Drug antagonism is a phenomenon in pharmacology where one drug interferes with the activity or effects of another drug. This can occur in several ways, such as by blocking the receptor that the other drug acts on, by inhibiting the enzyme responsible for metabolizing the other drug, or by disrupting the signaling pathways involved in the other drug's effects. Antagonism can lead to reduced effectiveness or complete inhibition of the other drug's actions, potentially resulting in decreased therapeutic effects or negative side effects.
