You are in safe hands

Many small-molecule pharmaceuticals cannot be terminally sterilized using heat or irradiation, requiring aseptic manufacturing processes. Highly-potent molecules may also call for specialist handling requirements within a containment environment.

Small molecule drugs

Generally defined as having a molecular mass of fewer than 900 Daltons, the majority of pharmaceuticals are classified as small molecule drugs. These are frequently administered orally for absorption through the stomach or intestine, but can also be administered topically, through inhalation, or via parenteral injection.


Small molecule drugs are often tolerant to terminal sterilization, and may not require an aseptic manufacturing approach if administered parenterally. However, many small molecules cannot tolerate terminal sterilization by heat or irradiation, requiring aseptic manufacturing.
