Takeaways

• 😀 Pharmacodynamics and pharmacokinetics are key concepts in pharmacology: Pharmacodynamics focuses on what the drug does to the body, while pharmacokinetics looks at what the body does to the drug.
• 😀 Receptors can be either active or inactive, and the binding of drugs to these receptors can produce a range of effects in the body.
• 😀 Agonists are substances that activate receptors to produce a cellular response, while antagonists block receptor activation without causing a response.
• 😀 Full agonists fully activate receptors, leading to a maximal response, while partial agonists produce a submaximal response, even when all receptors are occupied.
• 😀 Inverse agonists reduce the number of active receptors, counteracting the effects of the agonist.
• 😀 Competitive antagonists can be displaced by increasing the concentration of an agonist, while non-competitive antagonists bind irreversibly to receptors, preventing activation by agonists.
• 😀 Functional antagonists act on different receptors to produce opposing effects and counteract the action of another drug or agonist.
• 😀 Receptors are classified into ion channels, G-protein-coupled receptors, enzyme-linked receptors, and intracellular receptors, each with different functions in cellular processes.
• 😀 Potency refers to the amount of drug needed to produce a specific effect, while efficacy refers to the maximum effect a drug can achieve, regardless of dose.
• 😀 The therapeutic index is a measure of drug safety, with a higher index indicating a safer drug, and a lower index suggesting a smaller margin between effective and toxic doses.
