    Pain - General

    • Pain is an unpleasant sensory and emotional experience associated with or resembling tissue damage.
    • It can be neuropathic, nociceptive, or nociplastic and can be acute or chronic, primary or secondary in nature.
    • Chronic pain is defined as pain that has been present for more than 12 weeks beyond the expected time of wound healing.
    • It is a complex phenomenon that can have a considerable impact on quality of life, resulting in significant suffering and disability.
    • Chronic primary pain is defined as pain that has no clear underlying condition or where the pain appears out of proportion to any observable injury or disease.
    • Types of chronic primary pain include complex regional pain syndrome, fibromyalgia, primary headache and orofacial pain, primary visceral, and primary musculoskeletal pain.
    • Secondary pain is caused by an underlying condition and can be organized into six pain categories: cancer-related, neuropathic, post-surgical or post-traumatic, secondary headache or orofacial, secondary musculoskeletal, and secondary visceral.
    • Depression is a common comorbidity in those with chronic pain, and individuals should be monitored and treated for depression as appropriate.
    • Treatment aims to reduce pain and the impact of chronic pain on quality of life, mood, and function.
    • A wide range of both pharmacological and nonpharmacological management strategies are available for chronic pain, with treatment options guided by any known underlying chronic pain condition(s).

    Pain - Treatment

    • Non-drug treatment includes exercise and exercise therapies, with strategies to improve adherence.
    • Transcutaneous electrical nerve stimulation (TENS) may be considered for relief of chronic pain.
    • Referral to a pain management program and psychologically-based interventions such as cognitive behavioral therapy, biofeedback, and progressive relaxation should be considered for patients with chronic pain.
    • Brief education should be given to all patients.
    • Self-management resources should be considered to complement other therapies in the treatment of chronic pain.
    • Chronic pain treatment involves the use of various analgesics, including non-opioid, opioid, and adjuvant analgesics.
    • The WHO analgesic ladder is widely used to guide the basic treatment of acute and chronic pain, although there is little evidence to support its use in chronic pain.
    • Individual responses to analgesia vary considerably, both in terms of efficacy and side-effects.
    • Even with the same chronic pain syndrome, the underlying pain mechanisms may differ between individuals, providing challenges with assessment and management in routine clinical practice.

    Pain - Non-opioid Analgesics

    • Non-opioid analgesics include paracetamol and NSAIDs (in both oral and topical forms).
    • Single-ingredient analgesics are preferred for independent titration, but fixed-dose combination analgesics may be considered for those with stable chronic pain.

    Pain - Opioid Analgesics

    • Opioid analgesics can be divided into those used for mild-to-moderate pain (such as codeine phosphate) and those used for moderate-to-severe pain (such as morphine or oxycodone hydrochloride).
    • Opioids should only be considered in carefully selected individuals for short- to medium-term treatment of chronic non-malignant pain when other therapies have been insufficient.
    • The benefits should outweigh the risks of serious harms (such as addiction, overdose, and death).
    • Prescribers should have knowledge of opioid pharmacology and be competent and experienced in the use of strong opioids.
    • When starting treatment with an opioid, there should be an agreement between the prescriber and patient about the expected outcomes, with advanced agreement on reduction and cessation if these are not met.
    • Opioids should be reviewed at least annually but more frequently if required, considering a gradual reduction to the lowest effective dose or complete cessation.
    • Pain specialist advice or review should be sought for individuals taking doses >90 mg/day morphine equivalent.

    Pain - Adjuvant Analgesics

    • Adjuvant analgesics, such as antidepressants, antiepileptics, benzodiazepines, bone-modulating drugs, corticosteroids, and topical capsaicin, lidocaine, and rubefacients, are used to manage chronic primary pain.
    • Non-opioid drugs like paracetamol and aspirin are suitable for pain in musculoskeletal conditions, while opioid analgesics are more suitable for moderate to severe pain, particularly of visceral origin.

    Pain - MHRA/CHM Information on Opioids

    • The MHRA/CHM have issued important safety information on the use of opioids and the risk of dependence and addiction.

    Pain - Sickle-Cell Disease

    • Pain in sickle-cell disease is managed with paracetamol, a NSAID, codeine phosphate, or dihydrocodeine tartrate.
    • Severe crises may require morphine or diamorphine hydrochloride.
    • Pethidine hydrochloride should be avoided if possible due to its neurotoxic metabolite accumulation and short half-life.

    Pain - Dental Care

    • Analgesics should be used judiciously in dental care as a temporary measure until the cause of the pain has been dealt with.
    • Most dental pain is effectively relieved by non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, diclofenac sodium, and aspirin.
    • Paracetamol has analgesic and antipyretic effects but no anti-inflammatory effect.
    • Opioid analgesics, such as dihydrocodeine tartrate, act on the central nervous system and are traditionally used for moderate to severe pain.
    • Opioid analgesics are relatively ineffective in dental pain and their side-effects can be unpleasant.
    • Combining a non-opioid with an opioid analgesic can provide greater relief of pain than either analgesic given alone, but this applies only when an adequate dose of each analgesic is used.
    • Most combination analgesic preparations have not been shown to provide greater relief of pain than an adequate dose of the non-opioid component given alone, and they have the disadvantage of an increased number of side-effects.
    • Analgesics given before dental procedures should have a low risk of increasing postoperative bleeding.
    • In the case of pain after the dental procedure, taking an analgesic before the local anesthetic has worn off can improve control.
    • Postoperative analgesia with ibuprofen or aspirin is usually continued for about 24 to 72 hours.

