Description
Tastylia (Tadalafil) 40 mg
Tastylia 40 mg is a tadalafil medicine. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor used for erectile dysfunction. It is intended to support erectile response in the presence of sexual stimulation.
Active Ingredient and Medicine Class
The verified active ingredient is tadalafil, a selective PDE5 inhibitor. This class blocks PDE5, an enzyme involved in breaking down cyclic GMP, a messenger that helps relax smooth muscle and increase blood flow in erectile tissue.
Established Medical Uses
Regulatory prescribing information for tadalafil tablets supports use in erectile dysfunction. Some tadalafil products are also approved for benign prostatic hyperplasia and pulmonary arterial hypertension, but those uses depend on the specific product and label. For this product identification, the verified and relevant use is erectile dysfunction.
How It Works
Tadalafil enhances the natural nitric oxide–cGMP pathway in penile tissue. By inhibiting PDE5, it helps preserve cGMP levels, which promotes smooth muscle relaxation and improved blood flow during sexual stimulation. It does not create an erection without sexual stimulation.
Important Safety Information
Tadalafil must not be used with nitrates because the combination can cause a marked fall in blood pressure. Important cautions also apply with alpha-blockers, antihypertensive medicines, strong CYP3A4 inhibitors, and substantial alcohol intake. Prescribing information also warns about hypersensitivity reactions, non-arteritic anterior ischemic optic neuropathy with sudden vision loss, and prolonged erection or priapism.
Possible Side Effects
Common adverse effects reported with tadalafil include headache, dyspepsia, back pain, nasal congestion, flushing, and myalgia. Less common but serious reactions may include severe allergic reactions, sudden vision or hearing changes, and priapism.
Scientific Evidence
Clinical reviews and meta-analyses show that tadalafil improves erectile function in men with erectile dysfunction, including on-demand and daily regimens. Published reviews also report a long duration of action, with some studies describing efficacy lasting up to about 36 hours, although side effects such as headache and dyspepsia remain common.
