Therapeutic equivalency of two lidocaine preparations. 1976

J E Stambaugh, and I W Wainer, and D M Hemphill

Twenty-five volunteers were studied as to the onset and duration of action of two commercial brands of lidocaine. One and two percent concentrations of the preparations were tested intradermally using a double-blind, cross-over protocol. Both needle-drop and electrical stimulation techniques were employed as the source of pain stimulus. Five additional subjects were studied in a dose-ranging study using a placebo and lidocaine concentrations of 0.25%, 0.50%, 0.75% and 1.0%; this experiment was conduced to determine the sensitivity of the experimental methods. Both the needle-drop and electrical stimulation techniques were able to distinguish the 0.25% preparation from placebo and from the other concentrations of 1% and 2%. The two preparations were found to be statistically equivalent at concentrations of 1% and 2% and could be used interchangeably in clinical procedures.

UI	MeSH Term	Description	Entries
D008012	Lidocaine	A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.

D000704	Analysis of Variance	A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.	ANOVA,Analysis, Variance,Variance Analysis,Analyses, Variance,Variance Analyses
D000779	Anesthetics, Local	Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
