• Spray-Congealing and Wet-Sieving as Alternative Processes for Engineering of Inhalation Carrier Particles: Comparison of Surface Properties, Blending and In Vitro Performance.: The study provides a comparative analysis of spray-congealing and wet-sieving processes in engineering carrier particles for inhalation, utilizing a-Lactose monohydrate (Pinto et al., 2021).


• Conversion of a-lactose monohydrate to anhydrous form with superior tabletability by twin-screw extrusion at elevated temperature.: Discusses a method for converting a-Lactose monohydrate to a more compressible anhydrous form, enhancing its application in tablet manufacturing (Batra et al., 2020).

Biochem/physiol Actions

alpha-Lactose is the primary sugar present in milk and the main energy source to a newborn mammalian through its mother′s milk. It is digested by the intestinal lactase (EC 3.2.1.108), an enzyme expressed in newborns. The enzyme′s activity declines following weaning which can lead to lactose intolerance in adult mammals.
