Tadalafil is a drug used to treat erectile dysfunction. The drug helps to achieve and maintain an erection, which is necessary for sexual intercourse.
The action of tadalafil is based on blocking the enzyme phosphodiesterase type 5 (PDE-5). As a result, cyclic guanosine monophosphate (cGMP) accumulates in the cavernous body of the penis, which relaxes smooth muscles and increases blood flow to tissues.
A number of clinical studies have proven the high efficacy and good tolerability of tadalafil. At the same time, the drug has a number of contraindications and restrictions for use. It is necessary to consult a doctor before use.
It is important to note that the decision to prescribe the drug should be made only by a doctor after conducting the necessary examinations.
