The Doherty Effect refers to a phenomenon in which the effectiveness of a drug or treatment is influenced by the presence of another substance. This effect is particularly relevant in pharmacology, where interactions between medications can enhance or diminish their therapeutic effects. Understanding this interaction is crucial for optimizing treatment plans and ensuring patient safety. This effect is named after Dr. John Doherty, who studied the interactions between various drugs. It highlights the importance of considering all substances a patient is taking, including over-the-counter medications and supplements, to avoid adverse effects and improve overall treatment outcomes.
