The colon is a promising site for drug targeting owing to its long transit time and mild proteolytic activity. The aim of this study was to prepare new low methoxy amidated pectin/NaCMC microspheres cross-linked by a mixture of Zn(2+) and Al(3+) ions and test their potential for colonic targeting of progesterone. A 2(4) factorial design was carried out to optimize the preparation conditions. Hi...

During the last decade there are new developments in site-specific formulations for targeting drug to the colon. Colon has proved to be a site for the absorption of poorly soluble drugs. Micro carriers as colon drug delivery System has gained importance for the delivery of the drug in the colon because of their increase biocompatibility, controlled release of drug and higher stability. This rev...

Bacterial infections are a major complication in human healthcare. Bacteria tracing and targeted delivery of antibiotics to bacterial infection sites being developed reduce the high mortality caused by pathogenic infections. Owing challenges accurate diagnosis infection, particularly identification biomaterial‐related bacteria, use bacteria‐targeting nanomaterials has become increasingly import...

Lipid-based innovations have achieved new heights during the last few years as an essential component of drug development. The current challenge of drug delivery is liberation of drug agents at the right time in a safe and reproducible manner to a specific target site. A number of novel drug delivery systems has emerged encompassing various routes of administration, to achieve controlled and ta...

Many bioactive natural products are derived from traditional Chinese medicine. Some of them showed good treatment potential in tumor chemotherapy. However, limited by the poorly solubility and non-selective toxicity most products, their antitumor efficacy could not be further applied clinicals. Nano-drug delivery systems provided platforms for treatment, many microenvironment-responsive nano-de...

Over the past decades, the treatment of illness has been accomplished by administering drugs to the human body via various pharmaceutical dosage forms, like tablets. These traditional pharmaceutical products are still commonly seen today in the prescription and over-the-counter drug marketplace. To achieve and maintain the drug concentration in the body within the therapeutic range required for...

On April 17, 2010, scientists from academia, the National Cancer Institute (NCI), and the Food and Drug Administration (FDA) assembled at "The NCI Image Guided Drug Delivery Summit," in Washington D.C., to discuss recent advances, barriers, opportunities, and regulatory issues related to the field. The meeting included a scientific session and an NCI/FDA session, followed by a panel discussion ...

Traditional drug delivery strategies involve drugs which are not targeted towards the desired tissue. This can lead to undesired side effects, as normal cells are affected by the drugs as well. Therefore, new systems are now being developed which combine targeting functionalities with encapsulation of drug cargo. Protein nanocages are highly promising drug delivery platforms due to their perfec...

Nanoscale carriers are of increasing interest for use in anticancer therapy because they can deliver drugs in a targeted way. Ideally, nanocarriers combine passive and active delivery mechanisms, by integrating targeting ligands on the surface of their stealth corona using simple and efficient conjugation chemistry. This feature article summarizes the conventional and newly explored conjugation...
