Drug

Meaning

A drug is defined clinically as any substance, other than food or water, which, when administered, is intended to affect the structure or function of the body, primarily for the purpose of diagnosis, cure, mitigation, treatment, or prevention of disease. These agents exert their effects by interacting with specific biological targets, such as receptors, enzymes, or ion channels, to elicit a desired physiological response. In the hormonal health space, drugs range from complex synthetic pharmaceuticals to bioidentical hormones used to correct endocrine deficiencies or imbalances. Precise dosage and delivery methods are critical to achieving therapeutic benefit while minimizing adverse reactions.
