What stimulants will stop respiratory depression with opiate usage without reversing the effects of analgesia such as when someone is using the CIS isomer of 3-methylfentanyl?
This now adds up to a comically large number of replies to a closed thread, but I'd like to note that classical stimulants do not reliably reverse respiratory depression caused by opioids or GABAnergic compounds. With opioids, you're better off using nalaxone (even with high-potency fentanyl analogues, though it won't be nearly as effective as with other opioids) and seeking medical attention.
