Description

General description

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.
Desloratadine is one of the orally active, highly selective peripheral H₁ receptor antagonists that does not exert any significant effect on the central and autonomic nervous systems. The potency of desloratadine is more than that of loratadine and it exhibits substantial overall pharmacological profile.

Application

Desloratadine may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and plasma samples by various chromatography 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

Desloratadine is a selective and nonsedating histamine H1 receptor antagonist, an active metabolite of loratadine (Claritin), used to relieve hay fever and allergy symptoms with less drowsiness than other antihistamines; does not significantly inhibits cardiac K+ channels at clinically achievable blood levels. Free from antimuscarinic/anticholinergic effects.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP 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.
