In the opioid segment, which drug is highlighted as selling more per year than Viagra?

• A. OxyContin
• B. Vicodin
• C. Percocet
• D. Fentanyl

Answer: (A)

In this context, sales volume and revenue are driven by how widely a drug is prescribed, how much it costs, and how long it stays on the market. OxyContin earned the highlight because its long-acting opioid formulation led to very high annual sales, often surpassing Viagra in those years. Viagra, while a top seller in its own right as a treatment for erectile dysfunction, didn’t reach the same level of yearly revenue as the leading opioid in the data referenced. The other opioids listed are strong sellers too, but the data pointed to OxyContin as exceeding Viagra in annual sales, illustrating how prescribing trends and pricing can push one drug’s yearly revenue above another’s even when both are well-known products.
