Lactose is a sugar naturally present in mammal’s milk. It has been used in the pharmaceutical industry for several decades as an excipient. It is either used as a Diluent in oral solid dosage forms (OSDF) such as tablets, capsules, sachets or as a Carrier for dry powder inhalers (DPI) because pure active substances need excipients to produce a final dosage form.
Pharma grades meet all the pharmacopoeia requirements of Ph. Eur., USP-NF and JP monographs.
Several properties such as cost effectiveness, a bland taste, its availability and the compatibility with active ingredients and other excipients contribute to the popularity of lactose . Further advantages of lactose are its water solubility, its low hygroscopicity, as well as the excellent physical and chemical stability.
Mostly used for tablet manufacturing using wet and dry granulation, but also for blends or premixes.
