Study summary

Hernia repair is one of the most common operations. Whilst there are few complications, pain may last for several weeks and extend the period of convalescence. ALGRX 4975 is an ultra-pure form of capsaicin, which is a pain medicine that has the potential for long-term pain relief following a single administration. This study will determine whether ALGRX 4975 can provide pain relief following hernia repair.

Read the detailed description

Inguinal hernia correction in adults is one of the most common operations with an annual rate of approximately 2,800 per 1 million people in the United States. Whilst there is little intra and postoperative morbidity, pain may persist for one to several weeks postoperatively and may extend the period of convalescence. ALGRX 4975 is an ultra-pure form of capsaicin, which is a pain medicine that has the potential for long-term pain relief following a single administration. The purpose of this study is to determine whether a single dose of ALGRX 4975, administered by instillation, is able to reduce the postoperative pain following inguinal hernia correction and to evaluate the potential for long term pain relief.
