Laxatives: Gastroparesis Treatment?

Gastroparesis is a gastric motility disorder characterised by the delayed emptying of stomach contents without any mechanical obstruction. It is caused by diabetes complications or can be idiopathic. The condition causes nausea, vomiting, fullness after eating, early satiety, abdominal pain and bloating.

Laxatives are not mentioned as a treatment for gastroparesis. However, constipation is a symptom of the condition, and osmotic laxatives have been shown to improve dyspeptic symptoms and gastric emptying delay.

Prucalopride may be an effective treatment for gastroparesis

Prucalopride is a third-generation, highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist. It is used to treat chronic constipation and is considered a potential treatment for gastroparesis. Prucalopride stimulates colonic transit and is the underlying principle of action for chronic constipation. It has been shown to improve gastric transit in canine models and healthy subjects, as well as in patients with chronic constipation.

Prucalopride has been studied in a small number of small, randomised, placebo-controlled crossover studies in patients with predominantly female idiopathic or diabetic gastroparesis. These studies have shown that prucalopride can improve gastric emptying and stool frequency and reduce the severity of symptoms such as bloating, nausea, and fullness. However, it does not appear to improve gastroparesis or diet-related symptoms.

Prucalopride is generally well-tolerated and has a favourable safety profile. The most common side effects are abdominal pain, diarrhoea, nausea, and headache, which usually occur within the first 24 hours of treatment and are typically mild to moderate and self-limiting. Prucalopride does not affect the P-glycoprotein or cytochrome P450 functions and has a low risk of clinically significant interactions with other drugs. It is also excreted mainly in the urine and is not significantly metabolised in the body.

Prucalopride is currently not recommended as a first-line treatment for gastroparesis due to its relatively high price. However, it may be considered for patients who have not obtained relief from laxatives or other conventional treatments. The recommended dosage is 2 mg once daily, although a lower starting dose may be preferable for gastroparesis, especially in diabetic patients. The therapeutic scheme may also be adjusted to determine the minimum effective dose for each patient.

Prucalopride is a prokinetic agent that improves gastrointestinal motility

Prucalopride is a highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist that stimulates colonic motility by modulating acetylcholine release from cholinergic neurons and, in turn, colonic longitudinal muscular contraction and circular muscle relaxation. It is a prokinetic agent that improves gastrointestinal motility and is approved for the treatment of chronic constipation.

Prucalopride has been shown to stimulate gut motility in vitro and in vivo and is currently FDA-approved for the management of chronic constipation. It has the potential to treat symptoms of gastroparesis and delayed gastric emptying. A recent controlled cross-over trial showed improvements of symptoms and gastric emptying in patients with idiopathic gastroparesis who received prucalopride over a period of 4 weeks.

Prucalopride is a safe and effective treatment to reduce post-operative ileus and systemic inflammation without affecting post-operative complications in patients undergoing elective gastrointestinal surgery. It has also been shown to reduce symptoms in patients with chronic intestinal pseudo-obstruction.

Prucalopride is not approved for the treatment of opioid-induced constipation.

Prucalopride is a second-line treatment for chronic constipation

Prucalopride is a highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist, which acts as a prokinetic drug. It is a third-generation drug, and is used to treat chronic constipation. It is recommended by the National Institute for Health Care Excellence (NICE) for chronic constipation in women. It is also the only agent recommended by NICE for this purpose.

Prucalopride is a safe and effective treatment for chronic constipation, especially in patients who have failed basic laxative therapy. It is also effective in treating constipation in patients with chronic opioid use and spinal cord injury. It has been proven to be safe for use in elderly patients, including those with a history of cardiovascular disease. However, it should be used with caution in patients with impaired liver and renal function.

Prucalopride has a rapid onset of action and the improvement in symptoms is maintained for at least 12 weeks. It is generally well-tolerated, with mild or moderate side effects that occur mainly during the first few days of treatment. The most common side effects are headaches and nausea. It is recommended to start with a 1 or 2 mg dose once daily, and increase the dose if needed.

Prucalopride is contraindicated for dialysis patients

Prucalopride is a highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist. It is a prokinetic agent that improves gastrointestinal motility by increasing the frequency or strength of intestinal contractions without disrupting their rhythm. It is used to treat chronic constipation by targeting the serotonin (5-HT4) receptors in the digestive tract to stimulate muscle movement (motility). It is also used to treat gastroparesis, a motility disorder affecting 4% of Canadians, which occurs when food does not move from the stomach into the intestine as quickly as it should, usually due to damage to, or impaired function of, the nerves connecting the brainstem to the gastrointestinal tract (vagus nerve).

Prucalopride is cleared from the body through urine. It is contraindicated for dialysis patients as it is excreted unchanged in urine and about 6% in faeces. It is also contraindicated for individuals with a history of intestinal obstruction, drug sensitization, toxic megacolon, or if pregnant or lactating.

Prucalopride may not be effective in treating gastroparesis in the long term

Prucalopride is a highly selective 5-hydroxytryptamine 4 (5-HT4) receptor agonist. It is used to treat chronic constipation by stimulating colonic transit. It has also been studied for its potential to treat gastroparesis, a condition characterised by delayed gastric emptying.

Prucalopride has been shown to be effective and safe for treating chronic constipation. It is generally well-tolerated, with the most common adverse effects being nausea, headache, abdominal pain, and diarrhoea. However, it is not recommended for use during pregnancy or lactation.

Prucalopride has also been studied for its potential to treat gastroparesis. Two small randomised placebo-controlled crossover pilot trials have shown that prucalopride can improve gastric emptying and reduce the severity of gastroparesis symptoms. However, one of the studies found that prucalopride did not improve symptoms in patients with diabetic gastroparesis. More research is needed to determine the effectiveness of prucalopride in treating gastroparesis, especially in patients with diabetic gastroparesis.
