Description

11 DESCRIPTION Vasopressin in Sodium Chloride Injection contains vasopressin, a polypeptide hormone. The chemical name of vasopressin is Cyclo (1-6) L-Cysteinyl-L-Tyrosyl-L-Phenylalanyl-L-Glutaminyl-L-Asparaginyl-L-Cysteinyl-L-Prolyl-L-Arginyl-L-Glycinamide. It is a white to off-white amorphous powder, freely soluble in water. The structural formula is: Molecular Formula: C 46 H 65 N 15 O 12 S 2 Molecular Weight: 1084.23 Vasopressin in Sodium Chloride Injection is a sterile, aqueous solution of synthetic arginine vasopressin for intravenous administration. Each 100 mL contains 20 units (0.2 units/mL) or 40 units (0.4 units/mL) of vasopressin. Each 100mL also contains 900 mg Sodium Chloride, 33.6 mg Sodium DL-Lactate, and Water for Injection. pH may have been adjusted with sodium hydroxide and/or hydrochloric acid. It has a pH of 3.6 – 4.0. Vasopressin Structural Formula

What Is Vasopressin In 0.9% Sodium Chloride Used For?

1 INDICATIONS AND USAGE Vasopressin in Sodium Chloride Injection is indicated to increase blood pressure in adults with vasodilatory shock who remain hypotensive despite fluids and catecholamines. Vasopressin in Sodium Chloride Injection is indicated to increase blood pressure in adults with vasodilatory shock who remain hypotensive despite fluids and catecholamines. ( 1 )

Dosage and Administration

2 DOSAGE AND ADMINISTRATION

  • Post-cardiotomy shock: 0.03 units/minute to 0.1 units/minute by intravenous infusion. ( 2.1 )
  • Septic shock: 0.01 units/minute to 0.07 units/minute by intravenous infusion. ( 2.1 ) 2.1 Administration This product does not require dilution prior to administration. In general, titrate to the lowest dose compatible with a clinically acceptable response. The recommended starting dose is: Post-cardiotomy shock: 0.03 units/minute by intravenous infusion Septic Shock: 0.01 units/minute by intravenous infusion Titrate up by 0.005 units/minute at 10- to 15-minute intervals until the target blood pressure is reached. There are limited data for doses above 0.1 units/minute for post-cardiotomy shock and 0.07 units/minute for septic shock. Adverse reactions are expected to increase with higher doses. After target blood pressure has been maintained for 8 hours without the use of catecholamines, taper vasopressin injection by 0.005 units/minute every hour as tolerated to maintain target blood pressure. Inspect visually for any particulate matter and discoloration prior to administration. Discard Unused Portion Do not add supplemental medication or additive

    • Side Effects (Adverse Reactions)

    6 ADVERSE REACTIONS The following adverse reactions associated with the use of vasopressin were identified in the literature. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to estimate reliably their frequency or establish a causal relationship to drug exposure. Bleeding/lymphatic system disorders: Hemorrhagic shock, decreased platelets, intractable bleeding Cardiac disorders: Right heart failure, atrial fibrillation, bradycardia, myocardial ischemia Gastrointestinal disorders: Mesenteric ischemia Hepatobiliary: Increased bilirubin levels Renal/urinary disorders: Acute renal insufficiency Vascular disorders: Distal limb ischemia Metabolic: Hyponatremia Skin: Ischemic lesions Postmarketing Experience Reversible diabetes insipidus [ see Warnings and Precautions (5.2) ] The most common adverse reactions include decreased cardiac output, bradycardia, tachyarrhythmias, hyponatremia and ischemia (coronary, mesenteric, skin, digital).

    Drug Interactions

    7 DRUG INTERACTIONS

  • Pressor effects of catecholamines and Vasopressin in Sodium Chloride Injection are expected to be additive. ( 7.1 )
  • Indomethacin may prolong effects of Vasopressin in Sodium Chloride Injection. ( 7.2 )
  • Co-administration of ganglionic blockers or drugs causing SIADH (syndrome of inappropriate antiduretic hormone secretion) may increase the pressor response. ( 7.3 , 7.4 )
  • Co-administration of drugs causing diabetes insipidus may decrease the pressor response. ( 7.5 ) 7.1 Catecholamines Use with catecholamines is expected to result in an additive effect on mean arterial blood pressure and other hemodynamic parameters. Hemodynamic monitoring is recommended; adjust the dose of vasopressin as needed. 7.2 Indomethacin Use with indomethacin may prolong the effect of Vasopressin in Sodium Chloride Injection on cardiac index and systemic vascular resistance. Hemodynamic monitoring is recommended; adjust the dose of vasopressin as needed [ see Clinical Pharmacology (12.3) ] . 7.3 Ganglionic Blocking Agents Use with ganglionic blocking agents may increase the effect of Vasopressin in Sodium Chloride Injection on mean arterial blood pressure. Hemodynamic monitoring is recommended; adjust the dose of vasopressin as needed [ see Clinical Pharmacology (12.3) ] . 7.4 Drugs Suspected of Causing SIADH Use with drugs suspected of causing SIADH (e.g., SSRIs, tricyclic antidepressants, haloperidol, chlorpropamide, enalapril, methyldopa, pentamidine, vincristine, cyclophosphamide, ifosfamide, felbamate) may increase the pressor effect in addition to the antidiuretic effect of Vasopressin in Sodium Chloride Injection. Hemodynamic monitoring is recommended; adjust the dose of vasopressin as needed. 7.5 Drugs Suspected of Causing Diabetes Insipidus Use with drugs suspected of causing diabetes insipidus (e.g., demeclocycline, lithium, foscarnet, clozapine) may decrease the pressor effect in addition to the antidiuretic effect of Vasopressin in Sodium Chloride Injection. Hemodynamic monitoring is recommended; adjust the dose of vasopressin as needed.

    • Contraindications

    4 CONTRAINDICATIONS Vasopressin in Sodium Chloride Injection is contraindicated in patients with a known allergy or hypersensitivity to 8-L-arginine vasopressin.

  • Vasopressin in Sodium Chloride Injection is contraindicated in patients with known allergy or hypersensitivity to 8-L-arginine vasopressin. ( 4 )

    • Pregnancy and Breastfeeding

    8.1 Pregnancy Risk Summary There are no available data on Vasopressin in Sodium Chloride Injection use in pregnant women to inform a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted. Clinical Considerations Dose Adjustments During Pregnancy and the Postpartum Period: Because of increased clearance of vasopressin in the second and third trimester, the dose of Vasopressin in Sodium Chloride Injection may need to be increased [ see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) ]. Maternal Adverse Reactions: Vasopressin in Sodium Chloride Injection may produce tonic uterine contractions that could threaten the continuation of pregnancy.

    Overdosage

    10 OVERDOSAGE Overdosage with Vasopressin in Sodium Chloride Injection can be expected to manifest as consequences of vasoconstriction of various vascular beds (peripheral, mesenteric, and coronary) and as hyponatremia. In addition, overdosage may lead less commonly to ventricular tachyarrhythmias (including Torsade de Pointes), rhabdomyolysis, and non-specific gastrointestinal symptoms. Direct effects will resolve within minutes of withdrawal of treatment.
