Nalbuphine solution for injection, 1 ml in ampoules, 20 mg/ml, 5 pcs.


Pharmacological properties of the drug Nalbuphine

A synthetic agonist-antagonist of opioid receptors (agonist of κ- and antagonist of μ-opioid receptors) of the phenanthrene series, structurally close to both naloxone and oxymorphone. Activates the endogenous antinociceptive system through κ-opiate receptors, disrupts the interneuronal transmission of pain impulses at various levels of the central nervous system. By influencing the higher parts of the brain, it changes the emotional coloring of pain. Inhibits conditioned reflexes, has a sedative effect, causes dysphoria, miosis, and stimulates the vomiting center. To a lesser extent than morphine, promedol, fentanyl, depress the respiratory center and affect the motility of the digestive tract. Does not affect hemodynamics. The risk of developing addiction and opioid dependence with controlled use is significantly lower than for opioid agonists. With intravenous administration, the effect develops within a few minutes, with intramuscular administration - after 10–15 minutes. The maximum effect occurs after 30–60 minutes, duration of action is 3–6 hours. When administered orally, it is 4–5 times less active than when administered intramuscularly. The time to reach maximum concentration with intramuscular administration is 0.5–1 hour. Metabolized in the liver. It is excreted in the form of metabolites with bile and excreted in small quantities by the kidneys. Penetrates the placental barrier and can cause respiratory depression in the newborn during the postpartum period. Less than 1% is excreted in breast milk. The half-life is 2.5–3 hours.

    Pharmacological properties

    Pharmacodynamics.

    Nalbuphine is an opioid analgesic of the opioid receptor agonist-antagonist group (it is a kappa receptor agonist and a mu receptor antagonist). It disrupts the interneuronal transmission of pain impulses at various levels of the central nervous system, affecting the higher parts of the brain. Inhibits conditioned reflexes, has a sedative effect, causes dysphoria, miosis, and stimulates the vomiting center. To a lesser extent than morphine, promedol, fentanyl disrupts the respiratory center and affects the motility of the gastrointestinal tract. Does not affect hemodynamics. The risk of developing addiction and opioid dependence with controlled use is significantly lower than for opioid antagonists. When administered intravenously, the effect develops within a few minutes; when administered intravenously, the effect develops within 10-15 minutes. The maximum effect is after 30-60 minutes, duration of action is 3-6 hours.

    Pharmacokinetics.

    The drug has a rapid analgesic effect. The time to reach the maximum concentration of the drug in the blood upon administration is 0.5-1 hour. Metabolized in the liver. It is excreted in the form of metabolites in bile and in small amounts in urine. Passes through the placental barrier and during childbirth can cause respiratory depression in the newborn. Passes into breast milk. The half-life is 2.5 - 3:00.

    Indications

    Pain syndrome of strong and moderate intensity; as an additional means during anesthesia, to reduce pain in the pre- and postoperative period, pain relief during childbirth.

    Contraindications

    Hypersensitivity to nalbuphine hydrochloride or to any of the ingredients of the drug. The drug should not be used in cases of respiratory depression or severe depression of the central nervous system, increased intracranial pressure, head trauma, acute alcohol intoxication, or alcoholic psychosis. Epileptic syndrome acute surgical diseases of the abdominal organs (before diagnosis) surgical interventions on the hepatobiliary system (spasm of the sphincter of Oddi is possible) drug dependence on morphine-like drugs (morphine, promedol, fentanyl) - the possibility of developing withdrawal syndrome; diarrhea due to pseudomembrane colitis caused by cephalosporins, lincosamines, penicillins; toxic dyspepsia.

    With caution: old age, cachexia, liver and kidney failure, respiratory failure (including chronic obstructive pulmonary diseases, uremia), premature birth and possibly fetal immaturity, cholelithiasis, severe inflammatory bowel disease, bronchial asthma, arrhythmia, arterial hypertension, hypothyroidism, prostatic hyperplasia, urethral stenosis, suicidal tendencies, emotional lability; weakened patients. It is not recommended to use the drug without appropriate diagnostics for surgical abdominal syndrome, since nalbuphine can mask its manifestations.

    Special security measures.

    Nalbuphine should only be used as an adjuvant for general anesthesia by a specially trained specialist. Safety precautions regarding the possible occurrence of respiratory depression, namely naloxone, intubation and mechanical ventilation equipment, must be kept on guard.

    Interaction with other drugs and other types of interactions.

    Under close supervision and in reduced doses, the drug should be used against the background of the action of anesthesia, hypnotics, anxiolytics, antidepressants and antipsychotics to prevent excessive depression of the central nervous system and suppression of the activity of the respiratory center. Alcohol also enhances the inhibitory effect of nalbuphine on the central nervous system. The drug should not be used together with other narcotic analgesics due to the risk of weakening the analgesic effect and the possibility of provoking withdrawal syndrome in patients with addiction to opioids.

    Concomitant use of nalbuphine with phenothiazine derivatives and penicillin preparations may increase nausea and vomiting.

