What is the Origin of Nicotine Pharmacology?

Nicotine was first isolated in the early 19th century, and the systematic study of its effects began shortly thereafter. The term pharmacology itself is derived from the Greek pharmakon (drug or medicine) and logia (study of). Modern nicotine pharmacology gained significant momentum with the rise of public health concerns regarding tobacco use, focusing on the molecule's interaction with the central and peripheral nervous systems.

What is the Mechanism of Nicotine Pharmacology?

Nicotine primarily acts as an agonist at nicotinic acetylcholine receptors (nAChRs) throughout the central and peripheral nervous systems. Activation of these receptors in the adrenal medulla triggers the release of epinephrine and norepinephrine, hormones that mediate the acute physiological stress response. Furthermore, chronic nicotine exposure can alter the hypothalamic-pituitary-adrenal axis, contributing to long-term endocrine and metabolic dysregulation, including changes in insulin sensitivity.

Nicotine Pharmacology

Meaning

Nicotine Pharmacology is the scientific study of the biochemical and physiological effects of nicotine, an alkaloid found in tobacco and other plants, on the human body, particularly focusing on its interaction with the nervous and endocrine systems. This field examines nicotine’s mechanisms of action, its addictive properties, and its influence on the secretion and action of hormones such as cortisol, catecholamines, and vasopressin. Understanding this pharmacology is crucial for managing addiction and assessing health risks.
