Beta-Blocker Oral Liquid Formulations
Yes, propranolol is available as an FDA-approved oral liquid formulation specifically designed for pediatric use.
Available Oral Liquid Beta-Blocker
Propranolol hydrochloride oral solution (Hemangeol) is the only FDA-approved beta-blocker liquid formulation currently available in the United States 1. This formulation:
- Contains 4.28 mg/mL propranolol hydrochloride
- Was FDA-approved in March 2014
- Is specifically indicated for proliferating infantile hemangiomas requiring systemic therapy
- Can be dosed at 0.6 mg/kg twice daily initially, titrating to 1.7 mg/kg twice daily (3.4 mg/kg per day) 1
Clinical Context and Limitations
While propranolol oral solution exists as a commercial product, its FDA approval is specifically for infantile hemangiomas rather than traditional cardiovascular indications. However, propranolol can be used off-label for cardiovascular conditions in pediatrics when an oral liquid is needed.
Important considerations:
- For cardiovascular indications (hypertension, arrhythmias, angina), guidelines primarily reference oral tablets or intravenous formulations 2, 3
- Most adult cardiovascular guidelines list standard oral tablet dosing (e.g., propranolol 10-40 mg TID or QID) 3
- Carvedilol has been studied in experimental oral liquid formulations for pediatric use, showing good palatability and stability, but is not yet commercially available as a liquid 4
Alternative Beta-Blockers
No other beta-blockers are commercially available as oral liquids in the United States. The commonly used beta-blockers listed in cardiovascular guidelines are only available as:
- Tablets/capsules: metoprolol, atenolol, nadolol, bisoprolol, carvedilol 2, 3
- Intravenous only: esmolol 2, 3
Practical Solutions
If an oral liquid beta-blocker is needed for cardiovascular indications:
- Use propranolol oral solution (Hemangeol) off-label for cardiovascular conditions
- Compound a liquid formulation from tablets through a compounding pharmacy (though stability and palatability may be limited compared to commercial products)
- Consider crushing tablets and mixing with appropriate vehicles for immediate administration (not suitable for extended-release formulations)
The bottom line: Propranolol is the only beta-blocker with a commercially available oral liquid formulation in the US, though its FDA indication is for infantile hemangiomas rather than cardiovascular disease 1.
