Omnopon 1.44+11.5+5.4+0.72+0.1 mg/ml solution subcutaneous injection 1 ml amp No. 5


Omnopon

Omnopon increases the threshold of pain sensitivity, inhibits conditioned reflexes, causes euphoria and has a moderate hypnotic and central antitussive effect, increases the tone of the vagus nerve center, stimulates the vomiting center, depresses the respiratory center, causes constriction of the pupil due to activation of the oculomotor nerve center, weakens intestinal motility, inhibits secretory activity of the glands of the gastrointestinal tract. Somewhat reduces basal metabolism and body temperature, stimulates the release of antidiuretic hormone. When Omnopon is administered subcutaneously, the analgesic effect develops within 10-15 minutes and lasts for 3-5 hours. The main pharmacological properties of Omnopon are due to the morphine it contains. Morphine is an agonist of predominantly mu-opioid receptors, activates the endogenous antinociceptive system and thus disrupts the interneuronal transmission of pain impulses at various levels of the central nervous system, and also changes the emotional coloring of pain, affecting the higher parts of the brain.

Morphine increases the threshold of pain sensitivity to stimuli of various modalities, inhibits conditioned reflexes, has a euphoric and moderate hypnotic effect, and increases the tone of the vagus nerve center. It can stimulate the chemoreceptors of the trigger zone of the vomiting center and cause nausea and vomiting, depresses the respiratory and vomiting centers, causes constriction of the pupil due to activation of the oculomotor nerve center, increases the tone of the bronchi and smooth muscle sphincters of internal organs (intestines, biliary tract, bladder), enhances contractile activity myometrium, weakens intestinal motility, inhibits the secretory activity of the glands of the gastrointestinal tract. Somewhat reduces basal metabolism and body temperature, stimulates the release of antidiuretic hormone. Causes dilation of peripheral blood vessels and the release of histamine, which can lead to a decrease in blood pressure, redness of the skin, increased sweating, and redness of the white of the eyes. Strengthens the effect on the central nervous system of drugs for general anesthesia, hypnotics, sedatives, H1 histamine receptor blockers with a central component of action, anxiolytic, antipsychotic and antidepressant drugs.

Papaverine is an antispasmodic agent that has a hypotensive effect, reduces tone and relaxes the smooth muscles of internal organs and blood vessels. Due to the content of papaverine, Omnopon causes spasms of the smooth muscles of internal organs to a lesser extent than morphine.

Codeine is a natural narcotic analgesic from the group of opioid receptor agonists. Analgesic activity is due to stimulation of opioid receptors in various parts of the central nervous system and peripheral tissues, leading to stimulation of the antinociceptive system and a change in the emotional perception of pain.

Thebaine is the smallest component of the drug. Thebaine's chemical structure is similar to morphine and codeine. Thebaine has an analgesic effect by acting on opioid receptors in the central nervous system. In its pharmacological properties, thebaine differs from morphine and codeine in that it produces an stimulating rather than a depressant effect on the nervous system. Thebaine in small doses has a weak hypnotic effect. Potentiates the effect of codeine and morphine.

Noscapine is a poppy hypnotic alkaloid, a derivative of benzylisoquinoline; is an agonist predominantly of σ-opioid receptors, has practically no analgesic properties, and has an antitussive effect. Noscapine has an antispasmodic effect on smooth muscles. It has a potentiating effect on the antispasmodic activity of papaverine.

PHARMACOLOGICAL PROPERTIES Omnopon - Refers to list II of the List of narcotic drugs, psychotropic substances and their precursors subject to control in the Russian Federation. The main pharmacological properties of omnopon are due to the morphine it contains. Morphine is an agonist of predominantly mu-opioid receptors, activates the endogenous antinociceptive system and thus disrupts the interneuronal transmission of pain impulses at various levels of the central nervous system, and also changes the emotional coloring of pain, affecting the higher parts of the brain.

Pharmacodynamics Omnopon increases the threshold of pain sensitivity, inhibits conditioned reflexes, causes euphoria and has a moderate hypnotic and central antitussive effect, increases the tone of the vagus nerve center, stimulates the vomiting center, depresses the respiratory center, causes constriction of the pupil due to activation of the oculomotor nerve center, weakens intestinal motility, inhibits the secretory activity of the glands of the gastrointestinal tract. Slightly reduces basal metabolism and body temperature. Stimulates the release of antidiuretic hormone. When omnopon is administered subcutaneously, the analgesic effect develops within 10-15 minutes and lasts for 3-5 hours. Papaverine hydrochloride is an antispasmodic agent that has a hypotensive effect, reduces tone and relaxes the smooth muscles of internal organs and blood vessels. Due to the content of papaverine, omnopon causes spasms of the smooth muscles of internal organs to a lesser extent than morphine. Codeine is a natural narcotic analgesic from the group of opiate receptor agonists. Analgesic activity is due to stimulation of opiate receptors in various parts of the central nervous system and peripheral tissues, leading to stimulation of the antinociceptive system and a change in the emotional perception of pain. Narcotine is an opioid alkaloid that suppresses the cough center.

