Spectrophotometric determination of pyridoxine hydrochloride

The Analyst, 1987
A spectrophotometric method is described for the determination of pyridoxine hydrochloride based on an oxidative coupling reaction with 4-aminoantipyrine in the presence of ammonium persulphate. The stable yellow colour obtained is measured spectrophotometrically at 420 nm.

Photosensitive dermatitis caused by pyridoxine hydrochloride

Journal of the American Academy of Dermatology, 1998
Few photosensitive reactions caused by pyridoxine hydrochloride have been reported. There have been no reports of detailed photosensitivity studies on patients who have developed photosensitivity from pharmacologic doses of pyridoxine. Two patients with pyridoxine photosensitivity are described.

VITAMIN B6 (PYRIDOXINE HYDROCHLORIDE) TOXICOSIS IN FALCONS

Journal of Zoo and Wildlife Medicine, 2016
This manuscript reports three independent accidental cases of vitamin (Vit) B6 toxicosis in gyrfalcons (Falco rusticolus) and peregrine falcons (Falco peregrinus) and a toxicology study that was conducted to characterize the clinical responses of gyrfalcons and gyrfalcon × peregrine falcons to a range of single intramuscular (IM) and oral (PO) doses of

Photoallergic Drug Eruption Due to Pyridoxine Hydrochloride

The Journal of Dermatology, 1996
AbstractPhotoallergy to vitamin B6 is very rare; only a few cases of contact dermatitis and one case of photosensitive dermatitis due to pyritinol have been reported. We report here the first case of photoallergy drug eruption due to pyridoxine hydrochloride.A 71‐year‐old man developed papulo‐squamous erythemata which were confined to sun‐exposed sites.

Photosensitivity from pyridoxine hydrochloride (vitamin B6)

Journal of the American Academy of Dermatology, 1996
We describe a 35-year-old female patient with photosensitivity due to pyridoxine hydrochloride (vitamin B6) in a multivitamin over-the-counter preparation. Photopatch and oral photochallenge tests using pyridoxine hydrochloride and UVA irradiation were positive. Larger doses for therapeutic use could cause photosensitivity.

Spectrophotometric determination of pyridoxine hydrochloride in pharmaceutical samples

The Analyst, 1988
A spectrophotometric method is described for the determination of pyridoxine based on the formation of an azo dye by the reaction between pyridoxine and diazotised p-nitroaniline followed by reaction of this azo dye with mercury(II) to form a stable complex. Minerals, sugars and several vitamins do not interfere when present in amounts usually found in

Subacute toxicity of pyridoxine hydrochloride in the beagle dog

Toxicology and Applied Pharmacology, 1978
Abstract Supplemental doses of 0, 50, or 200 mg of pyridoxine HCl/kg/day were administered po to three groups of dogs for an average of 107 days. Ataxia, muscle weakness, and loss of balance developed between 40 and 75 days of treatment in the group that received 200 mg/kg/day.

Spectrophotometric Determination of Tolbutamide, Thiamine Hydrochloride, and Pyridoxine Hydrochloride in Combination Products

Journal of Pharmaceutical Sciences, 1979
The first derivative curve is used for tolbutamide determination in unit-dose tablets and in combination products. The absorbance contribution from tablet excipient and coexisting components, thiamine and pyridoxine, is thereby nullified. The interference from tolbutamide during thiamine and pyridoxine determination is eliminated by solvent extraction ...

Response to pyridoxine hydrochloride in refractory anemia due to myelofibrosis

The American Journal of Medicine, 1978
Eleven of 14 patients with primary myelofibrosis were given a therapeutic trial with 250 mg of pyridoxine hydrochloride daily because of refractory anemia. The effect on the hemoglobin level and the hematocrit value was studied and compared to that in a group of untreated patients with the same degree of anemia.
