Basics Of Aseptic Contract Manufacturing

While Aseptic Contract Manufacturing processes there are certain steps involved from choosing the right manufacturing company till the last step known as fill and finish. The ABC’s of the selection process involves the first step which is request for proposal called as the RFP in short. Along with the Contractor’s statement of work, agreement and the terms comes the manufacturing site visit, audit by the external team and the selection of the company. This visit is important in terms of the company reputation.

The RFP contains the description of the final drug product or the FDP and its final intended use. The complete product scope and the sequence followed during manufacturing. Special considerations, the end date of the FDP, the requirements for testing. The final stage would be shipping and billing details. It is said that the most common mistakes happen with the RFP. The Aseptic Contract Manufacturing companies may not understand the purpose of the RFP in proper. They might give minimal timeline for manufacturing the product and so on and here lies the real implication of the timeline and the contract.

Sterilization Guidelines by World Health Organization

The WHO has set some standards and codes for the companies in Aseptic Contract Manufacturing. These guidelines are very essential and they have to be followed for a better outcome. Quality control and sanitation, sterilization and terminal sterilization, Sterilization by filtration and aseptic processing, blow, fill and seal technology and finishing of sterile products. These are the basic guidelines set by the WHO. It is important that one abides by the norms of WHO to get into the depth of the issue.

Let us look into sterilization. Whenever it is possible all the products that are intended to be clean and sterile has to sterilize by heating. Any product that cannot be sterilized by heating such as the plastics and bags has to be sterilized by aseptic process or solutions. According to WHO guideline sterilization can be achieved by moist heating or radiation where heating is not possible. Sterilization has to be paid particular attention and validated. Aseptic manufacturing companies have a quality control team and they should not fail to do frequent inspection on the production area as well as the team. They should not fail to give an account of the things that are sterile and that needs to be changed.

Aseptic Sterilization Process

The operating conditions in aseptic processing are to prevent microbial contamination's of the products. The things that are to be taken into consideration during an aseptic processing are the environment, critical surfaces, personnel, containers, closure and transfer procedures, maximum holding period before filling the end product in the container and the filter. Solutions can be filtered using a filter of normal pore size of 0.22 micron or less as they cannot be sterilized using heat or radiation. The sterilized filter has to be checked before and after use to ensure integrity of the filter. This is sure to make the process easier.
