1.6 LAXATIVES

1.6 Laxatives
 
Dietary advice is important. Before prescribing laxatives it is also important to be sure the patient is constipated and that it is 
not secondary to an underlying undiagnosed complaint. Use only if really necessary - not for long term use. 
 
         1.6.1 Bulk-forming laxatives
            May be required when fibre cannot be increased in the diet. Of value in those with small hard stools, need an adequate 
            fluid intake and may take a few days for full effect to develop.

            AMBER     Normacol Plus® (post gastrointestinal surgery)   
 
         1.6.2 Stimulant laxatives
            Increase intestinal motility, often cause abdominal cramp, should not be used in intestinal obstruction.

            GREEN      Arachis oil enema
 
         1.6.4 Osmotic laxatives
            Retain fluid in the bowel and change the pattern of water distribution in the faeces. They commonly cause bloating, 
            flatulence and cramping and are unpalatable for some patients. They must be taken regularly for up to three days before 
            an effect is seen, making them unsuitable for rapid relief of constipation or for ‘as required’ dosing.

           NICE TA345 Naloxegol (Moventig®is recommended, within its marketing authorisation, as an option for treating opioid  
           induced constipation in adults whose constipation has not adequately responded to laxatives.
           An inadequate response is defined as opioid‑induced constipation symptoms of at least moderate severity in at least 1 of
           the 4 stool symptom domains (that is, incomplete bowel movement, hard stools, straining or false alarms) while taking at 
           least 1 laxative class for at least 4 days during the prior 2 weeks. NICE TAG345.

         1.6.7 5HT4 receptor agonists and guanylate cyclase-C receptor agonists
            Prucalopride (Resolor®) for the treatment of chronic constipation in women (NICE TA211)
 
                   1.    Prucalopride is recommended as an option for the treatment of chronic constipation only in women for whom 
                          treatment with at least two laxatives from different classes, at the highest tolerated recommended doses for at least 
                          6 months, has failed to provide adequate relief and in whom invasive treatment for constipation is being considered.
                   2.    If treatment with prucalopride is not effective after 4 weeks, the woman should be re-examined and the benefit of
                          continuing treatment reconsidered.
                   3.    Prucalopride should only be prescribed by a clinician with experience of treating chronic constipation, who has 
                          carefully reviewed the woman’s previous courses of laxative treatments specified in point 1.

            Linaclotide (Constella®) treatment of moderate to severe irritable bowel syndrome with constipation in adults who 
            have not responded to conventional treatment. 
            Linaclotide can be considered as an option (specialist initiation only) for the treatment of persistent constipation in adults 
            with IBS who have not responded to conventional treatment based on suggested treatment pathway:
                   1.    Follow irritable bowel syndrome in adults NICE CG61 (2008) and manage constipation  with a range of osmotic and
                          stimulant laxatives with the long-term use of soluble fibre 
                   2.    Where antispasmodics and laxatives are ineffective for pain relief, NICE suggests the use of tricyclic   
                          antidepressants (unlicensed use)
                   3.    Assess patient at 4 weeks (in secondary care) and if no improvement discontinue use
                   4.    If continued beyond 4 weeks, re-assess at 6 months for continued benefit
