Nifedipine and esophageal dysfunction in progressive systemic sclerosis. A controlled manometric study.

Area of Science:

• Gastroenterology
• Rheumatology
• Pharmacology

Background:

• Progressive systemic sclerosis often involves esophageal dysfunction.
• Gastrointestinal complications are common in systemic sclerosis.

Purpose of the Study:

• To assess the impact of nifedipine on esophageal motility in patients with progressive systemic sclerosis.
• To determine if nifedipine affects lower esophageal sphincter pressure and gastroesophageal reflux.

Main Methods:

• Double-blind, randomized, crossover, placebo-controlled manometric study.
• 15 patients with progressive systemic sclerosis were included.
• Esophageal manometry was used to measure sphincter pressure.

Main Results:

• Nifedipine significantly decreased lower esophageal sphincter pressure.
• Reduced sphincter pressure may lead to gastroesophageal reflux.
• The findings suggest potential adverse effects of nifedipine.

Conclusions:

• Nifedipine may have detrimental effects on patients with progressive systemic sclerosis.
• The drug's impact on esophageal function warrants further investigation.
• Careful consideration of nifedipine use in this patient population is advised.
