Reason. To evaluate the impact of co-administered cars on in vitro dissolution in simulated gastric fluid of crushed rapid launch tablets being an indicator for potential drug bioavailability compromise. Procedures. Release and dissolution of crushed amlodipine, atenolol, carbamazepine and warfarin tablets ended up tested with 6 foods and drinks that happen to be regularly used in the medical setting as mixers for crushed medications (water, orange juice, honey, yoghurt, strawberry jam and water thickened with Easythick powder) compared to full tablets.
