WebTranslations in context of "hypoglycaemic agents" in English-Arabic from Reverso Context: Heparin, hypoglycaemic agents and diuretics: Since Surgam is highly protein-bound, it is not recommended for co-administration with other highly protein-bound drugs such as heparin. Only the unbound fraction of the drug undergoes metabolism in the liver and other tissues. As the drug dissociates from the protein, more and more drug undergoes metabolism. Changes in the levels of free drug change the volume of distribution because free drug may distribute into the tissues leading to a decrease in plasma concentration profile. For the drugs which rapidly undergo metabolism, clearance is dependent on the hepatic blood flow. For drugs which slowly undergo m…
