Hi I Am On 25 Mgs Of Losartan A Day.

Hi i am on 25 mgs of Losartan a day. I take half in the morning and the other half in the evening.
As my heart rate is around the 100 to 110 mark my Dr put me on 5 mgs concor in the morning. I am a male 67 year old. My bp on meds is around 110\67 and pulse is now better on concor and around 70 to 90 bpm.
I take the concor at 10 am the losartan at 2 pm and again at 6pm.
My question is can i take concor and losartan together at 10am and the other half losartan at 10pm?
Thank you in advance. David YYYY@YYYY