Pharmacokinetics The volume of distribution of morphine is 4 l/kg. 30-35% of the drug is bound to plasma proteins. Morphine is excreted from the body in the form of glucuronide metabolites (up to 80%) or unchanged, mainly through the kidneys; a small part is excreted in bile and excreted in feces. The drug crosses the placental barrier and is found in breast milk. Papaverine undergoes biotransformation in the liver. It is excreted by the kidneys mainly in the form of metabolites. In plasma it binds to proteins. Codeine undergoes biotransformation in the liver, with 10% becoming mofin by demethylation. Excreted by the kidneys 5-15% in the form of codeine and 10% in the form of morphine and its metabolites. Communication with plasma proteins is insignificant.

Indications for use Severe pain syndrome of various origins, both acute and chronic (myocardial infarction, trauma, post-traumatic period, malignant neoplasms, in preparation for surgery and in the postoperative period, etc.). Pain syndrome (renal, hepatic, intestinal colic in combination with myotropic antispasmodics or atropine-like drugs).

Contraindications Hypersensitivity to the components of the drug. Conditions accompanied by respiratory depression or severe depression of the central nervous system. Convulsive states. Increased intracranial pressure. Head injury. Bronchial asthma. Paralytic ileus. Heart failure due to chronic lung diseases. Cardiac arrhythmias. Acute surgical diseases of the abdominal organs before diagnosis. Conditions after surgical interventions on the biliary tract. Co-administration with monoamine oxidase inhibitors and for 14 days after their discontinuation. Children under 2 years old. During pregnancy, childbirth and during breastfeeding, the use of Omnopon is permissible only for health reasons (the development of drug dependence in the fetus and newborn is possible). With caution - elderly patients, with general exhaustion, with liver and kidney disease, insufficiency of the adrenal cortex, patients with a history of indicating dependence on opioids.

Method of administration and dosage Doses of the drug are selected individually depending on the severity of the pain syndrome, age and condition of the patient. Typically, adults are administered subcutaneously 1 ml of a 1% or 2% solution. If necessary, the drug is re-administered after 4-5 hours. The highest single dose is 30 mg (3 ml of 1% solution or 1.5 ml of 2% solution), the highest daily dose is 100 mg (10 ml of 1% solution or 5 ml of 2% solution). For children over 2 years of age, the drug is prescribed in a dose of 1 mg (age 2-3 years) to 7.5 mg (age 12-14 years), taking into account the general condition and the required degree of pain relief.

Side effects Euphoria, urinary disorders, allergic reactions, depression, hallucinations, nausea, less commonly vomiting, dizziness, muscle weakness, constipation. Drowsiness or agitation, exacerbation of brain diseases due to increased intracranial pressure, spasms of the biliary tract and bladder sphincter, and moderate respiratory depression are also possible. To reduce side effects on the intestines, laxatives should be prescribed. Strengthens the inhibitory effect on the central nervous system of anesthesia, sleeping pills, sedatives, antihistamines with a central component of action, antidepressants, anxiolytic and antipsychotic drugs. Causes addiction and drug (opioid) dependence (physical and mental). Causes dilation of peripheral blood vessels and release of histamine, which can lead to bronchospasm and hypotension. redness of the skin, increased sweating, redness of the white membrane of the eyes. With repeated use of Omnopon for 1-2 weeks (sometimes for 2-3 days), addiction (weakening of the analgesic effect) and opioid drug dependence may develop. 1-2 days after stopping the use of the drug, signs of withdrawal syndrome may appear (mydriasis, yawning, muscle contractions, headache, sweating, vomiting, diarrhea, tachycardia, hyperthermia, hypertension and other vegetative symptoms), which requires treatment in a specialized department.

Overdose Symptoms: stuporous or comatose state, hypothermia, decreased blood pressure, respiratory depression is observed. A characteristic sign is pronounced constriction of the pupils (with significant hypoxia, the pupils may be dilated). Treatment: maintaining adequate pulmonary ventilation. Intravenous administration of the specific opioid antagonist naloxone in a dose of 0.4 to 2 mg quickly restores breathing. If there is no effect, the administration of naloxone is repeated after 2-3 minutes. The starting dose of naloxone for children is 0.01 mg/kg. The short duration of action of naloxone should be taken into account. It is also necessary to remember about the possibility of developing withdrawal syndrome when administering naloxone to patients with addiction to morphs and similar drugs - in such cases, the dose of the antagonist should be increased gradually.

Interaction with other drugs Under close supervision and in reduced doses, OMNOPON should be used against the background of the effects of anesthetics, hypnotics, and anxiolytics. antidepressants and antipsychotics to avoid excessive depression of the central nervous system and suppression of the activity of the respiratory center. OMNOPON should not be combined with narcotic analgesics from the group of partial agonists (buprenorphine, tramadol) and agonists-antagonists (nalbuphine, butorphanol) of opioid receptors due to the risk of weakening analgesia and the possibility of provoking withdrawal syndrome. The analgesic effect and undesirable effects of opioid agonists (promedol, fentanyl) in the therapeutic dose range are summarized with the effects of OMNOPONA.

Special instructions During the treatment period, it is necessary to refrain from engaging in potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
