Timepidium bromide (INN) is an anticholinergic. It is used in the symptomatic treatment of visceral spasms. [1] It is also used to relieve pain associated with various gastrointestinal disorders. [2] The quaternary nitrogen prevents it from crossing the blood brain barrier, so it is peripherally acting with no central side effects.

The same compound sans the quaternary methyl group and the methoxy ether is called tipepidine. [3]

A graphics tablet is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper that is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear polylines or shapes, is called digitizing.

<span class="mw-page-title-main">Glycopyrronium bromide</span> Chemical compound

Glycopyrronium bromide is a medication of the muscarinic anticholinergic group. It does not cross the blood–brain barrier and consequently has few to no central effects. It is available in oral, intravenous, topical, and inhaled forms. It is a synthetic quaternary ammonium compound.

A bromide ion is the negatively charged form (Br) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. Although uncommon, chronic toxicity from bromide can result in bromism, a syndrome with multiple neurological symptoms. Bromide toxicity can also cause a type of skin eruption, see potassium bromide. The bromide ion has an ionic radius of 196 pm.

Cetrimide, or alkyltrimethylammonium bromide, is an antiseptic which is a mixture of three quaternary ammonium compounds: tetradonium bromide, cetrimonium bromide (CTAB), and laurtrimonium bromide. It was first discovered and developed by ICI and introduced under the brand name Cetavlon. It is used as a 1-3 % solution for cleaning roadside accident wounds. ICI also introduced Savlon, which was a combination of cetrimide and chlorhexidine. ICI later sold the Savlon brand OTC to Johnson & Johnson in May 1992. Cetrimide is used in various applications such as antiseptic agents, diagnostic test and analysis, topical formulations, and dental treatment.

<span class="mw-page-title-main">Ketobemidone</span> Chemical compound

Ketobemidone, sold under the brand name Ketogan among others, is a powerful synthetic opioid painkiller. Its effectiveness against pain is in the same range as morphine, and it also has some NMDA-antagonist properties imparted, in part, by its metabolite norketobemidone. This may make it useful for some types of pain that do not respond well to other opioids. It is marketed in Denmark, Iceland, Norway and Sweden and is used for severe pain.

<span class="mw-page-title-main">Methylnaltrexone</span> Medication in the treatment for Opioid-Induced Constipation

Methylnaltrexone, used in form of methylnaltrexone bromide, is a medication that acts as a peripherally acting μ-opioid receptor antagonist that acts to reverse some of the side effects of opioid drugs such as constipation without significantly affecting pain relief or precipitating withdrawals. Because MNTX is a quaternary ammonium cation, it cannot cross the blood–brain barrier, and so has antagonist effects throughout the body, counteracting effects such as itching and constipation, but without affecting opioid effects in the brain such as pain relief. However, since a significant fraction of opioid analgesia can be mediated by opioid receptors on peripheral sensory neurons, particularly in inflammatory conditions such as arthritis, traumatic or surgical pain, MNTX may increase pain under such circumstances.
