What is Tadalafil? (Cialis): Key Facts for Patients
- Generic Name: Tadalafil
- Brand Names: Cialis, Adcirca
- Form: Oral tablet
- Drug Class: Phosphodiesterase type 5 (PDE5) inhibitor
- FDA Approved Since: 2003
Mechanism of Action: How Does Tadalafil Work?
Tadalafil operates by inhibiting the PDE5 enzyme in the body, which regulates blood flow. By blocking this enzyme, Tadalafil increases levels of cyclic guanosine monophosphate (cGMP), relaxing smooth muscle cells and allowing easier blood flow to particular body areas:
- Erectile Dysfunction: Promotes increased blood flow to the corpus cavernosum of the penis after sexual stimulation.
- Pulmonary Arterial Hypertension: Relaxes blood vessels in the lungs, improving exercise capacity.
- Benign Prostatic Hyperplasia: Improves urinary symptoms by relaxing bladder and prostate muscle fibres.

Major Uses of Tadalafil (Cialis): Indications for Use
Tadalafil isn’t just “the ED pill”—it’s a multi-use medication with a growing scope. Here is where it truly shines:

- Pulmonary Arterial Hypertension (PAH): Marketed as Adcirca, this application improves exercise tolerance and quality of life for PAH patients.
- Benign Prostatic Hyperplasia (BPH): Alleviates lower urinary tract symptoms, improving urinary flow and bladder function.
