What is it: A Process Control Plan (PCP) is a summary of defect prevention and reactive detection techniques. The overall intent of the PCP is to control the product characteristics and the associated process variables to ensure capability (around the identified target or nominal) and stability of the product over time.
Various compounds can reduce the activity of enzymes. They may act in a variety of different ways, and indeed may be reversible or irreversible inhibitors of the enzyme. An irreversible inhibitor causes covalent modification of the enzyme, so that its activity is permanently reduced.
Protease inhibitors are metabolised by enzymes in the liver and can interact with other medications by speeding up or slowing down their processing in the body. Ritonavir, in particular, is a strong inhibitor of these liver enzymes and slows the processing of many other drugs.rotease inhibitors. Protease inhibitors block the activity of the protease enzyme, which HIV uses to break up large polyproteins into the smaller pieces required for assembly of new viral particles.
