Potential factors of resistance to clarithromycin.

Objectives: A comparative dissolution kinetics test (CDKT) and bioequivalence studies of generic proton pump inhibitors (PPIs) do not model pharmacological acid suppression (PAS) and pathological duodenogastric reflux (PDGR). This study aimed to model them in CDKT to assess drugs stability and potential pantoprazole-clarithromycin interactions.

Methods: In CDKT, PDGR (dissolution medium pH 7.

[Pharmacotherapy of allergic rhinitis: position of a clinical pharmacologist].

Pharmacotherapy for allergic rhinitis is based on different categories of drugs used either in monotherapy or in combination regimens. The current clinical guidelines suggest a stepwise approach to pharmacotherapy for allergic rhinitis. The use of intranasal corticosteroids is considered as the preferred second-stage pharmacotherapy.

Comparative study of the bioavailability of magnesium salts.

Background High values of endogenous levels of magnesium (Mg) in the body and mechanisms of homeostasis regulation make it difficult to assess the bioavailability of these drugs. The aim of this study was to assess the Mg concentration in blood in volunteers and in erythrocytes in patients with hypomagnesemia. Methods The study included 20 healthy volunteers and 62 patients with chronic heart failure (CHF) I-III functional class (FC) NYHA classification.

[Dynamics of changes of blood inflammatory-oxidative biomarkers in acute coronary syndrome].

Some inflammatory cytokines and parameters of low density lipoproteins (LDL) oxidative modification were studied in blood of 250 acute coronary syndrome (ACS) patients--Siberian inhabitants, men and women with myocardial infarction (MI) or unstable angina on first, tenth and thirtieth days of disease. The inflammatory biomarkers in men and women with MI are: increased concentrations of interleukin (IL)-6, IL-8 and C-reactive protein (CRP), especially on the first day of disease. The most significant inflammatory biomarker of ACS is increased CRP level, especially in women.
