METHODS: In this multicenter trial, 60 patients with symptomatic osteoarthritis of the knee and hip were included to receive Lyprinol at a dose of 2 capsules twice a day. After a 4- and 8-week treatment period, the following parameters were analyzed: visual analogue scale; Lequesne functional index; global assessment by patients; global assessment by physician; and adverse effects. RESULTS: Lyprinol treatment led to significant improvement of the signs and symptoms of osteoarthritis as determined by all efficacy measures. After a 4- and 8-week treatment period, 53% and 80% (respectively) of patients experienced significant pain relief, and improvement of joint function.
