Pharmacology

πŸ”¬

Mechanism of Action

Prucalopride is a selective, high-affinity serotonin-4 (5-HT4) receptor agonist. By activating 5-HT4 receptors, it stimulates colonic motility, leading to increased bowel movements and improved stool consistency. It enhances propulsive colonic motility, which is often impaired in chronic constipation.

Overdose Information

Overdose Symptoms:

  • Headache
  • Nausea
  • Vomiting
  • Diarrhea
  • Abdominal pain

What to Do:

In case of overdose, contact a poison control center (1-800-222-1222) or seek emergency medical attention. Treatment is supportive.

Drug Interactions

🟑

Moderate Interactions

  • Drugs that prolong QT interval (theoretical risk, though prucalopride itself has minimal QT effect at therapeutic doses)
  • P-glycoprotein inhibitors (e.g., cyclosporine, quinidine, verapamil, amiodarone, ritonavir, clarithromycin) - potential for increased prucalopride exposure, but not considered clinically significant based on studies.

Monitoring

πŸ”¬

Baseline Monitoring

Renal function (Creatinine Clearance)

Rationale: To determine appropriate dosing, especially for patients with impaired renal function.

Timing: Prior to initiation of therapy

πŸ“Š

Routine Monitoring

Efficacy (Bowel movement frequency, stool consistency)

Frequency: Ongoing, as clinically indicated

Target: Individualized improvement in constipation symptoms

Action Threshold: Lack of improvement or worsening symptoms may warrant re-evaluation

Tolerability (Adverse effects)

Frequency: Ongoing, especially during initial weeks of therapy

Target: Absence or mild, transient side effects

Action Threshold: Persistent or severe abdominal pain, nausea, diarrhea, headache, or other intolerable side effects

πŸ‘οΈ

Symptom Monitoring

  • Abdominal pain
  • Nausea
  • Diarrhea
  • Headache
  • Dizziness
  • Fatigue
  • Depression or suicidal thoughts (rare, but reported in clinical trials)

Special Patient Groups

🀰

Pregnancy

Limited human data on prucalopride use in pregnant women are insufficient to inform a drug-associated risk for major birth defects or miscarriage. Animal studies have shown adverse developmental outcomes. Use only if the potential benefit justifies the potential risk to the fetus.

Trimester-Specific Risks:

First Trimester: Potential risk based on animal data; human data limited.
Second Trimester: Potential risk based on animal data; human data limited.
Third Trimester: Potential risk based on animal data; human data limited.
🀱

Lactation

Limited human data suggest that prucalopride is excreted in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Motegrity and any potential adverse effects on the breastfed infant from Motegrity or from the underlying maternal condition.

Infant Risk: L3 (Moderate risk). Monitor breastfed infants for diarrhea.
πŸ‘Ά

Pediatric Use

Safety and effectiveness in pediatric patients (under 18 years of age) have not been established for chronic idiopathic constipation.

πŸ‘΄

Geriatric Use

No dose adjustment is required based on age alone. However, elderly patients are more likely to have decreased renal function, so dose adjustment should be based on creatinine clearance (CrCl) if impaired.

Clinical Information

πŸ’Ž

Clinical Pearls

  • Motegrity is intended for chronic use and is not for acute constipation relief.
  • Patients should be advised that it may take several days to achieve a full therapeutic effect.
  • Common side effects such as headache, nausea, abdominal pain, and diarrhea are usually transient and tend to decrease with continued use.
  • Ensure patients maintain adequate hydration while on therapy.
  • Assess renal function prior to initiating therapy and adjust dose accordingly for severe renal impairment.
πŸ”„

Alternative Therapies

  • Linaclotide (Linzess)
  • Lubiprostone (Amitiza)
  • Plecanatide (Trulance)
  • Polyethylene Glycol (PEG) 3350 (e.g., MiraLAX)
  • Fiber supplements (e.g., psyllium, methylcellulose)
  • Osmotic laxatives (e.g., magnesium hydroxide, lactulose)
  • Stimulant laxatives (e.g., bisacodyl, senna - for short-term use)
