Viagra and Cialis are two of the most popular medications used to treat erectile dysfunction (ED), a condition that affects millions of men worldwide. While both drugs serve a similar purpose, they have unique characteristics that make them suitable for different individuals. This article explores the key differences, similarities, benefits, and precautions associated with these medications.

What Are Viagra and Cialis?

Viagra (sildenafil) and Cialis (tadalafil) belong to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. These medications work by increasing blood flow to the penis, helping men achieve and maintain an erection during sexual stimulation.

• Viagra: Developed by Pfizer, Viagra is typically taken 30-60 minutes before sexual activity. Its effects last for about 4-6 hours.

• Cialis: Manufactured by Eli Lilly, Cialis offers a longer duration of action, lasting up to 36 hours. It can be taken as needed or in a lower daily dose for continuous use.
