yeah..looks like A

going backwards- amitryptyline reduces amine reuptake in depression./// phenylephrine is the alpha 1 agonist that decreases H.R.////tobutamide is a 1st generation diabetic med that blocks K+ channel , depolarizes and causes some insulin release/// thalidomides is teratogenic that most docs will stay far away from due to legal problems.{i think the word phocomelia is used} **Theophyline the answer comes under the category methlxanthine known for arrythmias and CNS stimulation
