Single-dose liposomal amphotericin B for visceral leishmaniasis
Correspondence
Single-dose liposomal amphotericin B for visceral leishmaniasis Dinesh Mondal and colleagues (January, p e51)1 investigated the safety and efficacy of single-dose liposomal amphotericin B for treatment of visceral leishmaniasis (also known as kala azar) in Bangladesh. The successful administration of single-dose liposomal amphotericin B at a primary health centre is heartening. In a linked Comment, Prabhat Kumar Sinha and Sujit Bhattacharya2 discussed adverse events reported in the study. Concerns about potential risks of adverse drug reactions and resistance prompted WHO to initiate pharmacovigilance for miltefosine,3 another drug used to treat leishmaniasis, and develop an educational manual for patients and health workers.4 Pharmacovigilance and reporting of adverse drug reactions, especially at primary health centres, remain difficult. Efforts are needed for post-marketing surveillance of single-dose liposomal amphotericin B for cost, benefit, and safety in real life. Sinha and Bhattacharya also refer to

the high cost of treatment with liposomal amphotericin B (Ambisome, Gilead, USA). An alternative low-cost formulation, developed in academic institutions in India with funding from the Indian Department of Biotechnology,5 has been tested for leishmaniasis6 and has been commercialised as Fungisome (Lifecare, India) by a scientist entrepreneur, and could be provided a much lower price than that of Ambisome. Post-marketing surveillance has been done with results similar to those of pre-marketing phase 1–3 studies.7 Clinical trials funded by the Indian Government of single doses of this formulation are underway, and have shown promising initial results for safety and efficacy. We hope that this drug will further lower the cost of treatment, making therapy affordable to patients with the greatest need. I declare that I have no competing interests. Copyright © Kshirsagar.
