Because the nasal bioavailability of hydrocodone was not known, a subset of subjects completed a dose selection phase to identify an appropriate intranasal dose of hydrocodone powder that would result in sufficient differentiation on a subjective measure of drug liking between placebo and hydrocodone.
Negative urine drug screen results were required prior to administering the naloxone challenge and all subsequent treatments. Moderate experience was defined as opioid use for nontherapeutic purposes (i.e., for psychoactive effects) on at least 10 occasions in the previous year, with use of opioids ≥three times in the 12 weeks prior to screening, and ≥three occasions of intranasal opioid use for recreational abuse purposes in the past year. Study subjects were healthy, moderay experienced opioid users aged 18–55 years with a history of intranasal opioid abuse.
Where did the author get their information about the nasal bioavailability of hydrocodone? jacob. Thursday, January 22nd, 2015. This helped me in no way, as the answers given are false. I know, due to experience. I generally sniff 3 10/325 hydros a day. The high last over 2 hours, the pain killing affects last.
Snorting hydrocodone allows the psychoactive agent to enter the bloodstream more quickly than oral administration. By comparison, it can take thirty minutes for hydrocodone to work orally, because it has to be digested and pass through the intestinal wall to enter the bloodstream. In general, this method of administration is faster and more intense…but the drug’s action will usually wear off quicker.
Snorting hydrocodone allows the drug to get into the body faster. Many people ignore the risks of overdose because snorting hydrocodone is effective in speeding up not only the analgesic effect of hydrocodone, but also induces a euphoric high.
Methods: Subjects (N = 42) in Part B received five in-clinic treatments consisting of intranasal and oral benzhydrocodone/APAP (13.34/650 mg), intranasal and oral hydrocodone/APAP (15/650 mg), and placebo, with four or more days of washout between treatments.

Hydrocodone Cmax was 11% lower for intranasal benzhydrocodone/APAP vs intranasal HB/APAP (P = 0.0027). Early cumulative hydrocodone exposures for intranasal benzhydrocodone/APAP through 0.5, 1, and 2 hours were reduced by approximay 50%, 29%, and 15%, respectively (P ≤ 0.0024). Adverse nasal effects were more frequent for intranasal benzhydrocodone/APAP vs intranasal HB/APAP.
It lists every major opiate with it’s half-life and bioavailability for Oral, IM, IV, Rectal and Intranasal administration. 13 thoughts on “Opiate Bioavailability Chart”. Your chart shows greater BA of Oxycodone orally vs intranasal ( 87% vs 50% ).
You can check this chart and figure out the most effect way to take it. It lists every major opiate with it’s half-life and bioavailability for Oral, IM, IV, Rectal and Intranasal administration. This is a little projected I did a while back. It’s definiy a useful little tool when you find yourself with some opiate your aren’t familiar with and you want to get the most bang for you buck.
Background and Objective: Narcotic analgesics such as hydromorphone undergo an extensive first-pass effect resulting in a low systemic bioavailability following oral administration. Alternative dosing routes, such as rectal and intranasal (IN) routes, have been suggested as options for oral or intravenous administration.
