| Abstract | BACKGROUND AND OBJECTIVE: Ivabradine is a novel pure heart rate-lowering agent that selectively and specifically inhibits pacemaker I(f) current. Ivabradine has been shown to have antianginal and anti-ischaemic properties in patients with stable angina pectoris. Because f channels are also present in the retina, visual symptoms represent a potential adverse effect of ivabradine that may affect driving performance. The aim of the study was to investigate whether visual symptoms reported after repeated administration of ivabradine at high doses could affect driving performance. METHODS: This randomized, double-blind, placebo-controlled study was conducted in healthy volunteers. Seventy-five subjects were randomized to ivabradine 10 mg twice daily and 15 subjects to placebo for 7 days, followed by ivabradine 15 mg twice daily or placebo, respectively, for a second week if no visual symptoms were reported. As soon as a subject reported visual symptoms between day 1 and day 14, he or she was assigned to perform driving simulator sessions. If no visual symptoms were reported, driving simulator sessions were performed after 14 days' treatment. Driving parameters included absolute speed, deviation from the speed limit, deviation from the ideal route and number of collisions in different light conditions. RESULTS: In the daylight and evening driving sessions, there was no significant difference in all measured parameters (as indicated by absolute speed, deviation from the speed limit and deviation from the ideal route results) between the ivabradine and the placebo groups, independently of visual symptoms. No collisions were observed in the entire study irrespective of the testing conditions and the treatment groups assessed. No relevant differences were seen in the ivabradine subsets of subjects reporting visual symptoms or not. CONCLUSION: This study suggests that ivabradine administered at dosages higher than those recommended in the clinic did not affect driving performance regardless of whether or not visual symptoms were present. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
