摘要：
The present invention relates to a microneedle patch composition comprising one or more microneedles each comprising: (a) a tapered tip portion containing a therapeutically active ingredient dispersed in a matrix of a biodegradable polymer capable of providing sustained release of the therapeutically active ingredient over a period of at least two days after insertion of the microneedle or microneedles into the skin, and (b) a fast dissolving microneedle backing layer portion containing a water-soluble polymer overlayering the tip portion, said microneedle or microneedles being attached to and extending from an adhesive surface of a removable substrate.
