  In Postanesthetic Use Table I. * Dose not to exceed 3 grams/24 hours. Dosage for postanesthetic use—I.V. and infusion. I.V. Administration Recommended Dosage

  mg/kg Maximum total
  dose*
  mg/kg Single Injection 0.5-1 1.5 1.5 Repeat Injections
  (5 min. intervals) 0.5-1 1.5 2 Infusion 0.5-1 – 4 By I.V. Injection

  (See Table I. Dosage for postanesthetic use—I.V.)

  The recommended dose for I.V. administration is 0.5 – 1 mg/kg for a single injection and at 5-minute intervals. Careful observation of the patient during administration and for some time subsequently are advisable. The maximum total dosage by I.V. injection is 2 mg/kg.

  By Infusion

  The solution is prepared by adding 250 mg of doxapram (12.5 mL) to 250 mL of dextrose 5% or 10% in water or normal saline solution. The infusion is initiated at a rate of approximately 5 mg/minute until a satisfactory respiratory response is observed, and maintained at a rate of 1 to 3 mg/minute. The rate of infusion should be adjusted to sustain the desired level of respiratory stimulation with a minimum of side effects. The maximum total dosage by infusion is 4 mg/kg, or approximately 300 mg for the average adult.

  In the Management of Drug-Induced CNS Depression

  (See Table II. Dosage for drug-induced CNS depression.)

  Table II. * Mild Depression
  Class 0: Asleep, but can be aroused and can answer questions.
  Class 1: Comatose, will withdraw from painful stimuli, reflexes intact. † Moderate Depression
  Class 2: Comatose, will not withdraw from painful stimuli, reflexes intact.
  Class 3: Comatose, reflexes absent, no depression of circulation or respiration.
  Dosage for drug-induced CNS depression. METHOD ONE
  Priming dose single/repeat I.V. Injection METHOD TWO
  Rate of Intermittent I.V. Infusion Level of Depression mg/kg mg/kg/hr Mild* 1 1-2 Moderate† 2 2-3 Method One Using Single and/or Repeat Single I.V. Injections Give priming dose of 2 mg/kg body weight and repeat in 5 minutes. The priming dose for moderate depression is 2 mg/kg and the priming dose for mild depression is 1 mg/kg. Repeat same dose q 1 to 2h until patient wakens. Watch for relapse into unconsciousness or development of respiratory depression, since DOPRAM does not affect the metabolism of CNS-depressant drugs. If relapse occurs, resume injections q 1 to 2h until arousal is sustained, or total maximum daily dose (3 grams) is given. After maximum dose has been given (3 grams), allow patient to sleep until 24 hours have elapsed from first injection of DOPRAM, using assisted or automatic respiration if necessary. Repeat procedure the following day until patient breathes spontaneously and sustains desired level of consciousness, or until maximum dosage (3 grams) is given. Repetitive doses should be administered only to patients who have shown response to the initial dose. Failure to respond appropriately indicates the need for neurologic evaluation for a possible central nervous system source of sustained coma. Method Two By Intermittent I.V. Infusion Give priming dose as in Method One. If patient wakens, watch for relapse; if no response, continue general supportive treatment for 1 to 2 hours and repeat priming dose of DOPRAM. If some respiratory stimulation occurs, prepare I.V. infusion by adding 250 mg of DOPRAM (12.5 mL) to 250 mL of saline or dextrose solution. Deliver at rate of 1 to 3 mg/min (60 to 180 mL/hr) according to size of patient and depth of coma. Discontinue DOPRAM if patient begins to waken or at end of 2 hours. Continue supportive treatment for ½ to 2 hours and repeat Step b. Do not exceed 3 grams/day. Chronic Obstructive Pulmonary Disease Associated with Acute Hypercapnia One vial of doxapram (400 mg) should be mixed with 180 mL of dextrose 5% or 10% or normal saline solution (concentration of 2 mg/mL). The infusion should be started at 1 to 2 mg/minute (½ to 1 mL/minute); if indicated, increase to a maximum of 3 mg/minute. Arterial blood gases should be determined prior to the onset of doxapram’s administration and at least every half hour during the two hours of infusion to insure against the insidious development of CO2-RETENTION AND ACIDOSIS. Alteration of oxygen concentration or flow rate may necessitate adjustment in the rate of doxapram infusion. Predictable blood gas patterns are more readily established with a continuous infusion of doxapram. If the blood gases show evidence of deterioration, the infusion of doxapram should be discontinued. ADDITIONAL INFUSIONS BEYOND THE SINGLE MAXIMUM TWO HOUR ADMINISTRATION PERIOD ARE NOT RECOMMENDED.

  Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

  Diluent Compatibility

  Doxapram hydrochloride is compatible with 5% and 10% dextrose in water or normal saline.

  Incompatibility

  ADMIXTURE OF DOXAPRAM WITH ALKALINE SOLUTIONS SUCH AS 2.5% THIOPENTAL SODIUM, SODIUM BICARBONATE, FUROSEMIDE, OR AMINOPHYLLINE WILL RESULT IN PRECIPITATION OR GAS FORMATION.

  Doxapram is also not compatible with ascorbic acid, cefoperazone sodium, cefotaxime sodium, cefotetan sodium, cefuroxime sodium, folic acid, dexamethasone disodium phosphate, diazepam, hydrocortisone sodium phosphate, methylprednisolone sodium, or hydrocortisone sodium succinate.

  Admixture of doxapram and ticarcillin disodium results in an 18% loss of doxapram in 3 hours. When doxapram is mixed with minocycline hydrochloride, there is a loss of 8% of doxapram in 3 hours and a 13% loss of doxapram in 6 hours.
