    Notizen: Abstract Methods: We investigated the pharmacokinetics of quinine (Qn) following administration of a single oral dose of 600 mg Qn sulphate in six male Thai patients with a moderate degree of chronic renal failure (CRF), and six male Thai subjects with normal renal function. Results: The drug was well tolerated in both groups of subjects; no major adverse reactions were observed. A marked alteration in the pharmacokinetics of Qn was found in patients with CRF compared to healthy subjects; there were six signifiicant changes in the pharmacokinetic parameters. Absorption was delayed, but increased in CRF (tmax 4.5 vs 1.6 h, Cmax 6.17 vs 3.45 μg·ml−1). Total clearance was significantly reduced 0.94 vs 2.84 ml·min−1·kg−1, whereas Vz/f remained unchanged (1.82 vs 2.78 1·kg−1). This resulted in the increased values of AUC and prolongation of the t1/2z and MRT in the patients (AUC 181.5 vs 61.8 μg·min−1·ml−1, t1/2z 26 vs 9.7 h, MRT 36.4 vs 11.3 h). Median concentrations of plasma unbound fraction of Qn collected at 4 h after drug administration in patients and healthy subjects were 7.3 vs 9.8%, respectively.

    Notizen: Summary In view of its highly tissue-selective pharmacological properties (i.e., relatively pure antagonist in reproductive tissue with minimal agonist effects to nearly full agonist properties in bone and on cholesterol metabolism), terms used to define compounds with slightly related pharmacology (i.e., antiestrogen, partial estrogen agonist) do not adequately describe raloxifene's activity. Thus, raloxifene is distinct from agents such as tamoxifen (which does stimulate the uterus), or frank estrogen (which do not sufficiently antagonize estrogen's agonistic effects in reproductive tissue). In this regard, raloxifene and its pyrrolidine analogue, LY117018, (81) are the first representatives of a novel class of pharmacological agents, which we have termed “selective estrogen receptor modulator” (SERM). While we now have considerable evidence to distinguish estrogen recepto-mediated effects on bone from those on reproductive tissue, the precise mechanism for this tissue-specific mechanism remains an active area of investigation. Clearly, many important issues remain to be explored.
