Product Overview and Decision Matrix

MEGGLE has it.The right spray-dried lactose product for direct compression

Spray-drying (SD) opened the door for lactose in Direct Compression (DC) and had a major impact on tableting technology. After initial quality problems, SD lactose has become a very frequently used, robust excipient grade in pharmaceutical formulation design.

Nowadays, pharma grade lactose is manufactured first, and then converted into SD lactose, avoiding former browning due to the use of a contaminated mother liquor. SD lactose is an excellent example demonstrating the versatility of this material: Besides thermodynamically most stable polymorph α-lactose monohydrate, a precisely defined percentage of amorphous lactose is created in a tailored particle design process using a lactose suspension.

Important: Amount of amorphous lactose

The amount of amorphous lactose can be determined by the lactose dissolved before the atomization step. Generally, SD lactose grades expose between 10 to 15% amorphous lactose, and an aqueous lactose solution contains a majority of ß-anomer, especially at elevated temperatures. This ratio is basically not changed after dispersion, when due to rapid dehydration no formation of a structured crystal lattice is possible. Lactose molecules arrange more the less randomly containing some traces of water. Lack of an ordered structure is seen the reason for its adhesive, more plastically deforming compaction behavior, while sphenoidal, structure-giving, α-lactose monohydrate crystals (also denoted as “tomahawk”-shaped) tend more to consolidate by fragmentation.

Spray-drying: Modulation of porous particles

A combination of these two compaction behaviors favors synergistically tableting and simultaneously loadability of a compact. In a typical SD process a liquid or slurry is rapidly dispersed into a controlled drop size, and its physical shape is preserved by a hot, counter-flowing gas, streaming against the dispersing atomizer.  In SD lactose manufacture only aqueous systems are used, drying agent is just hot air. The formation of spherical aggregates of narrow particle size distribution (PSD) impacts powder technological aspects dramatically: Flowability of product is greatly enhanced by spherical shape of agglomerates and smooth surface enabling excellent tablet mass and content uniformity values. Besides that, SD also allows to modulate porosity of particles, which may be applied increasing compaction performance, as well as reducing lubricant sensitivity.

MEGGLE’s spray-dried lactose grades for direct compression are available under the trade names

FlowLac ® 90 and FlowLac® 100

Cellactose® 80

Lactose and Cellulose are very well established excipients. Both are naturally derived and frequently used as diluent/binder in oral dosage formulations (ODT).

In an effort to obtain synergistic effects, such as improved tablet hardness and adherence capacity, by co-processing both excipients, spray-drying was used in order to bring lactose and cellulose together.

As a result Cellactose® 80, a co-processed excipient, was achieved that provides capability for direct compression, due to given flowability and compactability. Cellactose® 80 is made up of 75 % alpha-Lactose-monohydrate and 25 % powdered cellulose.

MEGGLE has it. The right co-processed excipients for direct compression

The use of co-processed excipients (CPE) are by far the easiest and fasted way to develop solid oral dosage forms.

The solution: Co-processed excipients

Traditional excipients struggle to cope with current challenges in drug development such as high speed tableting, developing direct compression formulation, low dose related content uniformity issues and insufficient tablet hardness due to high dose loading. Co-processed excipients are in essence the solution to each problem, provided that the right CPE is chosen.

At MEGGLE each CPE was developed having a specific problem in mind, which needs to be solved. Therefore MEGGLE provides a wide range of CPEs. The individual components are of pharmacopoeial quality and are brought together in a sophisticated, controlled manner, resulting in the highest degree of material robustness with regard to their functional related characteristics (FRCs). As quality by design (QbD) gains more and more importance, developers’ need for tightly controlled critical material attributes (CMA) are one of the key benefits of CPEs. The inherent variability of each excipient in a traditional powder blend, which adds up to inherent product variability, can be addressed easily by the use of CPEs, as their manufacturing can be fine-tuned, adding another layer of control, which is impossible to achieve by a simple operation such as blending.

