| |
− |
| |
− | == Pharmacology ==
| |
− |
| |
− | Hydromorphone molecules exert their effects by binding to and activating the μ-opioid receptor as an agonist. This occurs due to the way in which opioids structurally mimic [[endogenous]] endorphins. Endorphins are responsible for analgesia, sedation, and cognitive euphoria along with physical euphoria. They can be released in response to pain, strenuous exercise, orgasm, or excitement. This mimicking of natural endorphins results in the drug's euphoric, [[analgesic]], and [[anxiolytic]] effects.
| |
− |
| |
− | The recreational effects of this compound, including cognitive euphoria and physical euphoria, occur because opioids structurally mimic [[endogenous]] endorphins which are naturally produced within the body and are also active on the μ-opioid receptor set in the brain. The way in which synthetic opioids such as heroin structurally mimic these natural endorphins results in their euphoric, pain relief and [[anxiolytic]] effects. This is because natural endorphins are responsible for reducing pain, causing sedation, and feelings of pleasure. The natural endorphins can be released in response to pain, strenuous exercise, orgasm, or general excitement <ref name="1046"/>.
| |
− |
| |
− | === Pharmacodynamics ===
| |
− |
| |
− | Hydromorphone is a hydrogenated ketone derivative of morphine that acts as a narcotic analgesic. It has a shorter duration of action than morphine. Hydromorphone is approximately 8 times more potent on a milligram basis than morphine. In addition, hydromorphone is better absorbed orally than is morphine. In clinical settings, Hydromorphone exerts its principal pharmacological effect on the [[central nervous system]] and gastrointestinal tract. Its primary actions of therapeutic value are analgesia and sedation. Hydromorphone appears to increase the patient's tolerance for pain and to decrease discomfort, although the presence of the pain itself may still be recognised. In addition to analgesia, alterations in mood, euphoria and dysphoria, and drowsiness commonly occur. Opioids also produce respiratory depression by direct action on brain stem respiratory centres <ref name="1055"/>.
| |
− |
| |
− | === Absorption ===
| |
− |
| |
− | Better absorbed orally than morphine <ref name="1055"/>.
| |
− |
| |
− | === Bioavailability ===
| |
− |
| |
− | Oral 51.35% +/- 29.29%, insufflated 52.4%, rectal 36.33% +/- 29.6% <ref name="1051"/>.
| |
− |
| |
− | === Metabolism ===
| |
− |
| |
− | Primarily hepatic. After absorption hydromorphone is metabolised by the liver to the glucuronide conjugate which is then excreted in the urine. Hydromorphone is metabolised to the major metabolites hydromorphone-3-glucuronide, hydromorphone-3-glucoside and dihydroisomorphine-6-glucuronide <ref name="1055"/>.
| |
− |
| |
− | === Half-life ===
| |
− |
| |
− | 2.6 hours (oral); 18.6 hours for sustained release Palladone <ref name="1055"/>.
| |
− |
| |
− | === Elimination ===
| |
− |
| |
− | Only a small amount of the hydromorphone dose is excreted unchanged in the urine. Most of the dose is excreted as hydromorphone-3-glucuronide along with minor amounts of 6-hydroxy reduction metabolites <ref name="1055"/>.
| |
− |
| |
− | === Lethal dosage ===
| |
− |
| |
− | 2.9191 [[LD50]] mol/kg in rats <ref name="1055"/>.
| |
− |
| |
− | === Toxicity ===
| |
− |
| |
− | Hydromorphone is a schedule II narcotic which can lead to physical dependence or addiction <ref name="1055"/>.
| |
− |
| |
− | === Tolerance ===
| |
− |
| |
− | Tolerance to many of the effects of hydromorphone develops with prolonged use, including therapeutic effects. This results in users having to administer increasingly large doses to achieve the same effects. The rate at which this occurs develops at different rates for different effects with tolerance to the [[constipation]]-inducing effects developing particularly slowly <ref name="1046"/>.
| |
− |
| |
− | === Mechanism of action ===
| |
− |
| |
− | Hydromorphone is a narcotic analgesic; its principal therapeutic effect is relief of pain. Hydromorphone interacts predominantly with the opioid mu-receptors. These mu-binding sites are discretely distributed in the human brain, with high densities in the posterior amygdala, hypothalamus, thalamus, nucleus caudatus, putamen, and certain cortical areas. They are also found on the terminal axons of primary afferents within laminae I and II (substantia gelatinosa) of the spinal cord and in the spinal nucleus of the trigeminal nerve. In clinical settings, Hydromorphone exerts its principal pharmacological effect on the [[central nervous system]] and gastrointestinal tract. Hydromorphone also binds with kappa-receptors which are thought to mediate spinal analgesia, [[miosis]] and [[sedation]] <ref name="1055"/>.

