Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline.When you take beta blockers, the heart beats more slowly and with less force, thereby reducing blood pressure.eta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure.

Xylitol is naturally found in low concentrations in the fibers of many fruits and vegetables, and can be extracted from various berries, oats, and mushrooms, as well as fibrous material such as corn husks, sugar cane bagasse, and birch.ylitol is a  tooth-friendly , nonfermentable sugar alcohol. It appears to have more dental health benefits than other polyalcohols. The structure of xylitol contains a tridentate ligand, (H-C-OH) 3 that can rearrange with polyvalent cations like Ca 2+ .
Sorbitol, also known as glucitol, is a sugar alcohol with a sweet taste which the human body metabolizes slowly.It can be obtained by reduction of glucose, changing the aldehyde group to a hydroxyl group. Most sorbitol is made from corn syrup, but it is also found in apples, pears, peaches, and prunes.It is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase.Sorbitol is an isomer of mannitol, another sugar alcohol; the two differ only in the orientation of the hydroxyl group on carbon 2. While similar, the two sugar alcohols have very different sources in nature, melting points, and uses.orbitol often is used in mouthwash and toothpaste. Some transparent gels can be made only with sorbitol, as it has a refractive index sufficiently high for transparent formulations. It is also used frequently in sugar free chewing gum.
