Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small.

This required increasing quantities of purified taxol, up to 600 g (21 oz), and in 1977 a further request for 7,000 lb (3,200 kg) of bark was made. In 1978, two NCI researchers published a report showing that taxol was mildly effective in leukaemic mice. [63] In November 1978, taxol was shown to be effective in xenograft studies. [64]
The therapeutic index (TI; also referred to as therapeutic ratio) is a quantitative measurement of the relative safety of a drug with regard to risk of overdose.It is a comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect. [1]
The then National Statistician, Dame Karen Dunnell, stated that legislation would help improve public trust in official statistics [13] (although the ONS already acted independently, as per its own published guidelines, the National Statistics Code of Practice, [14] which set out the key principles and standards that official statisticians ...

[1] Taxol is an important drug in the treatment of cancer but also expensive because the compound is harvested from a scarce resource, namely the ...
Taxoids are a class of derivatives from taxol, [1] that is, paclitaxel.They were developed for their anticancer chemotherapeutic properties. Taxoids are usually treated as synonymous with taxanes; for example, a major medical dictionary defines the two terms with the same definition phrasing, [2] and in another the phrasing varies slightly but conveys nearly identical meaning.
