What is a Prodrug Delivery System?

A prodrug delivery system refers to the strategic design of pharmacologically inactive molecules (prodrugs) that undergo in vivo transformation to release active drugs at target sites. Incorporating liposomes into prodrug systems allows for improved drug solubility, controlled release kinetics, targeted tissue delivery, and enhanced pharmacokinetic profiles. Liposome-based delivery platforms enable the encapsulation, protection, and programmable release of hydrophobic, hydrophilic, and amphiphilic prodrugs, making them particularly valuable for preclinical therapeutic research.

Supplementary Knowledges: Prodrug Delivery

What are prodrug approaches for CNS delivery?

Prodrug approaches for CNS delivery involve chemically modifying therapeutic agents to enhance their ability to cross the blood-brain barrier (BBB). Strategies include increasing lipophilicity, utilizing transporter-mediated targeting (e.g., LAT1, GLUT1), and designing enzyme-sensitive linkages that release the active drug specifically within the brain environment.

What is the prodrug method?

The prodrug method is a drug design strategy where an inactive or less active derivative of a pharmacologically active compound is administered to improve properties such as solubility, stability, permeability, or targeting. The prodrug is subsequently metabolized in vivo to release the active therapeutic agent at the desired site of action.

What are prodrugs for oral drug delivery?

Prodrugs for oral drug delivery are specifically engineered to enhance oral bioavailability by improving solubility, membrane permeability, or stability in the gastrointestinal tract. They are designed to withstand harsh gastric conditions and are enzymatically or chemically converted into the active drug after absorption into systemic circulation.
