Detailed explanation-1: -A condition that occurs when the body gets used to a medicine so that either more medicine is needed or different medicine is needed.
Detailed explanation-2: -Following repeated exposure, the effects of a drug can either be unchanged, lessened, or increased. When a drug’s effects are diminished following exposure to it, the change is called tolerance, when they are enhanced the change is called sensitization.
Detailed explanation-3: -Generally, tolerance leads to increasing doses of a drug being required to produce the same effect. Other possible mechanisms are a decrease in binding affinity between a drug and receptor and a decrease in the number of receptors. The mechanisms responsible for drug tolerance are not always known.
Detailed explanation-4: -Cross-tolerance could occur. This is tolerance to other drugs in the same class. With certain classes of drugs, like opioids, tolerance can increase the risk of dependence, addiction, and overdose. When your body develops tolerance, using higher doses increases the risk of overdose.
