Comparative, Single-Dose, 2-Way Cross-Over Bioavailability Study of Two Olanzapine 10 Mg Tablet Formulations in Healthy Volunteers Under Fasting Conditions.

: Olanzapine is an atypical antipsychotic that is approved across Europe, the USA, and in many other countries for oral treatment of schizophrenia and acute manic episodes in patients with bipolar disorder as well as for maintenance therapy to prevent recurrence in responders. The objective of the present study was to compare the pharmacokinetics of two 10 mg tablet formulations of Olanzapine following a single oral dose in healthy volunteers under fasting conditions, as per the European Medicine Agency (EMA) guidelines to grant marketing authorization. : This study was a randomized, open-label, two-treatment, two-period, two-sequences, single-dose, cross-over design with a washout period of 14 days.

Vitamin D levels and oxidative stress markers in patients hospitalized with COVID-19.

Background: COVID-19 is characterized by the presence of oxidative stress. Vitamin D status has been reviewed as one of the factors that may affect disease severity. The aim of this study was to assess the relationship between serum vitamin D levels, oxidative stress markers and disease severity in hospitalized COVID-19 patients.

Evaluation of oxidative stress markers in hospitalized patients with moderate and severe COVID-19.

Clinical evidence suggests increased oxidative stress in COVID-19 patients and this worsened redox status could potentially contribute to the progression of the disease. To investigate the oxidative stress we have measured oxidative stress parameters, namely, PAT (total antioxidant power, iron reducing) and d-ROMs (plasma peroxides). Additionally we have investigated their correlation with the most frequently used clinical parameters CRP, LDH, and NLR in serum from moderate and severe COVID-19 patients hospitalized in a tertiary hospital.

Frequencies of single-nucleotide polymorphisms and haplotypes of the SLCO1B1 gene in selected populations of the western balkans.

As a membrane influx transporter, organic anion-transporting polypeptide 1B1 (OATP1B1) regulates the cellular uptake of a number of endogenous compounds and drugs. The aim of this study was to characterize the diversity of the solute carrier organic anion transporter family member 1B1 (SLCO1B1) gene encoding this transporter in two ethnic groups populating the Western Balkans. The distribution of SCLO1B1 alleles was determined at seven variant sites (c.

Effects of single nucleotide polymorphisms and haplotypes of the SLCO1B1 gene on the pharmacokinetic profile of atorvastatin in healthy Macedonian volunteers.

OATP1B1 is an influx transporter known to mediate the uptake of various endogenous compounds and xenobiotics. Several sequence variations have been discovered in the SLCO1B1 gene encoding OATP1B1. The aim of this study was to investigate the effects of SLCO1B1 polymorphisms on the pharmacokinetics of atorvastatin in healthy volunteers of Macedonian origin.

Determination of Acyclovir in Human Plasma Samples by HPLC Method with UV Detection: Application to Single-Dose Pharmacokinetic Study.

Background: The aim of this study is estimation of pharmacokinetic parameters: Cmax, tmax, t1/2, AUC0-t and AUC0-∞ with the two-way analysis of variance, single observation (ANOVA) for two preparations containing acyclovir.

Objective: In order to evaluate pharmacokinetic study of acyclovir, method for quantitative determination of acyclovir in human plasma should be simple, rapid and reproducible. Therefore, the method is developed, validated and applied for analysis of acyclovir in plasma samples obtained from healthy volunteers.
