Intent. To guage the influence of co-administered cars on in vitro dissolution in simulated gastric fluid of crushed speedy release tablets as an indicator for prospective drug bioavailability compromise. Techniques. Launch and dissolution of crushed amlodipine, atenolol, carbamazepine and warfarin tablets ended up tested with 6 foods and drinks which are frequently Employed in the clinical placing as mixers for crushed prescription drugs (water, orange juice, honey, yoghurt, strawberry jam and water thickened with Easythick powder) in comparison to complete tablets. 5 business thickening brokers (Easythick Innovative, Janbak F, Karicare, Nutilis, Viscaid) at three thickness degrees were being tested for their impact on the dissolution of crushed atenolol tablets.
