What term denotes drugs created using man-made chemicals instead of natural ingredients?

The term that indicates drugs created using man-made chemicals, rather than those sourced from natural ingredients, is "synthetic drug." Synthetic drugs are specifically formulated in laboratories, utilizing chemical processes to create substances that may mimic the effects of naturally occurring drugs or may have entirely new effects not found in nature. This distinction is important as synthetic drugs can often have different properties, effects, and risks compared to their natural counterparts, including variations in potency, side effects, and potential for addiction.

In contrast, the other terms refer to drugs that derive from natural sources. "Organic drug" typically refers to substances that are made from organic materials but does not necessarily imply synthetic processes, while "natural drug" indicates substances extracted directly from plants, animals, or minerals without alteration. "Herbal drug" specifically pertains to medications derived from plant materials. Thus, synthetic drugs stand out due to their creation through artificial chemical processes.
