Film coating for tablets and caplets
View Patent ↗The present invention relates to novel coating compositions for application to solid dosage forms such as tablets or caplets, solid dosage forms coated with the composition, and methods of preparing said coating compositions.
1. A tamper-proof capsule comprising at least one capsule shell part and coated at least one core caplet, said core being coated with a coating composition comprising hydroxypropylmethylcellulose (HPMC) in an amount ranging from about 20% to about 40% by weight, hydroxypropylcellulose (HPC) in an amount ranging from about 40% to about 60% by weight, and polyethylene glycol (PEG) in an amount of about 20% by weight, all based on the weight of the coating composition, wherein the HPMC and HPC are present in a total amount of about 80% by weight of the coating composition.
2. The tamper-proof capsule of claim 1 , wherein the HPMC is present in an amount of about 20% and the HPC is present in an amount of about 60%.
3. The tamper-proof capsule of claim 1 , wherein HPMC is present in an amount of about 30% and the HPC is present in an amount of about 50%.
4. The tamper-proof capsule of claim 1 , wherein HPMC is present in an amount of about 40% and the HPC is present in an amount of about 40%.
