Tadalafil 4 pills 20 mg is a long-acting medication that is effectively used to treat male sexual dysfunction (impotence or erectile dysfunction).
Mechanism of action
When a man becomes aroused, a chemical called nitric oxide (NO) is released into the penis. This chemical is important for the production of cyclic guanosine monophosphate (cGMP), which constricts and dilates the blood vessels in the body. The higher the amount of cGMP produced, the easier blood flows to certain parts of the body, including the penis. However, phosphodiesterase type 5 (PDE5) is the enzyme responsible for causing low cGMP production.
Tadalafil belongs to a group of medicines called phosphodiesterase inhibitors and works by reducing the activity of the PDE5 enzyme, which is responsible for the production of cGMP. This means that Tadalafil increases the production of cGMP and more blood flows to the penis, making it harder to get an erection.
Usage recommendations
Tadalafil is taken orally with plenty of water (do not chew it or take it with alcohol). The recommended dose of the drug is 20 mg (1 tablet) within 24 hours. This should be taken 30-45 minutes before planned sexual activity to get the most benefit from the drug. The effects of Tadalafil last up to 36 hours.
Negative effects
Some of the side effects caused by the use of Tadalafil include headache, dyspepsia, back pain, facial flushing or redness, nasal congestion, or mild nausea.
