NSAID treatment who areH. pyloripositive and have
dyspepsia or a history of gastric or duodenal ulcer,
eradication ofH. pylorimay reduce the overall risk of
ulceration.
If the NSAID can bediscontinuedin a child who has
developed an ulcer, a proton pump inhibitor usually
produces the most rapid healing; alternatively the ulcer can
be treated with an H 2 -receptor antagonist.
IfNSAID treatment needs to continue, the ulcer is treated
with a proton pump inhibitor.

CHELATORS

Chelates and complexes


Sucralfate
Sucralfate below is a complex of aluminium hydroxide and
sulfated sucrose that appears to act by protecting the
mucosa from acid-pepsin attack; it has minimal antacid
properties.

Prophylaxis of stress ulceration in child under intensive
care
▶BY MOUTH

lUNLICENSED USENot licensed for use in children under
15 years. Tablets not licensed for prophylaxis of stress
ulceration.
lCAUTIONSPatients under intensive care (Important:
reports of bezoar formation)
CAUTIONS, FURTHER INFORMATION
▶Bezoar formationFollowing reports of bezoar formation
associated with sucralfate, caution is advised in seriously
ill patients, especially those receiving concomitant enteral
feeds or those with predisposing conditions such as
delayed gastric emptying.
lINTERACTIONS→Appendix 1 : sucralfate
lSIDE-EFFECTS
▶Common or very commonConstipation
▶UncommonDry mouth.nausea
▶Rare or very rareBezoar.rash
▶Frequency not knownBack pain.bone disorders.diarrhoea
.dizziness.drowsiness.encephalopathy.flatulence.
headache.vertigo
lPREGNANCYNo evidence of harm; absorption from gastro-
intestinal tract negligible.
lBREAST FEEDINGAmount probably too small to be
harmful.
lRENAL IMPAIRMENTUse with caution; aluminium is
absorbed and may accumulate.

lDIRECTIONS FOR ADMINISTRATIONAdministration of
sucralfate and enteral feeds should be separated by 1 hour
and for administration bymouth, sucralfate should be
given^1 hour before meals.Oral suspensionblocksfine-
bore feeding tubes. Crushedtabletsmay be dispersed in
water.
lPRESCRIBING AND DISPENSING INFORMATIONFlavours of
oral liquid formulations may include aniseed and caramel.

lMEDICINAL FORMS
There can be variation in the licensing of different medicines
containing the same drug. Forms available from special-order
manufacturers include: tablet, oral suspension

H 2 -RECEPTOR ANTAGONISTS


H 2 -receptor antagonists


Overview
Histamine H 2 -receptor antagonistshealgastric and
duodenal ulcersby reducing gastric acid output as a result of
histamine H 2 -receptor blockade; they are also used to relieve
symptoms ofdyspepsiaandgastro-oesophageal reflux disease.
H 2 -receptor antagonists should not normally be used for
Zollinger–Ellison syndromebecause proton pump inhibitors
are more effective.
Maintenance treatment with low doses has largely been
replaced inHelicobacter pyloripositive children by
eradication regimens.
H 2 -receptor antagonist therapy can promote healing of
NSAID-associated ulcers.
Treatment with a H 2 -receptor antagonist has not been
shown to be beneficial in haematemesis and melaena, but
prophylactic use reduces the frequency of bleeding from
gastroduodenal erosions in hepatic coma, and possibly in other
conditions requiring intensive care. Treatment also reduces
the risk ofacid aspirationin obstetric patients at delivery
(Mendelson’s syndrome).
H 2 -receptor antagonists are also used to reduce the
degradation of pancreatic enzyme supplements in children
with cysticfibrosis.
