Methods: This was a single center, randomized, double-blind, placebo-controlled, twofold crossover study with an administration of a single oral dose of two 20 mg tablets of BAY 38–9456 (vardenafil hydrochloride) or corresponding placebo in 24 healthy male subjects. Ocular investigations included Farnsworth–Munsell D100 color vision test, electroretinogram, and basic ophthalmological examinations like visual acuity, visual field, and slit-lamp of anterior segment and fundus.

While latency of electroretinogram b-wave remained unaffected, amplitudes showed a significant decrease compared to placebo 1 hour following administration.

Keywords: phosophodiesterase-5 inhibitor, retinal function, color vision, electroretinogram, adverse events, placebo-controlled Vardenafil (Levitra®; Bayer AG, Leverkusen, Germany) has been developed as an inhibitor of phosphodiesterase 5 (PDE-5) for the treatment of erectile dysfunction. PDE-5 inhibitors like vardenafil or sildenafil (Viagra®) do not have a direct relaxant effect on the corpus cavernosum; however, they enhance the effect of nitric oxide (NO) by inhibiting PDE-5, which is responsible for degradation of cyclic guanosine monophosphate in the corpus cavernosum.1 When sexual stimulation causes local release of NO, inhibition of PDE-5 by vardenafil causes smooth muscle relaxation and inflow of blood to the corpus cavernosum.2,3 Vardenafil has been shown to be effective and safe when administered to patients with erectile dysfunction in placebo-controlled studies over a dose range of 5–20 mg once daily and up to 40 mg twice daily in multiple-dose Phase I and II studies.4–6 The most frequent adverse events (AEs) were headache, flush, rhinitis, and dyspepsia.7,8 Typical ocular side effects seen under treatment with PDE-5 inhibitors are disturbed color vision and temporary effects on the electroretinogram (ERG), which may be due to the fact that PDE-6, typically located in the eye, is also inhibited to a certain degree by PDE-5 inhibitors;9–14 this may depend on the selectivity of PDE-5 inhibition.15 However, these side effects have been exclusively investigated for sildenafil.

Therefore, this study was designed to especially investigate the possible influence of vardenafil-induced PDE-5 inhibition on ocular side effects and the function of the retina. The primary objective of the study was to investigate the possible influence of a single oral dose of 40 mg of vardenafil on color vision in normal-eyed male subjects measured by performing Farnsworth–Munsell 100 test at 1, 6 and 24 hours after drug administration.
