Inject non-needle medicine to treat skin cancer

UK researchers have developed a new way to inject drugs into the skin without using needles, to increase the amount of medication absorbed into the skin to improve the effectiveness of cancer treatment.

Pharmacist PhD student Desmond Morrow of Queen's University in Belfast has successfully tested a non-needle injection method for the treatment of skin cancer. In this way, the injection will be launched as a beam that is strong enough to penetrate the patient's skin instead of using the needle.

Mr. Morrow and colleagues found that compared to injecting drugs into the skin through biochemical tape, jet injection injections significantly increased the amount of drug penetration into the skin.

According to the team, the non-needle injection system enhances the effectiveness of photodynamic therapy, a technique that uses light rays - like lasers - in combination with a mildly active drug. to kill cancer cells.

Mr. Morrow said: 'Photodynamic therapy is a relatively new way of treating skin cancer, capable of destroying cancer cells. However, this therapy is sometimes not highly effective because of poor penetration of the active agent into the cancer cell. '

'Our research demonstrates that injecting drugs with rays will increase the amount of medicine absorbed into the patient's skin, while bringing the drug to the right place to kill cancer cells.'

According to the research team, 'this new technique has the potential to improve the effectiveness of skin cancer treatments.'

Mr. Morrow's needle-free injection method was introduced at the British Pharmaceutical Conference in Manchester, September 10, 2007.
