Difference between Viagra and Cialis: An Overview
Viagra and Cialis are two popular drugs used to treat erectile dysfunction (ED). Both drugs are effective in improving sexual performance, but they work differently and have different side effects. In this article, well explore the differences between Viagra and Cialis to help you make an informed decision about which drug is right for you.
How Do Viagra and Cialis Work?
Viagra and Cialis are both phosphodiesterase type 5 (PDE5) inhibitors. They work by increasing blood flow to the penis, which helps to achieve and maintain an erection during sexual stimulation.
Viagra contains sildenafil citrate, which inhibits PDE5 and increases nitric oxide levels in the body. This causes the muscles in the penis to relax, allowing blood to flow into the penis and produce an erection.
Cialis contains tadalafil, which also inhibits PDE5 and increases nitric oxide levels. However, Cialis has a longer half-life than Viagra, meaning it stays in the body longer and can be effective for up to 36 hours.
Effectiveness
Both Viagra and Cialis are effective in treating ED, but studies have shown that Cialis may be more effective for some men.
One study found that 81% of men who took Cialis reported improved erections compared to 71% of men who took Viagra. Another study found that men reported greater satisfaction with Cialis compared to Viagra.
However, individual responses to these drugs can vary, so its important to talk to your healthcare provider about which drug is right for you.

Dosage and Timing
The recommended starting dose for Viagra is 50mg, taken one hour before sexual activity. The dose can be adjusted based on individual response and tolerability.
