Understanding Tadalafil Treatment
Tadalafil is a clinically-proven erectile dysfunction treatment containing the active ingredient tadalafil, a PDE5 inhibitor. First approved in the UK in 2003, it's available as:
- Branded Cialis® tablets (Lilly Pharma)
- Generic tadalafil tablets (available since 2017)
Key characteristics:
Strength | Duration | Pack Size |
---|---|---|
10mg/20mg | Up to 36 hours | 4-8 tablets |
While generic versions contain identical active ingredients, always check the patient leaflet (eMC) for excipient differences.
How Tadalafil Treats ED
Tadalafil enhances natural erectile function through targeted enzyme inhibition:
- Sexual stimulation releases cGMP
- Tadalafil inhibits PDE5 enzyme
- Blood vessels dilate for improved flow
- Erection maintained during stimulation
Clinical studies show 81% effectiveness rate when taken correctly (NICE, 2023). Unlike shorter-acting ED treatments, its 36-hour window allows spontaneous intimacy.
Tadalafil Treatment Options
Our pharmacy offers both treatment formats:
Branded Cialis®
- 20mg tablets
- 4-tablet packs
- Original formulation
Generic Tadalafil
- 10mg/20mg options
- 4-8 tablet packs
- Cost-effective alternative
Both require medical consultation to ensure safe use.
