GLP1 mimetic drugs like Albiglutide, and the DPP4 inhibitor linagliptin. Recently there is talks about the safety of metformin in mild renal impairment. As all of us know metformin is currently contraindicated if the serum creatinine is above 1.4mg in men and even lower in women.
In these days we are treating a woman with a lactic acidosis induced by metformin in a pt with pulmonary acute infection , vomiting and diarrhea . General practitioners must be allerted about the risks linked to the use of metformin in pt with kidney failure even if the common idea is that metformin is not dangerous with a kidney function of 60 ml/min . But when a pt is affected by a pulmonay infection or by vomiting ? So we prefer Repaglinide that is excreted completely through bile .
