Fatal paralytic ileus complicating phenothiazine therapy

Area of Science:

• Pharmacology
• Gastroenterology
• Clinical Medicine

Background:

• Phenothiazines and antiparkinsonian agents are commonly prescribed medications.
• Paralytic ileus and peritonitis are serious gastrointestinal complications.
• The co-occurrence of these conditions with the specified drug classes is rarely emphasized.

Purpose of the Study:

• To describe a case of fatal paralytic ileus with peritonitis in a patient using phenothiazines and an antiparkinsonian agent.
• To highlight the underreported nature of this adverse drug reaction.
• To emphasize the importance of clinical awareness for timely diagnosis and management.

Main Methods:

• Case report detailing a patient's clinical presentation, treatment, and outcome.
• Literature review to assess the frequency and emphasis of this complication.

Main Results:

• A patient developed fatal paralytic ileus with peritonitis while on phenothiazine and antiparkinsonian therapy.
• Sporadic reports exist, but this complication is not widely recognized in the literature.

Conclusions:

• Clinicians must maintain a high index of suspicion for paralytic ileus and peritonitis in patients on these medications.
• Prompt recognition and intervention are essential for potentially improving patient outcomes.
• Further research may be needed to elucidate the exact mechanism and incidence.
