DescriptionLactose (Henrifarma)
SynonymsAnhydrous 60M; Anhydrous Direct Tableting (DT); Anhydrous DT High Velocity; Anhydrous Impalpable; Lactopress Anhydrous; Lactopress Anhydrous 250; lactosum anhydricum; lattosio; milk sugar; SuperTab 21AN; SuperTab 22AN; saccharum lactis
Related sunstancesLactose, inhalation; lactose, monohydrate; lactose, spray-dried
Functional categoryDirectly compressible tablet excipient; dry powder inhaler carrier; lyophilization aid; tablet and capsule diluent; tablet and capsule filler
ConditionsMold growth may occur under humid conditions (80% RH and above). Lactose may develop a brown coloration on storage, the reaction being accelerated by warm, damp conditions. At 80℃ and 80% RH, tablets containing anhydrous lactose have been shown to expand 1.2 times after one day. Lactose anhydrous should be stored in a well-closed container in a cool, dry place.

Glimepiride-Lactose incompatibilities


Reation typePhysical interaction
Mechanism
Mechanism descriptionThe thermal decomposition of glimepiride (sulfonylurea hypoglycemic agent) was studied using differential scanning calorimetry (DSC) and thermogravimetry/derivative thermogravimetry (TG/DTG). The 1:1 physical mixtures of these excipients with glimepiride showed physical interaction of the drug with Mg stearate, lactose and Plasdone®. On the other hand, IR results did not evidence any chemical modifications.
