Insights
Infants treated for infantile hemangioma with propranolol experienced severe agitation and diarrhea. This may be linked to prior in utero opioid exposure causing increased beta-adrenergic receptor sensitivity.
Area of Science:
- Pediatric pharmacology
- Neonatal neuroscience
- Pharmacogenetics
Background:
- Infantile hemangiomas are common vascular tumors in infants.
- Propranolol, a beta-adrenergic blocker, is the standard treatment.
- Neonatal Abstinence Syndrome (NAS) is associated with in utero opioid exposure.
Observation:
- Three infants with infantile hemangioma developed severe agitation and diarrhea after propranolol treatment.
- All infants had a history of in utero opioid exposure and NAS.
Findings:
- A potential link between in utero opioid exposure and adverse reactions to propranolol in infants is suggested.
- Chronic opioid exposure may lead to upregulation of central nervous system beta-2 adrenergic receptors.
Implications:
- This finding may inform clinical management of infants with infantile hemangioma and a history of NAS.
- Further research is needed to elucidate the mechanisms of beta-adrenergic receptor sensitivity in this population.
- Consideration of pre-existing conditions like NAS is crucial when initiating propranolol therapy.
Abstract:
We report three infants with infantile hemangioma who experienced severe agitation and diarrhea following propranolol administration. Propranolol, a non-selective β-adrenergic receptor blocker, is the first-line treatment for infantile hemangiomas. All three infants were exposed to opioids in utero and experienced neonatal abstinence syndrome at birth. We hypothesize that chronic opioid exposure in utero may cause protracted upregulation of β2-adrenergic receptors in the central nervous system, resulting in increased susceptibility to adverse reactions to propranolol.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
