Cellulose hydroxypropylmethylcellulose phthalate

Ketoprofen (SIMS), hydroxypropylmethylcellulose E5 (HPMC, t =2%, 5mPas, Dow Chemical), glyceryl monostearate (Precirol, Gattefosse), Eudragit E 30 D (Rhom Pharma), Polyethylene glycol 400 (PEG 400, Merck) and cellulose acetate phthalate (CAP, Ambrochim) were used directly without any prior purification. [Pg.72]

The salt form of the polymer may also play a role in determining the performance of the formulation. Kane et al. [32] found that cellulose acetate phthalate was more effective than cellulose acetate trimellitate in controlling the dissolution of sulfothiazole-sodium tablets with cellulose acetate. The enteric properties of hydroxypropylmethylcellulose phthalate (HPMCP) were found to depend on the solubility of the drug that was coated. [Pg.21]
