The antonyms for the term "medical practitioner" can encompass several words depending on the context. For instance, if we consider the opposite of a medical practitioner who directly interacts and treats the patients, then a non-medical practitioner might be an appropriate antonym. Similarly, a non-specialist, non-expert or non-qualified individual may also serve as an antonym. If we talk about the roles, nurses, physicians' assistants, pharmacists, physiotherapists, and other licensed medical professionals could be considered antonyms. However, it is crucial to note that antonyms for medical practitioners may vary from one instance to another, depending on the specific subfield or aspect of healthcare in question.
