Which of the following does NOT qualify as legitimate medicinal use of ephedrine?

The use of ephedrine as a medicinal product is primarily regulated due to its potential for abuse and its associated health risks. In medical contexts, ephedrine is recognized for its legitimate therapeutic uses, such as acting as a decongestant, treating respiratory conditions like asthma, and managing hypotension (low blood pressure).

Enhancing physical performance, however, does not qualify as a legitimate medicinal use of ephedrine. This use implies an intention to improve athletic performance rather than to treat a medical condition. The practice of using ephedrine in this way is considered inappropriate and is often linked to doping in sports. Regulatory bodies typically classify such uses as non-therapeutic and potentially harmful, leading to strict guidelines against them.

In contrast, the other options reflect accepted medical applications backed by clinical evidence, making them legitimate uses of ephedrine.
