More research in pharmacology deals with identifying and responding to drug interactions and its side effects along with its mechanism of action, its therapeutic index and thereby treat accordingly. More intensive study with the interaction between Pediatrics drug and its therapeutic effect helps to identify the properties of ideal Pediatrics drugs.
