P51 Evaluating propranolol preparations for use in infantile haemangioma

Aim To evaluate oral liquid formulations of propranolol and to select the optimal preparation for use in Infantile Haemangioma.

Method Four oral liquid preparations of propranolol were considered:

A – an alcohol-free suspension prepared as a ‘special’ (the current treatment of choice)

B and C – generic solutions available in four different strengths

D – a French solution not marketed in the United Kingdom (UK)

Preparations were evaluated against six criteria:

  • Licensing status

  • Ease of purchase

  • Shelf life

  • Excipients

  • Ease of dosing

  • Cost

Results Licensing status: Preparation A is unlicensed and should not be used if a licensed product is suitable. Preparations B and C are licensed in children but not for Infantile Haemangioma. Preparation D has a European license for Infantile Haemangioma.

Ease of purchase: Preparation A is made to order but has a short lead time. Preparations B and C are available from wholesalers. No current importer for Preparation D was found.

Shelf life: The licensed preparations have 2–3 years shelf life. Preparation A has a 1 month shelf life.

Excipients: All excipients were considered. Aspartame, ethanol, maltitol, methylhydroxybenzoate, propylhydroxybenzoate, propylene glycol, saccharin sodium and Sunset Yellow can all cause adverse effects. The excipient most likely to cause problems was propylene glycol. This is eliminated by both renal excretion and liver metabolism but, in infants, these processes are immature and accumulation occurs with resultant toxicity. Preparation A contains no propylene glycol and can be used in children of all ages. Levels in Preparations B and C are safe for use in children over 1 month.1 The propylene glycol content of Preparation D could not be ascertained. Preparation B contained ethanol. Levels were below safety limits2 but ethanol competes with propylene glycol for metabolism via alcohol dehydrogenase increasing the risk of propylene glycol toxicity.

Ease of dosing: Dose volumes were calculated for a neonate (3.5 kg), a 6 month-old (7.6 kg) and a 1 year-old (9 kg). All preparations with strengths between 1 mg/ml and 3.75 mg/ml gave suitable dose volumes. Doses for Preparation D are expressed as propranolol base. In the UK, doses are expressed as propranolol hydrochloride. This could be confusing and lead to prescribing or dispensing errors.

Cost: Preparation A was more expensive than B or C. The cost of Preparation D could not be established.

Conclusions Although Preparation D is licensed for Infantile Haemangioma, its use would be complicated by difficulties in obtaining supplies, likely cost and the risk of confusion between propranolol base and hydrochloride when prescribing and dispensing. Preparations B and C are suitable for use in children over 1 month of age. Preparation C is recommended because it contains less propylene glycol and no alcohol. Preparation A should only be used in children under 28 days. Using Preparation C instead of Preparation A gives the benefits that a licensed preparation is used, dispensing delays are reduced and costs are reduced.
