Tissue selectivity
Tissue Selectivity
Tissue selectivity (pronunciation: /ˈtɪʃuː sɪˈlɛktɪvɪti/) is a term used in pharmacology to describe the ability of a drug to affect certain tissues more than others.
Etymology
The term "tissue selectivity" is derived from the English words "tissue", meaning a group of similar cells that perform a specific function, and "selectivity", which refers to the quality of carefully choosing something or someone.
Definition
Tissue selectivity is a concept in pharmacology where a drug or other therapeutic agent is more effective in certain tissues than in others. This is often due to the drug's ability to bind to specific receptors or other targets in these tissues.
