DESCRIPTION

Botulinum toxin, produced by the bacterium Clostridium botulinum, is one of the most potent naturally occurring neurotoxins known.  It induces chemodenervation by first binding to acceptors on motor nerve terminals.  It then enters the terminals and blocks the release of acetylcholine and other neurotransmitters at the neuromuscular junction.  This renders smooth and striated muscles incapable of contraction.  Acetylcholine also mediates the sympathetic innervation of the sweat glands, explaining how botulinum toxin disrupts the cholinergic outflow to the skin and halts glandular secretion.

The minute amount of toxin used clinically produces only partial, localized chemical denervation with transient results.  Over time, axons generate temporary sprouts which release acetylcholine and the original nerve terminal is eventually re-established, ending the toxin’s therapeutic activity.

Seven antigenic-specific serotypes of botulinum toxin have been identified, types A, B, C-1, D, E, F and G, but only botulinum toxin types A and B are commercially available.  These commercial preparations of the two serotypes (three of serotype A and one of serotype B) vary widely in potency and dosage.  They have been given different names to reinforce these differences and to prevent medication errors.  It is emphasized that the use and dosage of different formulations of botulinum toxin is not interchangeable.

This policy addresses only the type B formulation rimabotulinumtoxinB marketed as Myobloc®.
