function by enhancing the natural erectile response to sexual stimulation. Here are some key points about Tadact 20 mg:

Mechanism of Action: Tadalafil in Tadact 20 mg inhibits PDE5, which leads to increased levels of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. This results in smooth muscle relaxation and increased blood flow to the penis, which helps in achieving and maintaining an erection.

Dosage: The recommended dosage of Tadact 20 mg is usually one tablet taken orally with water, approximately 30 minutes to 1 hour before anticipated sexual activity. It is important to follow the dosage instructions provided by your healthcare provider or as indicated on the medication packaging.

Effectiveness: Clinical studies have shown that Tadalafil, the active ingredient in Tadact 20 mg, is effective in treating ED in men. It typically has a longer duration of action compared to some other ED medications, lasting up to 36 hours.

Safety Considerations: Tadact 20 mg is generally safe when used as directed. Common side effects may include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. Serious side effects are rare but should be promptly reported to a healthcare provider if experienced.
