Abstract

The invention discloses a methylsulfonic acid pridinol oral disintegrating tablet and a preparation method thereof, wherein the oral disintegrating tablet comprises the following components by mass percentage: 2 to 8 percent of methylsulfonic acid pridinol, 40 to 80 percent of filler, 5 to 20 percent of disintegrant, 5 to 30 percent of effervescent agent, 1 to 5 percent of lubricant and 0.5 to 5 percent of flavoring agent. The methylsulfonic acid pridinol oral disintegrating tablet can be quickly disintegrated in mouth cavity and quickly absorbed, and takes effect quickly, has small first-passeffect on liver, high bioavailability, low acrimony to gastrointestinal tract, convenient taking and good taste, and is particularly suitable for the old, children and patients with difficult swallowing or inconvenient drinking of water, or in operation or coma; and the oral disintegrating tablet is prepared by adopting a method of wet granulation and compression or a method of direct compressionof powder, has simple production technique, low cost, easily-controlled quality, and stability, safety and effectiveness of the preparation, is suitable for large-scale industrial production and haswide market prospect.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a pridinol mesylate orally disintegrating tablet, and also relates to a preparation method of the orally disintegrating tablet. Background technique [0002] Pridinol Mesilate (Pridinol Mesilate, the following structural formula) is a depolarizing muscle relaxant that can bind to N on the motor nerve endplate membrane. 2 The combination of receptors can cause long-lasting depolarization of muscle cell membranes, weaken or disappear the response to acetylcholine, and lead to relaxation of skeletal muscles. It has a good curative effect; it can also be used as an auxiliary agent for general anesthesia. Under shallow general anesthesia, it can obtain the muscle relaxation required for surgery, thereby reducing the amount of general anesthesia. At present, the preparations of pridinol mesylate on the market abroad mainly include ordinary compressed tablets, coated tablets, enteric-coa...
