90mg hydrocodone, 30mg temazepam, 2mg clonazepam, 30mg cyclobenzaprine, and the following potentiators: 150mg clotrimazole, 500mg ciprofloxacin, 800mg cimetidine, large amount of grapefruit juice, 150mg diphenhydramine, and 300mg daily bupropion/Wellbutrin (prescribed for depression/Bipolar disorder). I feel like I have had more like 150mg+ hydrocodone.
About to smoke some weed.
Hydrocodone is metabolized mostly by CYP-450 3A4 but also by 2D6 (at least from the information I have gathered).
Clotrimazole is a strong or moderate inhibitor of 3A4, cipro is either a moderate or strong 3A4 inhibitor, cimetidine is a weak 3A4 and 2D6 inhibitor, bupropion is a strong 2D6 inhibitor, and grapefruit juice contains a moderate 3A4 inhibitor. This is how strong, moderate, and weak inhibitors are defined:
A strong inhibitor being one that causes at least a 5-fold increase in the plasma AUC values, or more than 80% decrease in clearance.
A moderate inhibitor being one that causes at least a 2-fold increase in the plasma AUC values, or 50-80% decrease in clearance.
A Weak inhibitor being one that causes at least a 1.25-fold but less than 2- fold increase in the plasma AUC values, or 20-50% decrease in clearance.
I don't think all drugs metabolized by these enzymes are affected as strongly though.
I have seen conflicting info on whether Cipro is of strong or moderate strength - some lists do not specify its strenght but I read a study showing a significant increase in side effects such as respiratory depression when taken with hydrocodone. Oral clotrimazole+hydrocodone is listed as a major interaction with the drug interaction checker and is in a class of drugs that contain a number of strong and moderate 3A4 inhibitors.
I took most of the inhibitors at least an hour before the hydrocodone. It makes the effects much stronger and much longer lasting. Diphenhydramine and many other antihistimines increase the effectiveness of opiates by 15-30%. You can get clotrimazole OTC - it is in cream for athlete's foot and nail fungus. Whether or not you are willing to eat cream meant to be applied externally is up to you.
For best results potentiating hydrocodone, you probably want to combine a strong 3A4 inhibitor with a strong 2D6 inhibitor if the drug interaction checker is correct, but strong 2D6 inhibition may decrease effects by slowing or stopping conversion to hydromorphone. Maybe the best way to do this is to inhibit 3A4 as completely as possible and not worry about 2D6 (but I need Wellbutrin/bupropion, so I can only try quitting it a few days then seeing if things work better with everything but the 2D6 inhibitors) and an antihistimine. Adding UGT2B7 inhibitors will possiblyly increase the effects noticeably by slowing breakdown of the active metabolite hydromorphone which may be responsible for nearly half of hydrocodone's effects.
I could be wrong. 3A4 inhibition keeps hydrocodone from being metabolized as fast and increases peak levels (not sure if all inhibitors help) but this slows conversion to hydromorphone. In one place I read over, it says maybe about 53% of the effects of hydrocodone are from hydrocodone itself and about 46% from the active metabolite hydromorphone (I do not know how accurate that info is due to the source) and that 2D6 inhibition prevents hydrocodone from being metabolized to norhydrocodone but that is a drug forum website and a scientific study says it is the other way around. Here is where I read that above info:
https://www.drugs-forum.com/forum/showthread.php?t=236374
I'll go by a scientific study which seems more reliable and the information seems more like what I have read in the past. The study says 2D6 is responsible for converting it to hydromorphone and it is 3A4 that metabolizes it to norhydrocodone, a very weak opioid. The scientific study says hydromorphone only contributes modestly to the effects of hydrocodone.It is over the topic of conversion to hydromorphone and 2D6 enzyme. It said adding a strong 2D6 inhibitor, quinidine, produced just minor and inconsistent effects and hydromorphone contributes only slightly to hydrocodone's abuse potential.

But then I see what seems to be a professional source saying hydrocodone is metabolized completely by 2D6 - does not seem to be the case from many other sources, all that disagree - all others say 3A4 and 2D6 are involved.
Hydromorphone can be potentiated with UGT2B7 inhibitors. I only see four listed here: Ketoconazole (also a strong CYP450-3A4 inhibitor), Valproic acid, Silybum marianum, and Valerian root:

Maybe the best way is a strong and multiple moderate and weak inhibitors of 3A4 to inhibit the enzyme as fully as possible and maybe a weak or moderate 2D6 inhibitor since your hydrocodone levels should be high much longer and 0 you won't need to convert that to hydromorphone very fast. Adding UGT2B7 inhibitors might help and I am going to try it.
