Receiving raw materials is not only about unloading cartons from a vehicle. One of the first and most important GMP activities is verifying the Delivery Challan (DC) and Invoice before accepting the shipment. Many warehouse deviations, inventory mismatches, payment disputes, and audit observations start because these documents were not checked properly. A warehouse person should […]
Introduction Every medicine reaches the patient safely because of two important things—the quality of the product and the quality of its packaging. Even if a tablet or injection is manufactured perfectly, damaged cartons, incorrect labels, defective bottles, or mixed packaging materials can lead to product recalls, regulatory observations, and patient safety risks. That is why
Every pharmaceutical product begins with raw materials and packaging materials received from suppliers. Even if a supplier is approved, every delivery must be carefully verified before unloading. A single damaged truck, incorrect batch, or broken seal can compromise product quality and patient safety. This is why Vendor Delivery Verification During Material Receipt is one of
Introduction If you’ve ever swallowed a tablet, you’ve probably noticed that it starts working after a certain amount of time. But have you ever wondered what makes a hard compressed tablet break apart quickly once it reaches the stomach? The answer is disintegrants. During my experience in pharmaceutical manufacturing, one of the most common in-process
Introduction If you’ve ever worked in a pharmaceutical granulation area, you’ve probably noticed that the active pharmaceutical ingredient (API) is often only a small part of the total tablet weight. The remaining portion is made up of excipients, and among them, diluents play one of the most important roles. Early in my experience working around
Introduction If you have ever worked in a tablet manufacturing area, you know that even a perfectly prepared granule can create serious problems during compression if lubrication is not done correctly. Tablets may stick inside the die, punches may wear quickly, tablet hardness may drop, or dissolution may fail. In many cases, the root cause
Pressure differential is one of the most important environmental controls in a pharmaceutical dispensing area. It helps control the movement of air between rooms and reduces the risk of dust, cross-contamination, and contamination of raw materials. In daily pharmaceutical operations, Pressure Differential in Dispensing Area may look like a small parameter displayed on a Magnehelic
In pharmaceutical manufacturing, uniform mixing of powders and granules is very important. A tablet may contain several ingredients, including API, diluents, disintegrants, glidants, and lubricants. These materials must be distributed uniformly before compression or capsule filling. The Double Cone Blender is one of the commonly used powder blending machines in the pharmaceutical industry. It is
A Vibro Sifter is one of those machines that looks simple from the outside but plays an important role in pharmaceutical manufacturing. Anyone who has worked in a dispensing area, granulation section, or material handling area has probably seen a Vibro Sifter being used for sifting raw materials, dried granules, or other pharmaceutical powders. The
In pharmaceutical manufacturing, reducing the size of materials is a common activity. Granules may become too large after drying, powders may contain lumps, and sometimes a material must be resized before it can move to the next manufacturing stage. One commonly used machine for this purpose is the Multi Mill. A Multi Mill is used
