Dear patient, I do not see any ACE inhibitor or ARBs in your therapy. It is a good drug in order to reduce the progression of renal disease ( but also any cardiovascular disease). You can ask your physician to start with ramipril, 2.5 mg once a day and increase at the maximum tolerated dose ( 10 mg). It can be an excellent substitute of minoxidil. You can expect a transient increase of serum creatinine but it has been demonstrated that renal survival, at the long term, will increase. Your physician should strictly follow serum potassium at least for the first month s of treatment, since potassium can be found higher than normal and it may be cause of severe hyperkalemia.
