My Age 70, stent fixed in 2014 ,ulcer bleeding happened two weeks before ,now taking the medicines aspisol 75 mg, flavedon Mr. 35 mg, ivabrad, obimet 500 mg, atorva 5 mg. He was taking clopidrogel before bleeding (more than 4 years) .then after bleeding treatment he changed to ecosprin 75 mg with the above medicines. Before 10 days Dr. prescribed aspisol 75 instead of ecosprin. When he took ecosprin ,the creatinine was 1.1 only. After 10 days the result shows 1.9 crt during aspisol intake. Is it because of medicines? All his past history shows normal crt only. Any difference is there between aspisol (chewable) and aspirin? It will create changes in creatinine?
