Key points
- This PDE5 inhibitor raises cGMP levels in the tissues, relaxing smooth muscle and boosting the blood flow needed for an erection.
- It is prescribed for erectile dysfunction, with some combination tablets also addressing premature ejaculation.
- Generic versions such as Filitra, Vilitra and Valif accompany the originator brand Levitra.
- It must not be combined with nitrate medicines, which can cause a dangerous interaction, or with grapefruit products.
What is Vardenafil?
Vardenafil is a PDE5 inhibitor, a class of compounds that relaxes muscles in the blood vessel walls. By encouraging blood flow in specific areas, it assists in achieving and maintaining an erection during physical intimacy. Because it is produced by various manufacturers, patients have access to multiple brands that may differ in presentation and secondary ingredients.
What Vardenafil is used for
This medication is primarily used to address Erectile Dysfunction. Some formulations include additional active ingredients to support the management of Premature Ejaculation. These combination products serve as dual-action preparations for those looking to address both concerns with a single administration.
How does Vardenafil work?
Vardenafil works by blocking an enzyme known as phosphodiesterase type 5 (PDE5). Under normal sexual stimulation, this blockade allows levels of cyclic guanosine monophosphate (cGMP) to rise within the tissues. Higher cGMP levels cause smooth muscles to relax and blood vessels to widen, which increases blood flow necessary for an erection.
Vardenafil brands and forms
Patients may select from a variety of formulations within the Erectile Dysfunction category, ranging from the originator brand (Levitra) to generic versions like Vilitra, Filitra, and Valif. Some brands, such as Super Zhewitra or Levitra Super Force, incorporate a second active ingredient to provide combined benefits. These are typically available as oral film-coated tablets or standard tablets, designed for reliable absorption. Those seeking to address Premature Ejaculation may also find combination tablets suitable.
