    Notes: Summary In 8 social drinkers, the effect of a single dose of Liv.52 or placebo on ethanol absorption has been studied after ingestion of 30 ml whisky in 5 min. The t1/2 absorption with Liv.52 was 3.62 min, significantly less than after placebo, 6.29 min. The peak concentration after Liv.52 (49.9 mg · 100 ml−1) was significantly higher than with placebo (40.5 mg · 100 ml−1). Whisky 120 ml consumed by regular alcohol users in 1 h, before and following 15 days of Liv.52 treatment produced significantly higher ethanol levels at 2, 3 and 4 h and significantly lower acetaldehyde levels at 3 and 4 h after Liv.52 treatment. Liv.52 enhanced the rate of absorption of ethanol and rapidly reduced acetaldehyde levels, which may explain its hepatoprotective effect on ethanol-induced liver damage.

    Notes: Summary Two, separate 6×6 Latin square cross-over bioequivalence studies were performed in adult male volunteers using 10 different indomethacin capsule preparations marketed in India together with the pure drug powder as the standard. The products were evaluated with respect to plasma level at various times up to 8 h following administration of a 50 mg (2 × 25 mg) dose. Plasma samples were analysed by a fluorimetric method. Various pharmacokinetic parameters were calculated according to a two compartment model. Statistical evaluation of the data employed analysis of variance for a cross-over design (ANOVA) and Duncan's multiple range test to ascertain the significance of differences between the products. Of the 10 products studied, two were found to be bioinequivalent.

    Notes: Summary Ethanol and acetaldehyde levels in blood and urine have been evaluated in 9 volunteers following administration of Liv.52 and placebo on the evening of the study and on the following morning. On the following morning the volunteers scored their symptoms and completed visual analogue scales. Single dose and multiple dose studies were done. Liv.52 produced a considerable reduction in blood and urine levels of ethanol and acetaldehyde after 12 h. It is possible that Liv.52 prevents the binding of acetaldehyde, bringing about higher initial blood levels followed by rapid elimination. It reduced the hangover symptoms.

    Description / Table of Contents: Resumé Objectif Le lévonorgestrel (LNG), à faible dose de progestine, n'a pas d'effet sur la lactation mais, comme tous les médicaments que prennent les femmes qui allètent, il peut être transmis au nourrisson dans le lait de la mère. Savoir comment les enfants de différents âges assimilent ce produit indésirable qu'ils ingèrent par le lait maternel permettrait de décider à quel moment on peut recommander cette méthode de contraception aux femmes durant la lactation. Méthode Cette étude a porté sur 30 femmes qui nourrissaient exclusivement au lait maternel leurs enfants de 4, 12 et 24 semaines. On a administré aux mères, pendant 5 semaines, des doses journalières de 30 μg de LNG, exposant ainsi l'enfant au médicament durant cette période. Résultats Les enfants de 4 semaines ne pouvaient ni absorber ni métaboliser efficacement le LNG. Ceux de 12 semaines pouvaient le métaboliser plus efficacement que l'absorber. Ceux de 24 semaines pouvaient et le métaboliser et l'absorber efficacement. Conclusion Le LNG peut être recommandé sans risque, 12 semaines après l'accouchement, aux mères qui allaitent leurs nourrissons.
    Abstract: Resumen Objetivo El levonorgestrel (LNG), progestina de dosis baja, no afecta la lactación pero, como todas las drogas administradas a madres lactantes, puede ser transferida al bebé a través de la leche materna. El modo en que los bebés de diversas edades manejan esta droga materna no deseada ayudaría a decidir cuándo recomendar este método anticonceptivo a madres lactantes. Métodos Este estudio se realizó con 30 madres exclusivamente lactantes y sus bebés de 4, 12 y 24 semanas de vida. Las madres recibieron diariamente 30 μg de LNG durante un período de cinco semanas, exponiendo así a sus hijos a LNG materno durante dicho período. Resultados Los bebés de 4 semanas no podían absorber ni metabolizar el LNG eficientemente. Los bebés de 12 semanas podían metabolizar el LNG más eficientemente que absorberlo. Los bebés de 24 semanas podían metabolizarlo y absorberlo eficientemente. Conclusión La administración de LNG a madres lactantes a las 12 semanas del posparto no representa problemas.
    Notes: Abstract Objective Levonorgestrel (LNG), a low-dose progestin, does not affect lactation but like all drugs taken by breastfeeding mothers, it can be transferred to the infant via breast milk. How infants of various ages cope with this unwanted maternal drug would help in deciding when to recommend this method of contraception to breastfeeding mothers. Methods The study was conducted in 30 exclusively breastfeeding mothers and their 4-, 12- and 24-week-old infants. The mothers daily received 30 μg LNG over a five-week period, thus exposing their infants to maternal LNG for that period. Results Four-week-old infants could neither absorb nor metabolize LNG efficiently. Twelve-week-old infants could metabolize LNG more efficiently than absorb. Twenty-four-week-old infants could do both efficiently. Conclusion It is safe to introduce LNG to breastfeeding mothers at 12 weeks postpartum.
