Abstract: A method is provided for fabricating a microneedle or a microneedle array using a mould (2) having at least a needle-forming cavity which comprises the step (A) of prefilling the needle-forming cavity with a solvent (1) before applying a microneedle-forming composition (3). The solvent (1) and microneedle-forming composition (3) are allowed to mix (step E) as a result of diffusion. The solvent is removed (step F), a flexible adhesive tape (4) can be applied on top of the mould (2), (step G), lifted (step H) so as to pull the microneedles out of the mould, giving an array of drug-filled dissolvable microneedles ready for application (step I).
Abstract: The present invention relates to a method for fabricating a microneedle which comprises the steps of spraying a composition into a mould, drying the composition and removal of the dried composition from the mould, thereby forming a microneedle that, when applied to the skin of a subject, pierces the stratum corneum to access the underlying tissue of the subject. The present invention also relates to a method for coating a microneedle which comprises the steps of spraying a composition onto a microneedle and drying the composition at an ambient temperature, thereby forming a coated microneedle that, when applied to the skin of a subject, pierces the stratum corneum to deliver the sprayed material to the underlying tissue of the subject.
