Hi, I am 41 years old male that has been diagnosed with high blood pressure 20 years ago approxemately 160/90. Since 1991 I was on Atenolol, Tenormin 50mg once a day. Since 2009 I stopped the Atenolol, Tenormin 50mg and I am on 80mg Micardis once a day. Today, I visited my public hospital and the pharmacist informed me that instead of Micardis 80mg they replaced it with another medicine called Losartan 50mg.
If I switch from Micardis to Losartan, what is the difference between them and what is the best medicine between them, for example which of them has lower side effects, etc ?
Which is the newer medicine between them and if for example, one of the two is newer that the other, then what is the role of this factor, any improvement between them, etc..?
