The possibility of using high viscosity grades of hydroxypropylmethylcellulose (HPMC) as a film forming agent in a conventional coating process has been investigated. Ethanol/water mixtures having different weight ratios (5 to 18) and containing up to 5 % of HPMC revealed to be suitable. The influence of some formulation additives (talc, PVP and plasticizers) on both the overall coating process and the in-vitro release profiles of ketoprofen containing coated tablets was also investigated and discussed.
