Contra-indications

Aspirin is contraindicated in gout, breast feeding, haemophilia, and concurrent anticoagulant therapy.

4.4 Special warnings and special precautions for use

Administer with caution in the presence of allergic disease, renal or hepatic impairment, dehydration.

There is a possible association between aspirin and Reye’s syndrome when given to children with a fever. Reye’s syndrome is a very rare disease which affects the brain and liver, and can be fatal. For this reason aspirin should not be given to children aged under 16 years unless specifically indicated (eg for Kawasaki’s disease).

4.5. Interaction with other medicinal products and other forms of interaction

Aspirin antagonises the diuretic effect of spironolactone, potentiates the effect of heparin, increases the risk of bleeding with warfarin and acenocoumarol, increases the toxicity of methotrexate by delaying excretion, inhibits the effect of probenecid and sulfinpyrazone and increases the risk of toxicity of acetazolomide by reducing excretion. Antacids and corticosteroids reduce the effect of aspirin. Metoclopramide potentiates the effect of aspirin.

Concurrent administration of aspirin with other drugs that are known to increase bleeding time, for example anticoagulants and antiplatelet drugs such as clopidrogel and ticlopidine, or that are known to cause gastrointestinal irritation, for example NSAIDs, may increase the risk of haemorrhage and other gastrointestinal side effects.

4.6 Pregnancy and lactation

Do not administer at term or during lactation.

4.7 Effects on ability to drive and use machines

None known.

4.8


Undesirable effects

High incidence of gastro-intestinal irritation with slight asymptomatic blood loss, increased bleeding time, bronchospasm and skin reaction in hypersensitive patients. Association with Reye's Syndrome in children. Can lead to hearing disturbances (such as tinnitus), vertigo or mental confusion. Aspirin may precipitate bronchospasm and induce asthma attacks or other hypersensitivity reactions in susceptible individuals.

Other undesirable effects include:

Gastrointestinal ulceration, haematemesis, melaena, iron-deficiency anaemia, gastrointestinal bleeding

4.9 Overdose

Employ gastric lavage, forced alkaline diuresis and supportive therapy. Restoration of acid-base balance may be necessary.

5 PHARMACOLOGICAL PROPERTIES

5.1    Pharmacodynamic properties

Absorption of non-ionised aspirin occurs in the stomach. Acetylsalicylates and salicylates are also readily absorbed from the intestine. Hydrolysis to salicylic acid occurs rapidly in the intestine and in the circulation. Salicylates are extensively bound to plasma proteins; aspirin to a lesser degree. Aspirin is an inhibitor of the enzyme cyclo-oxygenase which results in the inhibition of the biosynthesis of prostaglandins.

5.2    Pharmacokinetic properties

Aspirin and salicylates are rapidly distributed to all body tissues; they appear in milk and cross the placenta. The rate of excretion of the aspirin varies with the pH of the urine, increasing as the pH rises and being greatest at pH 7.5 and above. Aspirin is also excreted as salicylic acid and as the glucuronide conjugate and as salicyluric and gentisic acids.

5.3 Preclinical safety data

Preclinical information has not been included because the safety profile of Aspirin has been established after many years of clinical use. Please refer to section 4.
