Description

General description

Phenytoin is a well-known aromatic anticonvulsant which undergoes metabolism in the hepatic microsomal system. It finds its application as the most effective treatment available for seizure disorders. It belongs to the class of phenyl hydantoins compounds. It can hinder the unnecessary activity of the brain during seizures by bringing stability to the sodium channels, causing decreased electrical conductivity among brain cells.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Application

Phenytoin may be used as a pharmaceutical reference standard in the determination of the analyte in pharmaceutical formulations and combined dosage forms by electrochemical, spectrophotometric, and chromatographic techniques.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

Reduces incidence of grand mal seizures; appears to stabilize excitable membranes perhaps through effects on Na+, K+, and Ca2+ channels.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
