Abstract The objective of this work was to assess the effect of process parameters of a dosator nozzle machine on the powder bed uniformity of inhalation powders with various characteristics during a low-dose dosator capsule filling process. Three grades of lactose excipients were extensively characterized and filled into size 3 capsules using different dosing chamber lengths (2.5, 5mm), nozzle diameters (1.9, 3.4mm), powder bed heights (5, 10mm) and filling speeds (500, 3000capsules/h).The...

Abstract The purpose of the present study was to develop a near-infrared spectroscopy (NIRS) method to quickly, accurately, and precisely evaluate and control the coating process of the low dose drug, glimepiride on tablet. For this purpose, a calibration set for the drug was quantified using a partial least-squares regression method with a high-performance liquid chromatography (HPLC) as the reference method. The correlation coefficient (R2) between the NIRS method and the HPLC method in the...
