NEW InhaLac® 160: MEGGLE extends inhalative lactose grade portfolio

products-servicesMEGGLE Excipients & Technology
November 13th 2018



MEGGLE’s newest sieved grade of lactose monohydrate, InhaLac® 160, is ideal for pulmonary and nasal dry powder inhalation applications.

Characterized by a median particle size of approximately 110 μm, the new InhaLac® 160 fills a gap in the InhaLac® range of coarse sieved lactose grades for dry powder inhalation, sitting between the coarser lactose InhaLac® 120 and the finer lactose InhaLac® 230.

This GMP/GDP certified sieved lactose is therefore suitable for pulmonary and nasal drug delivery and offers a range of benefits that include a dedicated production process, highly controlled powder characteristics, highest microbial quality including low endotoxins and retesting after 24 months.

Design & Features

Developed at MEGGLE’s Wasserburg laboratories in Germany, this inhalation grade lactose exhibits a narrowly distributed particle size with a fines content (particles below 15 μm) of 3%. Combined with high quality and safety, this material will meet individual requirements for dry powder inhalation formulations.

InhaLac® 160 features a particle size distribution between the coarser lactose InhaLac® 120 and the finer lactose InhaLac® 230 of:

  • x10: 55-85 µm
  • x50: 90-120 µm
  • x90: 125-165 µm

User benefits:

InhaLac® 160 is a sieved lactose monohydrate for inhalation with distinct particle size distribution that extends MEGGLE`s product portfolio of inhalative lactose grades, closing the gap of coarse sieved lactose grades for dry powder inhalation. In summary, InhaLac® 160 offers a potent range of overall benefits:

  • Highly controlled powder characteristics
  • Highest microbial quality including low endotoxins
  • High stability means retest is only required biennially

Quality & Certification

MEGGLE’s InhaLac® alpha-lactose monohydrate grades comply with the current harmonized USP-NF, Ph.Eur., and JP monographs. The strict microbial limits of MEGGLE`s InhaLac® formulations characterizes them as inhaler grades to meet the special requirements for dry powder inhalation. All InhaLac® products are manufactured on product lines that are exclusively dedicated to inhalative lactose.

The pharma-dedicated MEGGLE production facility in Wasserburg, Germany holds an EXCiPACTTM Certificate and has implemented GMP according to the Joint IPEC-PQG Good Manufacturing Practices Guide.