    Pain - Temporomandibular Dysfunction

    • Temporomandibular dysfunction can be related to anxiety in some patients who may clench or grind their teeth (bruxism) during the day or night.
    • The muscle spasm may be treated empirically with an overlay appliance which provides a free sliding occlusion and may also interfere with grinding.
    • Diazepam, which has muscle relaxant and anxiolytic properties, may be helpful but should only be prescribed on a short-term basis during the acute phase.
    • Analgesics such as aspirin or ibuprofen may also be required.

    Pain - Dysmenorrhoea

    • Dysmenorrhoea is generally associated with ovulatory cycles and can be prevented with the use of an oral contraceptive.
    • Paracetamol or NSAIDs provide adequate relief of pain, but antiemetics may be needed for vomiting and severe pain associated with dysmenorrhoea in women with endometriosis.

    Pain - Non-Opioid Analgesics - Further information

    • Non-opioid analgesics and compound analgesic preparations are used for headache, transient musculoskeletal pain, dysmenorrhoea, and pyrexia.
    • Aspirin is indicated for headache, transient musculoskeletal pain, dysmenorrhoea, and pyrexia.
    • Paracetamol is similar in efficacy to aspirin but has no demonstrable anti-inflammatory activity; it is less irritant to the stomach and is now generally preferred to aspirin, particularly in the elderly.
    • Nefopam hydrochloride may have a place in the relief of persistent pain unresponsive to other non-opioid analgesics but may cause synapthomimetic and antimuscarinic side-effects.

    Pain - Non-Steroidal Anti-Inflammatory Analgesics (NSAIDs)

    • Non-steroidal anti-inflammatory analgesics (NSAIDs) are particularly useful for the treatment of patients with chronic disease accompanied by pain and inflammation.
    • Some are also used in the short-term treatment of mild to moderate pain including transient musculoskeletal pain, but paracetamol is now often preferred, particularly in the elderly.
    • Selective inhibitors of cyclo-oxygenase-2 may be used in preference to non-selective NSAIDs for patients at high risk of developing serious gastro-intestinal side-effects.
    • Several NSAIDs are also used for postoperative analgesia.

    Pain - Compound Analgesic Preparations

    • Compound analgesic preparations that contain a simple analgesic with an opioid component reduce the scope for effective titration in the management of pain of varying intensity.
    • A full dose of the opioid component in compound analgesic preparations effectively augments the analgesic activity but is associated with the full range of opioid side-effects.
    • It is important to weigh up whether there is a need for a non-opioid and an opioid analgesic to be taken simultaneously when assessing pain.

    Pain - Opioid Analgesics - Further Treatment

    • Opioid analgesics are used to relieve moderate to severe pain, particularly of visceral origin. They can cause dependence and tolerance, but they are not deterrents in the control of pain in terminal illness.
    • Regular use of a potent opioid may be appropriate for certain cases of chronic non-malignant pain.
    • Morphine is the most valuable opioid analgesic for severe pain, although it frequently causes nausea and vomiting. It is the standard against which other opioid analgesics are compared.
    • Morphine is the opioid of choice for the oral treatment of severe pain in palliative care and is given regularly every 4 hours or every 12 or 24 hours as modified-release preparations.
    • Buprenorphine has both opioid agonist and antagonist properties and may precipitate withdrawal symptoms, including pain, in patients dependent on other opioids.
    • It has abuse potential and may itself cause dependence. It has a much longer duration of action than morphine and is effective sublingually for 6 to 8 hours. Unlike most opioid analgesics, the effects of buprenorphine are only partially reversed by naloxone hydrochloride.
    • Dipipanone hydrochloride is less sedating than morphine but the only preparation available contains an antiemetic, making it not suitable for regular regimens in palliative care.
    • Diamorphine hydrochloride (heroin) is a powerful opioid analgesic that may cause less nausea and hypotension than morphine.
    • Alfentanil, fentanyl, and remifentanil are used by injection for intra-operative analgesia.
    • Methadone hydrochloride is less sedating than morphine and acts for longer periods, but should not be administered more than twice daily to avoid accumulation and opioid overdosage.
    • Oxycodone hydrochloride is commonly used as a second-line drug if morphine is not tolerated or does not control the pain.
    • Codeine phosphate is a weak opioid used for mild to moderate pain relief, similar to dihydrocodeine tartrate. Higher doses may provide additional pain relief but may result in more nausea and vomiting.
    • Meptazinol has a low incidence of respiratory depression and a reported length of action of 2 to 7 hours.

