Dose Adjustments
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.
What are some things I need to know or do while I take this drug?
Vardenfil has been studied and determined by very few procedures: high-performance liquid chromatography-electro spray ionization mass spectrometry [3] and micellar electrokinetic capillary 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.
