Lidocaine/tetracaine medicated plaster: in minor dermatological and needle puncture procedures.
The lidocaine/tetracaine medicated plaster comprises a lidocaine/tetracaine 70 mg/70 mg patch and a controlled heat-assisted drug delivery pod that increases the diffusion of lidocaine and tetracaine into the dermis. Following a 1-hour application period, systemic absorption of lidocaine or tetracaine from the plaster was minimal. The lidocaine/tetracaine medicated plaster provided effective pain relief for adult (including elderly) patients undergoing minor dermatological procedures and for adult and paediatric patients undergoing vascular access procedures. In randomized, double-blind clinical trials, patient-reported median pain scores were significantly lower with the lidocaine/tetracaine medicated plaster than with an identical plaster containing placebo in patients undergoing minor dermatological or vascular access procedures. Furthermore, patient-reported median pain scores were significantly lower with the lidocaine/tetracaine medicated plaster than with a lidocaine/prilocaine cream in patients undergoing vascular access procedures. In a large, randomized, double-blind trial in paediatric patients undergoing venipuncture, the overall incidence of pain was significantly lower with the lidocaine/tetracaine medicated plaster than with a lidocaine/prilocaine plaster. The lidocaine/tetracaine medicated plaster was well tolerated, with the most frequent treatment-related adverse events resolving spontaneously.
