pentamidine and Keratitis, Acanthamoeba

pentamidine has been researched along with Keratitis, Acanthamoeba in 8 studies

Pentamidine: Antiprotozoal agent effective in trypanosomiasis, leishmaniasis, and some fungal infections; used in treatment of PNEUMOCYSTIS pneumonia in HIV-infected patients. It may cause diabetes mellitus, central nervous system damage, and other toxic effects.
pentamidine : A diether consisting of pentane-1,5-diol in which both hydroxyl hydrogens have been replaced by 4-amidinophenyl groups. A trypanocidal drug that is used for treatment of cutaneous leishmaniasis and Chagas disease.
