Fildena Professional (Sildenafil Citrate)

Fildena Professional (Sildenafil Citrate): Comprehensive Patient Guide for Australia

Basic Product Information

Mechanism of Action

For Patients: Sildenafil Citrate helps men achieve and maintain an erection by relaxing blood vessels in the penis, making it easier for blood to flow in when sexually aroused.
For Specialists: Sildenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). It enhances nitric oxide effects by increasing cGMP, leading to smooth muscle relaxation in the corpus cavernosum, thus facilitating penile erection during sexual stimulation.

Pharmacokinetics

• Absorption: Rapidly absorbed orally, with peak plasma concentrations (Tmax) reached within 30–120 minutes (median ~1 hour). Sublingual forms may act faster.
• Metabolism: Extensively metabolised in the liver by CYP3A4 (major) and CYP2C9 (minor).
• Elimination: Main excretion via faeces (80%) and urine (13%).
• Duration of Action: Effects last about 4–6 hours, with some individual variation.

Use in Everyday Life and Best Practices

• Typical Doses: Adults usually start with 50 mg, taken as needed about one hour prior to sexual activity. Based on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. Maximum recommended dosing frequency is once per day.
• How to Use: Swallow the tablet whole with water. For rapid effect, sublingual forms can be placed under the tongue to dissolve.
• Australian Context: Prescribed under GP guidance, discussed openly to ensure safe outcomes. Confidential consultations are standard across Australia. Pharmacists are trained to advise on proper use and safety.

Dosing: Morning vs Evening Use

• Morning Use: Rare; usually less effective due to lower likelihood of sexual activity after waking. May be considered for specific circumstances (e.g., shift workers).
• Evening Use: Most common, aligns better with natural sexual activity patterns. Ensures optimal privacy and effectiveness.
• Tips for Regularity: There's no requirement for fixed daily dosing – timing is flexible and based on planned sexual activity.

Taking with Food or on an Empty Stomach

• For best results, take on an empty stomach or after a light meal.
• High-fat meals (common in some English/Australian diets) may delay absorption and onset. Avoid heavy, greasy foods beforehand for quicker results.
• Low-fat meals or standard English fare (e.g., grilled fish, salad) are less likely to interfere with efficacy.
