My Father Takes Hydrocodon-acetaminophine For Pain, He Also Takes Amiodarone

My father takes hydrocodon-acetaminophine for pain, he also takes amiodarone HCL,and levetiracetam 500 mg, and lisinopril 10mg, and Atorvastatin 40mg, he had a brain injury in july and had to have blood drained from the brain, also broke his L2 and now has fractured L4. He has a terrible time going to sleep. The doctor gave him some medicine to help him sleep but it doesn't work. Is there anything in any of these medications he takes that could cause him to not be able to sleep?
