General
- Type: Vasopressors
- Technically an inotrope as beta 2 stimulation causes vasodilation
- Should use in combination with a vasopressor (eg norepinephrine) to avoid hypotension
- Dosage Forms:
- Common Trade Names:
Adult Dosing
Dosing
- 2-20mcg/kg/min
- 10mcg works for most
- May use in peripheral IV
Rate of Titration
- Q2-5 min
Pediatric Dosing
Special Populations
- Pregnancy Rating: B
- Lactation:
- Unknown if Dobutamine passes into breast milk
- Renal Dosing
- Adult
- Not defined
- Pediatric
- Not defined
- Adult
- Hepatic Dosing
- Adult
- Not defined
- Pediatric
- Not defined
- Adult
Contraindications
- Allergy to class/drug
Adverse Reactions
- Tachyarrhythmias
- Myocardial ischemia
- Hypotension as β2 effect may result in vasodilation
- Caution if SBP <90
Serious
Common
Pharmacology[1]
- Half-life:
- 2 minutes
- Metabolism:
- In tissues and hepatically
- Excretion:
- Urine as metabolites
- Mechanism of Action:β1 stimulation with variable BP effects
Primary Receptor
- β1
- β2
Relative Effects
- ↑↑↑SV
- ↑↑HR → increases oxygen demand of heart → can worsen ischemia
- ↓SVR (transient, from β2 agonism)
Notes
Indications
- Cardiogenic shock
- initial agent in low-output heart failure without requiring BP support
- Tricyclic overdose
- septic shock with low cardiac output to improve blood flow
Indications by Condition
The following table is automatically generated from disease/condition pages across WikEM.
| Indication | Dose | Context | Route | Population |
|---|---|---|---|---|
| Coarctation of the aorta | 5-10mcg/kg/min IV | Inotropic support for CHF | IV | Pediatric |
| Congestive heart failure | 2-20 mcg/kg/min IV drip | Inotrope (1st line for hypotensive HF) | IV drip | Adult |
| Sepsis (main) | 2-20 mcg/kg/min | Inotrope for sepsis-related myocardial dysfunction | IV drip | Adult |
| Vasopressors | 2-5 mcg/kg/min, max 20 mcg/kg/min | Inotrope | IV drip | Adult |
| Vasopressors | 2-20mcg/kg/min | Inotrope for cardiogenic shock | IV | Adult |
