As rightly said by you, it takes some time to stabilise.
The maximum dose of losartan
is 100 mg. The maximum dose for atenolol
is also 100 mg.
50 mg of each is a good approach. Wait for another 2 or 3 days.
If the pressure is still high, add a third drug - HCTZ
(Hydro Chloro Thiazide) at a fixed dose of 12.5 mg - you may have to check your electrolytes - especially potassium. It may have very good response and you can try reducing the dose of atenolol.
Alternatively, you can add amlodipine
Your treating doctor will be the best person to advise and follow up...
