WEINBERG, Adriana et al. Aerosolised pentamidine for Pneumocystis carinii pneumonia in patients with acquired immunodeficiency syndrome. Rev. Inst. Med. trop. S. Paulo [online]. 1990, vol.32, n.4, pp. 289-295. ISSN 0036-4665. http://dx.doi.org/10.1590/S0036-46651990000400009.
The goal of this study was to evaluate inhaled pentamidine for the treatment of patients with mild and moderate Pneumocystis carinii pneumonitis. Eight adults with AIDS and pneumocystis pneumonia (4 with a first episode and 4 with a repeat pneumocystosis) received daily inhalations of aerosol pentamidine isethionate for 21 days. Six patients were treated with doses of 300 mg of pentamidine and the remaining 2 received 600 mg every day. In the 300 mg treatment group, 2 individuals showed discrete and transient neutropenia. However, both subjects that received 600 mg of aerosol pentamidine daily developed leukopenia. One of them had major toxicity (overall severe intolerance of 12.5%) that required drug discontinuation and did not allow any analysis of the treatment efficacy. Of the 7 evaluable patients, 6 (88%) completed the treatment successfuly. One subject of the 300 mg regimen experienced an early recurrence. In conclusion, inhaled pentamidine is an effective treatment for mild and moderate cases of P. carinii pneumonia. It is less toxic than standard anti-pneumocystis therapy and is suitable for outpatient use.
