Manufacturing batch

Finally, we are in the business to produce products and profits. Broadly, if a product is made in 3-4 reaction steps in the batch-manufacturing environment, the market value should be 10 times the materials. If market value is only twice the raw material cost, the project should be redefined or stopped. In a 10-step process, it is not uncommon that materials are 1/20 of the selling price. A comparison of a two reaction step product using discounted cash flow methods (11) showed that a process with a market value 4 times the materials was greatly preferred over one at 3 times materials.

Quality and regulation are the most significant differentiators between the Pharmaceutical sector and the Specialty Chemical and Agrochemical sectors all of which employ the same basic production equipment and batch manufacturing techniques. 

Batch manufacture, storage, and transfer should be carried out in aeeordanee with routine procedures involving the same operators. The maehine should be eleaned and sterilized by the usual proeedures, although if an overkill sterilization eyele is used routinely, a partial sterilization (although still meeting standard parameters) may be chosen as worst case. ... 

The CIP and SIP cycle was performed according to the SOP and process was simulated according to the media fill batch manufacturing directions. The CIP, SIP, leak test, and process results of the freeze dryer for media fill run 1, run 2, and run 3 are found satisfactory. 

Organize these data in a chronological sequence according to batch manufacturing data, using a spreadsheet format. 

Materials. This section documents each component (raw materials, laminates, pouch stock, applicable lot/identifying numbers, etc.) used and the identifying numbers for each batch manufactured under the protocol. 

SOPs, environmental conditions and controls, and personnel common to batch manufacturing sites are used and where no changes are made to the manufacturing batch records except for administrative information and location of the facility. 

Establish process specifications. Once critical parameters and optimal conditions are defined and optimized, the process specifications must be established. The specifications become the targets to be met during batch-to-batch manufacture.
