Although EPO deficiency is the primary cause of CKD anemia, iron deficiency is often present, and it is essential to assess and monitor the CKD patient s iron status (NKF-K/DOQI guidelines). Iron stores in patients with CKD should be maintained so that transferrin saturation (TSAT) is greater than 20% and serum ferritin is greater than 100 ng/mL (100 mcg/L or 225 pmol/L). If iron stores are not maintained appropriately, epoetin or darbepoetin will not be effective, and most CKD patients will require iron supplementation. Oral iron therapy can be used, but it is often ineffective, particularly in CKD patients on dialysis. Therefore, intravenous iron therapy is used extensively in these patients. Details of the pharmacology, pharmacokinetics, adverse effects, interactions, dose, and administration of erythropoietin and iron products have been discussed previously.

The effects of perfluorinated compounds on prenatal and postnatal endpoints have been evaluated in rodents for PFOA, PFNA, PFDA, perfluorooctadecanoic acid (PFOcDA), the 8-2 FTOH, and an FTOH mixture and in mice for PFOA. PFOA is the best-characterized of these compounds, having been assessed in both rats and mice. Mice appear to be far more sensitive to the effects of PFOA on development compared to rats, possibly due to the aforementioned species difference in pharmacokinetics. Adverse effects noted prenatally in mice and/or rats with the above-cited compounds include decreased implantation/number of corpora lutea (mixed FTOH and PFOcDA), increased percent litter loss and/or incidence of full litter resorption (FLR) reduced skeletal ossification and/or increased incidences of skeletal variations and decreased fetal body weights (Abbott et al. 2007 Lau et al. 

Dtug interactions can cause serious problems in clinical practice especially when the affected dmg has the potential to be highly toxic. Furthermore, pharmacokinetic interactions are clinically important if the affected dmg has a narrow therapeutic range (i.e. small difference between the minimum effective concentration and the toxic concentration Fig. 1) and a steep concentration-response curve (i.e. significant alterations in pharmacological and/or adverse effects caused by small changes in blood concentration). 

Medications that have been used as treatment for anxiety and depression in the postwithdrawal state include antidepressants, benzodia2epines and other anxiolytics, antipsychotics, and lithium. In general, the indications for use of these medications in alcoholic patients are similar to those for use in nonalcoholic patients with psychiatric illness. However, following careful differential diagnosis, the choice of medications should take into account the increased potential for adverse effects when the medications are prescribed to alcoholic patients. For example, adverse effects can result from pharmacodynamic interactions with medical disorders commonly present in alcoholic patients, as well as from pharmacokinetic interactions with medications prescribed to treat these disorders (Sullivan and O Connor 2004). 

BEIs apply to 8 hr exposures, five days a week. However, BEIs for altered working schedules can be extrapolated on pharmacokinetic and pharmacodynamic bases. BEIs should not be applied, either directly or through a conversion factor, to the determination of safe levels for non-occupational exposure to air and water pollutants, or food contaminants. The BEIs are not intended for use as a measure of adverse effects or for diagnosis of occupational illness.

Vigilance for drug-drug interactions is required because of the greater number of medications prescribed to elderly patients and enhanced sensitivity to adverse effects. Pharmacokinetic interactions include metabolic enzyme induction or inhibition and protein binding displacement interactions (e.g., divalproex and warfarin). Pharmacodynamic interactions include additive sedation and cognitive toxicity, which increases risk of falls and other impairments.
