Pharmaceutical engineering
Pharmaceutical engineering applies engineering principles to design, develop, scale up, and manufacture medicines and the processes that produce them.
Drug formulation: The process of combining active pharmaceutical ingredients with excipients to create a usable medicine. Formulation choices determine the product properties that manufacturing processes must reliably deliver.
Chemical engineering: The engineering discipline concerned with transforming materials through chemical, physical, and biological processes. Its transport, reaction, and process-design methods underpin much pharmaceutical production.
Tablet: A solid dosage form containing one or more medicines, usually made by compression of powder or granules. Tablet production combines formulation, granulation, drying, and compression at manufacturing scale.
Pharmaceutical quality by design: A systematic development approach that builds quality into a product and process through scientific understanding and risk management. It links process design decisions to measurable product quality rather than relying only on end testing.
Pharmaceutical process development: The design and refinement of processes for producing pharmaceutical products at specified quality. It translates a candidate formulation into a workable, controlled production process.
Pharmaceutical technology: The science and practice of developing dosage forms and the technologies used to manufacture them. It supplies the dosage-form knowledge that engineering turns into production operations.
Sterile manufacturing: The production of medicines under conditions designed to prevent microbial contamination. Injectable medicines require tightly engineered aseptic processes and contamination controls.
Process validation: Documented evidence that a process can consistently produce output meeting predetermined quality requirements. Scale-up and routine production require evidence that the designed process performs reproducibly.
Scale-up: The transfer of a process from small-scale operation to larger production while managing changes in performance. Equipment, mixing, heat transfer, and material behavior can change as production grows.
Pharmaceutical excipient: An ingredient in a medicine other than its active pharmaceutical ingredient, included for functions such as stability or delivery. Excipient properties affect processability, product performance, and manufacturing consistency.
