Zenith Pharma has maintained pharmaceutical standards with our Finex®22 for over 17 years
Getting the right particle size for active pharmaceutical ingredients (API) is essential for ensuring medicines are safe, effective and meet regulatory requirements. Controlling particle size improves the flow of powders and ensures an even mix. This ensures each tablet or capsule contains the right dose. That’s why pharmaceutical manufacturer, Zenith Pharma chose to invest in our Finex® 22 when sieving their API powder.
Zenith Pharma is a leading pharmaceutical manufacturer and distributor in Morocco, manufacturing over 200 product families. Their broad range includes branded and non-branded medicines, dietary supplements, medical devices, and advanced dermo-cosmetic solutions.
The production process for Zenith Pharma’s products begins with active pharmaceutical ingredients which undergo control sieving to ensure a uniform particle size. These refined materials then move through mixing and granulation stages before compression into tablets, capsules or filling liquid medicines.
The challenge with API sieving
Zenith Pharma needed to prove to regulators that they could consistently prevent contamination through sieving and granulation. To meet these strict requirements, the company needed an accurate and reliable sieving solution to support the validation process before releasing products to the market.
This was a critical step given the risks associated with poor API sieving. Ineffective or inadequate sieving may allow foreign contaminants such as metal fragments, fibers, or oversized particles to remain in the powder. This compromises product safety and potentially leads to regulatory non-compliance.
Additionally, inconsistent particle size can negatively affect downstream processing, resulting in poor blend uniformity, reduced product quality and performance. These inconsistencies cause validation failures as processes rely on tightly controlled particle specifications. This can lead to batch rejection, increased waste, higher production costs and damage to company reputation due to poor product quality or customer complaints.
The solution to API sieving
Having previously used our industrial sifters at other organizations, Zenith Pharma invested in our Finex®22 in 2009 and is still using the same machine today. Our equipment operates with a wide range of mesh sizes including 1000, 800, 630, 250, and 100 microns to ensure high‑precision processing. This flexibility allows Zenith Pharma to select the exact level of granulation or control sieving required meeting the stringent validation requirements required for product release.
During the granulation stage, powder can be humid, so sieving is completed in batches of up to 80 kilograms. However, when the powder is dry, batch sizes are increased to up to 140 kilograms, before compression.
When our Finex® 22 is dedicated to a single product and operated continuously, there is no need to interrupt production for cleaning. Cleaning is only required during product changeovers to prevent cross-contamination, resulting in significant time and cost savings for the manufacturer.
What our customers say
Russell Finex is well known in Morocco for their sieving equipment, which is trusted by many pharmaceutical companies. I had a very positive personal experience of using their machines in the 1990s, so I knew we needed a Russell Finex machine to support the production of our own medicines. The accuracy of Russell Finex equipment is essential to our ability to manufacture and supply medicines. Our machine is highly reliable and performs consistently around the clock, giving us complete confidence 24/7.
