Neglected populations: safeguarding the health of street-involved children in Ghana.

abstract：:Midazolam (MDZ) is a benzodiazepine commonly administered in preanesthesia of children by oral or by sublingual routes. To mask its bitter taste and enhance its aqueous solubility, we already developed a 0.2% (w/v) MDZ oral solution containing γ-cyclodextrin (γ-CD), which proves to be better accepted by children in pe...
