	Opioids : past, present and future
		Yet the therapeutic implications of a recognition that dysfunctional endogenous opioid systems underlie a spectrum of anxiety-disorders and depression are too radical - at present - for the medical establishment to contemplate.
		Opioid users are frequently forced into crime to pay for pharmacotherapies that should be cheaply and safely available; and damned for seeking a state of mind which will one day be their birthright: invincible happiness.
		For one of our three major endogenous opioid families is implicated in profoundly dysphoric psychological effects: a cruel negative-feedback system exists between the mu and kappa systems that "corrects" any "excess" tendency to well-being.

	Opioid - Wikipedia, the free encyclopedia
		There are four broad classes of opioids: endogenous opioid peptides, produced in the body; opium alkaloids, such as morphine (the prototypical opioid) and codeine; semi-synthetic opioids such as heroin and oxycodone; and fully synthetic opioids such as pethidine and methadone that have structures unrelated to the opium alkaloids.
		Opioids are widely used in medicine as strong analgesics (pain relievers).
		Opioids decrease the proliferation of macrophage progenitor cells and lymphocytes, and affect cell differentiation.

	Opioid Receptors
		-receptor was subsequently proposed to explain the profile of activity in vitro of the enkephalins (the first endogenous opioid peptides), and on the basis of the relative potency of the non-selective opioid antagonist naloxone to reverse endogenous opioid peptide inhibition of the nerve-evoked contractions of the mouse vas deferens.
		The opioid receptor family, in common with the somatostatin receptor family, is somewhat unusual in that all of the cloned opioid receptor types belong to the G
		With the benefit of hindsight, it is possible to conceive an evolution of those opioid analogues, with a progressive simplification of chemical structure from the epoxymorphinans (nalorphine, nalbuphine) through the morphinans such as levorphanol, and the benzomorphans such as pentazocine, to the phenyl-piperidines including pethidine and the 4-anilino-piperidines as exemplified by fentanyl (Figure 1).

	Patent RE38,407
		The amount of the opioid analgesic agent or drug to be included in the liposomal preparation is not, per se, critical and can vary within wide limits depending inter alia on the particular agent, the intended application and the lipid used.
		Suitable active ingredients are opioid analgesic agents including such opioid agents as alfentanil, anileridine, codiene, diamorphine, fentanyl, hydrocodone, hydromorphone, meperidine (pethidine), morphine, oxycodone, oxymorphone, propoxyphene and sufentanil and the opioid agonists and antagonists pentazocine and nalbuphine.
		The liposome-encapsulated opioid analgesic agents normally are administered to a human patient in an amount to provide an accepted and necessary level of therapeutic postoperative analgesic plasma concentration, commonly agreed to be in the range of 0.2 to 1.2 ng/ml.

	Book Excerpt: Principles of Pharmacology for Athletic Trainers
		Opioid analgesics are drugs that have pharmacological activity similar to morphine, which is the prototype for this drug category.
		Opioid analgesics affect the cough center in the medulla to cause cough suppression.
		Opioid analgesics are often combined with acetaminophen, or sometimes with aspirin or ibuprofen, because the combination of an opioid and nonopioid analgesic provides a synergistic effect, which enhances the analgesia without adding to the adverse effects of either drug.

	OXYCONTIN Label
		Oxycodone is an opioid agonist of the morphine-type.
		Opioid analgesics have a narrow therapeutic index in certain patient populations, especially when combined with CNS depressant drugs, and should be reserved for cases where the benefits of opioid analgesia outweigh the known risks of respiratory depression, altered mental state, and postural hypotension.
		Opioid antagonists should not be administered in the absence of clinically significant respiratory or circulatory depression secondary to oxycodone overdose.

		Analgesic and respiratory depressant effects are similar to those elicited by morphine in normal clinical doses; however, a ceiling effect limits these responses in overdose.
		Opioid analgesics are problematic in patients with impaired respiration, as may accompany advanced emphysema or poorly controlled myasthenia gravis.
		Opioids -- generally combined with acetaminophen for prescribing convenience -- may also be used as a supplement to an NSAID for additional pain relief if needed (for example, if the analgesic effectiveness of the NSAID is shorter in duration than the dosing interval).

	Volume IX
		The higher opioid requirements of highly tolerant patients treated for pain increase the likelihood of unpleasant nonanalgesic side effects due to greater circulating concentrations of opioids and potentially toxic opioid metabolites.
		Morphine is metabolized to morphine-3-glucuronide (M3G), an analgesically inactive metabolite, and morphine-6-glucuronide (M6G), a potent analgesic.
		Thus, it is plausible that clinical analgesic tolerance to morphine may, at least in part, result from an increasing accumulation of M3G in plasma and cerebrospinal fluid relative to morphine and M6G.

		E. If an opioid is to be started in a patient who is not opioid-naive, the dose equianalgesic to the previous opioid should be estimated.
		Or, for patients on high opioid doses, calculate the 24 hour opioid dose, convert this dose to parenteral (morphine) and then divide by 24 to determine the hourly dose.
		Twycross states that tolerance to the analgesic effect is not a clinical problem when opioids are used in chronic pain in cancer patients.

	The Double Effect of Pain Medication
		Although a review of the medical literature reveals that the risk of respiratory depression from opioid analgesic is more myth than fact and that there is little evidence that the use of medication to control pain hastens death, the belief in the double effect of pain medication remains widespread.
		Furthermore, using the PDE to justify using opioids to treat pain in dying patients contributes to the belief in the double effect of pain medication, which in turn leads to fear of hastening death and the undertreatment of pain.
		It is ironic that an ethical principle that is used to justify adequate opioid analgesics contributes to the undertreatment of pain.

	Progress in Opiate Pharmacology
		Until recently, all clinically used opioid analgesics were considered pharmacologically equivalent to morphine with respect to both analgesic mechanisms and side effects, differing only in potency, duration of action, or oral availability.
		Opioid receptors have been classified by their selectivity in binding and pharmacological assays (Tables 1 and 2) and, more recently, through a series of selective antagonists (Table 3).

	opiod
		The selection of the appropriate analgesic therapy is based on the interplay of the intensity of each patient's pain and current analgesic therapy.
		If a patient has mild-to-moderate pain despite taking a nonopioid analgesic, the dose of the nonopioid analgesic should be maximized and a step 2 opioid analgesic (a "mild" opioid such as codeine, hydrocodone or oxycodone) should be added.
		Patients who have moderate-to-severe pain despite therapy with step 2 opioids require an increase in the dose of the opioid or, if that is not feasible, a change to a step 3 opioid (a "major" opioid such as morphine, hydromorphone or fentanyl).

	Wisconsin physicians' knowledge and attitudes about opioid analgesic regulations
		There were 17 factual questions about regulations including multiple choice questions about opioid schedule and number of refills; true/false questions of the ability to prescribe an emergency supply of Schedule II drugs by telephone and the ability of the Drug Enforcement Administration (DEA) to have a physician's license revoked.
		For analysis of opioid prescribing practice the data was collapsed into two groups; physicians prescribing five or fewer prescriptions per month, and those who prescribe six or more.
		Despite the lack of significant regulatory impediments to opioid prescribing in Wisconsin, the results of this survey suggest that Wisconsin physicians are concerned about regulatory scrutiny and that they have poor knowledge of controlled substance regulations.
