Improved Lidocaine Formulation Minimizes Pain at Injection Site While Maintaining Effectiveness
Administered in more than 1 million cutaneous surgeries per year, local anesthesia injections are viewed as a very painful part of minor surgery. Additionally, the lidocaine for such formulations is in short supply. In response to these issues, UCF researchers have developed a new lidocaine/epinephrine formulation. The UCF invention uses 10 times less lidocaine than the current standard solution of 1 percent, yet maintains its efficacy and is significantly less painful when injected.
The invention consists of an anesthetic solution of 0.1 percent lidocaine, along with epinephrine, saline and a buffering agent.
