Pharmacologists usually work in laboratories at universities, hospitals, pharmaceutical companies, biotechnology organisations, or in some government departments or regulatory agencies. Their work is conducted in sterile, controlled environments to prevent contamination and ensure that observed effects are directly attributable to the drug under study. 

Pharmacologists must keep detailed records of all their work to demonstrate that research and testing has been thorough and to ensure that results can be replicated. They usually work standard business hours, however evening and weekend work may be required particularly when working to a deadline.

Pharmacologists employ advanced medical and laboratory equipment to collect and analyse samples from test subjects. They may study blood, urine and tissue samples to assess a drug’s effectiveness in treating disease and to track how it moves through the body.

To maintain sterile conditions and protect against potentially hazardous substances, they often wear protective clothing such as gloves, masks, safety glasses, lab coats and hair nets.
