Naproxen Sodium is the sodium salt form of naproxen, a member of the arylacetic acid group of non-steroidal anti-inflammatory drugs (NSAIDs) with anti-inflammatory analgesic and antipyretic properties.Naproxen sodium reversibly and competitively inhibits cyclooxygenases (COX), thereby blocking the conversion of arachidonic acid to pro-inflammatory prostaglandins. To avoid this risk, a proton pump inhibitor is often prescribed along with it. ), wird als nichtsteroidales Antirheumatikum, Antiphlogistikum, schwach bis mittelstarkes… DSC thermogram of combination sample [Fig. 2007 Dec 15;365(1861):2799-812. doi: 10.1098/rsta.2007.0018.

Near-infrared (IR) spectroscopy is used for the rapid, nondestructive identification and quantitation of the hydrate form of drug compounds forming both single and multiple hydration states. C. Infrared … 33 Figure 3.10. Quantum chemical calculations using density functional theory (DFT) with functions LSDA, B3LYP, B3PW91, BPV86, mPW1PW91 and PBEPBE at various basis set levels (LANL2DZ, SDD, 3-21G, 6-31G, 6-311G and STO-3G) were performed. Download the identifier in a file. Absorption maximum: at 270 nm, 280 nm, 287 nm and 291 nm. The vibrational spectral analysis indicates the LSDA/3-21G level and LSDA/6-311G level are both better than the other methods at all the remaining basis sets. Infrared spectrophotometers are used for recording spectra in the region of 4000-650 cm−1 (2.5-15.4 µm) or in some cases down to 200 cm−1 (50 µm). 2915.90cm-1 1687.

Molecular weight: 230.2592. All spectra were acquired in Mid Infrared region . Attach a copy of the IR spectrum (see the last page of the Naproxen report form that follows).  |  Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that works by effectively blocking the body’s production of certain hormones known to synthesize prostaglandins and cause inflammation. Formula: C 14 H 14 O 3. The 5(a)] exhibited an endothermic peak in the range of 255-257 o C, which encloses the value of melting point reported for naproxen sodium. Spectrochim Acta A Mol Biomol Spectrosc. mNap = the melting enthalpy of naproxen (Jg-1) W = the weight fraction of naproxen in the preparation.
