Miltefosine is also a good option in patients who are resistant to pentavalent antimony or exhibit cross-resistance to amphotericin B.6 The terminal half-life of miltefosine is long which ranges between 150 and 200 hours and about four half-lives (25-33 days) are needed to reach more than 90% of the peak levels, thereby a subtherapeutic level of miltefosine may remain for some weeks after a 4 week course.8 This feature might encourage the emergence of resistance but it can be prevented by ensuring good compliance and adequate dosing for adequate duration or by using combination therapies.8
