Hypromellose , short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used in eye drops, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products.
The following is a list of chemicals published as a requirement of Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as California Proposition 65, that are "known to the state to cause cancer or reproductive toxicity" as of January 3, 2020. [1]
Toxic: danger of serious damage to health by prolonged exposure through inhalation and if swallowed R48/24/25 Toxic: danger of serious damage to health by prolonged exposure in contact with skin and if swallowed R48/23/24/25 Toxic: danger of serious damage to health by prolonged exposure through inhalation, in contact with skin and if swallowed
The Beers Criteria for Potentially Inappropriate Medication Use in Older Adults, commonly called the Beers List, [1] are guidelines published by the American Geriatrics Society (AGS) for healthcare professionals to help improve the safety of prescribing medications for adults 65 years and older in all except palliative settings.
However, is it my understanding that CAS numbers are only assigned to unique molecules. (Even different enantiomers have different CAS numbers.) If I am correct here then the statement "The CAS registry number of hydroxypropyl methyl cellulose is 9004-65-3." is incorrect (I expect 9004-65-3 is the CAS number of merely one form of HPMC).
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
It is essential to use age-specific normal reference values, as healthy infants and children usually have levels that would be considered elevated in adults. [4] Additionally, ALP levels are "not well defined" as of 2020, and can vary by sex and by racial group. [ 5 ]
