Drug Delivery News and Research

RSS

Drug delivery is a term that refers to the delivery of a pharmaceutical compound into the body. Most common methods of delivery include the preferred non-invasive oral (through the mouth), nasal, pneumonial (inhalation), and rectal routes. Much research is now focussing on nanotechnology as a drug delivery method.

Development of magnetic cationic liposomes for targeting tumor microvasculature

A popular way to attack malignant tumors is using cationic liposomes as drug delivery systems.

Compounds derived from blue agave may be more effective way to deliver drugs to the colon

Compounds derived from the blue agave, a fruit used to make tequila, shows promise in early laboratory studies as a natural, more effective way to deliver drugs to the colon than conventional drug-carriers, according to chemists at the University of Guadalajara in Mexico.

Drug delivery system that consists of nanocrystals of a hydrophobic drug

The problem of efficiently delivering drugs, especially those that are hydrophobic or water-repellant, to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until reaching their targets.

Inhaled Celecoxib shows new promise for lung cancer treatment

In recent years, Cycloxygenase (COX)-2 has emerged as a therapeutic target for the prevention and treatment of various types of cancers.

New drug delivery method incorporates drug molecules in fat

Devastating blood-borne fungal infections that can be lethal for HIV/AIDS, cancer, and organ transplant patients may be treated more successfully, thanks to a new drug delivery method developed by researchers at the University of British Columbia in Vancouver.

Magnetic nanocrystals used to carry tumor-killing drugs

Imagine using a focused magnetic field to concentrate anticancer drugs in and around tumors, and then turning off the magnetic field so that the drugs then leave the body.

Ultrafine hydrogel nanoparticles: synthetic approach and therapeutic application in living cells

Ultrafine nanoparticles made of a lacy web of polymer and tiny pockets of water may prove to be an ideal vehicle for delivering light-activated drugs to tumors.

Nanoparticles rely on 'velcro effect' to target tumor cells

One of the basic tenets of targeted nanoparticle drug delivery is putting multiple targeting molecules on a nanoparticle surface will improve the ability of nanoparticles to stick to their targeted cell and deliver their drug cargos to the appropriate diseased cell.

Heat and pH-sensitive nanoparticles target tumors

Using a novel polymer that becomes unstable under the pH conditions inside tumor cells, investigators at Singapore's Institute of Bioengineering and Nanotechnology have developed a core-shell nanoparticle targeted to deliver drugs to tumors.

5 Feb 2007

Nanocarrier stimuli-activated gene delivery

One approach to developing tumor-specific drug delivery agents is to create nanomaterials that release a therapeutic payload only after reaching their intended target.

HIV/AIDS advocates call on Zimbabwe to address broad health care issues

Although some HIV/AIDS advocates in Zimbabwe are welcoming a recent pledge from the Zimbabwean government to provide increased access to antiretroviral drugs by the end of this year, they also are stressing the need to address a broader crisis in the country's health care system, VOA News reports.

Dendrimer-based targeted delivery of an apoptotic sensor in cancer cells

Taking a critical step toward the development of a multifunctional nanoscale anticancer agent that can detect cancer, treat it, and then report on the success or failure of that treatment, investigators at the University of Michigan have developed a nanoscale sensor of cell death.
