Mucoadhesive is a term typically used in pharmaceuticals to describe a substance or material that sticks to the mucus layer lining the mucous membranes. It plays a crucial role in controlling drug release and the duration of drug action after administration. Some synonyms for mucoadhesive include mucosal adhesion, bioadhesion, and mucoadhesion. Other related terms include bioerodible, which refers to a substance that dissolves or breaks down after being exposed to body fluids, and biodegradable, which describes a material that can be broken down by living organisms. Mucoadhesive agents are commonly used in drug delivery systems, such as transdermal patches and nasal sprays, to enhance drug absorption and prolong the therapeutic effect.
