Controlled administration of chemodenervating pharmaceuticals
First Claim
1. A method of preserving teeth in vivo by decreasing spasm of involuntary contraction in a muscle or group of muscles of a patient induced by pathologic neutral stimulation caused by involuntary jaw clenching, the method comprising:
- providing a chemodenervating pharmaceutical characterized in that a unit quantity of said pharmaceutical has been determined to denervate a predetermined volume of said muscle or said group of muscles;
determining a dose of said pharmaceutical required to denervate the predetermined volume of muscle without inducing significant paresis in muscle tissue adjacent said predetermined volume; and
injecting a chemodenervating preparation into at least one of the muscles selected from the group consisting of the masseter, temporalis, and pterygoid in an amount sufficient to diminish involuntary jaw clenching while permitting voluntary muscle stimulation, thereby retarding premature tooth wear.

Abstract
This invention relates to a method for controlled administration of chemodernervating agents such as botulinum toxin-derived pharmaceutical, useful in attenuating neural stimulation and spasmodic activity of muscle. The method involves administration of novel dosage forms based upon the standardization of denervating pharmaceuticals. The invention also relates to novel methods of administrating chemodernervating agents in a controlled and reproducible manner so as to confine their effects to a given region of muscle mass while minimizing in adjacent muscle tissue.

2. A method of decreasing spasm or involuntary contraction in a muscle or group of muscles of a patient induced by pathologic neural stimulation caused by cerebrospinal injury or stroke, the method comprising:
-
providing a chemodenervating pharmaceutical characterized in that a unit quantity of said pharmaceutical has been determined to denervate a predetermined volume of said muscle or group of muscles; determining a dose of said pharmaceutical required to denervate the predetermined volume of muscle without inducing significant paresis in muscle tissue adjacent said predetermined volume; and injecting directly into said muscle or muscle group of said patient said dose of said pharmaceutical thereby to decrease the spasm or involuntary contraction in said muscle or muscle group while permitting voluntary muscle stimulation.
