CAIRO—When customers walk into Ahmed Ali’s pharmacy here, they often walk out without the medicine they need. He has run out of nearly a dozen prescription drugs for common ailments like high blood pressure and osteoporosis.
“Every day I have to say that something isn’t available,” said Mr. Ali, 26, whose patients are flying to Turkey or the U.K. to get medicine, if they can afford the flight. Those who can’t turn to a growing black market for prescription drugs.
