In vitro/in vivo correlation of prolonged release dosage forms containing diltiazem HCl

Six preparations were considered: three multiple unit dosage forms (micropellets in capsules) (D, E and G) and one matrix tablet (B) were experimental prolonged release formulations, two non-disintegrating tablets (A and C) were commercial products. The in vitro dissolution behaviour of the differing formulations was investigated using the USP XXII paddle apparatus. The in vivo study was effected on a panel of 12 healthy volunteers. The two commercial tablets (A and C) showed mean dissolution time (MDT) of 1.34 and 1.44 h and t_d of 91 and 92 min, respectively; for prolonged release formulations (B, E, D, and G) MDT ranged between 2.28 and 4.23 h and t_d between 149 and 291 min. The mean residence time (MRT) was 8.68 and 6.47 h for tablets A and C, respectively; it ranged between 9.62 and 10.24 h for the multiple unit formulations E, D, and G and was 11.27 h for matrix B. Formulation B also showed the higher apparent elimination half-life t_1/2 (7.12 h), while apparent t_1/2 for all the other formulations were very similar, ranging between 5.04 and 5.28 h. High variability between the various formulations was found for C_max and AUC values, and no relationships could be established with the type of formulation. An in vitro/in vivo correlation was found for all the formulations examined on the basis of analogous parameters (MDT and MRT); (r = 0.83, p <0.05). In a few cases the Wagner-Nelson deconvolution method was applied to individual plasma level versus time curves and the corresponding absorption curves were obtained. In these cases the in vitro/in vivo correlation was tested on the basis of the comparison of the in vivo absorption curves with the in vitro dissolution profiles. This was accomplished using the ‘Levy's plot’ (per cent released versus per cent absorbed) approach and provided further support for the correlation found.

Effect of buffering on pharmacokinetics of ketoprofen enantiomers in man

Aims Concomitant administration of magnesium hydroxide may affect the rate or extent of absorption of non-steroidal anti-inflammatory drugs. In order to find out whether or not buffering modifies the pharmacokinetics of ketoprofen, plasma concentration-time courses resulting from oral administration of unbuffered formulations were compared with those of buffered formulations.
Methods Two groups of 12 healthy and young male subjects were included in two randomized cross-over studies and received single oral doses of ketoprofen 12.5 or 25  mg, respectively, given as tablets which were either unbuffered or buffered with magnesium hydroxide/citrate. Ketoprofen enantiomers in plasma were determined by h.p.l.c. up to 24  h post-dose.
Results Maximum plasma concentrations ( C _max ) of both the (R)- and (S)-enantiomer, observed after administration of the buffered formulations (12.5 and 25  mg), were higher compared with the unbuffered tablets by about 50–80%. The area under concentration-time data (AUC) was unaffected, and, hence, C _max/AUC was increased by buffering. Time to C _max ( t _max ) and mean residence time (MRT) tended to be or was shortened by buffering.
Conclusions It is concluded that buffering of two ketoprofen formulations with magnesium hydroxide/citrate enhanced the concentration maximum by increasing the rate of absorption and leaving AUC unaffected.     

Marital Functioning in Early Versus Late-Onset Alcoholic Couples

Current knowledge about alcohol and marital functioning is limited by restrictive sample selection, inattention to the literature on individual-based alcoholic subtypes, and lack of research linking individual differences among alcoholics to marital functioning. The present study was designed to study marital functioning of alcoholics in light of current alcohol typologies. Subjects were part of a larger study on conjoint treatment of alcoholic males and their female partners. Four typologies—including Type 1/2, In-Home/Out-of-home, SteadyIEpisodic, and EarlyILate Onset—were tested for replicability and discriminant validity before linking them to marital functioning. Discriminant validity was found only for the Early (59%)-versus Late (41 %)-Onset typology; thus, further analyses linked only this typology with marital functioning. At baseline, Early-Onset couples reported more marital instability, and the females in these couples were more distressed. During treatment, Early-Onset couples reported higher daily marital satisfaction than Late-Onset couples. Regardless of age of onset, males reported higher marital satisfaction than their spouses during treatment, but their satisfaction did not increase during treatment. Female partners' marital satisfaction increased during treatment. Female partners of Late-Onset males reported particularly low marital satisfaction during treatment. Parsing the sample according to the early-/late-onset typology yielded different predictors of marital satisfaction for males and females within each subtype. For female partners of Early-Onset alcoholics, psychological distress unrelated to her pattner's drinking severity was most associated with her own marital satisfaction, whereas marital adjustment of female partners of Late-Onset alcoholics was most associated with the male's level of perceptual accuracy regarding her needs. This pattern was reversed for the males; marital adjustment of Early-Onset alcoholics was most associated with his partner's perceptual accuracy of his needs, whereas marital functioning of Late-Onset alcoholics was best accounted for by his own psychological distress.     

Erinnerungen an traumatische Erlebnisse in der Zeit des Nationalsozialismus bei (ehemaligen) jüdischen Emigranten und Lagerhäftlingen

Zusammenfassung Halbstrukturierte Inteviews mit 248 (ehemaligen) jüdischen Emigranten und Lagerh?ftlingen in Deutschland und drei Ziell?ndern der jüdischen Emigration zeigen, da? Erinnerungen an traumatische Erlebnisse im Nationalsozialismus in zahlreichen allt?glichen Kontexten auftreten und von zentraler Bedeutung für die Wahrnehmung der pers?nlichen Lebenssituation im Alter sind. Auf der Grundlage der Ergebnisse einer Pilotstudie zur Frage nach der subjektiven Gliederung des Lebenslaufs bei (ehemaligen) jüdischen Emigranten und Lagerh?ftlingen werden unterschiedliche Abschnitte der pers?nlichen Entwicklung nach dem Holocaust unterschieden. Selbsteinsch?tzungen der Untersuchungsteilnehmer zur Intensit?t von Erinnerungen an traumatische Erlebnisse in diesen Entwicklungsabschnitten unterstützen die Annahme, da? belastende Erinnerungen im Alter deutlich zugenommen haben. Die Untersuchungsteilnehmer unterscheiden sich erheblich in den Formen der Auseinandersetzung mit solchen Erinnerungen. Einige Untersuchungsteilnehmer reagierten mit Depressionen, Angstzust?nden, Gefühlen von überlebensschuld und Rückzug aus sozialen Beziehungen. Andere engagierten sich hingegen in hohem Ma?e in sozialen Beziehungen, vor allem zu Angeh?rigen der jüngeren Generation, um dadurch zur Vermeidung von Diskriminierung, Rassismus und Fremdenfeindlichkeit beizutragen.

Micro- and macro-consequences of ooplasmic injections of early haploid male gametes

This review refers to the evolution of ooplasmic injectionsof round spermatid nuclei ROSNI) or intact round spermatidsROSI). Conclusions from their preliminary application in thehamster, rabbit, mouse and human are discussed. Criteria foridentification of round spermatids and guidelines/quality controlfor application of ROSNI/ROSI techniques are emphasized. Althoughall the animal offspring and the human newborns delivered afterROSNI/ROSI are healthy additional research efforts are necessaryto confirm the safety of these procedures and improve theiroutcome
