Damage to the nervous system is a predicted adverse effect arising from injury to microtubule-operated axonal transport mechanisms. Paclitaxel, from the bark of the pacific yew (Taxus brevifolia), inhibits disassembly of microtubules and induces atypical ones. Docetaxel is a semisynthetic derivative. Inhibition of DNA and RNA synthesis (A).
6-Mercaptopurine results from biotransformation of the inactive precursor azathioprine (p. 37). The uricostatic allopurinol inhibits the degradation of 6- mercaptopurine such that co-administration of the two drugs permits dose reduction of the latter. Frequently, the combination of cytostatics permits an improved therapeutic effect with fewer adverse reactions.

 

In emergencies, such as hyperglycemic coma, it can be given intravenously (mostly by infusion because i. v. injections have too brief an action; plasma t1/2 ~ 9 min). With the usual subcutaneous application, the effect is evident within 15 to 20 min, reaches a peak after approx. 3 h, and lasts for approx. 6 h. Lispro insulin has a faster onset and slightly shorter duration of action.
Because they are poorly absorbed and poorly tolerated systemically, most imidazoles are suitable only for topical use (clotrimazole, econazole oxiconazole, isoconazole, bifonazole, etc. ). Rarely, this use may result in contact dermatitis. Miconazole is given locally, or systemically by short-term infusion (despite its poor tolerability).
