4.8 Undesirable Effects

The following adverse reactions have been reported with pseudoephedrine:

Psychiatric disorders

Common (>1/100 to <1/10): nervousness, insomnia

Uncommon (>1/1,000 to <1/100): agitation, restlessness

Rare (>1/10,000 to <1/1000): hallucinations (particularly in children)

Nervous System Disorders

Common (>1/100 to <1/10): dizziness

Cardiac disorders

Rare (>1/10,000 to <1/1000): tachycardia, palpitations,

Vascular disorders

Rare (>1/10,000 to <1/1000): increased blood pressure*

*Increases in systolic blood pressure have been observed. At therapeutic doses, the effects of pseudoephedrine on blood pressure are not clinically significant.

Gastrointestinal disorders

Common (>1/100 to <1/10): dry mouth, nausea, vomiting

Skin and subcutaneous tissue disorders

Rare (>1/10,000 to <1/1000): rash, allergic dermatitis*

Renal and urinary disorders

**Urinary retention is most likely to occur in those with bladder outlet obstruction, such as prostatic hypertrophy.

4.9 Overdose

Pseudoephedrine Hydrochloride

Symptoms

As with other sympathomimetics pseudoephedrine overdose will result in symptoms due to central nervous system and cardiovascular stimulation e.g. excitement, irritability, restlessness, tremor, hallucinations, hypertension, palpitations, arrhythmias and difficulty with micturition. In severe cases, psychosis, convulsions, coma and hypertensive crisis may occur. Serum potassium levels may be low due to extracellular to intracellular shifts in potassium.

Management

Treatment should consist of standard supportive measures. Beta-blockers should reverse the cardiovascular complications and the hypokalaemia.

5. Pharmacological Properties 5.1 Pharmacodynamic Properties

ATC Code R01B A02.

Pseudoephedrine has direct and indirect sympathomimetic activity and is an orally-effective decongestant of the mucous membranes of the upper respiratory tract, especially the nasal mucosa and sinuses.

5.2 Pharmacokinetic Properties

The product is a prolonged-release capsule presentation having a therapeutic action of up to 12 hours.

Pseudoephedrine is readily and completely absorbed from the gastrointestinal tract after oral administration, with no presystemic metabolism. Peak plasma levels are achieved after 1

The volume of distribution ranges from 2.64 to 3.51 l/kg in both single and multiple dose studies.

There is little metabolism of pseudoephedrine in man with approximately 90% being excreted in the urine unchanged. Approximately 1% is eliminated by hepatic metabolism, by N

As a weak base, the extent of renal excretion is dependent on urinary pH. At low urinary pH, tubular resorption is minimal and urine flow rate will not influence clearance of the drug. At high pH (>7.0), pseudoephedrine is extensively reabsorbed in the renal tubule and renal clearance will depend on urine flow rate.

Hepatic disease is unlikely to affect the pharmacokinetics of the drug. Renal impairment will result in increased plasma levels.

5.3 Preclinical Safety Data

There are no preclinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
