Fildena Professional is a branded medication that contains sildenafil as its active ingredient. Sildenafil belongs to the class of phosphodiesterase-5 (PDE5) inhibitors and is used to treat erectile dysfunction (ED). The product is supplied as a 100 mg oral pill and is available by prescription in Hong Kong under the regulation of the Hong Kong Department of Health.
Sildenafil blocks the enzyme phosphodiesterase-5, which normally breaks down cyclic guanosine monophosphate (cGMP) in the penile tissue. By inhibiting PDE5, sildenafil allows cGMP to accumulate, leading to smooth-muscle relaxation and increased blood flow to the corpora cavernosa. This physiological response facilitates an erection when sexual stimulation is present. The drug typically begins to act within 30-60 minutes, peaks at about 1 hour, and its effects may last for up to 4-6 hours.
In Hong Kong, the Department of Health has approved sildenafil for the treatment of erectile dysfunction in adult males. The medication is indicated for men who experience difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance. It is not intended for use in women, children, or men without a diagnosis of ED.
Sildenafil is also approved in many jurisdictions for pulmonary arterial hypertension (PAH) under the brand name Revatio. This off-label use for PAH in Hong Kong is not officially sanctioned for Fildena Professional, and prescribing it for PAH would require careful medical supervision.
Disclaimer: Off-label use of any medication requires a qualified healthcare provider to assess risks, benefits, and individual patient factors.
