Pharmacologists are scientists who study how drugs interact with biological systems. They investigate the effects of medications on the body and how the body processes these substances. Their work helps in developing new drugs and improving existing ones, ensuring they are safe and effective for patients. These professionals often work in laboratories, conducting experiments and analyzing data. They may collaborate with other experts, such as physicians and biochemists, to understand the mechanisms of action of various drugs. Their research is crucial for advancing medical treatments and enhancing patient care in fields like pharmacy and medicine.
