What is the hand-filling method for capsules called where the powder is punched into the capsule?

The hand-filling method for capsules where the powder is punched into the capsule is known as the Punch Method. This technique involves using a clean, blunt object to compress the powder into the capsule, allowing for a denser packing of the material and minimizing air gaps. The process typically involves filling one half of the capsule with powder and then using the punch to pack down the contents before closing the capsule.

This method is particularly useful when dealing with powders that are difficult to flow or when a precise dosage is required. By punching the powder into the capsule, the technician can maximize the amount of medication that fits into the capsule while ensuring that it is compact and uniform.

Other methods such as the Pour Method involve simply pouring the powder into the capsule without significant compression, which could lead to a less dense fill and potential inconsistencies in dosage. The Shake Method often refers to shaking the capsule to help settle the powder, but it does not achieve the same level of compaction as the Punch Method. The Displacement Method is not typically referred to in standard capsule filling terminology and may relate to a different process in pharmaceutical practice. Thus, the Punch Method is indeed the correct term for the described technique.
