The choice of nebuliser and delivery system is If nebulisers are to be used within the hospital dictated by the need to deposit pentamidine then nebulisation should be carried out in a in the alveoli and to avoid deposition in the room separate from the main ward area, ideally oropharynx, trachea, and major bronchi. ...

Trimethoprim-sulfamethoxazole and parenteral pentamidine isethionate are effective in 60 to 80 per cent of AIDS patients with pneumocystis pneumonia. Adverse reactions are frequent with both agents, but because the adverse reactions are less severe with trimethoprim-sulfamethoxazole, this agent is the drug of choice for patients who are not known to be intolerant of it. The recommended duration...

Aromatic dicationic compounds, such as pentamidine, have potent antimicrobial activities. Clinical use of these compounds has been restricted, however, by their toxicity and limited oral activity. A novel approach, using amidoxime derivatives as prodrugs, has recently been proposed to overcome these limitations. Although results were presented for amidoxime derivatives of only one diamidine, pe...

African trypanosomes cause sleeping sickness in humans, a disease that is typically fatal without chemotherapy. Unfortunately, drug resistance is common and melarsoprol-resistant trypanosomes often display cross-resistance to pentamidine. Although melarsoprol/pentamidine cross-resistance (MPXR) has been an area of intense interest for several decades, our understanding of the underlying mechani...

Leishmania aethiopica is the etiological agent of cutaneous leishmaniasis (CL) in Ethiopia and can cause severe and complicated cases such as diffuse CL (DCL), mucocutaneous leishmaniasis or extensive CL, requiring systemic treatment. Despite the substantial burden, evidence-based treatment guidelines are lacking. We conducted a systematic review of clinical studies reporting on treatment outco...

Bisbenzamidines, such as pentamidine isethionate, are aromatic dicationic compounds that are active against Pneumocystis and other microbes but are oftentimes toxic to the host. To identify potential anti-Pneumocystis agents, we synthesized bisbenzamidine derivatives in which the parent compound pentamidine was modified by a 1,4-piperazinediyl, alkanediamide, or 1,3-phenylenediamide moiety as t...

The amino analogues of pentamidine with a polymethylene (n = 3 - 6) chain and their chlorambucil derivatives were synthesized. The obtained compounds revealed cytotoxic effect on MCF-7 human breast cancer cell line (IC50 = 22 - 95 +/- 2 pM), mainly by the induction of apoptosis. The topoisomerase I/II inhibition assay and the ethidium displacement assay with the use of pBR322 plasmid DNA were u...

Abstract INTRODUCTION Management of diffuse gliomas often includes radiation plus concomitant and adjuvant temozolomide. Hematologic toxicities are common from this therapy. Patients frequently receive prophylaxis against pneumocystis jirovecii pneumonia (PJP) during chemoradiation; however, some PJP drugs have the potential to independently cause myelosuppression which could exacerbate hematol...
