A Practical Approach to Toxicological Investigations by Alan Poole, George B. Leslie

By Alan Poole, George B. Leslie

First released in 1989, this booklet recognizes that new medications, nutrients ingredients and different compounds have to be rigorously screened for poisonous side-effects. the majority of this research is dedicated to the sensible questions of 'what toxicological reports should still we perform?' and 'how may still we practice them?' Compounds which endure toxicity trying out might be with ease categorized as these that are meant for management to guy and people which aren't. the previous contain prescribed drugs for use medicinally or prophylactically and chemical substances that are further to our nutrients, beverages or drugs to enhance their balance, visual appeal or palatability. because it is on prescribed drugs that the main entire toxicological reviews are often played, this ebook has been directed basically in the direction of to toxicological evaluate of power new medicines. the foundations and method of toxicological evaluate of different sorts of compounds are basically related.

It might appear to make good scientific sense to run the studies of increasing duration sequentially so as to utilise thefindingsof a shorter study before designing a subsequent longer study. However, since patent protection of a drug is of limited duration (15-20 years) it is commercially important to exploit as much of the patent protected period as possible. Since, with many drugs, oncogenicity studies lasting two years or more will be necessary before marketing can begin, some telescoping of the sequence of toxicity tests is usually considered desirable.

All guidelines appear to place great emphasis on testing for neutralising antibodies since it is feared that the absence of a toxic effect may simply be due to the compound being 'neutralised' by antibodies. Dose levels: it is suggested that only two dose levels be used; one at the therapeutic level with the other ten times higher. ) It is recommended that the naturally occurring product should be included if possible as a control. Length of studies and parameters to be measured: recommendations for duration of exposure are not well formulated and contain general statements such as 'duration and route of administration should be similar to man'.

In cages containing several animals it is often useful to mark their fur to provide a quick and reliable way of identifying individuals during dosing and clinical observations. Such markings can be achieved quite simply in albino strains by using hair dyes such as Inecto (manufactured by Rapidol Ltd, London W7 2PP).
