Pharmacology of anesthetics

Pharmacology of anesthetics involves studying how these drugs work to block pain and sensations during medical procedures. General anesthetics, which render a person unconscious, affect the brain by enhancing inhibitory signals or blocking excitatory ones, leading to a loss of awareness and pain sensation. They can be administered through inhalation or injection. Local anesthetics numb a specific area by blocking nerve signals. The safety and effectiveness of anesthetics depend on proper dosing and monitoring, ensuring patients remain pain-free while minimizing risks during surgery or other medical interventions.
