Was my father perscribed too many meds?

Patient: Hello. My father is 68 and was recently perscribed a higher dose of BP meds. His previous doctor has him on a fine amount, but since he gets nervous in the office his dosage was upped with a new doctor. He is now taking 240 MG of Cartia twice a day, two doses of 25MG Coreg daily, and Losartan Potasium 100-25MG Dydrochlothia 20 MG. Is this too much for him to take? He feels fine, but it may be unnecessary because at home his blood pressure was 20 points under what it was in the office. His pharmacist also told him to be wary of the high amount, the Cartia and Coreg mixed, but what do you think? Is this too much?
