The relative systemic availability of ivermectin after administration as capsule, tablet, and oral solution.

Administration of 12-mg doses of ivermectin (H2B1a) to 12 healthy volunteers in the form of tablets, capsules, and alcoholic oral solution showed the solution to have approximately twice the systemic availability as either of the solid forms, as evidenced both by the maximum concentrations of drug attained in plasma and by the corresponding areas under the plasma concentration vs time curves. However, the two solid formulations showed similar systemic availability.
