I did liver test and i don't have hepatitis a, b, or c and my sgpt is 66(>45)plus i'm taking olmesartan 10mg+lercanidipine 20mg, is it due to medications?

Alcohol, fatty liver: Could be meds but just as likely this mild elevation in transaminase liver levels could be due to other things (like mild-moderate alcohol use, or fatty infiltration of liver). Fatty liver is more likely if there are elevated triglycerides or signs of Insulin resistance (low hdl, elevated triglycerides, obesity, or hga1c > 5.6). Can also be seen if associated sleep apnea.
