3 PHARMACEUTICAL FORM

Powder for oral solution in sachet.

White powder, free of large agglomerates, with an odour and taste of lemon, packed in a sachet for the preparation of

an oral solution.

4 CLINICAL PARTICULARS

4.1 Therapeutic Indications

Symptomatic treatment of constipation in adults and children aged 8 years and above.

An organic disorder should have been ruled out before initiation of treatment with Macrosoft. Macrosoft should remain

a temporary adjuvant treatment to appropriate lifestyle and dietary management of constipation, with a maximum 3-

months treatment course in children. If symptoms persist despite associated dietary measures, an underlying cause

should be suspected and treated.

4.2 Posology and method of administration

Posology

It is generally recommended to consider healthy lifestyle measures such as adequate hydration, physical activity, and

increased natural fibre intake. In case the symptoms persist or get worse, a physician should be consulted.

Adults

1 to 2 sachets (10 to 20 g macrogol 4000) per day, preferably taken as a single dose in the morning.

Paediatric population

~ Children

8 years and adolescents: 1 to 2 sachets (10 to 20 g macrogol 4000) per day, preferably taken as a single

dose in the morning.

~ Children (<8 years):

Macrosoft is not recommended for use in children below the age of 8 years.

The daily dose should be adapted as required to produce regular soft stools and may range from one sachet every other

day (especially in children) up to 2 sachets a day. If administered regularly, the frequency of bowel movements tends to

be one movement per day. In children, treatment should not exceed 3 months due to a lack of clinical data for treatment

lasting longer than 3 months. Treatment-induced restoration of bowel movements will be maintained by lifestyle and

dietary measures.

Method of administration

Oral use.

1 to 2 sachets per day, preferably taken as a single dose in the morning. The content of each sachet should be dissolved

in a glass of water just before use. The effect of Macrosoft becomes apparent within 24 to 48 hours after its

administration.

The reconstituted solution is colourless & clear.

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1

Severe inflammatory bowel disease (such as ulcerative colitis, Crohn’s disease) or toxic megacolon

Digestive perforation or risk of digestive perforation

Ileus or suspicion of intestinal obstruction or symptomatic stenosis

Painful abdominal syndromes of indeterminate cause

4.4 Special warnings and precautions for use

As with all laxatives, an organic disorder should have been ruled out before initiation of treatment.

Without investigating the cause of constipation, Macrosoft should not be taken on a continuous daily basis for an

extended period of time. The patient is instructed to seek medical advice in case of persistent abdominal pain.

In case of diarrhoea, caution should be exercised in patients who are prone to a disturbance of water or electrolyte

balance (e.g. elderly, patients with impaired hepatic or renal function or patients taking diuretics) and electrolyte

control should be considered.

Allergic conditions (such as anaphylactic shock, anaphylactic reaction, angioedema, urticaria, rash and

hypersensitivity) have been reported with drugs containing macrogol (polyethylene glycol).

Macrosoft contains sorbitol. Patients with the rare hereditary condition of fructose intolerance should not take this

medicine.

4.5 Interaction with other medicinal products and other forms of interaction

Macrogol 4000 increases the osmotic pressure in the gut, and thus might modify the intestinal absorption of drugs

concomitantly administered.

4.6 Fertility, pregnancy and lactation

Pregnancy

There are no adequate and well-controlled studies in pregnant women. Non-clinical studies are insufficient with respect

to reproductive toxicity. No effects during pregnancy are anticipated, since systemic exposure to macrogol 4000 is

negligible. Macrosoft can be used during pregnancy

Breast-feeding

There are no data on the excretion of macrogol 4000 in breast milk. No effects on the breastfed newborn/infant are

anticipated since the systemic exposure of the breast-feeding woman to macrogol 4000 is negligible (see section 5.2).

Macrosoft can be used during breast-feeding

Fertility

No studies on the effect on human fertility have been conducted. No effects on fertility are anticipated, since systemic

exposure to macrogol 4000 is negligible. (see section 5.2).

4.7 Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed.

5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Drugs for constipation, osmotically acting laxatives, ATC code: A06AD15

Mechanism of action

Macrogol 4000 softens the stool by retaining water molecules. Thereby it increases the stool volume, which triggers

colon motility via neuromuscular pathways. The physiological consequence is an improved propulsive colonic

transportation of the softened stools which facilitates defaecation.

Pharmacodynamic effects

Different doses of macrogol are shown to have different effects on intestinal function. In normal volunteers, low doses

increase stool weight without modifying oro-anal transit time. In constipated patients, low doses decrease stool

consistency, increase stool frequency, and facilitate stool evacuation without modifying stool weight and colonic transit

time. Bloating produced by the administration of macrogol is usually due to intestinal distention by water binding.

Clinical efficacy

Adult population:

A multicentre, double-blind, randomised, parallel-group 4 weeks study involving 266 patients with idiopathic chronic

constipation compared the efficacy and tolerability of two different doses of macrogol 4000 (10 or 20 g) with two

different doses of macrogol 3350 plus electrolytes (5.9 or 11.8 g). The results showed that both doses of macrogol 4000

and macrogol 3350 were effective in treating the symptoms of constipation and were well tolerated. The treatment

improved stool consistency in all groups from baseline, with the percentage of patients with normal stool consistency

increasing during the course of the study. During the course of the study straining at stool, rectal evacuation, abdominal

bloatedness and abdominal pain were all significantly improved. Similarly, the quality of life was significantly

improved compared with baseline. Most patients (

67.3%) had their first stool within 1 day of starting treatment.

Paediatric population:

Macrogol 4000 was used to treat constipation in a 3-month multicentre non-comparative study with 96 children aged

from 6 months - 15 years. The study confirmed the efficacy and wide safety margin of PEG 4000 also in diet-resistant

constipation. More than 90% of children recovered normal bowel habits, with an improvement in stool frequency,

consistency, appetite, fecal soiling, fecal mass in the rectum, and abdominal pain related to constipation. For children

aged 8 years to 15 years the study found a median effective dose comparable to the daily dosage for the treatment of

constipation in adults (i.e., 10–20 g). A pooled Cochrane analysis suggested that macrogol preparations might be

superior to placebo, lactulose, and milk of magnesia in terms of stool amounts generated for the treatment of childhood

constipation.

5.2 Pharmacokinetic properties

Absorption

Macrogol 4000 is only minimally absorbed, i.e. 0.05%, from the intestine of healthy subjects following an oral

administration of 2 g.

Metabolism

Like other polyethylene glycols with molecular masses exceeding 3000 Da, macrogol 4000 does not undergo any

intestinal enzymatic degradation or bacterial metabolism.

Elimination

Macrogol 4000 is eliminated in the faeces with very high recovery rates ranging between 93% and 100%. Urinary

excretion of macrogols occurs through passive glomerular filtration. Macrogol 4000 is excreted unchanged in urine

with mean urinary recovery ranging from 0.05% to 0.46%.

5.3 Preclinical safety data

Toxicological studies in different species of animals did not reveal any signs of systemic or local gastrointestinal

toxicity of macrogol 4000. Macrogol 4000 had no teratogenic, mutagenic, nor carcinogenic effect. No studies on
