Valif (Vardenafil) is primarily available in oral tablet form and not as an extended-release formulation. Valif is a medication used to treat erectile dysfunction in men. It contains Valif 20, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.

These PDE5 inhibitors are typically fast-acting and are designed to be taken as needed, shortly before sexual activity. They work by increasing blood flow to the penis, helping to achieve and maintain an erection.

While there are extended-release formulations for some medications, there was no widely recognized extended-release version of Valif (Vardenafil) at the time of my last update. However, pharmaceutical products and their availability can change over time, so I recommend checking with a healthcare professional or a reliable pharmacy for the most up-to-date information on available formulations and dosages of Valif or any other medication.
