Description
Tastylia (Tadalafil) 20 mg
Tastylia 20 mg is a tadalafil product identified from the supplied name and strength. Tadalafil is a prescription phosphodiesterase type 5 (PDE5) inhibitor used for erectile dysfunction in adult men; in some regulated products it is also approved for benign prostatic hyperplasia and for men with both conditions. The product form in this listing is an oral strip, but the verified medicine ingredient is tadalafil.
Active Ingredient and Medicine Class
The active ingredient is tadalafil. It belongs to the PDE5 inhibitor class. This class helps increase blood flow in erectile tissue by enhancing the nitric oxide–cGMP pathway.
Established Medical Uses
Official prescribing information confirms tadalafil for the treatment of erectile dysfunction. Some approved products also include treatment of benign prostatic hyperplasia, and in certain labels both erectile dysfunction and BPH symptoms are listed. Tadalafil works only with sexual stimulation and is not indicated for use in children.
How It Works
Tadalafil inhibits PDE5, an enzyme that breaks down cyclic GMP. By slowing this breakdown, it supports smooth-muscle relaxation and blood flow in the penis during sexual stimulation, which can help achieve and maintain an erection.
Important Safety Information
Tadalafil is contraindicated with nitrates and with guanylate cyclase stimulators such as riociguat because of the risk of marked blood-pressure lowering. Prescribing information also warns about use in patients for whom sexual activity is not advisable because of cardiovascular disease. Caution is needed with alpha-blockers, antihypertensives, substantial alcohol intake, potent CYP3A4 inhibitors, renal impairment, hepatic impairment, and in patients at risk of priapism or sudden visual or hearing changes.
Possible Side Effects
Common adverse effects include headache, dyspepsia, back pain, nasal congestion, myalgia, dizziness, diarrhoea, and pain in the limbs. Important but less common serious reactions include prolonged erection, severe hypotension, vision or hearing loss, and hypersensitivity reactions such as Stevens-Johnson syndrome or exfoliative dermatitis.
Scientific Evidence
Peer-reviewed reviews and clinical analyses in PubMed report that tadalafil improves erectile function across a range of patients, with a long duration of action that can extend the therapeutic window. The evidence also supports its established safety profile when used within labelled restrictions, while confirming that headache, dyspepsia, back pain, and flushing are among the most frequent adverse effects.
