Thanks for writing in to Healthcare Magic!
You can not exchange these medicines because they belong to different classes and there effects are not comparable. The antihypertensive medicines should be taken, increased or switched only in the supervision of your doctor. You need frequent BP assessment to see the response.
You should get telmisartan
prescribed by a family physician there and take it in the same doses.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
