Coagulation in familial hypercholesterolemic patients: effect of current hypolipidemic treatment and anticoagulants.

Familial hypercholesterolemia (FH) is a relatively rare genetic disease associated with high serum cholesterol levels but also with abnormalities in blood coagulation. Novel pharmacotherapeutic approaches in FH including proprotein convertase subtilisin/kexin type 9 antibodies (PCSK9Ab) are very efficient in decreasing cholesterol levels but their impact on coagulation in FH is not yet established. Therefore, we hypothesized that these novel antidyslipidemic drugs can positively impact blood coagulation due to their more potent effect on cholesterol.

Comparison of the liquisolid technique and co-milling for loading of a poorly soluble drug in inorganic porous excipients.

Drug loading into mesoporous carriers may help to improve the dissolution of poorly aqueous-soluble drugs. However, both preparation method and carrier properties influence loading efficiency and drug release. Accordingly, this study aimed to compare two preparation methods: formulation into liquisolid systems (LSS) and co-milling for their efficiency in loading the poorly soluble model drug cyclosporine A (CyA) into mesoporous magnesium aluminometasilicate Neusilin® US2 (NEU) or functionalized calcium carbonate (FCC).

Analysis of terbinafine in PLGA-based drug delivery systems by a fast and sensitive UHPLC-DAD method.

A novel ultra-high performance chromatography method with multichannel detection that allows fast, sensitive, and robust analysis of an antifungal drug terbinafine and its three main impurities β-terbinafine, ()-terbinafine, and 4-methylterbinafine in just 5.0 min has been developed. Analysis of terbinafine is important in pharmaceutical analysis since it enables the detection of its impurities at very low concentrations.

Vitamin K - sources, physiological role, kinetics, deficiency, detection, therapeutic use, and toxicity.

Vitamin K is traditionally connected with blood coagulation, since it is needed for the posttranslational modification of 7 proteins involved in this cascade. However, it is also involved in the maturation of another 11 or 12 proteins that play different roles, encompassing in particular the modulation of the calcification of connective tissues. Since this process is physiologically needed in bones, but is pathological in arteries, a great deal of research has been devoted to finding a possible link between vitamin K and the prevention of osteoporosis and cardiovascular diseases.
