Amazon Pharmacy customers in College Station, Texas, now can have prescription medications delivered by drone in less than 60 minutes at no additional cost. The company plans to expand drone delivery to other cities as a way to improve patient health outcomes.

"We're taught from the first days of medical school that there is a golden window that matters in clinical medicine," said Dr. Vin Gupta, the company's chief medical officer. "That's the time between when a patient feels unwell and when they're able to get treatment. We're working hard at Amazon to dramatically narrow the golden window from diagnosis to treatment, and drone delivery marks a significant step forward. Whether it's an infectious disease or respiratory illness, early intervention can be critical to improving patient outcomes."
