Pharm-Rx Nifedipine USP

Nifedipine contains NLT 98.0% and NMT 102.0% of nifedipine (C₁₇H₁₈N₂O₆), calculated on the dried basis. [NOTE—Nifedipine, when exposed to daylight and certain wavelengths of artificial light, readily converts to a nitrosophenylpyridine derivative. Exposure to UV light leads to the formation of a nitrophenylpyridine derivative. Perform the Assay and other tests in the dark or under golden fluorescent or other low-actinic light. Use low-actinic glassware.]
