My Husband Is Almost 81 Years Old. He Has Had

My husband is almost 81 years old. He has had some problems getting his b/p regulated. He takes 5mg of amlodipine once a day, prazosin 5mg twice a day, and started taking hydralazine 25mg. 2 tablets twice a day in the past year and recently was increased to 2 tablets 3 times a day. I'm not sure if all this is agreeing with him. He also takes atorvastatin 10 mg at bedtime, metformin er 500mg in the morning and 1000mg. with supper. clopidogrel 75mg. once a day. Seems to me that's a lot for him and I've been trying to get him to see a cardiologist for a second opinion. What do you think?
