100,000 hospitalizations a year caused by four drugs

A study by researchers from the US Centers for Drug Control and Prevention has linked the majority of hospitalizations to four drugs: warfarin, oral antiplatelet medications, insulins, and oral hypoglycemic agents. A majority of these hospitalizations are due to allergic reactions and accidental overdoses, and 48.1 percent were 80 years old or older.

The study has also shown that better management of related drugs could potentially lead to the avoidance of thousands of hospital admissions.
