Which of the following are brand names of Desvenlafaxine?

Desvenlafaxine is an antidepressant that belongs to the serotonin-norepinephrine reuptake inhibitor (SNRI) class. The brand name specifically associated with Desvenlafaxine is Pristiq. Khedezla is also a brand name for Desvenlafaxine, making the combination offered in this choice correct.

In contrast, the other options contain incorrect or unrelated medications. For instance, Effexor is a brand name for venlafaxine, which, although closely related to Desvenlafaxine in terms of pharmacological action, is not the active ingredient in this scenario. Sertraline and fluvoxamine are both selective serotonin reuptake inhibitors (SSRIs), which belong to a different class of antidepressants altogether. Their inclusion fails to connect with Desvenlafaxine, clarifying why they cannot be appropriate answers in this context.

By identifying Pristiq and Khedezla as brand names of Desvenlafaxine, the correct choice captures the essential connection to the medication, affirming the importance of understanding medication branding in pharmacology.
