1. what anorphinan is and what it is used for

Anorphinan is a prolonged-release tablet, which means that its active substances are released over an extended period. Their action lasts for 12 hours.

Pain relief

You have been prescribed Anorphinan for the treatment of severe pain, which can be adequately managed only with opioid analgesics. Naloxone is added to counteract constipation.

How Anorphinan works in pain relief

Anorphinan tablets contain oxycodone and naloxone as active substances. Oxycodone is responsible for the pain relieving effect of Anorphinan. It is a strong analgesic (“painkiller”) that belongs to a group of medicines called opioids. Naloxone is intended to counteract constipation. Constipation is a typical side effect of treatment with opioid painkillers.

2. what you need to know before you take anorphinan

Do not take Anorphinan tablets

• if you are allergic to oxycodone or naloxone or any of the other ingredients of this medicine (listed in section 6),
• if you have breathing problems, such as breathing more slowly or weakly than expected (respiratory depression),
• if you suffer from a severe lung disease associated with narrowing of the airways (chronic obstructive pulmonary disease or COPD),
• if you suffer from a condition known as cor pulmonale. In this condition the right side of the heart becomes enlarged, due to increased pressure inside blood vessels in the lung etc. (e.g. as a result of COPD – see above),
• if you suffer from severe bronchial asthma,
• if you have a type of bowel obstruction (paralytic ileus) not caused by opioids,
• if you have moderate to severe liver problems.

Warnings and Precautions

Talk to your doctor or pharmacist before taking Anorphinan:

• in the case of elderly or debilitated (weak) patients,
• if you have a type of bowel obstruction (paralytic ileus) caused by opioids,
• if you have kidney problems,
• if you have mild liver problems,
• if you have severe lung problems (i.e. reduced breathing capacity),
• if you suffer with a condition characterised by frequent breathing stops during the night, which may make you feel very sleepy during the daytime (sleep apnoea),
• if you have myxoedema (a thyroid disorder, with dryness, coldness and swelling [‘puffiness’] of the skin, affecting the face and limbs),
• if your thyroid gland is not producing enough hormones (underactive thyroid, or hypothyroidism),
• if your adrenal glands are not producing enough hormones (adrenal insufficiency, or Addison’s disease),
• if you have a mental illness accompanied by a (partial) loss of reality (psychosis), due to alcohol or intoxication with other substances (substance-induced psychosis),
• if you suffer from gallstone problems,
• if your prostate gland is abnormally enlarged (prostate hypertrophy),
• if you are or ever have been addicted to alcohol or drugs, or have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating upon stopping alcohol or drugs (delirium tremens),
• if your pancreas is inflamed (pancreatitis),
• if you have low blood pressure (hypotension),
• if you have high blood pressure (hypertension),
• if you have pre-existing heart disease,
• if you have a head injury (due to the risk of increased brain pressure),
• if you suffer from epilepsy or are prone to fits,
• if you are also taking a type of medicine known as a MAO inhibitor (used to treat depression or Parkinson’s di­sease), e.g. medicines containing tranylcypromine, phenelzine, isocarboxazid, moclobemide and linezolid.
• if sleepiness or episodes of suddenly falling asleep occur.

Tell your doctor if any of the above has ever applied to you in the past. Also, please tell your doctor if you develop any of the above disorders while you are taking Anorphinan.

The most dangerous consequence of opioid overdose is slow and shallow breathing (respiratory depression). This may also cause blood oxygen levels to fall, which might result in fainting, etc.

There is no clinical experience with Anorphinan in cancer patients with peritoneal metastases or the beginnings of bowel obstruction at the advanced stages of digestive tract and pelvic cancer. Anorphinan is therefore not recommended for use in these patients.

Children and adolescents

This medicine must not be given to children or adolescents under 18 years of age as the safety and benefits have not been shown yet.

