Section 4.1, Therapeutic indications

Section 4.2, Posology and method of administration

 

Children Paediatric population

 

Initial daily dosage should provide 1- 3 mg of spironolactone per kilogram body weight

given in divided doses. Dosage should be adjusted on the basis of response and tolerance (see

sections 4.3, and 4.4 and 6.6). If necessary a suspension may be prepared by crushing Aldactone

If necessary a suspension may be prepared by crushing Aldactone tablets

 

Section 4.3, Contraindications

 

Spironolactone is contraindicated in adult and paediatric patients with the following:

(…)

·         paediatric patients with moderate to severe renal impairment

 

Spironolactone is contraindicated in paediatric patients with moderate to severe renal impairment.

(…)

 

Section 4.4, Special warnings and precautions for use

 

Potassium-sparing diuretics should be used with caution in hypertensive paediatric patients with mild renal insufficiency because of the risk of hyperkalaemia. (Spironolactone is contraindicated for use in paediatric patients with moderate or severe renal impairment; see section 4.3).

 

Section 5.1, Pharmacodynamic properties

 

Paediatric population:

 

There is a lack of substantive information from clinical studies on spironolactone in children.

This is a result of several factors: the few trials that have been performed in the paediatric population, the use of spironolactone in combination with other agents, the small numbers of patients evaluated in each trial, and the different indications studied. The dosage recommendations for paediatrics are based upon clinical experience and case studies documented in the scientific literature.

 

Section 5.2, Pharmacokinetic properties

 

Paediatric population:

There are no pharmacokinetic data available in respect of use in paediatric population. The dosage recommendations for paediatrics are based upon clinical experience and case studies documented in the scientific literature.
