Combination therapy
Combination therapy or polytherapy is
Polypharmacy is a related term, referring to the use of multiple medications (without regard to whether they are for the same or separate conditions/diseases). Sometimes "polymedicine" is used to refer to pharmaceutical combination therapy. Most of these kinds of terms lack a universally consistent definition, so caution and clarification are often advisable.
Uses
Conditions treated with combination therapy include
Combination therapy may seem costlier than monotherapy in the short term, but when it is used appropriately, it causes significant savings: lower treatment failure rate, lower case-fatality ratios, fewer side-effects than monotherapy, slower development of resistance, and thus less money needed for the development of new drugs.[1]
In oncology
Combination therapy has gained momentum in oncology in recent years, with various studies demonstrating higher response rates with combinations of drugs compared to monotherapies,[2][3] and the FDA recently approving therapeutic combination regimens that demonstrated superior safety and efficacy to monotherapies.[4] In a recent study about solid cancers, Martin Nowak, Bert Vogelstein, and colleagues showed that in most clinical cases, combination therapies are needed to avoid the evolution of resistance to targeted drugs. Furthermore, they find that the simultaneous administration of multiple targeted drugs minimizes the chance of relapse when no single mutation confers cross-resistance to both drugs.[1]
Various systems biology methods must be used to discover combination therapies to overcome drug resistance in select cancer types.
The National Cancer Institute has recently highlighted combination therapy as a top research priority in oncology.[10]
Bacterial infections
Combination therapy with two or more antibiotics are often used in an effort to treat multi-drug resistant Gram-negative bacteria.[11]
Contrast to monotherapy
Monotherapy, or the use of a single therapy, can be applied to any therapeutic approach, but it is most commonly used to describe the use of a single

Monotherapy: The treatment of epilepsy with a single medication rather than a combination. Monotherapy has advantages over combining medications in many patients, including absence of drug-drug interactions, fewer side effects, simpler dosing, and lower cost. However, not all patients can be controlled with monotherapy.
