The object of the investigation was to study the capacity of the liver to metabolize drugs under diversified conditions (cirrhosis, hepatitis, cholestasis in alcoholics, in diabetics as well as in eplieptics treated with barbiturates) as well as the possibility of inducing this function. To accomplish this we determined the half-life of Butazolidin. Only in cirrhotics it was shown that the capacity to metabolize Butazolidin was reduced. Induction with barbiturates increased hepatic captation of the drug but did not modify the biotransformation of the same. This is attributed to the development of a "hypoactive hypertrophy" of the reticuloendothelium.

The extended prescription of non-steroidal anti-inflammatory drugs in medical practice involve numerous adverse effects. Among them, hepatic injuries, rather uncommon, are very diverse with regard to clinical type and evolution scheme, according to the derivatives used. Salicylates, when taken at high doses, increase serum transaminases, mostly without overt clinical symptoms. Phenylbutazone is obviously hepatotoxic: it induces cytolytic hepatitis, in some cases with fatal issue. Among the indole derivatives, indometacine was involved, especially in children; mixed hepatitis have been noted during sulindac therapy, mostly with favourable outcome. In the group of propionic acid derivatives, ibuprofen, pirprofen and naproxen have been implicated in hepatitis of various types; ibufenac and benoxaprofen were quickly retired after occasioning several deaths. Concerning others non-steroidal anti-inflammatory drugs, some cases have been reported with piroxicam and diclofenac. Hepatotoxicity mechanisms are often unknown; they appear different according to each drug. Besides, the rheumatic disease under treatment and pharmacokinetic particularities (sulindac, diclofenac) might be important in this view. Monitoring of serum hepatic-enzyme concentrations seems recommended for patients receiving non-steroidal anti-inflammatory for long time therapy.

A 16-year-old pony with signs of intermittent abdominal pain was treated with phenylbutazone in excess of the recommended dosage. Endoscopy revealed ulceration of the esophagus, stomach, and proximal portion of small intestine. The pony developed diarrhea. Salmonella typhimurium was isolated from the blood and feces. Treatment included fluids, trimethoprim-sulfadiazine, sucralfate, and ranitidine hydrochloride. The diarrhea resolved, as did the gastrointestinal ulceration. This case was unusual because septicemia with salmonellosis is an uncommon finding in adult equids. Also, complications commonly seen in neonatal septicemia (septic arthritis, nephritis, and hepatitis) were not observed. Phenylbutazone toxicosis and stress were considered possible causes for the gastrointestinal ulceration.

1 Hepatotoxicity is rare when mild analgesics are used in normal therapeutic doses. 2 The potential of aspirin and salicylates to cause hepatotoxicity has been only recently recognized. 3 Salicylate hepatitis is often asymptomatic, and may only be revealed by finding elevated levels of aminotransferases. 4 Most cases have occurred in children or young adults with connective tissue diseases, who take high doses of salicylates for long periods. 5 Hepatic injury is not recognized as a complication of acute aspirin poisoning. 6 Following overdosage of paracetamol, a toxic intermediate metabolite causes acute hepatic necrosis which may be fatal. 7 Cysteamine, methionine and N-acetylcysteine confer protection against this severe liver damage, but the time between overdosage and treatment is critical. 8 The chronic therapeutic use of paracetamol should be considered a potential but very rare cause of active chronic hepatitis. 9 There is no clear evidence of phenacetin hepatotoxicity in man. 10 Phenylbutazone may cause liver injury and other analgesics can cause hypersensitivity reactions in which the liver is involved.
