Lidocaine USP, sometimes referred to as lidocaine “free base” because it is not bound with chloride and water, has a molecular weight of 234.34. By comparing the molecular weights, you can see a salt ratio of free base to HCl monohydrate salt of 1:1.23. Lidocaine USP is not soluble in...
prepare a sustained-release coating solution with a weight and volume percentage of 5%, and use a fluidized bed process to coat the drug-loaded pellets coated with the isolation layer prepared in step (2). The sustained-release coating solution is coated to obtain a Trospium chloride sustained-...
