Metadoxine is an ion pair salt of pyridoxine and pyrrolidone carboxylate (PCA). [1] Pyridoxine (vitamin B 6 ) is a precursor of coenzymes including pyridoxal 5’-phosphate (PLP), which accelerates the metabolic degradation of ethanol and prevents adenosine triphosphate (ATP) inactivation by acetaldehyde .
The carboxylate has a pKa of about 3.6 and is therefore negatively charged in solutions of pH greater than about 5.5. pH-sensitive vesicles can be prepared using this surfactant with another cationic or water-insoluble amphiphiles such as 1-decanol. [2] [3] [4]
Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
Calcium stearate is a carboxylate salt of calcium, classified as a calcium soap. The salt is a component of some lubricants , surfactants , as well as many foodstuffs. It is a white waxy powder.
Polystyrene sulfonates can bind to various drugs within the digestive tract and thus lower their absorption and effectiveness. Common examples include lithium, thyroxine, and digitalis. In September 2017, the FDA recommended separating the dosing of polystyrene sulfonate from any other oral medications by at least three hours to avoid any ...
It can cause a black tongue and black stools in some users of the drug when it combines with trace amounts of sulfur in saliva and the colon to form bismuth sulfide. [7] Bismuth sulfide is a highly insoluble black salt, and the discoloration seen is temporary and harmless. Long-term use (more than six weeks) may lead to accumulation and ...

Two popular drugs, often called alkanolamine beta blockers, are members of this structural class: propranolol, pindolol. Isoetarine is yet another medicinally useful derivative of ethanolamine. [citation needed]
