Beschreibung

Salicylamide is less acidic (pKa 8.2) than other salicylic acid derivatives. Although poorly soluble in water, stable solutions can be formed at pH 9 through ionization of the phenolic group. It is absorbed from the GI tract on oral administration and is rapidly metabolized to inactive metabolites by intestinal mucosa, but not by hydrolysis. Activity appears to reside in the intact molecule. It is approximately 40 to 55% plasma protein bound, and it competes with other salicylates and acetaminophen for glucuronide conjugation, decreasing the extent of conjugation of these other drugs.

Chemische Eigenschaften

Salicylamide is a odorless white or slightly pink crystals. It is less acidic (pKa 8.2) than other salicylic acid derivatives. Although poorly soluble in water, stable solutions can be formed at pH 9 through ionization of the phenolic group.

Verwenden

salicylamide is an analgesic, fungicide, and anti-inflammatory ingredient used to soothe the skin. It is an aromatic amide.

Definition

ChEBI: The simplest member of the class of salicylamides derived from salicylic acid.

Allgemeine Beschreibung

Salicylamide, o-hydroxybenzamide, is a derivative of salicylicacid that is fairly stable to heat, light, and moisture. Itreportedly exerts a moderately quicker and deeper analgesiceffect than aspirin because of quicker CNS penetration. Its metabolismdiffers from aspirin, because it is not metabolized tosalicylic acid but rather excreted exclusively as the ether glucuronideor sulfate. Thus, as a result of lack of contributionfrom salicylic acid, it has a lower analgesic and antipyretic efficacythan that of aspirin. However, it can be used in place ofsalicylates for patients with a demonstrated sensitivity to salicylates.It is also excreted much more rapidly than other salicylates,which accounts for its lower toxicity. It is available inseveral nonprescription products, in combination with acetaminophenand phenyltoloxamine (e.g., Rid-A Pain compound,Cetazone T, Dolorex, Ed-Flex, Lobac) or with aspirin,acetaminophen, and caffeine (e.g., Saleto, BC Powder).

Air & Water Reaktionen

Salicylamide darkens on exposure to air. . Insoluble in water.

Reaktivit?t anzeigen

Salicylamide is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). Salicylamide may be sensitive to prolonged exposure to light.

Brandgefahr

Flash point data for Salicylamide are not available; however, it is probably combustible.

Clinical Use

Whereas salicylamide is reported to be as effective as aspirin as an analgetic/antipyretic and is effective in relieving pain associated with arthritic conditions, it does not appear to possess useful anti-inflammatory activity. Thus, indications for the treatment of arthritic disease states are unwarranted, and its use is restricted to the relief of minor aches and pain at a dosage of 325 to 650 mg three or four times per day. Its effects in humans are not reliable, however, and its use is not widely recommended.

l?uterung methode
