Hi welcome to Health care magic forum. Your mother is 56 years old and using ZYLORIC100mg, ROSUVAT10mg, TELISTA-AM, GLYCOFEZ G1. so long and she is comfertable.
Whether a drug is appropriate or not depends upon whether the patient is comfertable with it or not. So the drugs are appropriate to your mother. What is left is maintenance. You should take her to the doctor periodically once every 1 or 2 months to have sugar and BP checked. Due to age and relative kidney
functions one may need alteration of dose or the drug may be necesory that you doctor will decide after examination.
Besides i advise her some diet recomendations as avoid taking more of salt, sugar, sweets, and fruits, junk foods, and oily foods.
Take more of green leafy vegetables , pulses, sprouts, egg, milk, meat, and dry fruits. Wishing for a continuing health to her and thanks for calling.
