Iron Pharmacokinetics in Women with Iron Deficiency Anaemia Following A Single Oral Dose of a Novel Formulation of Tardyferon (Prolonged Release Ferrous Sulphate).

Numerous iron-containing preparations are available on the market; these vary in dosage, salt, chemical state of iron (ferric or ferrous) and in the iron delivery process (immediate or prolonged-release). Tardyferon® is a prolonged-release tablet containing 80 mg ferrous sulphate. The formulation has recently been modified; changes to the excipients which constitute the inert formulation matrix have allowed a decrease in tablet size for easier swallowing.

Pharmacokinetics of Ferrous Sulphate (Tardyferon®) after Single Oral Dose Administration in Women with Iron Deficiency Anaemia.

Iron-containing preparations available on the market vary in dosage, salt, and chemical state of iron contained in the preparation, as well as in the iron delivery process (immediate or prolonged-release). The present study aimed at characterizing the serum pharmacokinetics of iron in non pregnant women with iron deficiency anaemia (IDA) following a single oral administration of a prolonged-release ferrous sulphate tablet. This multicenter, single dose, open-label study was conducted in 30 women aged between 18 and 45 years with IDA.

Extruder scale-up assessment in the process of extrusion-spheronization: comparison of radial and axial systems by a design of experiments approach.

Scaling-up the extrusion-spheronization process involves the separate scale-up of each of the five process steps: dry mixing, granulation, extrusion, spheronization, and drying. The aim of the study was to compare two screw extrusion systems regarding their suitability for scaling-up. Two drug substances of high- and low-solubility in water were retained at different concentrations as formulation variables.

Improved training of neural networks for the nonlinear active control of sound and vibration.

Active control of sound and vibration has been the subject of a lot of research in recent years, and examples of applications are now numerous. However, few practical implementations of nonlinear active controllers have been realized. Nonlinear active controllers may be required in cases where the actuators used in active control systems exhibit nonlinear characteristics, or in cases when the structure to be controlled exhibits a nonlinear behavior.
