Cialis is a widely used oral medication that contains tadalafil as its active ingredient. It is primarily prescribed for the treatment of erectile dysfunction in adult men, a condition where a man finds it difficult to achieve or maintain an erection suitable for sexual activit

Mechanism of Action
Tadalafil, the active compound in Cialis, works by improving blood flow to specific areas of the body. In the case of erectile dysfunction, it enhances blood flow to the penis during sexual stimulation. This is achieved by inhibiting an enzyme called phosphodiesterase type five. During sexual arousal, the body naturally releases nitric oxide in the penile tissues, which increases levels of a chemical called cyclic guanosine monophosphate. This chemical relaxes smooth muscles in the blood vessels, allowing more blood to flow in and cause an erection.

Phosphodiesterase type five breaks down this chemical, which can end the erection. By blocking this enzyme, tadalafil helps maintain higher levels of cyclic guanosine monophosphate, supporting a sustained erection when sexual stimulation is present. Its longer half-life allows it to remain effective in the body for over a day, making it unique among similar medications.

y. Cialis is also approved for the treatment of benign prostatic hyperplasia, which involves an enlarged prostate and urinary symptoms. One of the main advantages of Cialis is its long duration of action, which can last up to thirty-six hours, allowing for greater flexibility and spontaneity in intimate moments.

Uses
Cialis is used for:

• Treating erectile dysfunction in adult men

• Managing the symptoms of benign prostatic hyperplasia, such as difficulty urinating or frequent need to urinate

• In some cases, it may also be used for treating pulmonary arterial hypertension under a different brand and dosage

Adverse Effects
While Cialis is generally well tolerated, it may cause side effects in some individuals. Common side effects include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion. These effects are usually mild and temporary.

Less common but serious side effects may include chest pain, sudden vision or hearing loss, allergic reactions, or a prolonged erection lasting more than four hours. These symptoms require immediate medical attention.