    Pain - Postoperative Analgesia

    • Postoperative analgesia can be managed using a multimodal approach using a combination of analgesics from different classes.
    • Intra-operative opioids affect the prescribing of postoperative analgesics, and a postoperative opioid analgesic should be given with care as it may potentiate residual respiratory depression.
    • Morphine is the most widely used opioid, while Tramadol hydrochloride is less effective in severe pain.
    • Buprenorphine may antagonize the analgesic effect of previously administered opioids and is generally not recommended.
    • Pethidine hydrochloride is generally not recommended for postoperative pain due to its metabolization to norpethidine, which may accumulate in renal impairment and stimulate the central nervous system.
    • Opioids are also given epidurally in the postoperative period but are associated with side-effects such as pruritus, urinary retention, nausea, and vomiting.
    • Patient-controlled analgesia (PCA) can be used to relieve postoperative pain.

    Pain - Penthrox®

    • The manufacturer of Penthrox®, a non-opioid medication, advises that it should only be self-administered under the supervision of personnel experienced in its use, using a hand-held Penthrox® inhaler device.
    • It has been indicated for moderate-to-severe pain associated with trauma and is recommended for adults to administer 3-6 mL as required, avoid administration on consecutive days, and administer using an inhaler device.
    • The contra-indications include cardiovascular disease, liver damage, impaired consciousness, respiratory depression, susceptibility to malignant hyperthermia, and contraindications for elderly individuals, repeated administration more than once every three months, increased risk of hepatic injury, and risk factors for renal impairment. ### Methoxyflurane

    Opioids

    • MHRA has issued a warning about the potential risks associated with co-prescription of opioids with benzodiazepines and benzodiazepine-like drugs.
    • Co-prescription of opioids with benzodiazepines and benzodiazepine-like drugs can lead to additive CNS depressant effects, increasing the risk of sedation, respiratory depression, coma, and death.
    • Healthcare professionals should only co-prescribe if there is no alternative and to administer the lowest possible doses for the shortest duration.
    • Patients should be closely monitored for signs of respiratory depression at treatment initiation and when there is any change in prescribing, such as dose adjustments or new interactions.
    • If methadone is coprescribed with a benzodiazepine or benzodiazepine-like drug, the respiratory depressant effect of methadone may be delayed, and patients should be monitored for at least two weeks after initiation or changes in prescribing.
    • Patients should be informed of the signs and symptoms of respiratory depression and sedation and advised to seek urgent medical attention if these occur.
    • New safety recommendations have been issued following a review of the risks of dependence and addiction associated with prolonged use of opioids for non-malignant pain.
    • Healthcare professionals are advised to discuss with patients that prolonged use of opioids, even at therapeutic doses, may lead to dependence and addiction.
    • Healthcare professionals should agree a treatment strategy and plan for the end of treatment with the patient before starting opioids.
    • Patients and their carers should be counseled on the risks of tolerance and potentially fatal unintentional overdose, as well as signs and symptoms of overdose.
    • Healthcare professionals should provide regular monitoring and support to patients at increased risk, such as those with current or history of substance use disorder (including alcohol misuse) or mental health disorders.
    • Opioid dosage should be gradually tapered at the end of treatment.
    • Consider hyperalgesia in patients on long-term opioid treatment who present with increased pain sensitivity.
    • Contra-indications include acute respiratory depression, comatose patients, head injury, raised intracranial pressure, and risk of paralytic ileus.
    • Cautions include adrenocortical insufficiency, asthma, central sleep apnoea, convulsive disorders, current or history of mental health disorder, current or history of substance use disorder, debilitated patients, diseases of the biliary tract, elderly, hypotension, hypothyroidism, impaired respiratory function, inflammatory bowel disorders, myasthenia gravis, obstructive bowel disorders, prostatic hypertrophy, shock, urethral stenosis.
    • Opioids cause a dose-dependent increased risk of central sleep apnea, so total opioid dose reduction is recommended.
    • Palliative care should not necessarily be a deterrent to the use of opioid analgesics in terminal illness.
    • Elderly prescriptions may be potentially inappropriate, especially if prescribed a strong, oral or transdermal opioid (morphine, oxycodone, fentanyl, buprenorphine, diamorphine, methadone, tramadol, pethidine, and pentazocine) as first-line therapy for formild pain.
    • Overdose opioids can cause coma, respiratory depression, and pinpoint pupils.
    • In pregnancy, respiratory depression and withdrawal symptoms can occur in the neonate if opioid analgesics are used during delivery.
    • Treatment should avoid abrupt withdrawal after long-term treatment and be withdrawn gradually to avoid abstinence symptoms.
    • The Faculty of Pain Medicine has created resources for healthcare professionals regarding opioid prescribing.
    • Drowsiness may affect the performance of skilled tasks, and the effects of alcohol are enhanced.
    • Driving at the start of therapy with opioid analgesics and following dose changes should be avoided.
