Cheratussin AC and pain relief

I find that this medication (Cheratussin AC) is less effective than Tussionex. I believe that the hydrocodone component in Tussionex is more influential and efficacious on the respiratory system than the otolaryngological effects produced by codeine. Codeine, surprisingly, is less potent, in my experience, than hydrocodone. One would expect that codeine would yield more beneficial effects concerning pain relief and cough suppression, as opposed to a more distant relative of morphine, such as hydrocodone. It's interesting how medication affects physiological functioning. This medication, though, generally creates sides effects that are fatigue-oriented, including drowsiness, decreased energy or enervation, and related somnolence symptoms.
