Reta M®: MEGGLE´s first lactose-free co-processed excipient for modified release formulations
Co-processing specialist MEGGLE Excipients & Technology (MEGGLE) has developed Reta M®. The first hypromellose/mannitol-based, co-processed excipient specifically designed for direct compression (DC) and dry granulation of modified release formulations for the pharmaceutical and nutraceutical market.
MEGGLE has been known as one of the key lactose excipient manufactures and pioneer of co-processed excipients for decades. In 2009 MEGGLE introduced RetaLac® a combination of lactose monohydrate and hypromellose, tailored specifically to sustained drug release formulation, which can be easily produced by direct compression. Due to its ease of use and reliant performance, RetaLac® has been very well received by the pharmaceutical industry. On the other hand nutritional industry has been missing out on the benefits of RetaLac®, due to its reluctance to use lactose or lactose-based excipients. One can imagine, it was a tough decision for MEGGLE to embrace excipients, which do not contain lactose. But here we are, MEGGLE introduces its first lactose-free excipient, Reta M®, comprising 50 % Mannitol and 50 % hypromellose (K4M). Reta M® easily enables sustained drug formulation through direct compression.

Powder characterization
Reta M®’s PSD and bulk density are right in the range of providing free flow, good blending capabilities and compaction behavior. Its powder flow ranks as “Fair-aid not needed”. Co-processing two or more excipients generally improves the resulting excipient’s compactibiltiy over its physical ad-mixture. This effect can also be seen for Reta M®. It shows a quite linear increase of tablet hardness as function of employed compaction pressure, which allows for reliable and better-to-predict product performance.
In order to achieve drug release in a sustained manner, MEGGLE has selected hypromellose K4M. MEGGLE has seen, the use of hypromellose grades, which provide higher viscosity does not necessarily lead to improvements in slowing down the drug release. In addition, the use of high-viscosity hypromellose compromise important excipient’s functional related characteristics, which has led to the decision to stick with hypromellose’s K4M type.
Packaging, storage, shelf-life
Reta M® comes in a 15 kg carton box, while pharma-compliant polyethylene-inline is being used as primary packaging with a shelf life of 24 month.
