Mechanism of Action
- For patients: Tadalafil helps treat difficulty achieving or maintaining erections (erectile dysfunction) by increasing blood flow to the penis during sexual stimulation. It does so by relaxing muscles and blood vessels in the penis.
- For specialists: Tadalafil is a selective, reversible phosphodiesterase type 5 (PDE5) inhibitor. It increases cGMP concentrations in corpus cavernosum smooth muscle, improving erectile function in response to sexual stimulation. It is also used to reduce symptoms in benign prostatic hyperplasia (BPH) and pulmonary arterial hypertension (PAH) by relaxing smooth muscle in prostate, bladder, and pulmonary vasculature.
Pharmacokinetics
- Absorption: Well absorbed orally; peak plasma concentration reached in 30 minutes to 2 hours.
- Metabolism: Mainly hepatic (liver) via CYP3A4 isoenzyme.
- Elimination: Half-life approx. 17.5 hours. Excreted mostly in faeces (61%), some in urine (36%).
- Duration of action: Up to 36 hours post-dose; hence, sometimes called the "weekend pill."
Use in Everyday Life and Best Practices
Tadalista Professional is commonly prescribed for erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). In Australia, you must have a valid prescription from a GP or specialist, in accordance with local laws (Therapeutic Goods Administration — TGA).
- Erectile Dysfunction (ED): Take 1 sublingual tablet (20 mg) before anticipated sexual activity. The medication is placed under the tongue for faster absorption and is not meant for daily use unless directed by a doctor.
- Benign Prostatic Hyperplasia (BPH): The tablet may be used daily in a lower dose. Follow your doctor’s instructions closely.
- Pulmonary Arterial Hypertension (PAH): Dosing is individualised and usually lower than for ED. Specialist supervision required.
- Use only as directed. Do not exceed one dose in a 24-hour period unless specifically advised by a specialist.
Dosing in the Morning vs Evening
- For ED: Timing is flexible due to long duration of action (up to 36 hours). May be taken in the morning or evening based on personal preference.
- Advantages of Morning Dosing: Enables spontaneity throughout the day and avoids late-night disruptions.
- Advantages of Evening Dosing: May be preferable if sexual activity is typically at night. For daily dosing (BPH, PAH), take at the same time every day to maintain stable blood levels.
- Tip: Establishing a routine time aids adherence and reduces chances of missed doses.
Taking with Food or on an Empty Stomach
- Effect of Meals: Tadalista Professional (sublingual tadalafil) may be taken with or without food. High-fat meals may delay the onset very slightly—effect is not pronounced compared to some other ED medicines (e.g., sildenafil).
- Australian Dietary Habits: No special dietary adjustments needed. You may take your regular breakfast, lunch or dinner. Limit heavy alcohol intake as this may increase side effects.

Guidelines for Proper Use (Advice from Pharmacists and Clinics)
- Always use Tadalista Professional according to your doctor’s instructions. Do not share your medicine.
- Do not crush, chew, or swallow the sublingual tablet—let it dissolve under the tongue for best absorption.
- If you miss a dose (for daily use), take it as soon as you remember, but not if it’s nearly time for the next dose.
- Keep tablets in their original packaging, stored below 25°C, away from moisture and out of sight of children.
- If you experience chest pain, sudden vision changes, or an erection lasting more than 4 hours, seek emergency care.
- Regular GP check-ups are important if using daily for BPH or PAH.
- Check expiry date before use. Return unused/expired medicine to your local pharmacy for safe disposal.
Alternative Treatment Options
- Sildenafil (Viagra & generics): Shorter duration (4–6 hrs), possibly quicker onset. Also subsidised under PBS for certain conditions. More sensitive to food delays. Side effects similar to tadalafil.
- Vardenafil (Levitra, Vivanza): Similar to sildenafil but slightly longer effect, less food interaction; not all forms PBS-listed.
- Avanafil (Spedra): Fastest onset (15 min), slightly shorter duration; not widely PBS-subsidised.
- Mechanical devices (penile pump): Non-drug option, suitable for some men who cannot take PDE5 inhibitors.
- Testosterone therapy: Only if hormone deficiency confirmed. Specialist management only.
- Papaverine/alprostadil injection/urethral suppositories: Reserved for non-responders to oral therapy.
- Counselling/psychotherapy: Recommended if anxiety, stress, or psychological factors contribute.
Pros & cons: Tadalafil offers a longer duration and flexible timing, but is more expensive than sildenafil and not always fully PBS reimbursed unless for PAH. Individual preference and tolerance are important; discuss with your doctor.
Legal, Registration, and Reimbursement Status in Australia
- Registered and regulated by the Therapeutic Goods Administration (TGA) as a Schedule 4 medicine (Prescription Only).
- Pharmaceutical Benefits Scheme (PBS): Subsidy/reimbursement available only for certain indications (mainly PAH, not ED or BPH unless exceptional approval).
- Must be prescribed by an Australian-registered doctor — not available over the counter.

Latest Research and Clinical Guidance (2022–2025)
- Sexual Medicine Society of Australia (SMSA), 2022–2024: Recommends PDE5 inhibitors as first-line therapy for ED. Tadalafil preferred for those desiring extended period of effect or daily BPH therapy.
- International Journal of Clinical Practice, 2023: Tadalafil daily may also reduce lower urinary tract symptoms in men with BPH and improve quality of life.
- NICE (UK), 2024: Reaffirms efficacy, safety, and improved compliance with daily low-dose tadalafil compared to demand dosing in selected populations. No new major warnings issued.
- Ongoing TGA post-marketing surveillance (2022–2025) continues to support tadalafil’s favourable safety profile when used as prescribed.
