Pentamidine isethionate is a crucial drug for treating Pneumocystis carinii pneumonia (PCP) in AIDS patients. While aerosolized pentamidine shows promise for PCP prevention due to lower toxicity, its treatment efficacy requires further research.

Area of Science:

  • Pharmacology and Clinical Medicine
  • Infectious Diseases
  • Pulmonology

Background:

  • The rise of Acquired Immunodeficiency Syndrome (AIDS) has increased the importance of pentamidine isethionate.
  • Pentamidine isethionate is used for treating Pneumocystis carinii pneumonia (PCP).

Purpose of the Study:

  • To review the pharmacology, toxicity, and clinical use of pentamidine isethionate.
  • To evaluate aerosolized pentamidine for PCP therapy and prevention.

Main Methods:

  • Review of existing literature on pentamidine isethionate.
  • Analysis of clinical data regarding parenteral and aerosolized administration.

Main Results:

  • Conflicting data exist on pentamidine's efficacy versus cotrimoxazole for PCP treatment in AIDS patients.

  • Parenteral pentamidine has significant toxicities: hypoglycemia (27%) and nephrotoxicity (25%).
  • Aerosolized pentamidine demonstrates convenience and reduced toxicity, suggesting potential for PCP prevention.

    • Conclusions:

    • Pentamidine isethionate is often considered second-line therapy for PCP due to toxicity and cost.
    • Aerosolized pentamidine may become the preferred method for PCP prevention in high-risk individuals.
    • Further data are needed to establish the role of aerosolized pentamidine in PCP treatment.
