ABSTRACT Gas chromatographic, mass fragmentographic and liquid chromatographic techniques for the determinations of bromocriptine (2-bromo-alpha-ergocriptine; Parlodel) in human plasma are described. These methods were found to be suitable for determining concentrations of bromocriptine down to 0.5, 1.0 and 10.0 microgram/l, respectively. Accuracy, specificity and analytical capacity were satisfactory for all three methods. Gas chromatography was compared with liquid chromatography, and the two methods were demonstrated to give identical results in patients treated with bromocriptine for Parkinson's disease. Gas chromatography was also compared with mass fragmentography, and the results from these two assays were also in agreement.

    ABSTRACT: The plasma kinetics of bromocriptine (BCT), a long-acting dopamine agonist, was studied in twelve patients with Parkinson's disease, using a newly developed gas chromatographic method of analysis. Each patient received BCT for at least three weeks in a constant but different dose regimen. Concomitant treatment with 1-DOPA was not allowed. During a 6-day hospitalization period, a blood sample was taken immediately before the afternoon dose at 14.00 h (Cmin) to determine the steady-state level. On the 6th day blood samples were collected every hour during two 8 h dose intervals. The results showed a significant correlation between the mean values of the AUC and the Cmin. First order elimination kinetics appeared to be followed by BCT, at least for the plasma concentrations commonly found. Considerable inter-individual variation was demonstrated both for the dose/plasma concentration ratio and for calculated plasma clearances. No serious side-effects were observed during the investigation.

    ABSTRACT: Administration of a single high dose of bromocriptine decreased synthesis and release of dopamine and serotonin in several brain regions, most notably in the striatum. Bromocriptine modified the kinetics of [3H]spiroperidol binding to striatal membranes, but these changes were not prominent 2 h after injection when modifications of monoamine metabolism were evaluated. After injection of the same dose of bromocriptine daily for 10 days, the decrease in dopamine synthesis persisted, while other aspects of monoamine metabolism, presumably controlled by dopamine autoreceptors, returned to normal values. This adaptation was not caused by decreased blood levels of bromocriptine, since bromocriptine accumulated in plasma after repeated drug administration. This study provides evidence that different aspects of dopamine cell function, presumably controlled by autoreceptors, show different patterns of adaptation after chronic administration of dopamine agonists.

    ABSTRACT: A simple and rapid RP-HPLC-DAD method was developed and validated for simultaneous determination of the dopamine antagonists haloperidol, its diazepane analog, and the dopamine agonist bromocriptine in rat plasma, to perform pharmacokinetic drug-interaction studies. Samples were prepared for analysis by acetonitrile (22.0 microg/mL) plasma protein precipitation with droperidol as an internal standard, followed by a double-step liquid-liquid extraction with hexane : chloroform (70:30) prior to C-18 separation. Isocratic elution was achieved using a 0.1% (v/v) trifluoroacetic acid in deionized water, methanol and acetonitrile (45/27.5/27.5, v/v/v). Triple-wavelength diode-array detection at the lambda(max) of 245 nm for haloperidol, 254 nm for the diazepane analog and droperidol, and 240 nm for bromocriptine was carried out. The LLOQ of DAL, HAL, and BCT were 45.0, 56.1, and 150 ng/mL, respectively. In rats, the estimated pharmacokinetic parameters (i.e., t(1/2), CL, and V(ss)) of HAL when administered with DAL and BCT were t(1/2) = 16.4 min, V(ss) = 0.541 L/kg for HAL, t(1/2) = 28.0 min, V(ss) = 2.00 L/kg for DAL, and t(1/2) = 24.0 min, V(ss) = 0.106 L/kg for BCT. The PK parameters for HAL differed significantly from those previously reported, which may be an indication of a drug-drug interaction.
