The LDN (low-dose naltrexone) vs ARV (anti-retroviral drugs) Effectiveness Study in Mali sponsored by The Ojai Foundation in California-USA is a clinical research study endorsed and approved by the Malian Government. Naltrexone hydrochloride is a generic, FDA-approved since 1998 drug, an opioid antagonist that has clinically shown immune enhancing/modulating qualities in very low dosage and may offer an alternative to ARV drugs that is effective, non-toxic, easily available, inexpensive, with simple once-daily at bedtime administration. LDN capsules must be created by compounding pharmacists to get these ultra-small doses. Due to toxicity of current ARV drugs and need for special medical management young HIV infected children are largely neglected particularly in developing countries; LDN can also be made available in a transdermal cream for infants and children who are HIV infected.
