Example text

Marketed drugs are frequently found helpful for disorders beyond the formal labeled indications. Part of the reason for this situation is the long and expensive process needed to produce sufficient data to obtain FDA labeling approval, which are estimated to cost as much as $300,000,000 to $1 billion. Frequently, there is not sufficient monetary incentive to warrant such expenditure, yet a compound is often found to be effective by researchers and clinicians in a given medical discipline. The FDA has taken the position that the individual physician is in the best position to determine whether a medication may be helpful for a specific patient based upon that physician's reading of the literature as well as clinical experience.

These effects will result in increased plasma drug levels due to both greater bioavailability (due to reduced first pass metabolism) and due to decreased clearance. Thus, dose adjustment is necessary and should be guided by TDM when possible. Cytochrome P450 Enzyme Inhibition In contrast to anticonvulsants and alcohol, drugs such as bupropion, fluoxetine, fluvoxamine, nefazodone, quinidine, paroxetine, and some antipsychotics can inhibit specific CYP enzymes (7, 11, 36, 37, 41, 42, 43 and 44). Thus, TCAs, certain BZDs, bupropion, some steroids, and antipsychotics can all have their metabolism inhibited by drugs such as fluoxetine.

That is the reason for the third variable in Eq. 1. Biological differences among patients can shift their individual dose–response curves, either reducing or enhancing the magnitude of the drug response and sometimes even altering its fundamental nature. This biological heterogeneity results from differences in diagnosis, genetics, gender, age, organ function, and the internal environment of the body ( 8, 9, 10 and 11). The last variable includes the presence of other drugs, which can interact pharmacodynamically or pharmacokinetically, with the drug of interest.
