Vardenafil is used to treat erectile dysfunction in men, i.e. impotence, inability to get an erection. Vardenafil belongs to a group of drugs called phosphodiesterase inhibitors. This drug works by increasing blood flow to the penis during sexual arousal. This increased blood flow causes an erection. Vardenafil does not treat erectile dysfunction or increase sexual desire. It also does not prevent pregnancy or the spread of sexually transmitted diseases such as human immunodeficiency virus (HIV).
Vardenafil is almost ten times more potent biochemically than sildenafil, so a lower dose is required to facilitate penile erection. This potentially causes fewer side effects. The effectiveness of the drug is related to its ability to bind to the specific enzyme phosphodiesterase type-5 found in penile tissues. Vardenafil has potentially less side effects than sildenafil. Vardenafil is generally safe and serious side effects are rare.
Erectile dysfunction is a condition in which the penis does not become erect and enlarge when a man is sexually excited or unable to maintain an erection. When a man is sexually aroused, his body's normal response is to increase blood flow to his penis to create an erection. Vardenafil's job is to help maintain an erection after touching the penis by controlling the enzyme. Vardenafil does not cause an erection without physical effects on the penis, such as those that occur during intercourse.
Briefly, vardenafil is a drug used to relax the smooth muscle of the penis to increase blood flow and increase erection. It is a type of phosphodiesterase inhibitor. This drug is one of the active ingredients in viagra.
A simple high-performance liquid chromatographic (HPLC) method with photometric detection is used for the determination of vardenafil hydrochloride, a phosphodiesterase type-5 inhibitor, in human plasma.
Vardenafil, a phosphodiesterase type-5 inhibitor approved by the American Food and Drug Administration (FDA), is widely used in the treatment of male impotence due to its strong pharmacodynamic activity. Today, a large number of food supplements are subject to illegal adulteration, and detecting the presence of vardenafil in them is important because of its toxicological risks. A simple, fast and reliable high performance liquid chromatography method with ultraviolet detector has been developed for the analysis of vardenafil in herbal food supplements.
Our company also provides vardenafil determination services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
