Tadalafil
Tadalafil is an oral medication primarily used to treat erectile dysfunction (ED) in men. It is most commonly known by the brand name Cialis. Tadalafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
When a man experiences ED, it means there is insufficient blood flow to the penis, making it difficult to achieve and sustain an erection. Tadalafil works by inhibiting the action of the enzyme PDE5, which is responsible for breaking down a substance called cGMP. By blocking PDE5, Tadalafil allows cGMP levels to increase, leading to improved blood flow to the penis when sexually aroused. This can help men achieve and maintain erections for a longer duration.
Tadalafil is available in different dosages and is typically taken on an as-needed basis, about 30 minutes to an hour before sexual activity. It should be used as prescribed by a healthcare provider. It is essential to note that Tadalafil does not lead to automatic erections; sexual stimulation is still necessary for it to be effective.
In addition to treating ED, Tadalafil is also prescribed to treat benign prostatic hyperplasia (BPH) and pulmonary arterial hypertension in some cases. As with any medication, potential side effects and drug interactions should be discussed with a healthcare professional before use.
