The price of Makena, a drug to prevent preterm birth, has increased dramatically from $20 per dose to $1500 per dose. If all eligible women received the drug, it would increase national healthcare costs by over $4 billion annually. However, the same compound has been available for years at a much lower cost. While the manufacturer claims the new price is reasonable given research and development costs, doctors and patients say the price increase is outrageous. The U.S. military has increased its attacks on Libyan government forces, now using low-flying attack aircraft designed to strike ground troops and supply lines.
