Abstract:
Disclosed are polymers of hydroxypropyl methyl cellulose acetate succinate (HPMCAS) and hydroxypropyl methyl cellulose acetate (HPMCA) with unique degrees of substitution of hydroxypropoxy, methoxy, acetyl, and succinoyl groups. When used in making compositions comprising a low-solubility drug and such polymers, the polymers provide enhanced aqueous concentrations and/or improved physical stability.
