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.
An enzyme inducer is a type of drug that increases the metabolic activity of an enzyme either by binding to the enzyme and activating it, or by increasing the expression of the gene coding for the enzyme.Classic examples: barbiturates (phenobarbitone), antiepileptics and rifampin.arbamazepine is another enzyme inducer. By enzyme induction it can reduce efficacy of haloperidol and oral contraceptives. The majority of enzymes which are of industrial interest are inducible. Induced enzymes are synthesized only in response to the presence in the environment of an inducer.