    Medicines with anticholinergic activity, antidiarrheals, incl. loperamide, increase the risk of developing constipation to intestinal obstruction, urinary retention and depression of the central nervous system. Strengthens the hypotensive effect of drugs that lower blood pressure, incl. ganglion blockers, diuretics. Reduces the effectiveness of metoclopramide. Caution should be used together with MAO inhibitors due to possible overexcitation or inhibition with the development of hyper- or hypotensive crises (initially, to assess the effect of interaction, the dose should be reduced to ¼ of the recommended).

    Features of application

    The drug should be used with caution in emotionally unstable patients. In patients with drug addiction, the drug can cause an acute withdrawal attack. When used simultaneously with other morphine derivatives, physical and mental dependence is possible during prolonged use. Sudden cessation of nalbuphine use may cause withdrawal symptoms with prolonged use. It is not recommended to use this drug in an outpatient setting due to the risk of daytime sleepiness.

    For dosing Nalbuphine Injection 10 mg, solution for injection 10 mg/ml, sodium content

    2.84 mg/ml in each ampoule; for dosing Nalbuphine Injection 20 mg, solution for injection 20 mg/ml, sodium content is 2.447 mg/ml in each ampoule. This should be taken into account when used in patients on a strict low sodium diet.

    Nalbuphine has a moderate ability to cause respiratory depression, so its use may provoke the development of respiratory failure.

    Due to the fact that the drug is metabolized in the liver and excreted by the kidneys, the need to use nalbuphine in patients with hepatic and/or renal insufficiency should be carefully considered, and if necessary, reduce the dose and carefully monitor the patient’s condition.

    When using nalbuphine in patients who are planning surgical intervention for surgical pathology of the digestive system, one should keep in mind the high risk of developing spasm of the sphincter of Oddi.

    In morphine-dependent individuals or patients who have undergone morphine therapy, a withdrawal syndrome may occur due to the antagonistic properties of nalbuphine hydrochloride. Nalbuphine may interfere with enzymatic laboratory tests used to determine drug dependence.

    It is not recommended to use the drug without appropriate diagnostics for surgical abdominal syndrome, since nalbuphine hydrochloride can mask its manifestations.

    Use during pregnancy or breastfeeding.

    Due to the lack of research, the drug should not be prescribed during pregnancy and breastfeeding.

    The drug should only be used during childbirth for pain relief. After using the drug, the mother should constantly monitor the following indicators in newborns: respiratory depression, apnea, bradycardia, arrhythmia. These effects can be prevented by giving the pregnant woman naloxone during labor.

    The ability to influence the reaction rate when driving vehicles or other mechanisms.

    During treatment with nalbuphine, you should refrain from driving vehicles and operating machinery.

    Directions for use and doses

    Use the drug intravenously and intramuscularly.

    The dosage should correspond to the intensity of pain, the physical condition of the patient and take into account the interaction with other concomitantly used drugs. The dose of the drug and the frequency of administration should be carefully calculated to avoid drug dependence. For pain relief, the usual recommended dose is 0.15-0.3 mg per 1 kg of body weight; if necessary, administration can be repeated every 4-6 hours.

    Patients with opiate dependence may develop withdrawal symptoms (withdrawal) when taking nalbuphine. In this case, it is necessary to prescribe morphine intravenously slowly with a gradual increase in dose until the pain disappears. If the patient was receiving morphine, meperidine, codeine or another opioid analgesic with a similar duration of activity before prescribing nalbuphine, it is necessary to first prescribe nalbuphine at a dose of 25% of the patient's required dose and monitor for the possible occurrence of withdrawal symptoms (abdominal cramps, nausea, vomiting, lacrimation, rhinorrhea , anxiety, excitability, hyperthermia or piloerection). If withdrawal symptoms do not occur, the dose of nalbuphine should be gradually increased at the recommended intervals until the required level of pain relief is achieved.

    The maximum single dose for adults is 0.3 mg per 1 kg of body weight, the maximum daily dose is 2.4 mg per 1 kg of body weight. The duration of use of nalbuphine depends on the patient's condition and should be as short as possible to avoid mental or physical dependence.

    For myocardial infarction, 20 mg of the drug is injected slowly into a vein is often sufficient, but the dose may need to be increased to 30 mg. In the absence of clear positive dynamics of the pain syndrome - 20 mg again after 30 minutes.

    When using nalbuphine as an adjuvant for anesthesia, higher doses are required than for pain relief. For premedication - 100-200 mcg/kg body weight. When conducting intravenous anesthesia: for induction of anesthesia - 0.3-1 mg / kg for 10-15 minutes, for maintaining anesthesia 250-500 mcg / kg slowly, every 30 minutes.

    For pain relief during childbirth, the drug should be used in a dose of 20 mg intramuscularly.

    Prescribe the drug with caution to elderly patients, with general exhaustion or poor respiratory function. In this case, use should be started with the minimum effective doses due to the more frequent occurrence of adverse reactions.
