In addition, there is a high risk of precipitating acute opioid withdrawal in an individual who is physically dependent on opioids. Opioid antagonists should be avoided in the absence of clinically significant respiratory or circulatory depression. The opioid antagonists, nalmefene or naloxone, are specific antidotes for respiratory depression. In case of overdose, the first step is to protect the airways and place the patient on invasive ventilation assistance, if needed.

Hydrocodone intake may lead to life-threatening respiratory depression, especially if taken together with benzodiazepines or other CNS depressants. For patients presenting for 4 hours or later, the serum acetaminophen level should be obtained promptly. In overdose, activated charcoal should be the first attempted intervention before N-acetylcysteine (NAC). Furthermore, large doses may cause difficulty with breathing. Īcetaminophen has been associated with fatal hepatic necrosis if taken at doses more than 4 g per day, especially with the ingestion of another acetaminophen-containing product. Also, opioid-induced hyperalgesia is a recently recognized phenomenon after patients experienced increasing pain despite increasing doses of opioids.

Opioid users also suffer from endocrine changes in the body, including but not limited to sexual dysfunction, depression, and decreased energy levels, resulting from hypogonadotropic hypogonadism. As a result, there are implications of opioids, pointing to an increased incidence of infections in subjects with heroin use disorder.

Moreover, acute and chronic opioid administration can inhibit antibody and cellular immune responses, natural killer cell activity, cytokine expression, and phagocytic activity. Īs with all opioids, tolerance leading to ever-increasing doses of opioids to maintain the same level of pain control and physical dependence is the most common side effect. There have been reports of progressive sensorineural hearing loss with chronic hydrocodone/acetaminophen use that is not responsive to high-dose steroids but responsive to cochlear implantation. Opioid-induced constipation, dizziness, nausea, vomiting, drowsiness, and respiratory depression are common adverse reactions of hydrocodone-acetaminophen medication. Approximately 85% of the drug is eliminated in the urine within 24 hours of administration. The plasma half-life ranges from 1 to 3 hours however, it may increase due to liver damage following overdose. Plasma protein binding of acetaminophen is about 10 to 25%. Antipyretic effects occur via inhibition of the hypothalamic heat-regulating center. Acetaminophen is readily absorbed from the gastrointestinal tract. The hypothesis has been that it results from COX inhibition and activation of descending serotonergic inhibitory pathways in the CNS. Īcetaminophen's mechanism of action of analgesia is not fully understood.

Hydrocodone has to be metabolized by CYP2D6 to its active form, hydromorphone. Hydrocodone reaches maximum serum concentrations within 1 hour with an elimination half-life of 4 to 6 hours. Additionally, activated opioid receptors inhibit neurotransmitter release, including substance P. Activated mu-opioid receptors lead to inhibition of nociceptive pain reflexes and induce profound analgesia without affecting other sensory modalities such as touch.

Hydrocodone is a full opioid agonist that interacts with the mu-receptors and, to a lesser extent, with delta receptors in the body.
