The infusions and capsules contain palonosetron hydrochloride, [13] which is also a solid. The hydrochloride is easily soluble in water, soluble in propylene glycol, and slightly soluble in ethanol and isopropyl alcohol. [14] [17] The molecule has two asymmetric carbon atoms. It is used in form of the pure (S,S)-stereoisomer. [17]

Cimetidine was the prototypical histamine H 2 receptor antagonist from which later drugs were developed. Cimetidine was the culmination of a project at Smith, Kline & French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist that would suppress stomach acid secretion.
The citrate is the least expensive soluble (high bioavailability) oral magnesium salt available in supplements, with 100 mg and 200 mg magnesium typically contained per capsule, tablet or 50 mg/mL in solution. [26]
For instance the overall prevalence of hypermagnesemia was 3.0%, especially in males in Iran. High magnesium concentrations were typical in people with cardiovascular disease, and 2.3 mg/dL or higher values were associated with worse hospital mortality. [4]
Magnesium stearate is often used as an anti-adherent [3] in the manufacture of medical tablets, capsules and powders. [4] In this regard, the substance is also useful because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets; magnesium stearate is the most commonly used lubricant for ...
Treating the solution of different soluble magnesium salts with alkaline water induces the precipitation of the solid hydroxide Mg(OH) 2: Mg 2+ + 2 OH − → Mg(OH) 2. As Mg 2+ is the second most abundant cation present in seawater after Na +, it can be economically extracted directly from seawater by alkalinisation as described here above.
Mg + H 2 → MgH 2. Lower temperature production from Mg and H 2 using nanocrystalline Mg produced in ball mills has been investigated. [4] Other preparations include: the hydrogenation of magnesium anthracene under mild conditions: [5] Mg(anthracene) + H 2 → MgH 2. the reaction of diethylmagnesium with lithium aluminium hydride [6]
