👉 The selling fluid, often referred to as the "selling substance" or "conversion fluid," is a key component in the pharmaceutical sales process, particularly for injectable medications. It is a sterile liquid solution that facilitates the absorption of the active pharmaceutical ingredient (API) into the patient's bloodstream, thereby enhancing the drug's bioavailability and efficacy. This fluid typically contains preservatives, buffering agents, and other excipients to ensure the stability, safety, and proper delivery of the medication. By optimizing the absorption rate, the selling fluid can significantly improve therapeutic outcomes and patient compliance, making it an essential element in the successful marketing and administration of injectable drugs.