Advantage: Stable ratio of components

Furthermore the ratio of the individual components within the CPE remains stable throughout the entire production process, as these components cannot be separated by physical means. It is important to note that co-processing must not lead to chemical alteration of the individual components.

Important: Full compliance with regularly bodies

Through MEGGLE’s expertise in co-processing, MEGGLE assures full compliance for its CPEs products with regularly bodies around the globe. CPEs are no exception when it comes to its GMP production according to the Joint IPEC-PQG Good Manufacturing Practices Guide for Pharmaceutical Excipients, and USP General Information Chapter 1078. In addition, MEGGLE provides drug master files for all of its CPE, which can be used in conjunction with drug approval by the FDA. It is MEGGLE’s understanding to support its customers from start, providing the first samples, throughout the whole drug development, registration process, and drug product’s life cycle, to finish.

MEGGLE´s co-processed excipients for direct compression are available under the trade names: MicroceLac® 100, Cellactose® 80, StarLac®, RetaLac®, Reta M® and CombiLac®

MEGGLE invented in the 70´s the well-known and popular product family Tablettose® – A robust agglomeration technique translates into a robust excipient, which is essential to robust drug manufacturing.

Tablettose® is produced in a continuous manufacturing, a concept which is still quite new for the pharmaceutical industry, but very well accepted and understood by the food industry.

Continuous manufacturing: Reduced production cost:

MEGGLE’s deeply rooted expertise in food production and willingness to conquer the pharmaceutical industry helped a lot to apply the concept of continuous manufacturing to the production of pharmaceutical grade excipients. Not only can MEGGLE take advantage of reduced production cost through continuous manufacturing, which allows for very competitive pricing, a consistent product quality and performance can be achieved through continuous manufacturing.

Agglomerated lactose: Excellent flowability and compactibility

The beauty of agglomerated lactose is its given functionality (excellent flowability and compactibility), while its regulatory status is “save”. Tablettose® complies with all compendial requirements worldwide, which are set for lactose monohydrate. This means, whenever lactose monohydrate is considered as part of a pharmaceutical drug formulation, the drug developer has a highly functional excipient on hand, which’s regulatory status is crystal clear and accepted by the authorities.

Tablettose®: For moisture-sensitive API formulations

Although MEGGLE uses a fair amount of water for lactose’s agglomeration, the final product provides a remarkable low amount of potentially active surface water (less than 0.5 %), which allows for the use of Tablettose® in formulations, which containing moisture-sensitive active pharmaceutical ingredients (API). As lactose monohydrate is non-hygroscopic by any means, stability issues, due to water uptake, should not be of any concern.

The Tablettose® family comprises 3 members to date, each one having its distinct advantages. Tablettose® 80 covers the broadest range of drug formulations and is therefore the first go-to choice when it comes to cost effect and reliable direct compression.

MEGGLE’s agglomerated lactose grades suitable for direct compression are available under the trade names

Tablettose® 70, Tablettose® 80 and Tablettose® 100

MEGGLE has it. The right milled lactose product for wet and dry granulation

In traditional, pharmaceutical dry and wet granulation operation finer particles have proven to be beneficial.

Milled α-lactose monohydrate is available in fine particle size (PS) with narrow particle size distribution (PSD), defined surface properties and density ranges. This allows to modulate in particular a solid formulation’s compactibility, compressibility, porosity, and segregation tendency. Brittle α-lactose monohydrate exhibits good binding properties, and consolidates mainly by fragmentation, but particle flow of milled lactose grades is moderate, depending on size and its corresponding specific surface

Milled lactose grades: A perfect product platform

However, for many important pharmaceutical agglomeration processes (e.g. in economical direct compression) both compactibility and flowability are primordial. Milled lactose grades represent a perfect product platform, for they can be modified greatly, fulfilling the needs of various applications. Impacting particle characteristics by agglomeration has been an early undertaking, where flowability was optimized by a simple and gentle particle size enlargement step, leading into the product family of agglomerated Tablettose®. Dispersion of a milled lactose suspension through a nozzle allows to optimize particle porosity, shape and surface in one step, resulting into the product group of spray-dried lactose (FlowLac® 90/100).

