However, a <a href="//doi.org/10.1002/14651858.CD009583.pub2" class="extiw" title="doi:10.1002/14651858.CD009583.pub2">2014 Cochrane Systematic Review</a> concluded that from the included studies, there was limited evidence to demonstrate that "0.1 to 0.3<span class="nowrap"> </span>mg/kg nalbuphine compared to placebo might be an effective postoperative analgesic" for pain treatment in children.<sup id="cite_ref-:0_14-0" class="reference"><a href="#cite_note-:0-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> Further research is therefore needed to compare nalbuphine with other postoperative opioids.<sup id="cite_ref-:0_14-1" class="reference"><a href="#cite_note-:0-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> </p><p>Although nalbuphine possesses opioid antagonist activity, there is evidence that in nondependent patients it will not antagonize an opioid analgesic administered just before, concurrently, or just after an injection. Therefore, patients receiving an opioid analgesic, general anesthetics, phenothiazines, or other tranquilizers, sedatives, hypnotics, or other CNS depressants (including <a href="/wiki/Alcohol_(drug)" title="Alcohol (drug)">alcohol</a>) concomitantly with Nalbuphine may exhibit an additive effect. When such combined therapy is contemplated, the dose of one or both agents should be reduced. </p><p>In addition to the relief of pain, the drug has been studied as a treatment for morphine induced <a href="/wiki/Pruritus" class="mw-redirect" title="Pruritus">pruritus</a> (itching). Pruritus is a common side effect of morphine or other pure MOR agonist opioid administration. Kjellberg et al. (2001) published a review of clinical trials relating to the prevalence of morphine induced pruritus and its pharmacologic control. The authors state that nalbuphine is an effective anti-pruritic agent against morphine induced pruritus. The effect may be mediated via central nervous system mechanisms. </p><p>Pan (1998) summarizes the evidence that activation at the pharmacological level of the KOR antagonizes various MOR-mediated actions in the brain. The author states that the neural mechanism for this potentially very general MOR-antagonizing function by the KOR may have broad applications in the treatment of central nervous system mediated diseases. He does not state, however, that nalbuphine's pharmacological mechanism of action for pruritus is the result of this interaction between the two opioid receptors. </p><p>Morphine induced pruritus syndrome may also be caused by release of histamine from <a href="/wiki/Mast_cell" title="Mast cell">mast cells</a> in the skin (Gunion et al. (2004). Paus et al. (2006) report that MORs and KORs are located in skin nerves and keratinocytes. Levy et al. (1989) reviewed the literature on the relationship of opioid mediated histamine release from cutaneous mast cells to the etiology of hypotension, flushing and pruritus. The authors investigated the relative abilities of various opioids to induce histamine release mediated increased capillary permeability and tissue edema ("wheal response") and cutaneous vasodilatation and local redness ("flare response") when subjects were intradermally injected with 0.02 ml equimolar concentrations of 5 x 10-4 M. Nalbuphine did not produce either a wheal or flare response. </p> <div class="mw-heading mw-heading3"><h3 id="Available_forms">Available forms</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Nalbuphine&action=edit&section=2" title="Edit section: Available forms"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Nalbuphine is available in two concentrations, 10 mg and 20 mg of nalbuphine hydrochloride per mL.

This is particularly true for the side effects of nausea, sedation and cognitive symptoms (Jovey et al. 2003). These side effects can in many instances be ameliorated or avoided at the time of drug initiation by titrating the drug from a tolerable starting dose up to the desired therapeutic dose. An important difference between nalbuphine and the pure MOR agonist opioid analgesic drugs is the "ceiling effect" on respiration (but no ceiling on the analgesic effect). Respiratory depression is a potentially fatal side effect from the use of pure MOR agonists. Nalbuphine has limited ability to depress respiratory function (Gal et al. 1982). </p><p>As reported in the current Nubain Package Insert (2005), the most frequent side effect in 1066 patients treated with nalbuphine was sedation in 381 (36%). </p><p>Other, less frequent reactions are: feeling sweaty/clammy 99 (9%), nausea/vomiting 68 (6%), dizziness/vertigo 58 (5%), dry mouth 44 (4%), and headache 27 (3%).

Its analgesic potency is essentially equivalent to that of morphine on a milligram basis, which is based on relative potency studies using intramuscular administration (Beaver et al. 1978). Oral administered nalbuphine is reported to be three times more potent than codeine (Okun et al. 1982). Clinical trials studied single dose experimental oral immediate release nalbuphine tablets for analgesic efficacy over a four- to six-hour time period following administration. Nalbuphine in the 15 to 60 mg range had similar analgesic effects to immediate release codeine in the 30 to 60 mg range (Kantor et al. 1984; Sunshine et al. 1983). Schmidt et al. (1985) reviewed the preclinical pharmacology of nalbuphine and reported comparative data relative to other types of opioid compounds. The authors point out that the nalbuphine <a href="/wiki/Moiety_(chemistry)" title="Moiety (chemistry)">moiety</a> is approximately ten times more pharmacologically potent than the mixed opioid agonist/antagonist <a href="/wiki/Butorphanol" title="Butorphanol">butorphanol</a> on an "antagonist index" scale which quantitates the drug's ability to act both as an analgesic (via opioid KOR agonism) as well as a MOR antagonist. The opioid antagonist activity of nalbuphine is one-fourth as potent as <a href="/wiki/Nalorphine" title="Nalorphine">nalorphine</a> and 10 times that of <a href="/wiki/Pentazocine" title="Pentazocine">pentazocine</a>. </p> <div class="mw-heading mw-heading3"><h3 id="Pharmacokinetics">Pharmacokinetics</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Nalbuphine&action=edit&section=7" title="Edit section: Pharmacokinetics"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/Onset_of_action" title="Onset of action">onset of action</a> of nalbuphine occurs within 2 to 3 minutes after <a href="/wiki/Intravenous_administration" class="mw-redirect" title="Intravenous administration">intravenous administration</a>, and in less than 15 minutes following <a href="/wiki/Subcutaneous_injection" class="mw-redirect" title="Subcutaneous injection">subcutaneous</a> or <a href="/wiki/Intramuscular_injection" title="Intramuscular injection">intramuscular injection</a>.

Nalbuphine belongs to this group of substances. The mixed agonists-antagonists drug class exerts their analgesic actions by agonistic activity at the KOR. While all drugs in this class possess MOR antagonistic activity leading to less abuse potential, nalbuphine is the only approved drug in the mixed agonist–antagonist class listed in terms of its pharmacological actions and selectivities on opioid receptors as a MOR partial agonist or antagonist as well as a KOR agonist (Gustein et al. 2001). </p><p>Nubain was approved for marketing in the United States in 1978 and remains as the only opioid analgesic of this type (marketed in the U.S.) not controlled under the <a href="/wiki/Controlled_Substances_Act" title="Controlled Substances Act">Controlled Substances Act</a> (CSA). When the Controlled Substances Act (CSA) was enacted in 1971, nalbuphine was placed in <a href="/wiki/Controlled_Substances_Act#Schedule_II_controlled_substances" title="Controlled Substances Act">schedule II</a>. Endo Laboratories, Inc. subsequently petitioned the DEA to exclude nalbuphine from all schedules of the CSA in 1973.
