Cialis manufactured by Eli Lilly was approved by FDA in 2003. Cialis is one of the three FDA approved erectile dysfunction treatment. Tadalafil is the main content of Cialis. It works similar to other two approved drugs Viagra and Levitra. Cialis is PDE – 5 inhibitor. It works by blocking PDE – 5, the chemical that reverses an erection. The arteries in the penis are able to open wider so that more blood can flow, when this chemical is blocked.
Cialis can start working in as little as 30 minutes, and its effect can last up to 36 hours. Cialis is also known as “weekend pill” as it lasts for 36 hours, in contrast effect of Viagra and levitra lasts for 4 to 5 hours. This is the reason Cialis is different than Viagra and Levitra. Cialis can be taken with or without food, so planning around eating is not an issue. Alcohol also doesn’t affect Cialis. It is available online on prescription.
