DS-5565 inhibited RR (ID50: 9.4 mg/kg) and LA (ID50: 43.9 mg/kg) and the ratios ID50/ED50 (CNS safety margin) were ca 3.8 in RR and ca 18 in LA. The ratios for PGB were 0.4 and 3.9, respectively. CONCLUSIONS: DS-5565 has superior analgesic effects with a wider CNS safety margin relative to PGB. These profiles of DS-5565 are possibly due to its unique binding characteristics to α2δ-1 and α2δ-2.Disclosure: Dr. Yokoyama has received personal compensation for activities with Daiichi Pharmaceutical Corp. as an employee.
