Like its predecessor Viagra, Cialis is used to treat erectile dysfunction in men. One of the more embarrassing side effects of post-cycle-therapy is the decreased libido caused by the sudden absence of exaggerated testosterone levels in the body, often leading to ED. If you can’t get it up after your cycle, get the pill.
Cialis (Tadalafil Citrate): A Profile
Cialis, the brand name for tadalafil citrate, is a widely prescribed medication used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). Known for its long-lasting effects, Cialis has earned the nickname “the weekend pill,” as a single dose can remain effective for up to 36 hours.
Cialis works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of blood vessels. By blocking PDE5, Cialis enhances the effects of nitric oxide, leading to increased cGMP levels, relaxation of blood vessels, and improved blood flow to specific areas of the body, such as the penis. This mechanism enables men with ED to achieve and maintain an erection when sexually aroused.
In addition to ED, Cialis is approved for managing BPH symptoms, such as urinary urgency or difficulty urinating, by relaxing smooth muscles in the bladder and prostate. For PAH, it improves blood flow in the lungs, reducing strain on the heart.
Common side effects of Cialis include headache, indigestion, back pain, muscle aches, nasal congestion, and facial flushing. These effects are generally mild and temporary. Cialis is available in various doses, allowing flexibility based on individual needs and conditions.
With its prolonged duration of action and versatility in treating multiple conditions, Cialis has become a trusted and convenient solution for millions worldwide.
