OBJECTIVE To investigate inhibition of cellulose polymers against supersaturated felodipine crystallization.METHODS The research was performed by preparing supersaturated amorphous felodipine solid,and was carried out by measuring the solubility of felodipine.The types,added amounts,ionic intensity and viscosity of cellulose polymers were employed to assess the crystallization inhibition effect of polymers against the BCS II class drug felodipine.RESULTS HPMC E15 suggested the strongest crystallization inhi...