| |
− |
| |
− | == Dangerous interactions ==
| |
− |
| |
− | Hydromorphone is dangerous to use in combination with other depressants as many fatalities reported as overdoses are caused by interactions with other depressant drugs like alcohol or benzodiazepines, resulting in dangerously high levels of respiratory depression <ref name="1047">Darke, S. and Zador, D., '''Fatal heroin 'overdose': a review''', ''Addiction'', 1996, 91, 12, 1765-1772, https://doi.org/10.1046/j.1360-0443.1996.911217652.x, http://www.ncbi.nlm.nih.gov/pubmed/8997759</ref>, <ref name="1046"/>.
| |
− |
| |
− | * '''Depressants (1,4-Butanediol, 2m2b, [[alcohol]], barbiturates, benzodiazepines, [[GBL / GHB]], methaqualone)''' - This combination can result in dangerous or even fatal levels of respiratory depression. These substances potentiate the muscle relaxation, sedation and amnesia caused by one another and can lead to unexpected loss of consciousness at high doses. There is also an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
| |
− | * '''Dissociatives''' - This combination can result in an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
| |
− | * '''Stimulants''' - It is dangerous to combine hydromorphone, a depressant, with stimulants due to the risk of excessive intoxication. Stimulants decrease the sedative effect of hydromorphone, which is the main factor most people consider when determining their level of intoxication. Once the stimulant wears off, the effects of hydromorphone will be significantly increased, leading to intensified disinhibition as well as other effects. If combined, one should strictly limit themselves to only taking a certain amount of hydromorphone. Some stimulants may also lower the seizure threshold.
| |
− | * '''Monoamine oxidase inhibitors''' - There have been rare cases of serotonin syndrome when opioids are used with monoamine oxidase inhibitors <ref name="1048">Mateo-Carrasco, H. and Muñoz-Aguilera, E. M. and García-Torrecillas, J. M. and Abu Al-Robb, H., '''Serotonin syndrome probably triggered by a morphine-phenelzine interaction''', ''Pharmacotherapy'', 2015, 35, 6, 102-105, https://doi.org/10.1002/phar.1581, https://www.ncbi.nlm.nih.gov/pubmed/25903219</ref>, <ref name="1049">Gillman, P. K., '''Monoamine oxidase inhibitors, opioid analgesics and serotonin toxicity''', ''British Journal of Anaesthesia'', 2005, 95, 4, 434-441, https://doi.org/10.1093/bja/aei210, https://www.ncbi.nlm.nih.gov/pubmed/16051647</ref>. This has also been reported with other drugs that increase extracellular serotonin like selective serotonin reuptake inhibitors <ref name="1050">Karunatilake, H. and Buckley, N. A., '''Serotonin syndrome induced by fluvoxamine and oxycodone''', ''Annals of Pharmacotherapy'', 2006, 40, 1, 155-157, https://doi.org/10.1345/aph.1E671, https://www.ncbi.nlm.nih.gov/pubmed/16368927</ref>, <ref name="1046"/>.
| |
− |
| |
− | === Dangerous ===
| |
− |
| |
− | * '''[[Ketamine]]''' - Both substances bring a risk of vomiting and unconsciousness. If the user falls unconscious while under the influence there is a severe risk of vomit aspiration if they are not placed in the recovery position.
| |
− | * '''[[MXE]]''' - This combination can potentiate the effects of the opioid.
| |
− | * '''[[DXM]]''' - [[CNS]] depression, difficult breathing, heart issues, hepatoxic, just very unsafe combination all around. Additionally if one takes [[dxm]], their tolerance of opiates goes down slightly, thus causing additional synergistic effects.
| |
− | * '''[[Cocaine]]''' - Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
| |
− | * '''[[Alcohol]]''' - Both substances potentiate the [[ataxia]] and [[sedation]] caused by the other and can lead to unexpected loss of consciousness at high doses. Place affected patients in the recovery position to prevent vomit aspiration from excess. Memory blackouts are likely.
| |
− | * '''[[GBL / GHB]]''' - The two substances potentiate each other strongly and unpredictably, very rapidly leading to unconsciousness. While unconscious, vomit aspiration is a risk if not placed in the recovery position
| |
− | * '''[[Tramadol]]''' - Concomitant use of [[tramadol]] increases the seizure risk in patients taking other opioids. These agents are often individually epileptogenic and may have additive effects on seizure threshold during coadministration. Central nervous system- and/or respiratory-depressant effects may be additively or synergistically present.
| |
− | * '''Benzodiazepines''' - Central nervous system and/or respiratory-depressant effects may be additively or synergistically present. The two substances potentiate each other strongly and unpredictably, very rapidly leading to unconsciousness. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Blackouts/memory loss likely <ref name="1051"/>.
| |
− |
| |
− | === Caution ===
| |
− |
| |
− | * '''[[PCP]]''' - [[PCP]] can reduce opioid tolerance, increasing the risk of overdose.
| |
− | * '''[[Nitrous oxide]]''' - Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Memory blackouts are likely.
| |
− | * '''Amphetamines''' - Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
| |
− | * '''MAOIs''' - Coadministration of monoamine oxidase inhibitors (MAOIs) with certain opioids has been associated with rare reports of severe and fatal adverse reactions. There appear to be two types of interaction, an excitatory and a depressive one. Symptoms of the excitatory reaction may include agitation, headache, diaphoresis, hyperpyrexia, flushing, shivering, myoclonus, rigidity, tremor, diarrhoea, hypertension, [[tachycardia]], seizures, and coma. Death has occurred in some cases <ref name="1051"/>.
