4 CLINICAL PARTICULARS
4.1 Therapeutic indications
• For the treatment of chronic constipation.
Resolving faecal impaction, defined as refractory constipation with faecal loading of the rectum and/or colon.
4.2 Posology and method of administration
Chronic constipation
Adults, adolescents and the elderly: 1 -3 sachets daily in divided doses. Normal dose for most patients is 1-2 sachets per day. Depending on the individual response 3 sachets per day might be needed.
A course of treatment for constipation does not normally exceed 2 weeks, although this can be repeated if required.
For extended use, the lowest effective dose should be used.
Children below 12 years old: Not recommended. Alternative products are available for children.
Patients with renal insufficiency: No dosage change is necessary for the treatment of chronic constipation.
Faecal impaction
A course of treatment for faecal impaction does not normally exceed 3 days.
Adults, adolescents and the elderly: 8 sachets daily, all of which should be consumed within a 6 hour period.
Children below 12 years old: Not recommended. Alternative products are available for children.
Patients with impaired cardiovascular function: For the treatment of faecal impaction the dose should be divided so that no more than 2 sachets are taken in any one hour.
Patients with renal insufficiency: No dosage change is necessary for the treatment of faecal impaction.
Administration
Each sachet should be dissolved in 125 ml water. For use in faecal impaction 8 sachets may be dissolved in 1 litre of water.
4.3 Contraindications
Intestinal perforation or obstruction due to structural or functional disorder of the gut wall, ileus, severe inflammatory conditions of the intestinal tract, such as Crohn's disease and ulcerative colitis and toxic megacolon.
Hypersensitivity to the active substances or to any of the excipients.
4.4 Special warnings and precautions for use
Diagnosis of impaction/faecal loading of the rectum should be confirmed by physical or radiological examination of the abdomen and rectum.
The cause of constipation should be investigated if daily use of laxatives is necessary. Patients using this preparation should seek medical advice if there is no improvement after two weeks.
Long term use can be necessary in serious chronical or refractory constipation due to i.e. multiple sclerosis (MS) or Parkinson’s disease, or constipation induced by drugs, especially opioides or antimuscarine products.
If patients develop any symptoms indicating shifts of fluids/electrolytes (e.g. oedema, shortness of breath, increasing fatigue, dehydration, cardiac failure) treatment should be stopped immediately and electrolytes measured and any abnormality should be treated appropriately.
The absorption of other medicinal products could transiently be reduced due to an increase in gastro-intestinal transit rate induced by this medicinal product (see section 4.5).
There is no clinical data on the use of Compound Macrogol 13.7g powder for oral solution in children, therefore it is not recommended.
4.5 Interaction with other medicinal products and other forms of interaction
Macrogol raises the solubility of medicinal products that are soluble in alcohol and relatively insoluble in water.
There is a possibility that the absorption of other medicinal products could be transiently reduced during use with this medicinal product (see section 4.4).
4.6 Pregnancy and lactation
Pregnancy:
There is no documented experience from the use of macrogol in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/fetal reproductive development, delivery or postnatal development (see section 5.3). As Macrogol has a molecular weight above 3000 da very little if any will be absorbed. Therefore it seems unlikely that the use of this product will cause problems during pregnancy. For this reason this product can be used during pregnancy, if necessary.
Breast-feeding:
There is no documented experience from the use of macrogol during breastfeeding. Macrogol with a molecular weight above 3000 da will not or hardly be resorbed. For this reason this product can be used during breast-feeding, as far as known.
4.7 Effects on ability to drive and use machines
Compound Macrogol 13.7g powder for oral solution has no influence on the ability to drive and use machines.
4.8 Undesirable effects
The frequency of the adverse reactions listed below is defined using the following convention: very common (>1/10); common (>1/100 to <1/10); uncommon (>1/1,000 to <1/100); rare (>1/10,000 to <1/1,000); and very rare (<1/10,000); not known (cannot be estimated from the available data).
Reactions related to the gastrointestinal tract are the most common to occur.
These reactions may occur as a consequence of expansion of the contents of the gastrointestinal tract, and an increase in motility due to the pharmacological effects of the product. Mild diarrhoea usually responds to dose reduction.

5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Osmotically acting laxatives. ATC code: A06A D65
Macrogol 3350 acts by virtue of its osmotic action in the gut, which induces a laxative effect. Macrogol 3350 increases the stool volume, which triggers colon motility via neuromuscular pathways. The physiological consequence is an improved propulsive colonic transportation of the softened stools and a facilitation of the defaecation. Electrolytes combined with macrogol 3350 are exchanged across the intestinal barrier (mucosa) with serum electrolytes and excreted in faecal water without net gain or loss of sodium, potassium and water.
For the indication of faecal impaction controlled comparative studies have not been performed with other treatments (e.g. enemas). In a non-comparative study in 27 adult patients, macrogol with electrolytes cleared the faecal impaction in 12/27 (44%) after 1 day's treatment; 23/27 (85%) after 2 days' treatment and 24/27 (89%) at the end of 3 days.
Clinical studies in the use of macrogol with electrolytes in chronic constipation have shown that the dose needed to produce normal formed stools tends to reduce over time. Many patients respond to between 1 and 2 sachets a day, but this dose should be adjusted depending on individual response.
5.2 Pharmacokinetic properties
Macrogol 3350 is unchanged along the gut. It is virtually unabsorbed from the gastro-intestinal tract. Any macrogol 3350 that is absorbed is excreted via the urine.
5.3 Preclinical safety data
Preclinical data do not indicate a special risk for humans. These data are originated from conventional studies in the field of pharmacology, repeated dose toxicity, genotoxicity and reproductive toxicity.
