Discuss the below in detail:
Q: Genentech, Inc., manufactures Protropin, a genetically engineered version of the human growth hormone. This drug's purpose is to enhance the growth of short children. Protropin is an important product for Genentech, accounting for more than one-third of the company's total revenue of $217 million. Although the drug is approved for the treatment of children whose bodies make inadequate quantities of growth hormone, many doctors prescribe it for children with normal amounts of growth hormone who simply happen to be short. There is no ?rm evidence that the drug actually increases growth for short children with normal growth hormone. Moreover, many people question whether it is appropriate to prescribe such a powerful drug for cosmetic reasons, especially when the drug may not work. Nor is there proof that it is safe over the long term. Is Genentech behaving ethically? Should it discourage doctors from prescribing the drug to normal, short children?
