Tadalafil vs Sildenafil - Comparing Erectile Dysfunction Prescriptions

SaveHealth, the prescription coupon website explores Tadalafil vs Sildenafil. Tadalafil (Cialis) and sildenafil (Viagra) are both FDA-approved PDE5 inhibitors used to treat erectile dysfunction (ED) by enhancing blood flow to the penis. While they share a similar mechanism of action, key differences in duration, dosing flexibility, and side effect profiles make each drug unique. This comparison explores their clinical uses, effectiveness, and practical considerations to help patients and providers make informed decisions. You can save money on Tadalafil using the SaveHealth discount card and on Sildenafil using the SaveHealth coupon price.

Tadalafil vs Sildenafil - Mechanism of Action

Both medications inhibit the PDE5 enzyme, which promotes blood vessel relaxation and improves erectile function. However, their pharmacokinetic profiles differ significantly:

Tadalafil: Long-acting (up to 36 hours) due to a half-life of 17.5 hours.

Sildenafil: Short-acting (4-6 hours) with a half-life of 3-5 hours.

	Tadalafil	Sildenafil
Onset	typically 30-60 min (may take up to 2 hours)	30 mins - 1 hour
Peak Effect	2 hours (duration of action up to 36 hours)	1 hour(delayed by up to 60 min with high fatty meal)
Food Interaction	Unaffected by meals	Reduced efficacy with high-fat foods

Clinical studies show comparable effectiveness, but usage patterns differ:

Tadalafil: Preferred for spontaneity due to its 36-hour window. Also approved for daily low-dose use (2.5-5 mg) and benign prostatic hyperplasia (BPH).

Sildenafil: Ideal for planned sexual activity, typically taken 30-60 minutes before intercourse. A meta-analysis of 16 trials found:

72-86% of men achieved improved erections with both drugs

Patients and partners slightly preferred tadalafil for psychological outcomes (SEAR confidence scores improved by 1.26 points vs. sildenafil)
