A drug-drug interaction may increase or decrease the effects of one or both drugs. Adverse effects or therapeutic failure may result. Rarely, clinicians can use predictable drug-drug interactions to produce a desired therapeutic effect. For example, coadministration of lopinavir and ritonavir to patients with HIV infection results in altered metabolism of lopinavir and increases serum lopinavir concentrations and effectiveness. Concurrent use of another drug that increases the action of these drugs further increases risk of adverse effects. For additional research on potential drug-drug interactions, consult a reliable source, such as Drug.

It is important to know the possible drug interactions as these can cause serious adverse reactions or result in failed therapy. Drug-drug interactions result when two or more drugs react with each other. Drugs with a narrow therapeutic range little difference between therapeutic and lethal dose are more likely to face incidents of serious drug interactions. For example: Taking digoxin with antibiotics like erythromycin or clarithromycin will increase the toxicity of digoxin because antibiotics affect the liver enzymes, causing digoxin to be metabolized inactivated slower. Similarly, the concurrent use of methotrexate and ibuprofen may result in increased methotrexate toxicity due to inhibition of kidney excretion by ibuprofen. The effectiveness of drugs may be reduced in situations where the action of one drug diminishes the action of the other.

Drug interactions can have desired, reduced or unwanted effects. The probability of interactions increases with the number of drugs taken. The high rate of prescribed drugs in elderly patients year-old patients take an average of 5 drugs increases the likelihood of drug interactions and thus the risk that drugs themselves can be the cause of hospitalization. Drug interactions occur on pharmacodynamic and pharmacokinetic levels. Examples of pharmacodynamic interactions are simultaneous administration of a NSAID and phenprocoumon additive interaction , or of aspirin and ibuprofen antagonistic interaction.

Concepts in Biochemical Pharmacology pp Cite as. Drugs may frequently interact adversely to cause drug toxicity or render a needed therapy ineffective. The situation is compounded by the current pattern of drug usage in which approximately ten different drugs are received by the average patient in the hospital.

For example, patients with epilepsy have increased chances of drug interaction, compared with those with other disease states. Thus, there is little room for error when using these drugs. Compromised renal function or changes in the cytochrome P enzymes also can increase the risk of experiencing a severe adverse drug event. Clearly, it is important for pharmacists to recognize and understand which drug interactions can result in significant patient harm.
