Et prodrug er et legemiddel som er inaktivt i den formen som den tas. Når legemiddelet har kommet inn i kroppen omformes det til den aktive formen. Omformingen skjer ved at en del av legemiddelets kjemiske struktur forandres. A prodrug is a medication or compound that, after administration, is metabolized into a pharmacologically active drug.
Inactive prodrugs are pharmacologically inactive medications that are metabolized into an active form within the body.
Instead of administering a drug directly, a corresponding prodrug might be used . Lipophilic prodrug agents have been used to increase brain delivery of hydrophilic molecules.

It is not active in its ingested form. It has to be broken down by bacteria in the colon into two products . Upon absorption, the drug becomes activated. This process, called bioactivation, occurs by in vivo metabolism.
Solubility, permeability and metabolic stability screening services for prodrug DMPK research. Monitor for both inactive ( prodrug ) and active metabolite. The rationale behind administering prodrugs is to optimize absorption, distribution, metabolism, and excretion of these drugs.
Stoffwechselvorgänge in die aktive Wirksubstanz überführt wird. Depending on the substance, it may or may not possess intrinsic pharmacological activity of its own. So lässt sich die Aufnahme von schlecht absorbierbaren . Approximately of all drugs approved globally .

They stated that captopril and lisinopril are active drugs and listed other ACE inhibitors approved in the United States that are inactive prodrugs until metabolized in the liver. More information should be provided on this clinically . Historically the term pro-drug was first introduced by Albert (2) who used the word pro-drug or pro-agent to describe compounds which undergo biotransformation prior to exhibiting their pharmacological effects.
Albert suggested that this concept could be used for many different purposes. It summarizes current experiences and strategies for the rational design of prodrugs , beginning at the early stages of the .
