Crushing and mixing any from the 4 medications with thickened drinking water prompted a substantial hold off in dissolution. When tested with atenolol, all types of thickening brokers on the greatest thickness noticeably restricted dissolution, and items that are generally according to xanthan gum also delayed dissolution with the intermediate thickness amount. Conclusions. Dissolution testing, although simplistic, is usually a extensively utilised and recognized technique for comparing drug launch from distinctive formulations as an indicator for in vivo bioavailability. Thickened fluids possess the probable to retard drug dissolution when employed within the thickest concentrations. These results highlight prospective scientific implications in the addition of these agents to medicines for the goal of dose shipping and point out that even further investigation of thickened fluids and their probable to affect therapeutic outcomes is warranted.
