Problems solved by technology

[0003] At present, the montmorillonite preparations on the market mainly include powders, granules, suspensions and dispersible tablets. These dosage forms have some shortcomings: powders and granules have a gritty and earthy smell when they are mixed with water and taken evenly, which is not easy for patients to accept. Suspensions also have the problem of poor taste; dispersible tablets can be swallowed directly, but the effective dose of this product is relatively large, so the specifications of commercially available dispersible tablets are 1g / tablet, which is difficult to swallow, especially in infants and young children and adolescents when taking
[0004] The document "Azithromycin Taste-Masked Pellets Dry Suspension" reports that Azithromycin is made into pellets, and then adding a suspending agent to make taste-masked pellets dry suspension, but in production practice, due to the prepared pellets and necessary Excipients, such as suspending agents, flavoring agents and essences, have different shapes and particle sizes, so the uniformity of the product cannot be guaranteed in the mixing and filling process
[0005] Through comparison, it is found that the existing montmorillonite preparations generally have a series of problems such as poor taste and inconvenient taking.
