Parameter Conventional dosage form GRDDS
Toxicity Higher toxicity risk Lower toxicity risk
Patient compliance Lower level Higher level
Dose dumping Lower risk of dose dumping Higher risk of dose dumping if technology fails
Adverse effects Higher chances Chances are reduced due to fewer blood level peaks outside therapeutic range
Overall health care cost May be higher In spite of higher initial cost, overall treatment cost may be less due to improved therapeutic benefit, fewer side effects, reduced time for health care personnel to dispense and administer drugs and monitor patients
