Microneedle Array Comparison With Hypodermic Needle
Microneedle may refer to : * Elements of a microneedle array/patch for transdermal drug delivery * microneedling, a mechanical/RF skin treatment used e.g. for Collagen induction therapy * a microinjector Microinjection is the use of a glass micropipette to inject a liquid substance at a microscopic or borderline macroscopic level. The target is often a living cell but may also include intercellular space. Microinjection is a simple mechanical pro ... See also * * {{disamb ...

Microneedle Drug Delivery
Microneedles or Microneedle patches or Microarray patches are micron-scaled medical devices used to administer vaccines, drugs, and other therapeutic agents. While microneedles were initially explored for transdermal drug delivery applications, their use has been extended for the intraocular, vaginal, transungual, cardiac, vascular, gastrointestinal, and intracochlear delivery of drugs. Microneedles are constructed through various methods, usually involving photolithographic processes or micromolding. These methods involve etching microscopic structure into resin or silicon in order to cast microneedles. Microneedles are made from a variety of material ranging from silicon, titanium, stainless steel, and polymers. Some microneedles are made of a drug to be delivered to the body but are shaped into a needle so they will penetrate the skin. The microneedles range in size, shape, and function but are all used as an alternative to other delivery methods like the conventional hypodermic ...

Transdermal Drug Delivery
A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream. An advantage of a transdermal drug delivery route over other types of medication delivery (such as oral, topical, intravenous, or intramuscular) is that the patch provides a controlled release of the medication into the patient, usually through either a porous membrane covering a reservoir of medication or through body heat melting thin layers of medication embedded in the adhesive. The main disadvantage to transdermal delivery systems stems from the fact that the skin is a very effective barrier; as a result, only medications whose molecules are small enough to penetrate the skin can be delivered by this method. The first commercially available prescription patch was approved by the U.S. Food and Drug Administration in December 1979. These patches administered scopolamine for motion sickness. In order to overcom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microneedling
Collagen induction therapy (CIT), also known as microneedling, dermarolling, or skin needling, is a cosmetic procedure that involves repeatedly puncturing the skin with tiny, sterile needles (microneedling the skin). CIT should be separated from other contexts in which microneedling devices are used on the skin (e.g., transdermal drug delivery, vaccination). It is a technique for which research is ongoing, but has been used for a number of skin problems including scarring and acne. Some studies have also shown that, when combined with minoxidil treatment, microneedling is able to treat hair loss more effectively than minoxidil treatment alone. Platelet-rich plasma (PRP) can be combined with collagen induction therapy treatment in a form of dermatologic autologous blood therapy. PRP is derived from the patient's own blood and may contain growth factors that increase collagen production. It can be applied topically to the entire treatment area during and after collagen induction th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
