The present invention relates to the field of therapy and drug delivery. More specifically, therapeutic methods and pharmaceutical compositions for treating disorders of blood-tissue barrier-protected organs that harbor substantial populations of postmittal neurons, such as organs derived from the neural tube, including the central nervous system and the eye. The disclosed methods and compositions involve topical administration of an effector component that targets intracellular biological targets to such organs, in combination with a saponin component that enhances the effective uptake of the effector component into cells and / or enhances the effective delivery of the effector component within cells where the biological target is present. For example, the effector component may be an oligonucleotide therapeutic that targets gene products associated with CNS and / or ocular disorders. Due to the cellular uptake stimulating and / or endosomal escape enhancing effects of the saponin component, the neuropharmaceuticals and ophthalmic compositions presented herein for topical administration to the CNS and / or eye, respectively, can be formulated with lower concentrations of the effector component and / or lower volumes, which provides safety benefits to neurons and patient comfort.
