More Information

The term "capsular" is most frequently used in the biological and medical sciences to describe the outer, protective layers or envelopes that encase organs, tissues, or capsules of drugs. For example, the kidney has a fibrous capsular layer that surrounds and protects it. In modern medicine, capsular forms of medications are widely used for ease of swallowing and targeted release of the drug. Capsular structures are also commonly found in viruses, where they protect the genetic material inside, ensuring stability and functionality during transmission.