How to use Anorphinan correctly

If you experience severe diarrhoea at the start of treatment (within the first 3–5 days) this may be due to the effect of naloxone. It may be a sign that your bowel movements are returning to normal. If diarrhoea persists after 3–5 days, or it gives you cause for concern, please contact your doctor.

If you have been using high doses of another opioid, withdrawal symptoms (such as restlessness, bouts of sweating or muscle pain) may occur when you initially switch to taking these tablets. If you experience withdrawal symptoms, you may need to be specially monitored by your doctor.

If you need to undergo surgery, please tell your doctor that you are taking this medicine.

If you have been taking this medicine for a long time, you may become tolerant. This means you may need a higher dose to achieve the desired effect. Long-term use of these tablets may also lead to physical dependence. Withdrawal symptoms may occur if treatment is stopped too suddenly. If you no longer need treatment, you should reduce your daily dose gradually, in consultation with your doctor.

As with other strong opioid painkillers, there is a risk that you may develop a psychological dependence to oxycodone. Medicines containing oxycodone should be avoided in patients with a present or past abuse of alcohol, drugs or medicines.

You may notice remains of the tablet in your stools. Do not be alarmed, as the active substances will have already been released in the stomach and gut, and absorbed into your body.

Incorrect use of Anorphinan

Anorphinan is not suitable for withdrawal treatment.

This medicine should never be abused, particularly if you have a drug addiction. If you are addicted to drugs such as heroin, morphine or methadone, severe withdrawal symptoms are likely if you abuse this medicine because it contains the ingredient naloxone. Preexisting withdrawal symptoms may be made worse.

You should never misuse the tablets by dissolving and injecting them (e.g. into a blood vessel). They contain talc, which can cause destruction of local tissue (necrosis) and changes in lung tissue (lung granuloma). Misuse can also have other serious consequences which may be fatal.

The use of Anorphinan may lead to positive results in doping controls. The use of Anorphinan as a doping agent may endanger health.

Other medicines and Anorphinan

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

The risk of side effects is increased if you take these tablets at the same time as medicines which affect the way the brain works. For example, you may feel very sleepy, or breathing problems (slow and shallow breathing) may get worse.

• Examples of medicines that affect the way the brain works include: other strong painkillers (opioids),
• sleep medication and tranquilisers (sedatives, hypnotics),
• antidepressants,
• medicines used to treat allergies, travel sickness or nausea (antihistamines or antiemetics),
• other medicines which act on the nervous system (phenothiazines, neuroleptics).

Concomitant use of Anorphinan and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However if your doctor does prescribe Anorphinan together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor. Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms’.

Tell your doctor if you are taking:

• medicines that decrease the blood’s clotting ability (coumarin derivatives), this clotting time may be speeded up or slowed down
• antibiotics of the macrolide type (such as clarithromycin)
• antifungal medicines of the -azole type (e.g. ketoconazole)
• ritonavir or other protease inhibitors (used to treat HIV)
• rifampicin (used to treat tuberculosis)
• carbamazepine (used to treat seizures, fits or convulsions and certain pain conditions)
• phenytoin (used to treat seizures, fits or convulsions).

The risk of side effects increases, if you use antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medicines may interact with oxycodone and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. Contact your doctor when experiencing such symptoms.

Anorphinan with food, drink and alcohol

Drinking alcohol whilst taking Anorphinan may make you feel more sleepy or increase the risk of serious side effects such as shallow breathing with a risk of stopping breathing, and loss of consciousness. It is recommended not to drink alcohol while you are taking Anorphinan.

You should avoid drinking grapefruit juice while you are taking this medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Use of Anorphinan during pregnancy should be avoided unless your doctor finds treatment with this medicine is essential. If used over prolonged periods during pregnancy, oxycodone may lead to withdrawal symptoms in the newborn baby. If oxycodone is given during childbirth, the baby may have breathing problems such as slow and shallow breathing (respiratory depression).

