Tadalafil relaxes muscles of the blood vessels and increases blood flow
to particular areas of the body.Tadalafil under the name of Cialis is
used to treat erectile dysfunction (impotence) and symptoms of benign
prostatic hypertrophy (enlarged prostate). Another brand of tadalafil is
Adcirca, which is used to treat pulmonary arterial hypertension and
improve exercise capacity in men and women.
Application
Tadalafil (Cialis) is used to treat erectile dysfunction (ED, impotence;
inability to get or keep an erection), and the symptoms of benign
prostatic hyperplasia (BPH; an enlarged prostate) which include
difficulty urinating (hesitation, dribbling, weak stream, and incomplete
bladder emptying), painful urination, and urinary frequency and urgency
in adult men. Tadalafil (Adcirca) is used to improve the ability to
exercise in people with pulmonary arterial hypertension (PAH; high blood
pressure in the vessels carrying blood to the lungs, causing shortness
of breath, dizziness, and tiredness). Tadalafil is in a class of
medications called phosphodiesterase (PDE) inhibitors. It works to treat
erectile dysfunction by increasing blood flow to the penis during
sexual stimulation. This increased blood flow can cause an erection.
Tadalafil treats PAH by relaxing the blood vessels in the lungs to allow
blood to flow more easily.
Dosage
For most individuals, the recommended starting dose of tadalafil is 10
mg per day taken before sexual activity (tadalafil for use as needed).
Depending on the adequacy of the response or side effects, the dose may
be increased to 20 mg or decreased to 5 mg a day. The effect of
tadalafil may last up to 36 hours. Individuals who are taking
medications that increase the blood levels of tadalafil should not
exceed a total dose of 10 mg in 72 hours (See drug interactions). For
once daily use without regard to sexual activity the recommended dose is
2.5 to 5 mg daily. Tadalafil should not be taken more than once daily.
The recommended dose for BPH, or BPH and ED is 5 mg daily taken about
the same time each day. Tadalafil may be taken with or without food
since food does not affect its absorption from the intestine.
