Vardenafil, which is used to control erectile dysfunction, is a potent and selective inhibitor of phosphodiesterase type 5 (PDE-5) [1]. Its chemical structure differs from that of sildenafil and tadalafil, reflecting differing pharmacological properties. Studies in men with erectile dysfunction have shown that single doses of vardenafil 10–40 mg were rapidly absorbed following oral administration, with maximum plasma concentrations (Cmax) reached in some men within 15 min. Vardenafil has a mean absolute bioavailability of 15% following oral administration [2]. Therefore, development of more effective analytical method is required for the routine analysis of vardenafil in biological fluids.
Vardenfil has been studied and determined by very few procedures: high-performance liquid chromatography-electro spray ionization mass spectrometry [3] and micellar electrokinetic capillary blue sex pills chromatography [4]. The main problems encountered using such methods are either the need for derivatization or the need for time-consuming extraction procedures. Since these techniques have a slightly expensive instrumentation and high running costs, the use of simpler, faster and less expensive, but still sensitive, electrochemical techniques can be an alternative. Electroanalytical techniques have been used for the determination of a wide range of drug compounds [5], [6], [7], [8], [9], [10]. Additionally, application of electroanalytical techniques includes the determination of electrode reaction mechanism.

Store the tablets at room temperature and away from excess heat and moisture (not in the bathroom). Store the suspension at room temperature or in a refrigerator, but do not freeze it. Dispose of any unused vardenafil cost suspension after 60 days. It is important to keep all medication out of sight and reach of children, as many containers (such as weekly pill minders and those for eye drops, creams, patches and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — out of their sight and reach.
Unneeded medications should be disposed of in special ways to ensure that pets, children and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program.
Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website for more information if you do not have access to a take-back program.19 Keep this medication in the container it came in, tightly closed and out of reach of children.

Redox properties of drugs can give insights into their metabolic fate or their in vivo redox processes or pharmacological activity. There appears to be no analytical methods for the determination and oxidation mechanism of vardenafil, in bulk form, pharmaceutical dosage forms and biological fluids that have been reported up-to-date. The aim of this work was to study the electrochemical behavior and oxidation mechanism of vardenafil at glassy carbon electrode and the development of new voltammetric methods for the direct determination of vardenafil in raw material, pharmaceutical tablets and spiked human serum. Check access to the full text by signing in through your organization. Voltammetric measurements were performed using BAS 100 W electochemical analyzer.
The three-electrode system consisted of a glassy carbon working electrode, Ag/AgCl (3 M KCl) reference electrode and a Pt auxiliary electrode. Before each measurement, the glassy carbon electrode was polished with aqueous slurry of 0.01 μm alumina powder on a damp polishing cloth until a mirror-like finish was obtained. Operating conditions for OSW were: pulse amplitude, 25 mV; frequency, 15 Hz; potential step, 4 mV and In order to understand the electrochemical behavior occuring on the glassy carbon electrode, cyclic (CV) and linear sweep voltammetry (LSV) were carried out. Differential pulse (DPV) and Osteryoung square-wave (OSW) voltammetric techniques were developed for the quantitative determination of vardenafil.
Additionally, application of electroanalytical techniques includes the determination of electrode reaction mechanism.
