Pharmacology
RimabotulinumtoxinB is a botulinum toxin type B that blocks cholinergic transmission at neuromuscular and salivary neuroglandular junctions by inhibiting acetylcholine release via enzymatic cleavage of synaptobrevin (VAMP), a presynaptic protein essential for vesicle fusion; nerve terminal function is restored by formation of new nerve endings.
Glycopyrrolate is a competitive inhibitor of acetylcholine receptors on peripheral tissues including salivary glands, indirectly reducing salivation by preventing stimulation of these receptors.
