Which element is not required during formal marketing/sales for drugs?

The correct choice highlights that helping to call United Healthcare to add a drug is not a requirement during formal marketing or sales processes for pharmaceuticals. In the context of formal marketing and sales, activities generally focus on promoting the drug itself and providing relevant information to healthcare professionals and patients.

Providing detailed drug information, distributing marketing brochures, and conducting follow-up surveys are all standard practices aimed at educating stakeholders about the drug's benefits, side effects, and usage. They ensure that potential prescribers and patients have access to essential information for informed decision-making.

On the other hand, assisting in calling UHC for the purpose of adding a drug falls outside typical marketing and sales responsibilities. That task would typically involve more administrative or regulatory functions rather than direct marketing efforts.
