Which controlled substance is a combination of Chlorpheniramine with Hydrocodone?

Tussionex is a combination cough medication that contains Chlorpheniramine, an antihistamine, and Hydrocodone, which is an opioid used for cough suppression. This combination works effectively to alleviate cough and alleviate allergy symptoms. The presence of Chlorpheniramine helps reduce histamine-related symptoms like sneezing and runny nose, while Hydrocodone provides relief from persistent cough by acting on the cough center in the brain.

In contrast, Vesicare is primarily used to treat overactive bladder and does not contain either Chlorpheniramine or Hydrocodone. Januvia is an antidiabetic medication used for managing blood sugar levels in type 2 diabetes and is not related to cough suppression or allergy treatment. Mirapex is indicated for the treatment of Parkinson’s disease and restless legs syndrome, and also does not involve the components listed in the question. Therefore, Tussionex is the clear and correct choice as it accurately describes the combination of the two substances specified.
