A comparative study of two dicyclomine preparations in functional bowel disorders

Area of Science:

• Gastroenterology
• Clinical Pharmacology

Background:

• Gastrointestinal spasms are common conditions requiring effective and safe treatment.
• Dicyclomine hydrochloride is a widely used antispasmodic agent.
• Different formulations of dicyclomine may offer varying therapeutic profiles.

Purpose of the Study:

• To compare the efficacy and safety of sustained-release 40 mg dicyclomine hydrochloride tablets (Merbentyl Dospan) against plain 20 mg dicyclomine hydrochloride tablets (Merbentyl).
• To evaluate the therapeutic equivalence of two dicyclomine hydrochloride formulations in patients with gastrointestinal spasms.

Main Methods:

• A double-blind crossover study design was employed.
• Patients with gastrointestinal spasm-related maladies participated in the trial.
• Participants received both sustained-release 40 mg and plain 20 mg dicyclomine hydrochloride tablets in a randomized sequence.

Main Results:

• Both dicyclomine hydrochloride formulations demonstrated comparable efficacy in managing gastrointestinal spasms.
• The incidence of side effects was low and similar between the sustained-release and plain tablet groups.
• No significant differences in therapeutic outcomes or adverse events were observed.

Conclusions:

• Sustained-release 40 mg dicyclomine hydrochloride (Merbentyl Dospan) and plain 20 mg dicyclomine hydrochloride (Merbentyl) are therapeutically equivalent.
• Both formulations provide effective relief from gastrointestinal spasms with a low risk of adverse effects.
• The choice between formulations can be based on patient convenience or physician preference.
