Conversion of paroxysmal supraventricular tachycardia (psvt) to sinus rhythm Reconstitution Compatibility • No reconstitution required. • Available as a 3 mg/mL solution: 2 mL single-dose vial and PF syringe. Vials should be stored at room temperature. Don’t refrigerate as crystallization may occur. If crystallization has occurred, dissolve crystals by warming to room temperature. Physically compatible with NS, D5W and Lactated Ringer’s solutions. Routes of Administration. Intravenous Administration Policy. Continuous ECG monitoring during and for 3 - 5 minutes after administration and then until stable & Stability. Dosage. Potential Hazards Of Administration. Important Implications Initial Dose: 6 mg as a rapid intravenous push over 1 to 2 seconds followed by a 0.9% sodium chloride flush. Repeat Administration: 12 mg as a rapid intravenous push over 1 to 2 seconds followed by a 0.9% sodium chloride flush. A third dose of 12 mg may be administered if the first doses are not effective in 1 to 2 minutes. Light headness and dizziness as a result of decreased cerebral blood flowHeadache, Severe flushing, nausea, shortness of breath - Side effects will usually last only 1 to 2 minutes due to the very short half life of adenosine - First, second or third degree heart block as well as "transient" asystole- Patients will experience transient asystole. - May precipitate angina in patients with IHD as a result of coronary steal. 1 ICU Nurses Drug Index-2011 © Dr. P.K.

HYPERSENSITIVITY Urticaria, angioedema, bronchoconstriction and anaphylaxis. CARDIOVASCULAR Increased blood pressure Angina in patients with coronary artery disease Peripheral vasoconstriction, such as coronary or mesenteric vessels. Drugs which increase antidiuretic effect e.g., carbamazepine, chlorpropamide, indomethacin and oxcarbazine. 73 ICU Nurses Drug Index-2011 © Dr. P.K.

Compatible with D5W, NS, D5-1/2S, D5S, 1/2NS, RL and 20 mEq KCl Intermittent Infusion • Observe for signs of anaphylactoid reaction (i.e., chest tightness, dyspnea, faintness, flushing, nausea, sweating) for 10 minutes after the start of each dose. • Baseline serum electrolytes, creatinine, liver function tests and ECG. ADULT Loading dose: 6 mg/kg every 12 hours for 2 doses; followed by maintenance dose of 4 mg/kg every 12 hours. P/O - 40 kg or greater: 200 mg every 12 hours; increase to 300 mg every 12 hours if response inadequate. - less than 40 kg reduce the above dose to half PAEDIATRIC Exact paediatric dose not yet determined, but is believed to be greater than adult dosing. Loading dose: 6 mg/kg every 12 hours for 2 doses; followed by maintenance dose of 4 mg/kg every 12 hours has been used. Increased liver function tests, cholestatic jaundice, ARF OCULAR : photophobia, color changes, increased or decreased visual acuity, or blurred vision INFUSION RELATED HYPERSENSITIVITY REACTIONS • Anaphylactoid type reactions e.g. chest tightness, dyspnea, faintness, fever, flushing, nausea, pruritus, rash, sweating,Tachycardia. CARDIOVASCULAR • Tachycardia, hypertension, hypotension, vasodilation, peripheral oedema, • QTc prolongation (rare). CNS - Fever, chills, headache, hallucinations, dizziness. DERMATOLOGIC - Rash, pruritus, Photosensitivity – avoid sunlight. ENDOCRINE - Hypocalcemia, hypokalemia, hypomagnesaemia. GI - Nausea, vomiting, abdominal pain, diarrhoea, xerostomia • Interactions are numerous and potentially life threatening. Review drug profile at time of initiation and with any change in medication regimen. Contact Drug Information for more information. 74 ICU Nurses Drug Index-2011 © Dr. P.K.

Potential Hazards Of Administration. Important Implications Drug Interactions ZIDOVUDINE Antiretroviral agent Management of patients with human immunodeficiency virus (HIV) infection. • For prophylaxis against HIV transmission to baby during delivery. None required. Available as zidovudine 10 mg/mL - 20 mL amber vial. Compatible with D5W, NS, D5-½S and lactated Ringer's solutions. Stable in above solutions for at least 24 hours at room temperature and in the refrigerator. IV • Baseline CBC with differential then regularly thereafter. • Baseline serum creatinine. HIV- 1 - 2 mg/kg every 4 hours around the clock. Pregnancy: prophylaxis against HIV transmission to baby • 2 mg/kg/hour for 1 hour, then 1 mg/kg/hour up to umbilical cord clamping. RENAL IMPAIRMENT ADJUSTMENTS • For creatinine clearance (GFR) less than 10 mL/min, 1 mg/kg every 6-8 hours. HEMO/PERITONEAL DIALYSIS • Haemodialysis and CAPD: 1 mg/kg every 6-8 hours. • CRRT: 1 mg/kg every 6-8 hours. Headache, nausea, myalgia, insomnia Myopathy and myositis with pathologic changes. Lactic acidosis and severe hepatomegaly with steatosis (sometimes fatal) has been reported. HAEMATOLOGICAL - dose-limiting toxicity • Neutropenia: usually occurs after 6-8 weeks. • Anaemia: may occur as early as 2-4 weeks. HYPERSENSITIVITY - Rash, anaphylaxis (rare) • Any drug metabolised by glucuronidation (e.g. acetaminophen, diazepam, morphine); toxicity of both drugs may be increased. • Bone marrow depressants (e.g. dapsone, doxorubicin, flucytosine, vincristine): May cause additive or synergistic myelosuppression, dosage reduction may be required. • Ganciclovir: Synergistic myelosuppression, use combination with extreme caution. • Probenecid: Inhibits metabolism and excretion of zidovudine, may increase risk of toxicity. 75 ICU Nurses Drug Index-2011 © Dr. P.K.
