What is Tadalafil? (Cialis, Adcirca & More Explained)
- Prescription medication used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH)
- Brand names: Cialis (ED & BPH), Adcirca (PAH)
- Belongs to the class: PDE5 inhibitors (phosphodiesterase type 5)
How Does Tadalafil Work? (Mechanism of Action)
Tadalafil boosts blood flow by selectively inhibiting the PDE5 enzyme in the smooth muscle of the blood vessels—primarily those supplying the penis, but also in other parts of the body. When this enzyme is blocked, cyclic guanosine monophosphate (cGMP) sticks around longer, relaxing blood vessels and letting more blood flow in. This means improved, sustained erections in response to sexual stimulation and easier urination in BPH.
- Erectile Dysfunction: More blood reaches the penis for a firm, lasting erection (requires sexual arousal!)
- BPH: Relaxes muscles in the prostate and bladder for better urine flow
- PAH: Lowers blood pressure in the lungs to improve exercise capacity
Tadalafil vs. Viagra (Sildenafil) and Other ED Pills
| Drug | Onset | Duration | Food interaction? |
|---|---|---|---|
| Tadalafil (Cialis) | 30-60 minutes | Up to 36 hours | No significant effect |
| Sildenafil (Viagra) | 30-60 minutes | 4-6 hours | Reduced by fatty meals |
| Vardenafil (Levitra) | 30-60 minutes | 5-8 hours | Slight effect from food |
Tadalafil stands out for its long duration and steady effect, making it ideal for spontaneous intimacy.