Variety of PSD: Flexibility in tableting

Milled lactose grades also have a long tradition in dry granulation procedures using roller compaction or slugging. These processes consist of a primary agglomeration and a final milling step. In roller compaction due to force feeding reduced powder flow is of minor importance, in some cases low segregation tendency of milled lactose grades may be even seen advantageous for content uniformity reasons. In well-established slugging processes flat compacts are manufactured preferentially avoiding die filling issues. MEGGLE offers a variety of PS/PSD of milled lactose grades offering flexibility in tableting during the second compaction step.

Extrusion/spheronization processes also make use of milled lactose as a filler. 

After all, disaccharide lactose may be metabolized by bacteria or fungi and is mainly used in its milled form as bulk substrate/medium for fermentation in bio-industries.

GranuLac® 70, GranuLac® 80,  GranuLac® 140, GranuLac® 200, GranuLac® 230 and SorboLac®400

MEGGLE has it. The right lactose product for dry powder inhalation

InhaLac® stands for a lactose, which is, in particular, suitable for use in pulmonary and nasal drug delivery.

Inhalation aerosols offer the potential for needle-free systemic delivery of small molecule drugs as well as therapeutic peptides and proteins. An industry standard in dry powder inhalation formulation development, lactose monohydrate is used safely in DPI formulations. Using lactose as an excipient not only improves performance efficiency of the inhaler, but also facilitates powder handling during production. Effective performance of a dry powder inhaler largely depends on the carrier material used for the drug formulation.

Lactose: Carrier of API

Customization has been seen for MEGGLE products, traditionally used for the oral route of administration but is especially important when it comes to the inhalation route of administration, in particular dry powder inhaler (DPI), where lactose plays a predominant role as carrier for the active pharmaceutical ingredient (API) facilitating its delivery to the lower part of lung.

Our Service: Customized lactose for DPI

As DPI development is an interplay between inhalation device, API-properties and lactose carrier, a customized lactose which is tailored in particle size distribution, and surface property, may provide a competitive advantage, when the DPI-drug-development can be achieved in time and on target. Especially increasing the API’s fine particle fraction (FPF) through profound lactose carrier design and subsequently suffering less API loss can be a major improvement and marks successful drug commercialization.

MEGGLE has been active in this field for decades, and therefore has gained a tremendous amount of expertise, which the customer immediately benefits from. It is more than fair to say, that MEGGLE enabled successful products through its customized products for originators and generic companies alike.

Important: Highly controlled production processIn Dry Powder Inhalation (DPI) formulations, the excipient not only acts as a filler but also contributes to the performance features of the DPI. An extensive knowledge of the physico-chemical properties is a prerequisite to guarantee the functionality and safety of the DPI. This includes an established and well-investigated production process. All InhaLac® grades are produced via crystallization and subsequent sieving or milling. The optimized and standardized production process consistently ensures the highest production quality.

With our highly controlled production process different high quality grades for inhalation are obtained, providing an adequate range of particle.

MEGGLE´s lactose grades suitable for DPI are available under the trade names:

InhaLac® 70, InhaLac® 120, InhaLac® 140, InhaLac® 150, InhaLac® 160, InhaLac® 230, InhaLac® 251, InhaLac® 300, InhaLac® 400 and InhaLac® 500

MEGGLE has it. Lactose for powder preparations.

Although tablets account for the majority of solid oral dosage forms, powder preparations, such as capsules and sachets, present viable options to the developer.

In early stages of formulation development and preparation of clinical trial material, capsules are the ideal choice. When the preservation and long term integrity of the gelatin capsule is needed, lactose is the RIGHT choice! Lactose has limited interaction with gelatin capsules and is the ideal capsule filler for formulators around the world. This clearly has not changed for Hydroxypropylmethylcellulose (HPMC) capsules, which have gained a lot of popularity.

Capsules are of special interest for early stage developments and clinical trials medication, where on a final formulation has not been decided yet.

