Cialis 20 Mg

Description

CIALIS (TADALAFIL)

Cialis is most commonly used to treat erectile dysfunction and impotence, which is when a man struggles to maintain an erection or cannot get erect at all. It’s also sometimes prescribed for an enlarged prostate. Tadalafil is the active ingredient of Cialis. It improves blood flow to the penis so a man can get an erection for sexual activity. Depending on how your doctor prescribes the medication, you might take it as needed before sex or every day. If you take it as needed, the effects may last up to 36 hours.

Common use

Cialis is an effective, reversible, selective inhibitor of phosphodiesterase type 5 (PDE 5) specific to cyclic guanosine monophosphate (cGMP). When sexual stimulation causes the local release of nitric oxide, inhibition of PDE 5 by Cialis leads to an increase of cGMP levels in the cavernous body of the penis. It results in relaxation of arterial smooth muscles and blood flow to the tissues of the penis that causes erections. Cialis has no effect when sexual stimulation is absent. Cialis improves erection and lets achieve successful sexual intercourse. The drug acts for 36 hours. If sexual arousal is present the effect appears even after 16 minutes after taking the medication.

Mechanism of Action: Cialis works by inhibiting an enzyme called phosphodiesterase type 5 (PDE-5), which is responsible for breaking down a chemical called cGMP. cGMP is necessary for smooth muscle relaxation and increased blood flow to the penis, which leads to an erection when sexually stimulated.

Dosage and direction

The recommended dose of Cialis is 20 mg it should be taken at least 16 minutes before the sexual activity. The effect persists for 36 hours. Take Cialis once daily and do not exceed the recommended dose.

Precautions

It is preferable not to use Cialis with grapefruit juice, alcoholic beverages, or tobacco. If you smoke tobacco and take Cialis concomitantly this may lead to a condition called NAION (sudden optic nerve-related vision loss). Inform your doctor before taking Cialis if you have an abnormal penis, including a curved penis and birth defects of the penis, had coronary artery disease, arrhythmia, angina, heart attack or heart failure, hypo- or hypertension, bleeding, stomach ulcers, diabetes, hyperlipidemia (excess of lipids in the blood), sickle-cell anemia, liver or kidney failure in history.
