Neostigmine: an alternative treatment for constipation.

Constipation is a common complication of amyotrophic lateral sclerosis (ALS), especially as the disease progresses. While ALS patients may experience disturbed gastrointestinal motility due to the nature of the disease and decreased physical activity, the constipation is not usually caused by mechanical obstruction. Acute colonic pseudo-obstruction (ACPO) is a syndrome characterized by massive dilation of the colon without mechanical obstruction. Recent studies have shown neostigmine may be an effective treatment for ACPO. Through a case study, the author discusses the use of neostigmine and its nursing implications on a patient with ALS.
