To investigate the stability of methacholine chloride in 0.9% sodium chloride solutions.Methacholine powder was mixed with diluent to a final concentration of 5 and 10 mg/ml. Duplicates of each admixture were divided and stored in glass vials at 25 degrees C, 4 degrees C and -20 degrees C for 12 months.

Determination of Methacholine Chloride by Ion-Pair High-Pressure Liquid Chromatography
Journal of Liquid Chromatography, 1982Abstract A method of analysis of methacholine chloride is presented, which is adaptable to other choline esters. The method uses ion-pair high-pressure liquid chromatography. Using 1-heptane sulfonic acid optically transparent at low UV wavelengths as the specific ion-pair, it was possible to assay for a specific choline ester using ultraviolet ...

Effect of methacholine chloride on rheology and transport of canine tracheal mucus
Journal of Applied Physiology, 1979The effect of methacholine chloride (M) on tracheal mucus was investigated in three conscious tracheostomized dogs. Aerosols of M in concentrations of 2--32 mg/ml were delivered intratracheally for 1 min. Mucus was sampled with a cytology brush at 2 min postchallenge and at irregular intervals thereafter.

Archives of Dermatology, 1960
In 1953, Lobitz and Campbell11described a strikingly abnormal cutaneous response in patients with atopic dermatitis. When acetylcholine and its derivative methacholine (acetyl-β-methylcholine; Mecholyl) were injected intradermally, a delayed blanch of the skin was seen at the site of injection. This was in marked contrast to the erythematous wheal that

Respiratory care, 2003
Current American Thoracic Society and American Association for Respiratory Care guidelines for the delivery of aerosol agents such as methacholine chloride (MC) for bronchoprovocation testing require the use of pneumatic jet nebulizers that have well-defined droplet size and mass output.

The American review of respiratory disease, 1983
Persons with hyperreactive airways differ quantitatively from normal persons in their response to bronchial provocation testing with methacholine chloride (Mch). Methacholine chloride has strong hygroscopic properties that necessitate careful dessication, preparation, and handling if accurate results are to be achieved. The rate of hydration of Mch was

Stability of stored methacholine chloride solutions: clinically useful information.
The American review of respiratory disease, 1982Methacholine inhalation challenge (MIC) has been shown to be an extremely useful diagnostic test. Because a decrease in the time and expense involved in the preparation of methacholine chloride solutions might encourage more laboratories to perform MIC, we assessed the stability of several different concentrations of methacholine chloride in solution ...

Arerugi = [Allergy], 2016
In abroad, Methacholine Chloride (Provocholine®) is used to meet the indications of the diagnosis of bronchial airway hyperreactivity in subjects who do not have clinically apparent asthma. We examined efficacy, safety and pharmacokinetics of Methacholine Chloride (name of study drug: SK-1211) in order to get approved for the airway hyperresponsiveness

The American review of respiratory disease, 1980
We compared simultaneously measured canine tracheal transport rates of Dowex anion exchange particles with macroaggregates of albumin, and with sulfur colloid. We found that sulfur colloid moved significantly faster than large Dowex particles (diameter 180 micrometer), which had transport rates similar to macroaggregates of albumin, and small Dowex ...
