Reliable USP Analysis of Dexamethasone Tablets on the Hamilton PRP-1 Column
Dexamethasone, a highly potent corticosteroid, is used primarily to treat severe conditions, like allergic reactions, inflammation, autoimmune disorders, and certain types of cancers. Due to its potency, drug formulation must adhere to strict regulations. The United States Pharmacopeia mandates that the active pharmaceutical ingredient (API) must be within 90%–110% of the labeled amount.1 This is essential for limiting possible severe adverse effects, including acute psychosis, severe hyperglycemia, adrenal suppression, infection risk, and gastrointestinal perforation.2
The USP method takes into account confirmation of the API, potency, purity, and batch consistency. Hamilton has successfully performed the USP method for dexamethasone using the PRP-1, 5 μm 4.1 x 150 mm HPLC column, achieving good reproducibility, purity, and identity. The method was validated following the guidelines in USP General Chapters <621>, <1225>, and <1226>. Results show excellent correlation, with a linear regression coefficient of R2 = 0.9999. Testing results of the formulated 3 mg tablet were 101% of the labeled amount, confirming compliance with USP standards. Analysis of dexamethasone using PRP-1 from Hamilton Company is a great choice due to its long-standing record of consistency and excellence for over 40 years.
