Pharmaceutical Engineering: Optimization of a Pharmaceutical Formulation
The effects of magnesium stearate (MgSt) and shear stress on flow properties and hydrophobicity are not well known. Blends with different concentrations of magnesium stearate and varying amounts of shear were tested using three different procedures: the FT4 Rheometer test, a tap density analyzer, and the Washburn method, to better understand the relation of lubricant concentration, amount of sh...
متن کاملPharmaceutical formulation affects titanocene transferrin interactions.
Since the discovery of the anticancer activity of titanocene dichloride (TDC), many derivatives have been developed and evaluated. MKT4, a soluble, water-stable formulation of TDC, was used for both Phase I and Phase II human clinical trials. This formulation is investigated here by using (1)H and (13)C NMR, FT-ICR mass spectrometry, and UV/vis-detected pH-dependent speciation. DFT calculations...
متن کاملApplying Extrusion to Pharmaceutical Formulation Design
The drivers to produce solid solution formulations are reviewed together with specific challenges of implementing extrusion in a pharmaceutical setting. A solvent-based approach to screen formulations with less than 10 mg drug/screen is introduced and validated with experimental data. Process development challenges associated with the use of hygroscopic fine polymer powders are addressed throug...
متن کاملSpectrophotometric Determination of Corticosteroids and Its Application in Pharmaceutical Formulation
A simple, sensitive and economically viable spectrophotometric method for the determination of corticosteroids (predinsolone {PSL}, dexamethasone {DEX}, prednisone {PS}, betamethasone sodium phosphate {BEP} and hydrocortisone {HYD} has been developed. The method involves the oxidation of corticosteroids by iron (III) and subsequent complexation of iron (II) with potassium hexacynoferrate (III),...
متن کاملVoltammetric determination of vitamins in a pharmaceutical formulation.
Direct current polarography and differential pulse polarographic methods have been developed for the qualitative as well as quantitative analysis of vitamin B1, B2 and B6. Thiamin (vitamin B1) produced a well-defined wave in 0.1 M KCl at pH 5.2 with E(1/2)=-1.2 V and E(p)=-1.22 V versus saturated calomal electrode (SCE). Riboflavin (vitamin B2) gave two distinct waves in Britton Robinson buffer...
