Description
Tadarise (Tadalafil) 80 mg
Tadarise is a brand name used for tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil is an established prescription medicine used for erectile dysfunction, and it is also used in some regions for other approved urological or vascular conditions depending on the product label. This description is based on verified tadalafil prescribing information and scientific literature.
Active Ingredient and Medicine Class
The verified active ingredient is tadalafil. It belongs to the PDE5 inhibitor class. Medicines in this class help increase blood flow in specific tissues by enhancing the effects of nitric oxide-mediated smooth muscle relaxation.
Established Medical Uses
Tadalafil is indicated for the treatment of erectile dysfunction. Official labels also include other uses for some tadalafil products, such as benign prostatic hyperplasia and, for certain branded formulations, pulmonary arterial hypertension, but these indications depend on the specific product and market authorisation. The user-supplied product description identifies erectile dysfunction as the intended use.
How It Works
Tadalafil inhibits PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). By preserving cGMP, it supports relaxation of smooth muscle and increases blood flow in the penis during sexual stimulation. Clinical reviews describe tadalafil as having a longer duration of action than some other PDE5 inhibitors.
Important Safety Information
Tadalafil is contraindicated with nitrates and with guanylate cyclase stimulators such as riociguat because of the risk of significant hypotension. Prescribing information also warns about use in patients with cardiovascular disease in whom sexual activity is inadvisable, and it notes caution with alpha-blockers, antihypertensives, potent CYP3A4 inhibitors, alcohol, and other PDE5 inhibitors. Serious warnings include prolonged erection/priapism, sudden vision loss, and sudden hearing loss.
Possible Side Effects
Common adverse effects reported with tadalafil include headache, dyspepsia, back pain, myalgia, nasal congestion, and flushing. Less common but important reactions include hypotension, priapism, visual disturbances, and hearing changes. Rare hypersensitivity reactions have also been reported.
Scientific Evidence
Peer-reviewed reviews and clinical analyses have found tadalafil effective for erectile dysfunction across a range of severities and causes, with a therapeutic window that may extend up to 36 hours. Review articles also describe headache and dyspepsia as among the most frequent adverse effects.
