Dexpanthenol and ascorbic acid ameliorate colistin-induced nephrotoxicity in rats.
Colistin is a potent antibiotic which is mainly preferred in the treatment of multidrug-resistant (MDR) gram-negative bacilli. However, due to the increased risk of acute kidney injury following its use, the clinical application is limited. This nephrotoxicity is known to be induced by oxidative stress and related inflammation. In this study on rats, potent antioxidants Dexpanthenol (DEX) and Ascorbic acid (Vit C) have been administered in combination with Colistin to find out whether they would weaken Colistin's nephrotoxic effects.. Inflammation biomarkers were studied with enzyme-linked immunosorbent assay (ELISA) kits, and oxidative stress biomarkers were studied with different photometric methods in blood and tissue samples taken after treatment with DEX and Vit C in rats with colistin nephrotoxicity. In addition, inflammation and necrosis in the kidney tissues were examined pathologically.. It has been observed in the serum and tissue samples that DEX and Vit C decrease oxidative stress and inflammation biomarkers, therefore acting as nephroprotective agents.. These compounds have been found to ameliorate the nephrotoxic effects of Colistin, which were demonstrated in the rats treated with Colistin, as well as the combinations.

Simultaneous determination of some water-soluble vitamins and preservatives in multivitamin syrup by validated stability-indicating high-performance liquid chromatography method.
HPLC stability-indicating method has been developed for the simultaneous determination of some water-soluble vitamins (ascorbic acid, thiamine hydrochloride, riboflavin-5'-phosphate sodium, pyridoxine hydrochloride, nicotinamide, D(+)-panthenol) and two preservatives (methylparaben and sodium benzoate) in multivitamin syrup preparation. Water-soluble vitamins, preservatives and their degradants were separated on Zorbax SB-Aq (C(18)) (250 mm x 4.6 mm, 5 microm) column at an ambient temperature. Combined isocratic and gradient elution was performed with a mobile phase consisting of 0.0125 M hexane-1-sulfonic acid sodium salt in 0.1% (m/v) o-phosphoric acid, pH 2.4-2.5 (solvent A) and acetonitrile (solvent B) at the flow-rate 1 ml min(-1). Starting with solvent A an isocratic elution was performed for 15 min, then the composition was changed to 85% of A and 15% of B during the next 20 min and it was constant for 5 min, then the composition was changed to 70% of A and 30% of B during next 15 min and it was constant for 5 min and finally was changed to 100% of A as at the beginning of the elution. Detection was performed with diode array detector at 210, 230 and 254 nm. Multivitamin syrup preparation was subjected to stress testing (forced degradation) in order to demonstrate that degradants from the vitamins, preservatives and/or product excipients do not interfere with the quantification of vitamins and preservatives. Typical validation characteristics: selectivity, accuracy, precision, linearity, range, limit of quantification and limit of detection were evaluated for vitamins and preservatives.

Intravenous nutrient therapy: the "Myers' cocktail".
Building on the work of the late John Myers, MD, the author has used an intravenous vitamin-and-mineral formula for the treatment of a wide range of clinical conditions. The modified "Myers' cocktail," which consists of magnesium, calcium, B vitamins, and vitamin C, has been found to be effective against acute asthma attacks, migraines, fatigue (including chronic fatigue syndrome), fibromyalgia, acute muscle spasm, upper respiratory tract infections, chronic sinusitis, seasonal allergic rhinitis, cardiovascular disease, and other disorders. This paper presents a rationale for the therapeutic use of intravenous nutrients, reviews the relevant published clinical research, describes the author's clinical experiences, and discusses potential side effects and precautions.
