Why LPV/r pellets are recommended for young children
In 2015, the United States Food and Drug Administration tentatively approved a new formulation of lopinavir/ritonavir (LPV/r), a pediatric antiretroviral: See Latest Research.
- The pellets are approved only for use in children 3 months or older and weighing 5 kilograms or more. See Fact Sheet on Lopinavir and Ritonavir (LPV/r) Pellets [PDF, 713KB].
- Caregivers should give infants and young children living with HIV LPV/r pellets two times each day. See Weight Dosing Tool.
- For younger children, the pellets are easier to swallow than tablets. Both pellets and tablets must be swallowed fully intact. They cannot be stirred, broken, crushed, chewed, or dissolved.
- The pellets' taste can be masked by food or breast milk, unlike the LPV/r solution.
- The pellets do not require refrigeration unlike the LPV/r solution.
