APP Pharmaceuticals, LLC
For Infiltration and Nerve Block
DESCRIPTION
Nesacaine and Nesacaine-MPF Injections are sterile non pyrogenic local anesthetics. The active ingredient in Nesacaine and Nesacaine-MPF Injections is chloroprocaine HCl (benzoic acid, 4-amino-2-chloro-2-(diethylamino) ethyl ester, monohydrochloride), The solutions are adjusted to pH 2.7�4.0 by means of sodium hydroxide and/or hydrochloric acid. Filled under nitrogen.
Nesacaine and Nesacaine-MPF Injections should not be resterilized by autoclaving.
CLINICAL PHARMACOLOGY
Chloroprocaine, like other local anesthetics, blocks the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination and conduction velocity of affected nerve fibers. Clinically, the order of loss of nerve function is as follows: (1) pain, (2) temperature, (3) touch, (4) proprioception, and (5) skeletal muscle tone. INDICATIONS AND USAGE
Nesacaine 1% and 2% Injections, in multidose vials with methylparaben as preservative, are indicated for the production of local anesthesia by infiltration and peripheral nerve block. They are not to be used for lumbar or caudal epidural anesthesia.
Nesacaine-MPF 2% and 3% Injections, in single dose vials without preservative and without EDTA, are indicated for the production of local anesthesia by infiltration, peripheral and central nerve block, including lumbar and caudal epidural blocks.
Nesacaine and Nesacaine-MPF Injections are not to be used for subarachnoid administration.
