Although these medications belong to the same drug class, they differ in how quickly they work, how long they last, side effects, flexibility, and lifestyle suitability.
This comprehensive guide explains everything you need to know to understand the differences between Cialis, Viagra, and Levitra so patients can make informed discussions with healthcare professionals.
Understanding Erectile Dysfunction Medications
All three medications belong to a class called:
PDE5 inhibitors (phosphodiesterase type-5 inhibitors).
They work by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain erections.
