Cialis Daily (Tadalafil) – Comprehensive Guide for Australia Patients
Basic Product Information
- International Nonproprietary Name (INN): Tadalafil
- Brand Names in Australia: Cialis Daily, Adcirca (for PAH), and generic Tadalafil
- ATC Code: G04BE08
- Available Forms & Strengths:
- Tablets: 2.5 mg, 5 mg (Cialis Daily); 10 mg, 20 mg (as-needed dosing)
- Common Manufacturers: Eli Lilly Australia Pty Ltd, reputable generics manufacturers (e.g., Apotex, Sandoz)
- Prescription Status: Prescription Only Medicine (Schedule 4 - S4 in Australia)
Mechanism of Action
For Patients: Cialis Daily (Tadalafil) is a medication that helps increase blood flow to the penis, making it easier to get and maintain an erection when sexually stimulated. It does not cause an erection on its own—sexual arousal is still needed for the medicine to work.
For Specialists: Tadalafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing cyclic guanosine monophosphate (cGMP) concentrations, resulting in smooth muscle relaxation and vasodilation in the corpus cavernosum of the penis.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration with peak plasma concentrations at about 2 hours post-dose.
- Metabolism: Mainly hepatic (CYP3A4 enzyme pathway).
- Elimination: Mostly excreted as metabolites in faeces and urine.
- Duration of Action: Long half-life (approximately 17.5 hours), supporting once-daily use.
Everyday Use & Best Practices (Australia Context)
Cialis Daily is designed for men who prefer more spontaneity in their sexual activity, as it maintains a steady level of Tadalafil in the body. The typical recommended starting dose is 2.5 mg once daily, which may be increased to 5 mg once daily based on effectiveness and tolerability, as advised by your doctor.
- Swallow the tablet whole with water at about the same time every day.
- Do not exceed the recommended dose unless your doctor advises otherwise.
- Missed a dose? Take it as soon as you remember, but do not take double doses.
Dosing in the Morning vs Evening
- Morning: Fits common routines, less likely to forget. For some, aligns better with weekend plans or morning activity.
- Evening: May suit those whose regular sexual activity occurs at night. Night-time dosing can also help minimize awareness of side effects like headache or flushing while sleeping.
- Tips: Take at the time that fits best in your daily routine for improved adherence.
Taking with Food or on an Empty Stomach
Cialis Daily can be taken with or without food. Both light and heavy English meals (including full breakfast or dinner) have minimal impact on the absorption and effectiveness of Tadalafil. Patients are generally advised to maintain their usual diet and avoid excessive intake of fatty foods that might temporarily delay absorption.
