A patchless dissolving microneedle delivery system enabling rapid and efficient transdermal drug delivery
نویسندگان
چکیده
Dissolving microneedles (DMNs) are polymeric, microscopic needles that deliver encapsulated drugs in a minimally invasive manner. Currently, DMN arrays are superimposed onto patches that facilitate their insertion into skin. However, due to wide variations in skin elasticity and the amount of hair on the skin, the arrays fabricated on the patch are often not completely inserted and large amount of loaded materials are not delivered. Here, we report "Microlancer", a novel micropillar based system by which patients can self-administer DMNs and which would also be capable of achieving 97 ± 2% delivery efficiency of the loaded drugs regardless of skin type or the amount of hair on the skin in less than a second.

Dissolving and biodegradable microneedle technologies for transdermal sustained delivery of drug and vaccine
Microneedles were first conceptualized for drug delivery many decades ago, overcoming the shortages and preserving the advantages of hypodermic needle and conventional transdermal drug-delivery systems to some extent. Dissolving and biodegradable microneedle technologies have been used for transdermal sustained deliveries of different drugs and vaccines. This review describes microneedle geomet...
متن کاملFabrication of polymeric microneedle arrays containing Amphotericin-B for transdermal drug delivery
Background and Aim: Drug delivery through the microneedle array has been considered as an easy and non-invasive method in recent years. The purpose of this study was to design and construct an array of biodegradable polymeric microneedles containing Amphotericin-B to introduce this system and its use in the treatment of cutaneous lesions caused by Leishmania major parasite inoculation as a mode...
متن کاملDesign and physicochemical characterisation of novel dissolving polymeric microneedle arrays for transdermal delivery of high dose, low molecular weight drugs
We describe formulation and evaluation of novel dissolving polymeric microneedle (MN) arrays for the facilitated delivery of low molecular weight, high dose drugs. Ibuprofen sodium was used as the model here and was successfully formulated at approximately 50% w/w in the dry state using the copolymer poly(methylvinylether/maleic acid). These MNs were robust and effectively penetrated skin in vi...
متن کامل[Development of a novel transdermal delivery system of alendronate, a nitrogen containing bisphosphonate, using a new type of hydrophilic patch and dissolving microneedle arrays].
Alendronate is a nitrogen-containing bisphosphonate that is widely used for the treatment of osteoporosis in postmenopausal women. However, the oral bioavailability (BA) of alendronate is approximately 0.9 to 1.8%. In addition, the oral administration of alendronate has been associated with mucosal damage including gastritis, gastric ulcer, and erosive esophagitis. To prevent these adverse effe...
متن کاملMicro Needle Patches in Drug Delivery – a Review
Drugs are administered by using different drug delivery systems. A number of drug delivery systems have evolved over the years. In the last 20 years TDDS (Transdermal drug delivery system) has been growing at a rapid pace. Now the micro needles are being developed as a novel drug delivery system. The micro needle skin patch system is also a drug delivery system, which will be used transdermally...
