The trials involved offering a regimen of pills to about 300 patients experiencing pain after undergoing one of two surgical operations—either a bunionectomy or an abdominoplasty (more commonly known as a tummy tuck).

这些试验涉及向大约 300 名在接受两种外科手术中的一种手术后感到疼痛的患者提供一种药物治疗方案——拇囊炎切除术或腹部整形术（通常称为腹部除皱术）。

It failed to achieve satisfactory results in a phase-2 clinical trial, however, for acute pain for patients who had just undergone a bunionectomy, a procedure that involves the removal of enlarged bone regions in the foot.

然而，它未能在 2 期临床试验中取得令人满意的结果，该试验针对刚刚接受过拇囊炎切除术的患者的急性疼痛，该手术涉及去除足部扩大的骨骼区域。
