Tadora (Tadalafil )

Tadora (Tadalafil): Comprehensive Patient Guide for Australia

Basic Product Information

Mechanism of Action

For Patients: Tadora contains the active ingredient tadalafil, which helps relax blood vessels and increase blood flow to certain areas of the body. For men with erectile dysfunction (ED), this means it can help achieve and sustain an erection when sexually stimulated. It also reduces symptoms for those with benign prostatic hyperplasia (enlarged prostate) and is approved for use in some cases of pulmonary arterial hypertension.

For Specialists: Tadalafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. It increases levels of cyclic guanosine monophosphate (cGMP) in corpus cavernosum smooth muscle by inhibiting PDE5 breakdown, resulting in smooth muscle relaxation and vasodilation. For benign prostatic hyperplasia and pulmonary hypertension, tadalafil acts on vascular and prostatic tissues via similar cGMP pathways.

Pharmacokinetics

• Absorption: Rapid absorption; peak plasma concentration in 2 hours (range 30 min–6 hours).
• Bioavailability: High oral bioavailability. Not significantly affected by food.
• Metabolism: Hepatic (mainly CYP3A4 enzyme metabolism) in the liver.
• Elimination: Mainly via faeces (61%), secondary by urine (36%).
• Half-life: Approximately 17.5 hours—considerably longer than many similar medicines.
• Duration of Action: Up to 36 hours. Sometimes called the "weekend pill" due to this long action.

Use in Everyday Life and Best Practices

• Erectile Dysfunction (ED): Most commonly, Tadora is prescribed as needed, with a tablet taken 30 to 60 minutes before anticipated sexual activity. Dosing flexibility allows for once-daily, lower doses for men who prefer not to plan sexual activity.
• Benign Prostatic Hyperplasia (BPH): Typically, a once-daily dose is prescribed. It may alleviate urinary symptoms like urgency, frequency, or poor flow.
• Pulmonary Arterial Hypertension (PAH): Adcirca brand or generic tadalafil may be prescribed under specialist care.
• Australian Context: Tadora is widely used in urban and rural settings, available at most pharmacies with a valid prescription. Discuss with your doctor whether "as needed" or daily therapy is correct for you.

Tablets should be swallowed whole with water. Avoid splitting or crushing unless directed by your pharmacist. Tadora is not intended for use in women or children.

Dosing: Morning vs Evening

• As Needed Use: Timing is usually based on anticipated sexual activity. Tadora may be effective for up to 36 hours after dosing, so flexibility is possible.
• Daily Use: Try to take your tablet at the same time each day (morning or evening) to maintain consistent levels in your system. Choose a time that fits your schedule best.
• Tips: Some people prefer morning dosing to avoid forgetting the evening dose, while others prefer evening dosing to minimise daytime side effects (such as back pain).
• Consistency: Whichever you choose, stick to the same time daily for steady effect and maximum benefit.

Taking with Food or on an Empty Stomach

Tadora can be taken with or without food. Meals, including those common in the English or Australian diet (such as a full breakfast or substantial evening meal), do not significantly affect tadalafil's absorption or its onset of action. This means you can fit your dosing routine around your usual dietary habits.

• Fatty Meals: Unlike some other ED medicines, high-fat meals do not notably delay or reduce the effect of tadalafil.
• Alcohol: Drinking moderate amounts of alcohol (up to 2 units or standard drinks) is usually safe. However, excessive alcohol intake can increase the chance of side effects such as dizziness, headache, or low blood pressure.

Guidelines for Proper Use (Pharmacist/Clinic Advice)

1. Take only as prescribed—do not exceed recommended dose.
2. Maintain regular dosing for daily therapy; try to link it to a daily habit (e.g., breakfast time).
3. If you miss a daily dose, take it when remembered unless close to your next dose; do not double dose.
4. Avoid excessive alcohol, as this can lower blood pressure and increase side effects.
5. If prescribed for BPH or PAH, ongoing GP or urologist/cardiologist review is required.
6. Report persistent side effects promptly to your healthcare provider.

Alternative Treatment Options

• Sildenafil (Viagra, generic): Effective but shorter duration (4–6 hours). Good for infrequent use. Food can delay onset.
• Vardenafil (Levitra): Similar efficacy to sildenafil. Slightly longer duration and more expensive.
• Avanafil (not widely available in Australia): Very rapid onset, may be offered in special cases.
• Non-drug therapies: Vacuum erection devices, penile injections (alprostadil), counselling for psychological ED.
• For BPH: Alpha-blockers (e.g., tamsulosin), 5-alpha reductase inhibitors (finasteride); discuss options with your doctor. Some listed on the PBS.
