Broadly speaking, pharmaceutical technologies are methods and/or devices used to produce, monitor, or control drug substances and/or dosage forms. This can include everything from individual production steps (e.g. milling, granulation) to complete production lines and packaging lines.
In recent years, there has been a significant focus on developing innovative technologies that can help improve patient outcomes and/or reduce healthcare costs. For example, technologies such as 3D printing and nanotechnology are being explored as potential methods for improving drug delivery and/or reducing the cost of drug development and manufacture.
If you're interested in learning more about pharmaceutical technologies, there are a number of good resources available online. The Pharmaceutical Manufacturing Encyclopedia is a good starting point, and the FDA's website also has a lot of useful information.
