Purpose: To assess the physico-chemical stability of Voriconazole Eye-Drops (VED), when stored frozen and refrigerated once thawed, in 3 containers: Amber glass with a Low-Density PolyEthylene (LDPE) eyedropper, and two types of LDPE bottles: one classical and one with an innovative insert that maintains sterility after opening (Novelia® from Nemera).
Methods: Three batches of 1% VED (10 mL) were aseptically compounded from marketed injectable voriconazole (Vfend®) diluted in sterile water for injection. VEDs were stored for three months at -20 °C in amber glass (n = 32), classical LDPE (n = 32) or innovative LDPE (n = 31) bottles.
Background: Transforming a drug from its commercial form into a ready-to-use drug is common practice, especially in pediatrics. However, the risk of compounding error is real and data on drug stability in practice are not always available.
Aims: The aim of this study was to assess, in real conditions, both the error rate and stability of three drugs: ketamine, remifentanil, and sufentanil.
Background/aims: The in vivo metabolic profile of a benzopyridooxathiazepine (BPT) derivative, a potent tubulin polymerization inhibitor with a promising in vitro activity, was investigated.
Methods: The quantification of the BPT derivative and the identification of metabolites in the plasma of Wistar rats after i.p.
A micellar electrokinetic chromatography (MEKC) method was developed for the determination of three anti-vomiting drugs (aprepitant, dexamethasone and ondansetron) in pharmaceutical formulations. The method was optimized using a central composite design (CCD). Four main factors (borate buffer concentration, pH, methanol content and sodium dodecyl sulfate concentration) were optimized in order to obtain best resolutions and peak efficiencies in a minimum runtime.

First, simple and fast LC-UV methods have been optimized and validated to evaluate the pharmacokinetic profile of BZN using rat liver microsomes or hepatocytes primary cultures suspensions. Whatever the medium investigated, baseline resolution between the internal standard and BZN was achieved in a run time less than 15min using a Symmetry ODS column (150mm×4.
