In tablet formulations, HPMC serves multiple functions. It acts as a binder, ensuring the cohesion of granules during compression, which is crucial for maintaining tablet integrity. Additionally, HPMC can function as a disintegrant, promoting the breakdown of tablets in the gastrointestinal tract and thereby enhancing drug absorption. When used in controlled-release tablets, HPMC creates a gel-like barrier around the drug, allowing for a slow and continuous release of the active pharmaceutical ingredient (API) over time. This is particularly beneficial for drugs that require long-term therapeutic effects with minimal side effects.
