briefly review the existing information on herbal compounds which could
combat acetaminophen (paracetamol) toxicity. A careful perusal of literature
revealed that acetaminophen overdose not only damages liver but also the
kidney. Nevertheless, the kidney was badly ignored in studies aimed at
preventing paracetamol toxicity with herbal drugs. On account of such major
neglect, so far no herbal-paracetamol combination could be made. Milk thistly
is only well researched drug which appears as a suitable future candidate,
but its action towards the kidney must be studied. The importance of such
studies in the future is discussed. Key words: Acetaminophen/paracetamol, hepatoxicity,
Nephrotoxicity, Herbal Drugs/combination. INTRODUCTION Acetaminophen (Paracetamol: N-acetyl-p-aminophen) is an effective analgesic - antipyretic drug which is often used to treat pain and fever. Acetaminophen is available without prescription in many parts of the world (Goodman and Gilman 1996). The most serious adverse effect of acute overdose of acetaminophen is dose-dependent, potentially fatal hepatic necrosis (Thomas 1993) which may be associated with renal tubular necrosis (Goodman and Gilman 1996). The number of self poisoning suicides with acetaminophen has grown alarming in recent years (Goodman and Gilman 1996; Gyamlani and Parikh 2002). According to a study in USA paracetamol was found to be associated with more than 10, 00, 00 cases of poisoning, 56000 visits to emergency departments, 26000 hospitalization and 450 deaths a year (BMJ 2002). Also acetaminophen was the drug most commonly taken in United Kingdom (Howton et al 1997) causing substantial number of deaths (Bray 1993). Cases of overdoses of acetaminophen in India are also not uncommon (Sharka et al. 1999). The principal antidotal treatment is the administration of sulphydryl compound like N-acetyl-cysteine which act by replenishing hepatic stores of glutathione. This drug is effective only if given orally or intravenously within less than 10 hours after ingestion (Smilkstein et al 1988). BRIEF REVIEW OF EXISTING REPORTS In the past, several herbal compounds have also been screened to test their ability to reduce and / or nullify acetaminophen induced hepatotoxicity. These reports are given subsequently. It is of interest to mention here that only in two studies both liver and kidney were taken into consideration (Lee et al. 2002 and Bagchi et al. 2002) otherwise the kidney is badly ignored. However, quite earlier it was suggested that special caution should be taken in patients with liver and kidney disease while using paracetamol (Brzeznicka and Piotrowsi 1989).
