AKTEN

Lidocaine may be absorbed following topical administration to mucous membranes. Its rate and extent of absorption depend upon various factors such as concentration, the specific site of application, viscosity of the agent, and duration of exposure. The plasma binding of lidocaine is dependent on drug concentration, and the fraction bound decreases with increasing concentration. At concentrations of 1 to 4 mcg of free base per mL, 60 to 80 percent of lidocaine is protein bound. Binding is also de...

The effect of AKTEN® on ocular anesthesia was studied in a multi-center, randomized, controlled, double-blind study. A total of 209 subjects were enrolled, with 54, 51, 53, and 51 subjects randomized to the sham, AKTEN® 1.5%, AKTEN® 2.5%, and AKTEN® 3.5% groups, respectively. Ocular anesthesia was achieved within 5 minutes of anesthetic application by 47 of 51 subjects (92%) in the AKTEN® 3.5% group. The mean time to anesthesia onset ranged from 20 seconds to 5 minutes and was not affected by AKTEN® dose. The mean time to anesthesia onset was approximately 60 seconds, with a median onset time ...
