Description
Technical field
The invention belongs to technical field of pharmaceuticals, in particular to a kind of Compouneded anisodamine neostigmine sustained release tablets and its preparation
Method.
Background technique
Abroad in Recent Years the study found that cholinergic anti-inflammatory pathway be adjust immune system a kind of neurophysiological mechanism, resist
Scorching signal reaches the reticuloendothelial systems such as spleen, liver and gastrointestinal tract, subsequent vagus nerve release through descending vagal efferent
Acetylcholine, the alpha 7 nicotinic acetylcholine receptors (α 7nAchR) with macrophage and other cytokine secreting cell surfaces
Interaction, inhibits the synthesis and release of proinflammatory cytokine, control inflammation reaction, prevents tissue damage.We are in recent years
Clinical research and animal experiment also confirm that, use anticholinesterase (methyl-sulfuric acid neostigmine) and gallbladder simultaneously by a certain percentage
Alkali energy m receptor blocking agent (racemization Tangut Anisodus Radix) has " cholinergic anti-inflammatory pathway " of enhancing vagal mediation, activates α 7
The effect of nAchR.But the half-life period of methyl-sulfuric acid neostigmine and 654-2 in vivo is shorter, and (methyl-sulfuric acid neostigmine half-life period is
0.89~1.2 hour, 654-2 was only 40 minutes), the needs for continuing anti-inflammatory treatment in vivo are unable to satisfy, there is no both at home and abroad at present
Any research of the compound sustained-released tablet of both 654-2 and neostigmine is reported.
