Is Olmax Advisable For High Blood Pressure In A Diabetic?

I am 50 years old having diabetic and pressure. For my pressure I was taking Almong 5mg and my pressure is of 90-140. Recently my doctor prescribed Olmax 20 for my pressure. He gave reason for changing from Amlong 5 mg to Olmax 20 - it is especially for diabetic patients. Any suggestions Thanks in advance