Breastfeeding

Breastfeeding should be stopped during treatment with this medicine as oxycodone (one of the active substances of this medicine) passes into breast milk and it is not known whether naloxone also passes into breast milk. Therefore, a risk for the breastfed infant cannot be excluded in particular following intake of multiple doses of this medicine.

Driving and using machines

This medicine can affect your ability to drive or operate machines as it may make you sleepy or dizzy. This is most likely at the start of your treatment, after a dose increase or after switching from a different medication. These side effects should disappear once you are on a stable dose.

This medicine has been associated with sleepiness and episodes of suddenly falling asleep. If you experience these side effects, you must not drive or operate machinery. You should tell your doctor if this occurs.

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

Anorphinan contains lactose

Anorphinan 5 mg/2.5 mg and 10 mg/5 mg contain lactose (milk sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking Anorphinan 5 mg/2.5 mg and 10 mg/5 mg.

3. how to take anorphinan

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

You must swallow the prolonged-release tablet whole, so as not to affect the slow release of oxycodone from the tablet. Do not break, chew or crush the prolonged-release tablets. Taking broken, chewed or crushed tablets may result in your body absorbing a potentially fatal dose of oxycodone (see under “If you take more Anorphinan than you should”).

Unless otherwise prescribed by your doctor, the usual dose is:

To treat pain

Adults

The usual starting dose is one Anorphinan 10 mg/5 mg prolonged-release tablet every 12 hours.

Your doctor will decide how much you should to take every day and how to divide the total daily dose into morning and evening doses. The doctor will also decide on any necessary dose adjustment during treatment depending on your level of pain and individual sensitivity. You should be given the lowest dose needed for pain relief. If you have already been treated with opioids, your treatment with this medicine may be started at a higher dose.

The maximum daily dose is 160 mg oxycodone hydrochloride and 80 mg naloxone hydrochloride. If you need a higher dose, your doctor may give you additional oxycodone without naloxone. However, the maximum daily dose of oxycodone should not exceed 400 mg. The beneficial effect of naloxone on bowel movements may be affected if additional oxycodone is given without additional naloxone.

If you experience pain between doses of Anorphinan, you may need to take an additional fast-acting painkiller. Anorphinan is not suitable for this. Please talk to your doctor.

If you feel that these tablets are too strong or too weak, please talk to your doctor or pharmacist.

Elderly patients

In general, no dose adjustment is necessary for elderly patients with normal kidney and/or liver function.

Liver or kidney problems

If you have kidney or mild liver problems your doctor will prescribe Anorphinan with special caution. You must not take these tablets if you have moderate or severe liver problems (see also Section 2 “Do not take Anorphinan tablets” and “Warnings and Precautions”).

Children and adolescents below 18 years of age

No studies have been carried out to show that this medicine work properly in children and adolescents, or are safe for them to take. It is therefore not recommended for use in patients under 18 years of age.

Method of administration

Swallow your tablets whole with a glass of water. You can take these tablets with or without food. Take them every 12 hours, according to a fixed time schedule. For instance, if you take a tablet at 8 o’clock in the morning, you should take your next tablet at 8 o’clock in the evening. Do not break, chew or crush the tablets.

If you forget to take Anorphinan,

If you forget to take Anorphinan or if you take a lower dose than the one prescribed, you may not feel any effect.

If you should forget to take your dose, please follow the instructions below:

• If your next usual dose is due in 8 hours or more: Take the forgotten dose immediately and continue with your normal dosing schedule.
• If your next usual dose is due in less than 8 hours: Take the forgotten dose, then, wait another 8 hours before taking your next dose. Try to get back in your normal dosing schedule (e.g. 8 o’clock in the morning and 8 o’clock in the evening).

Do not take more than one dose within any 8-hour period.

Do not take a double dose to make up for a forgotten dose.

If you stop taking Anorphinan

Do not stop taking your treatment without first consulting your doctor.

If you do not require any further treatment, your doctor will advise you how to reduce the daily dose gradually. In this way, you will avoid withdrawal symptoms, such as restlessness, bouts of sweating and muscle pain.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
