Product information
Aspirin, acetylsalicylic acid (Aspro, Empirin), was introducedinto medicine by Dreser in 1899.Aspirin occurs as white crystals or as a white crystallinepowder and must be kept under dry conditions. It is not advisableto keep aspirin products in the kitchen or bathroomcabinets, because aspirin is slowly decomposed into aceticand salicylic acids in the presence of heat and moisture.Several proprietaries (e.g., Bufferin) use compounds such as sodium bicarbonate, aluminum glycinate, sodium citrate,aluminum hydroxide, or magnesium trisilicate to counteractaspirin's acidic property. One of the better antacids is dihydroxyaluminumaminoacetate. Aspirin is unusually effectivewhen prescribed with calcium glutamate. The more stable,nonirritant calcium acetylsalicylate is formed, and theglutamate portion (glutamic acid) maintains a pH of 3.5 to5. Practically all salts of aspirin, except those of aluminumand calcium, are unstable for pharmaceutical use. Thesesalts appear to have fewer undesirable side effects and induceanalgesia faster than aspirin. A timed release preparationof aspirin is available. It does not appear to offer anyadvantages over aspirin, except for bedtime dosage.
