Problems solved by technology

Therefore, the orally disintegrating tablets made of these excipients have relatively strict environmental requirements during production, storage and transportation, and special packaging, sealing caps, desiccant bags, etc. must be used, which will have a great impact on production costs.
Moreover, the above-mentioned disintegrants are all synthesized through a chemical process, and the price is relatively high. For orally disintegrating tablets with a relatively large content of excipients, it will lead to increased production costs and further increase the economic burden on patients.
