Dear Dr John,
All electrolyte imbalance follow one rule that is severity of clinical manifestation is dependent on the gradient of change rather than absolute value.
If the original baseline levels are not known a pottasium of 6.0 seems to be significant.
Looking forward for your inputs.
Regards,

How about a bit of provocation.
Let's assume that the K+ result is due to Valsartan. While K+ is outside the reference limit, does it matter?

Dear Mike,
Its an interesting query.Literature is quite varied but the conclusion is possibly all ARB have simmilar risk of hyperkalemia.
Is the patient diabetic? If not I think a different class of drug will be helpful.
Can you please send me the patient details.
regards
Sutirtha

Subject: Hyperkalaemia on ARB's
Hi all
I have been consulted about a patient with persistent moderate hyperkalaemia, (K+ running 5.8-6.2 mmol/L). Many of the usual suspects have been excluded, but she is on valsartan. ARBs cause hyperkalaemia less often than ACE inhibitors, but it is described as a side-effect and a change of Rx is being considered. Does anyone know whether an alternative ARB is worth trying, or if it is a class effect and we need to change to a different class of antihypertensive?
Thanks in anticipation,
Mike
