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.

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.

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.

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

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

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 ...

Investigation of thioctic acid, magnesium stearate and pyridoxine hydrochloride compatibility

Česká a slovenská farmacie, 2020
To identify possible interactions of components in dosage forms, studies are usually carried out at the stage of pharmaceutical development. Such studies can predict compatibility of active pharmaceutical ingredients and excipients in order to optimize drug formulation and certain parameters of technological process. Compatibility of some components of

Amitriptyline-Related Peripheral Neuropathy Relieved during Pyridoxine Hydrochloride Administration

Drug Intelligence & Clinical Pharmacy, 1982
AMITRIPTYLINE, a tricyclic antidepressant, is widely used to treat depression.1,2 Several reports indicate that this drug can induce symptoms of peripheral neuropathy.3–7 In the following case, peripheral paresthesias developed during amitriptyline therapy and were controlled by administration of oral pyridoxine hydrochloride (HCl).

Pyridoxine Hydrochloride Treatment of Carpal Tunnel Syndrome: A Review

Nutrition Reviews, 2004
It has been hypothesized that idiopathic carpal tunnel syndrome (CTS) is a manifestation of vitamin B6 deficiency. Some claim that B6 supplementation can alleviate symptoms. Others argue that pain relief occurs because of vitamin B6's anti-nociceptive properties or because B6 supplementation addresses an unrecognized peripheral neuropathy.
