Application
- Water-soluble tablet binders: suitable for wet or dry granulation and direct compression processes to improve the compressibility of granules.
- Film formers: used in permeable film coatings for tablets and sugar coatings to prevent cracking, reduce moisture sensitivity and provide good film adhesion, elasticity and hardness.
- Pore formers: used as a component of matrix materials used in taste masking and controlled release formulations.
- Solubilizers: used in solid dispersion processes to increase bioavailability and improve drug solubility.
Notice
Copovidone is generally considered nontoxic. However, taking too much by mouth may cause stomach upset. It shows no skin sensitization. Animal studies in rats and dogs have not shown significant toxicity at high dietary levels.
