Drugs are a consequence of their interaction with macrocellular components of the body. These interactions modify the function of the relevant component, thereby initiating the biochemical and physiological changes that characterize the response or reaction to the drug. We could not talk about pharmacodynamics without referring to receptors. Receptors are cellular structures that have a specific purpose and are activated by different substances, both natural and external to the body (drugs).
Therefore, medicines or pharmaceuticals never create new effects in the body, but merely enhance or inhibit existing effects . In other words, drugs E Commerce Photo Editing do not create effects, but rather they modulate functions of our body through affinity and the existence, or not, of their intrinsic activity with the receptors. Other specialties regarding pharmacology within pharmacology there are other specialties , apart from pharmacodynamics and pharmacokinetics: therapeutic pharmacology . It studies chemicals in relation to the immunological, biological, and behavioral states that influence disease. Neuropharmacology . It is the study of how drugs affect the central nervous system and the neural mechanisms that influence behavior. This term is very broad and encompasses many aspects of the nervous system.
From the manipulation of a single neuron to entire areas of the brain, spinal cord and peripheral nerves. Molecular pharmacology . It studies the biochemical and biophysical characteristics of the interactions between the drug and the organism. Pharmacogenetics. It is a recent study that evaluates how a person's body responds to certain drugs according to their genes. Since each individual's genes are different, the drug in question will also react in ways that are unique to each person, even if the differences are minimal. Why is pharmacology important? According to a 2008 centers for disease control and prevention study ,
