Combination therapy

In contemporary usage, the expression combination therapy most often refers to the simultaneous administration of two or more medications to treat a single disease, but the expression is also used when other types of therapy are used at the same time.

Conditions treated with combination therapy include tuberculosis, leprosy, cancer, malaria, and HIV/AIDS.

Combination therapy may seem costlier than monotherapies in the short term but causes significant savings: lower treatment failure rate, lower case-fatality ratios, slower development of resistance and consequently, less money needed for the development of new drugs.
