Innovative Nasal Anaesthetic Spray Outperforms Co-phenylcaine for Dental Procedures

Posted: January 4, 2025
The study compared the anaesthetic efficacy of tetracaine and oxymetazoline with Co-phenylcaine in nasal instrumentation. Results showed that tetracaine-based sprays provided more potent topical anaesthesia with a better taste compared to Co-phenylcaine. Tetracaine 2% with oxymetazoline 0.05% had a faster onset, longer duration of action, and higher sensory threshold than Co-phenylcaine. Dental numbness was more common with tetracaine-based sprays. This research highlights tetracaine 2% with oxymetazoline 0.05% as a superior anaesthetic-decongestant spray for nasal procedures.
