Disturbances of acid-base equilibrium in salicylate intoxication.

The uricosuric activity of phenylbutazone, probenecide and sulphinpyrazone is strongly antagonized by salicylate and maybe completely diminished by small doses due to decreased tubular reabsorption of uric acid (Insel, 1996).

The loss of buffering capacity and the effects of salicylate on carbohydrate, lipid and protein metabolism lead to the development of a metabolic acidosis or, more commonly in practice, a mixed acid-base disturbance (Proudfoot & Brown, 1969; Meredith & Vale, 1981; Proudfoot, 1983).

Salicylic acid (PIM 642) - INCHEM

The dyes industry was also in the forefront in asserting intellectual property rights. Favorable patent laws play important roles in the pharmaceutical and life science industries; witness the recent scramble to patent human genes. However, they did not benefit aspirin. Bayer settled for registering a trademark for the name Aspirin. It did not patent acetylsalicylic acid, not because it would not but because it could not. The chemical was old stuff, synthesized by French chemist Charles Frederic Gerhardt back in 1853.

He also synthesized Aspirin because his father, who had severe arthritis, could not tolerate the salicylic acid he was taking for pain relief.
