The pharmacokinetics of miconazole were studied after intravenous administration to six sheep (4 mg/kg) of three aqueous solutions: a marketed micellar solution containing polyoxyl-35 castor oil (Daktarin IV(R)) was compared with two solutions both containing 50 mM lactic acid and a cyclodextrin derivative (100 mM HP-betaCD or 50 mM SBE7-betaCD). The aim of this work was to demonstrate that these cyclodextrin derivatives (CDs) have no effect on the pharmacokinetics of miconazole by comparison with the micellar solution. The plasma concentration time curves have shown that there is no significant difference between the three solutions. [less ▲]

The antimycotic activity of a new parenteral solution containing miconazole was compared to that of a marketed solution (Daktarin IV solution). This solution has been withdrawn from the belgian market probably because of the toxic effects related to the presence of polyoxyl 35 castor oil. We propose a new formulation containing 10 mg of miconazole per ml (as the marketed solution), in combination with HP-beta cyclodextrin and lactic acid. The MIC of these two solutions were determined by broth microdilution method (following the NCCLS guidelines) against 15 yeasts and 16 filamentous fungi isolates. This study showed that MIC obtained with these two solutions are not significantly different. In vitro, the cyclodextrin solution has the same antimycotic activity as the Daktarin IV solution and can be proposed as a safe and effective parenteral solution to replace the previous surfactant solution.

L'albendazole est une dérivé benzimidazole à large spectre d'activité contre les parasites helminthiques de l'homme et de l'animal. L'albendazole est très faiblement soluble dans l'eau. Il a été démontré que les cyclodextrines sont capables de former des complexes d'inclusion avec l'albendazole et d'en augmenter la solubilité. La solubilité aqueuse de l'albendazole est dépendante du pH. Le but de ce travail est d'étudier l'influence combinée des cyclodextrines et de différents acides sur la solubilité de l'albendazole. Il a été démontré qu'il existe un véritable effet synergique entre les cyclodextrines et les différents acides. L'utilisation combinée d'hydroxypropyl-b-cyclodextrine (200 mM) et d'acide lactique ou acide citrique (50 mM) permet de dissoudre plus de 1 mg/ml d'albendazole. Des études RMN ont démontré l'inclusion de l'albendazole dans la b-cyclodextrine en milieu acide. Ces résultats montrent qu'il est possible de réaliser une solution injectable et une solution orale d'albendazole grâce aux cyclodextrines. [less ▲]

Simultaneous reactivation of distinct Herpesviridae with development of clinical manifestations is exceptional. We report a 48-year-old woman suffering from idiopathic thrombocytopenic purpura. As the disease remained refractory to corticosteroids, immunoglobulins and splenectomy, a cure of vinblastine was administered. An atypical stomatitis developed few days later. Immunohistochemistry on a Tzanck smear and a biopsy evidenced a Herpes simplex virus type 1 (HSV-1) infection. The patient presented simultaneously a single necrotic lesion on the abdomen. Immunohistochemistry on a skin biopsy revealed the presence of the varicella-zoster virus (VZV) gE, gB and IE63 proteins. Intravenous aciclovir was initiated. The present case of simultaneous clinical infections by HSV-I and VZV underlines the importance of complementary viral identification testing in the event of unusual clinical presentations. [less ▲]

Miconazole is an antimycotic drug exhibiting a very poor water solubility (B1.03 mg:ml). It has been shown that cyclodextrins (CDs) are able to form inclusion complexes with miconazole and that they are able to increase its aqueous solubility. Miconazole is a weak base whose solubility depends of the pH. The purpose of this study was to investigate the influence of both CDs and different acids on the solubility of miconazole. It was found that a synergistic effect existed between CDs and different acids. The combination of hydroxypropyl-bCD (HP-bCD) (100 mM) or sulfobutylether 7-bCD (SBE7-bCD) (50 mM) and lactic acid (50 mM) allowed to dissolve more than 10 mg of miconazole per ml. NMR studies confirmed the formation of an inclusion complex miconazole–CD in an acidic medium. It was also shown by the NMR studies that the complex formed was a 1:1 complex. These results demonstrate that it is possible to develop a parenteral aqueous solution of miconazole without surfactant. [less ▲]
