Pharmacology

πŸ”¬

Mechanism of Action

Prucalopride is a selective, high-affinity serotonin-4 (5-HT4) receptor agonist. By activating 5-HT4 receptors in the gastrointestinal tract, it stimulates colonic motility, leading to increased bowel movements and improved stool consistency. It promotes propulsive contractions, which are essential for the passage of stool.

Overdose Information

Overdose Symptoms:

  • Headache
  • Nausea
  • Diarrhea
  • Abdominal pain

What to Do:

In case of overdose, contact a poison control center immediately. The national poison control center number is 1-800-222-1222. Treatment should be supportive and symptomatic. There is no specific antidote.

Drug Interactions

🟑

Moderate Interactions

  • Drugs that prolong QT interval (theoretical risk, monitor ECG if co-administered)
  • Other prokinetic agents (e.g., metoclopramide, domperidone) - potential for additive effects
⚠️

Confidence Interactions

Monitoring

πŸ”¬

Baseline Monitoring

Diagnosis of Chronic Idiopathic Constipation (CIC)

Rationale: Ensure appropriate indication for treatment.

Timing: Prior to initiation

Renal function (e.g., CrCl)

Rationale: To determine appropriate dosing, especially in patients with severe renal impairment.

Timing: Prior to initiation

πŸ“Š

Routine Monitoring

Bowel movement frequency and consistency

Frequency: Daily/Weekly

Target: Increased frequency, improved consistency (e.g., Bristol Stool Scale 3-4)

Action Threshold: Lack of improvement after 4 weeks, or worsening symptoms

Abdominal pain, bloating, nausea

Frequency: Daily/Weekly

Target: Resolution or reduction of symptoms

Action Threshold: Persistent or worsening symptoms, especially severe abdominal pain

πŸ‘οΈ

Symptom Monitoring

  • Frequency of bowel movements
  • Stool consistency (Bristol Stool Scale)
  • Straining during defecation
  • Feeling of incomplete evacuation
  • Abdominal pain
  • Abdominal bloating
  • Nausea
  • Headache
  • Dizziness
  • Mood changes (e.g., depression, anxiety, suicidal thoughts)

Special Patient Groups

🀰

Pregnancy

Prucalopride may cause fetal harm based on animal studies. Use during pregnancy should only be considered if the potential benefit justifies the potential risk to the fetus. There are no adequate and well-controlled studies in pregnant women.

Trimester-Specific Risks:

First Trimester: Animal studies showed adverse developmental effects (e.g., skeletal abnormalities, reduced fetal weight) at doses higher than human therapeutic doses.
Second Trimester: Similar considerations as first trimester.
Third Trimester: Similar considerations as first trimester.
🀱

Lactation

It is unknown if prucalopride is excreted in human milk. Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for prucalopride and any potential adverse effects on the breastfed infant from prucalopride or from the underlying maternal condition. Based on its pharmacokinetic properties (low protein binding, high bioavailability, renal excretion), transfer into milk is possible but likely low. Monitor breastfed infants for diarrhea.

Infant Risk: Low risk (L3 - no human data, but properties suggest low risk; monitor for diarrhea)
πŸ‘Ά

Pediatric Use

Safety and effectiveness have not been established in pediatric patients less than 18 years of age. Not recommended for this population.

πŸ‘΄

Geriatric Use

No specific dose adjustment is required based on age alone. However, elderly patients are more likely to have decreased renal function, which necessitates dose adjustment for severe renal impairment. Monitor for adverse effects as elderly patients may be more sensitive.

Clinical Information

πŸ’Ž

Clinical Pearls

  • Prucalopride is a good option for chronic idiopathic constipation (CIC) when osmotic laxatives or fiber supplements have been insufficient.
  • It is a highly selective 5-HT4 agonist, which contributes to its efficacy and potentially lower side effect profile compared to less selective agents.
  • Patients should be advised that while some may experience a bowel movement within 24 hours, the full therapeutic benefit for CIC may take several days or weeks.
  • Emphasize the importance of adequate fluid intake and dietary fiber alongside medication for optimal results.
  • Counsel patients on potential side effects like headache, nausea, and abdominal pain, which are often transient and resolve with continued use.
  • Monitor for new or worsening psychiatric symptoms, including depression and suicidal ideation, as these have been reported in clinical trials.

Alternative Therapies

  • Polyethylene glycol (PEG)
  • Lactulose
  • Lubiprostone (Amitiza)
  • Linaclotide (Linzess)

  • Fiber supplements (e.g., psyllium, methylcellulose)
  • Stool softeners (e.g., docusate)
