ABSTRACT A sensitive high-performance liquid chromatographic (HPLC) method is described for the determination of a new potent antihypertensive agent, TCV-116, and its two metabolites (M-I and M-II) in human serum or urine. After pre-treatment of the specimens, the analytes were determined using a column switching technique, except for the metabolites in urine which were determined by gradient elution mode HPLC. The quantitation limits for TCV-116, M-I and M-II were all 0.5 ng/ml in serum, and 0.5, 10 and 110 ng/ml in urine, respectively. The methods were applied to clinical trials of TCV-116.

    ABSTRACT: A high-performance liquid chromatographic method with photometric detection has been developed for the determination of five angiotensin II receptor antagonists (ARA II): Losartan, Irbesartan, Valsartan, and Candesartan cilexetil and its metabolite Candesartan M1. Reversedphase chromatography was performed at room temperature on a μBondapak C18 column; compounds were separated by gradient elution with mixtures of acetonitrile and 0.1 M acetate buffer, pH 4, at different flow rates. Detection was at 254 nm. Urine samples were purified by solid-phase extraction on C8 cartridges, a procedure enabling recoveries > 85% for all the drugs except Candesartan cilexetil (71%). The analysis time was less than 50 min, including extraction (chromatographic analysis lasted 25 min). Intra- and inter-day coefficients of variation for all the compounds were below 8% and the method was highly accurate (relative error,RE, usually ca 3%). The accuracy, precision, and sensitivity (limit of quantitation 0.4 μg mL−1) of the method were sufficient for application to the screening of these ARA II in spiked urine samples.

    ABSTRACT: Candesartan cilexetil is the prodrug of candesartan, an angiotensin II type 1 (AT1) receptor antagonist. Absorbed candesartan cilexetil is completely metabolised to candesartan. Oral bioavailability is low (about 40%) because of incomplete absorption. Plasma protein binding in humans is more than 99%. The volume of distribution in healthy individuals is 0.13 L/kg. CV-15959 is the inactive metabolite of candesartan. Candesartan that reaches the systemic circulation is mainly cleared by the kidneys, and to a smaller extent by the biliary or intestinal route. The apparent oral clearance of candesartan is 0.25 L/h/kg after a single dose in healthy individuals. Oral clearance (3.4 to 28.4 L/h) is highly variable among patients. No relevant pharmacokinetic drug-food or drug-drug interactions are known. The terminal elimination half-life remains unclear, but appears to be longer than the currently used range of 4 to 9 hours. Non-compartmental models do not appear to be appropriate for the analysis of candesartan pharmacokinetic data. A 2-compartment analysis revealed a much longer half-life of 29 hours using data from patients with hypertension. However, a further indepth analysis has never been performed. The concentration-effect relationship is unaffected by age. No gender or race differences have been shown in the effect or pharmacokinetics of candesartan. Renal function affects the pharmacokinetic profile of candesartan. For patients with creatinine clearances of >60 ml/min x 1.73m(2), 30 to 60 ml/min x 1.73m(2) and 15 to 30 ml/min x 1.73m(2), the elimination half-life is 7.1, 10.0 and 15.7 hours, respectively, at a dose of 8 mg/day. However, at 12 mg/day an accumulation factor of 1.71 was found. Thus, a maximum daily dose of up to 8mg appears suitable in patients with severe renal dysfunction. No significant elimination of candesartan occurs with haemodialysis. In patients with mild to moderate hepatic impairment, no relevant pharmacokinetic alterations have been observed. Dosages of up to 12 mg/day do not require precautions in patients with mild to moderate liver disease. Clinically effective dosages range between 8 and 32 mg/day. The response rate of monotherapy with candesartan in patients with hypertension increases with dosage, but never exceeds 60% at a daily dosage of 16mg of candesartan. Dosages up to 32 mg/day do not increase this response rate.

    ABSTRACT: The renin-angiotensin system (RAS) is frequently activated in patients with chronic liver diseases. Angiotensin-II (AT-II) has been suggested to play an important role in liver fibrogenesis. It induces hepatic stellate cell (HSC) proliferation and up-regulates the transforming growth factor beta(1) (TGF-beta(1)) expression via AT-II type 1 receptor (AT(1)-R) in vitro. The aim of the present study was to examine the in vivo effect of candesartan (CA), a clinically used AT(1)-R blocker (ARB), and perindopril (PE), an angiotensin-converting enzyme (ACE) inhibitor (ACE-I), on pig serum-induced liver fibrosis development in rats. The clinically available comparable doses of CA and PE significantly attenuated the fibrosis development. These inhibitory effects of PE and CA were also found in the on-going liver fibrosis model. The hepatic hydroxyproline and serum fibrosis markers were significantly suppressed by CA and PE treatment. Furthermore, the alpha smooth muscle actin (alpha-SMA) positive cells in number were markedly suppressed by CA and PE treatment. Similarly, the hepatic TGF-beta(1) protein and messenger RNA (mRNA) levels were significantly suppressed. Our in vitro study showed that AT-II increased the TGF-beta(1) mRNA expression in the activated HSCs, and this effect was totally blocked by CA. These results suggested that the RAS, especially AT-II and AT(1)-R interaction plays a pivotal role in liver fibrosis development through HSC activation. Because both CA and PE are widely used in clinical practice without serious side effects, these drugs may provide an effective new strategy for anti-liver fibrosis therapy.
