Document Summary
Patients often receive 20 drugs in hospital, such as anti-anxiety drugs, surgical drugs, maintenance drugs, and many more. Therefore, the risk of drug interaction is significant in hospitalized patients. Drug interactions can occur between over-the-counter drugs, prescription medications, and many more. The possibility of drug interaction goes up linearly as the number of drugs taken simultaneously increases. Elderly (>90 years old) experiences increased risk of drug interactions. Due to age, elderly tend to take a variety of medications for different problems. Some individuals have less active metabolic enzymes, thus unable to break down the drug as quickly or efficiently as when they were younger. Drug interaction can occur with two or more drugs can be beneficial or cause adverse effects. Less frequently, one drug can potentiate the effect of another one. There are many interactions between prescription and recreational drugs. Some recreational drugs interact with each other.
