Dofetilide blocks only the rapid K channels; this means that at higher heart rates, when there is increased involvement of the slow K channels, dofetilide has less of an action potential-prolonging effect. Sotalol is indicated for the treatment of atrial or ventricular tachyarrhythmias, and AV re-entrant arrhythmias.
Potassium iodide is an ionic compound which is made of the following ions: K + I −. It crystallises in the sodium chloride structure. It is produced industrially by treating KOH with iodine. [36] It is a white salt, which is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985.
Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [ 9 ] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
Potassium bromide (K Br) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US. Its action is due to the bromide ion ( sodium bromide is equally effective).
The term "vitamin K antagonist" is a misnomer, as the drugs do not directly antagonise the action of vitamin K in the pharmacological sense, but rather the recycling of vitamin K. Vitamin K is required for the proper production of certain proteins involved in the blood clotting process.
The thought was if there was a pill across the room and you even got remotely near it, it was going to cause you problems and you might overdose," Hardee said.
Rhino pills and other non-prescription supplements aren’t regulated by the U.S. Food and Drug Administration (FDA) like medications are, and there’s rarely much science to back their claims.
