Detailed Answer:
Hello Ma'am

After going through the medical details provided by you I understand your concern for your health and I would like to tell you that both the medicines belongs to ARB'S group of antihypertensive medication.

Both of these have some effect on kidney function and electrolyte balance however the down effect on kidney function is more with Irbesartan as compared to losartan which is considered to be relatively safe from kidney function point of view.

So its advisable to continue with losartan as you are already facing kidney issues.

I hope this information will be helpful.

Kind regards
