Which of the following is true about trade name drugs?

Trade name drugs, also known as brand name drugs, refer to the proprietary names given to medications by their manufacturers. This naming convention is designed to distinguish a particular formulation from others on the market. The trade name is typically selected for its marketing appeal, aiming to be catchy or memorable to both healthcare providers and consumers. Unlike generic names, which are based on the active ingredient and follow a more standardized naming convention, trade names can vary considerably in their structure and length.

The other options address aspects related to drug naming but do not accurately describe trade name drugs. For example, trade names do not follow the rule of being written in lowercase; they are officially capitalized to signify their status as a brand. Additionally, trade names are not necessarily longer or harder to pronounce, as they are often designed to be more accessible compared to the chemical names or generic names, which can be quite complex.
