A client calls the office to ask a question regarding his animal's medication. He is currently giving his dog one antibiotic tablet twice a day to treat a skin infection. The client is planning on going on vacation and is wondering if his dog sitter could give four antibiotic tablets once every two days instead of one antibiotic tablet four times over two days. Because the total dose over the two
days would be the same, the client thinks that this would save the dog sitter some time and trouble. Is it recommended for this dog to receive its entire two-day dose at one time? Why or why not? Relate your answer to testing or test results performed by drug companies to get FDA approval. What will be an ideal response?
