Sample Use Guides

In Vivo Use Guide
In a phase II study, treatment with single 400 mg dose of E 52862 before hysterectomy showed a clinically relevant reduction in pain intensity up to 24 hours post-surgery and a meaningful reduction for the need of concomitant anti-emetic medication in patients undergoing abdominal hysterectomy.
Route of Administration: Oral
In Vitro Use Guide
30 uM S1RA (E-52862) inhibited the spinal nociceptive C-fibre–dependent wind-up phenom-enon found when trains of stimuli were applied
