METHODS AND SYSTEMS FOR COATING A MICRONEEDLE WITH A DOSAGE OF A BIOLOGICALLY ACTIVE COMPOUND

摘要

Methodologies and systems are disclosed for coating one or more microneedles, particularly in a microneedle array, for administering a predetermined dosage of biologically active compound through the skin to a recipient. The microneedles of the array are each immersed into at least one reservoir of a fluid liquid formulation of the biologically active compound wherein the at least one reservoir receives a metered predetermined amount of the formulation that corresponds to the dosage to be coated on each microneedle. The microneedles are immersed into the at least one reservoir one or more times to consume the entire amount of formulation in the at least one reservoir such the consumed amount forms the coating comprising one or more layers comprising the predetermined dose on each microneedle. Various embodiments are disclosed for immersing the microneedles one needle at a time, one or more times into the reservoir, or in an array into corresponding reservoirs in one or more repetitive immersions. The reservoirs may be repetitively filled to the predetermined amount to produce the desired single dosage on a microneedle.
