For example, pharmacists can extract active ingredients from flowers, leaves, roots and other plants and try to convert them into drugs. Pharmacists can also use chemical synthesis technology to prepare new drugs by artificially synthesizing chemicals. Pharmacists also need to learn the knowledge of drug preparation methods, drug compatibility and medication methods to ensure the safety and effectiveness of patients' medication.
Pharmacy plays an important role in the medical field. Pharmaceutics not only helps people better understand the action principle of drugs, but also makes the production and synthesis of drugs more standardized and safe.
