סממני תרפויטית:

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. Nesacaine and Nesacaine-MPF Injections are contraindicated in patients hypersensitive (allergic) to drugs of the PABA ester group. Lumbar and caudal epidural anesthesia should be used with extreme caution in persons with the following conditions: existing neurological disease, spinal deformities, septicemia, and severe hypertension.

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), which
is represented by the following structural formula:
The solutions are adjusted to pH 2.7 to 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.
Systemic absorption of local anesthetics produces effects on the
cardiovascular and
central nervous systems. At blood concentrations achieved with normal
therapeutic
doses, changes in cardiac conduction, excitability, refractoriness,
contractility, and
peripheral vascular resistance are minimal. However, toxic blood
concentrations
depress cardiac conduction and excitability, which may lead to
atrioventricular block and
ultimately to cardiac arrest. In addition, with toxic blood
concentrations myocardial
contractility may be depressed and peripheral vasodilation may occur,
leading to
decreased cardiac output and arterial blood pressu
