Oxycodone can also inhibit hormone release of somatostatin, insulin, vasopressin, and glucagon. Oxycodone is a weak agonist of μ – mu, κ – kappa, and δ – delta opioid receptors within the CNS. As κ -receptor agonist oxycodone closes N-type voltage-operated calcium channels, while as μ and δ receptor agonist, oxycodone opens calcium-dependent potassium channels. Oxycodone decrease intracellular levels of cAMP by inhibiting enzyme called adenylate cyclase and release of nociceptive neurotransmitters such as GABA, dopamine, substance P, acetylcholine, and noradrenaline. The results are hyperpolarization and reduced neuronal excitability. Oxycodone predominantly affects μ opioid receptors, which are binded with G-protein receptors complex and acts as modulators, both negative and positive, of synaptic transmission through G-proteins that trigger effector proteins.
Hydrocodone is predominantly prescribed in the US. According to the the International Narcotics Control Board, 99% of the worldwide hydrocodone supply in 2007 was consumed in the US.
Hydrocodone decreases synaptic chemical transmission in the CNS, which in turn inhibits pain sensation into the higher centers of the brain. Agonist activities at the μ and kappa receptors can cause analgesia, miosis, and decreased body temperature. Instead, they alter the perception of pain at the spinal cord and higher concentrations in the CNS and the person’s emotional response to pain. This morphinans structure substance blocks pain perception in the cerebral cortex of the brain. Opiate agonists don’t change the threshold or responsiveness of afferent nerve endings to noxious stimuli nor the conduction of impulses along peripheral nerves. Hydrocodone acts at several locations within the CNS by involving several systems of neurotransmitters to produce analgesia, but the precise mechanism of action has not been fully understood. Hydrocodone is an opioid agonist of opioid receptors within the CNS. Agonist activity at the μ receptor can also cause the suppression of opiate withdrawal, while antagonist activity can result in precipitation of withdrawal. Hydrocodone can produce inhibition at the chemoreceptors through μ-opioid receptors and in the medulla through μ and δ receptors which can lead to dose-related respiratory depression.
Patients could also experience higher level of drowsiness, dizziness, nausea and sedation. The best option for patient is to stick with one medicine and adjust the dose to achieve pain relief as directed by physician. These drugs belong to the same pharmacological class and have very similar effects in the body. Taking them together patients may increase the risk of side effects to happen. Patients should never take hydrocodone and oxycodone together at the same time. The most serious side effect that can happen during administration of these drugs combination is slowing or stopping of breathing (respiratory depression) which could cause death.
Oxycodone is a Generic name for an opioid narcotic drug containing same name active ingredient that is used for moderate to severe pain relief. Oxycodone dose should be adjusted individually, according to the pain severity and the patient response. As a narcotic analgesic, oxycodone is more potent and addicting than its related compound codeine. The extended-release form of this drug is for around-the-clock therapy of pain. Oxycodone is available in the form of tablet (extended or immediate release), capsule and solution in following strengths: 5, 10, 15, 20, 30, 40 and 80 mg. The dose can be exceeded in patients who have more severe pain or in those who become tolerant to the opioids analgesic effects. This form of oxycodone is not for use on an as-needed basis for pain.

This drug is narcotic analgesic which is used orally for relieving the moderate to severe pain, but it is also commonly used in liquid form as an antitussive agent for symptomatic relief of nonproductive cough, alone or together with other cough suppressants or expectorants. However, hydrocodone is only used for the treatment of patients who are expected to need painkiller for severe pain for a long time, and who cannot be treated with other medicines or treatments. This drug works by changing the way the brain and nervous system respond to pain. Hydrocodone is a Generic name for an opioid drug which is synthesized from codeine, an opioid alkaloid that can be found in the opium poppy. As an analgesic, hydrocodone is usually combined with ibuprofen, acetaminophen or aspirin for pain treatment. The analgesic action of hydrocodone starts in 20–30 minutes and lasts for about 4–8 hours.
