An Introduction to Drug Chemical Agents ;
There are many different types of drug chemical agents, which can be broadly divided into three categories: central nervous system (CNS) depressants, CNS stimulants, and hallucinogens.
CNS depressants are drugs that slow down the activity of the brain and the central nervous system. They include alcohol, barbiturates, benzodiazepines, and GHB. CNS depressants can be used to relieve anxiety, tension, and stress, and to produce sleepiness or a feeling of relaxation. CNS stimulants are drugs that increase the activity of the brain and the central nervous system. They include amphetamines, cocaine, and ecstasy. CNS stimulants can be used to increase alertness, energy, and activity, and to produce feelings of euphoria.
Hallucinogens are drugs that alter perception, mood, and thoughts. They include LSD, magic mushrooms, and PCP. Hallucinogens can cause users to see, hear, and feel things that are not really there.
Types of Pharmacology
There are many different types of pharmacology, but some of the most common include pharmacodynamics, pharmacokinetics, and pharmacogenomics.
Pharmacodynamics is the study of how drugs interact with the body to produce their effects. Pharmacokinetics is the study of how the body processes drugs, including how they are absorbed, distributed, metabolized, and excreted. Pharmacogenomics is the study of how genes affect a person’s response to drugs.