Trend: Capsule and sachet formulation for children and elderly people.

When developing a powder preparation, processability of the final powder blend, as well as content uniformity and avoiding powder segregation is imperative to a successful development. This is critical for pediatric and geriatric medicines. These patient populations represent a need for enhanced delivery methods that circumvent impaired tablet-swallowing. Capsules and sachets are trending as more popular dosages and offer opportunities for gaining market share.

Key for content uniformity: Suitable particle size distribution as well as bulk density.

MEGGLE has decided to contribute to these needs in a meaningful way by providing a range of lactose grades which differ in particle size distribution as well as bulk density. Both parameters are essential to a successful formulation development. With the right excipient technology choice, content uniformity issues may be a minor obstacle – MEGGLE has it! In order to provide consistent functionality, MEGGLE has implemented a rigorous quality system, which exceeds current Good Manufacturing Practice (GMP).

MEGGLE´s expertise: Off the shelf products or tailor-made sieved lactose grades.

As MEGGLE aims to achieve ultimate customer satisfaction, it has partnered with leading capsule-filling-machine-manufactures in order to provide expertise from both ends; material and processing. By partnering with these companies, MEGGLE is also able to tweak and improve its products, which leads to improved off-the-shelf products but gives the customers also the option to choose a tailor-made grade for even better performance.

MEGGLE´s sieved lactose grades offer great features in high speed capsule filling.

Maximum comfort using MEGGLE lactose in high speed capsule filling is guaranteed. Custom, powder-engineered sieved Lactose grades allow for balancing important powder properties such as density, flow or cohesiveness. In an extensive case study (AAPS 2019) using a MG2 Planeta dosator capsule filling machine,  material performance of a formulation comprising low dosage, ultrafine example API Vitamin B2 and coarse, lubricated lactose diluent SacheLac® 80 was investigated. Popular capsule sizes #1, #3, and #4 have been analyzed at 3 discrete filling speeds (15, 38, and 50k capsules/filling unit/h) at different time points according to content and weight uniformity and further performance-related parameters. All results indicated easy capsule filling at high efficiency and quality standards under given equipment design and compendial requirements.

MEGGLE lactose grades suitable for powder preparation e.g. high speed capsule and sachet filling are available under the trade names PrismaLac® 40, CapsuLac® 60, SacheLac® 80 and SpheroLac® 100.

Tablettose®, especially designed for Direct-Compression, combines the flowability of coarse lactose crystals and the good compressibility of fine milled lactose.

MEGGLEs Tablettose® 80 was the first available agglomerated alpha-lactose monohydrate of its kind. Its agglomerates possess a size ranging from 0 – 630 µm.

Tablettose® 70 is manufactured using identical starting material as Tablettose® 80; however, the particle size distribution is narrower. The content of fines smaller than 63 µm is reduced significantly and there are no particles larger than 500 µm, making Tablettose® 70 the excipient of choice for narrow particle size distribution and dust free production.

Tablettose® 100 is produced from a smaller starting particle size than the material used for Tablettose® 80 and Tablettose® 70. As a result, Tablettose® 100 has a higher dilution potential compared to Tablettose® 70 and Tablettose® 80 due to increased compactability.

FlowLac®

The product FlowLac® is produced by spray-drying a suspension of fine milled alpha-lactose monohydrate crystals in a solution of lactose. When lactose in solution is spray-dried, a rapid removal of water is taking place, whereby amorphous, non-crystalline lactose is formed in addition to crystalline lactose. Based on the amorphous content, kept on a stable level, non-varying better tabletting properties can be reached. Due to the spray-drying process, FlowLac® has a spherical agglomerate shape, consisting of small alpha-lactose monohydrate crystals bound by amorphous lactose.

FlowLac® 90 was developed to provide greater compactability compared to FlowLac®100 by optimizing the amorphous lactose content. In addition, the particle size distribution makes FlowLac® 90 virtually dust-free.

FlowLac® 100 is the standard grade for spray-dried lactose, which provides an excellent flowability and an extraordinary compactability compared to all other lactose grades.
