Dear Ms. Sravya
Thanks for writing to us.
It is true that a high creatinine
forbids some of the therapies useful in heart disease
(e.g. ACE inhibitor/ARB class of drugs.). It would have been better if you had mentioned the actual level if creatinine , potassium and What are the drugs which your doctor wants to give (or could not give). Most of the drugs can be given in patients of diabetes/hypertension
and thyroid disorder
A substitute for ACE inhibitor/ ARB class of drugs in such patients is a combination of ISDN/Hydralazine, which is available in India. But these are empirical suggestions in absence of details.
Feel free to discuss more.
