Prescription drugs like Sovaldi, Humira, Epipen, Insulin, Cymbalta, and Ozempic/Wegovy cost significantly more in the U.S. than in other countries. Reasons for this disparity include lack of government price regulation, market exclusivity, high R&D costs, complex pricing structures, consumer willingness to pay, lobbying influence, global pricing strategies, and limited competition. The U.S. has not regulated prices due to its free-market system's success in producing breakthrough drugs and the pharmaceutical industry's economic importance. Government intervention, such as Medicare negotiating drug prices and capping costs, is becoming more common to address high drug prices.
