Drug Delivery Systems 4. Implants in Drug Delivery
The Journal of Clinical Pharmacology, 1990In comparison with many of the other drug delivery systems, implantable pumps and implants for variable rate delivery are at a crude stage of development. Although exceptions exist, the typical implantable pump consists of an electromechanically complex mechanism to regulate drug delivery from a percutaneous refillable reservoir, while power to drive ...

Drug Delivery Systems 5A. Oral Drug Delivery
The Journal of Clinical Pharmacology, 1991The two main advantages of controlled drug delivery systems are: maintenance of therapeutically optimum drug concentrations in the plasma through zero‐order release without significant fluctuations; and elimination of the need for frequent single dose administrations.

Nanomedicine and Drug Delivery
Medical Clinics of North America, 2007This article discusses the use of nanotechnology in drug delivery approaches. Magnetic nanotechnology is finding wide applications in medicine, most notably in MRI and magnetic separation. The impedance biosensor is expected to find applications in monitoring cytokines in cancer, bone turnover markers in osteoporosis, and understanding neural ...

Cancer, 1986
Cancer chemotherapy drugs are neither specific, i.e., they do not act exclusively on the metabolic pathways of cancer cells, nor are they targeted solely toward cancer cells. However, recent research has begun to address, in part, the latter issue. Improved delivery of chemotherapeutic agents to tumor tissue in man appears to be an achievable goal in ...

American Journal of Health-System Pharmacy, 1991
New and emerging drug delivery systems for traditional drugs and the products of biotechnology are discussed, and the role of the pharmacist in ensuring the appropriate use of these systems is outlined. Advantages of advanced drug delivery systems over traditional systems are the ability to deliver a drug more selectively to a specific site; easier ...

Peptides have been used as drugs to treat various health conditions, and they are also being developed as diagnostic agents. Due to their receptor selectivity, peptides have recently been utilized for drug delivery to target drug molecules to specific types of cells (i.e. cancer cells, immune cells) to lower the side effects of the drugs. In this case,

Although the eye is an accessible organ for direct drug application, ocular drug delivery remains a major challenge due to multiple barriers within the eye. Key barriers include static barriers imposed by the cornea, conjunctiva, and retinal pigment epithelium and dynamic barriers including tear turnover and blood and lymphatic clearance mechanisms ...

Delivery of Drugs with Ultrasound
Echocardiography, 2001In this article we discuss the potential role of microbubbles, traditionally used as ultrasound contrast agents, for site‐specific drug delivery. To reach this goal, microbubbles capable of carrying a drug payload are being developed. To ensure that these microbubbles reach sufficient local concentration at disease sites, specific targeting for ...

Expert Opinion on Drug Delivery, 2005
In the last decade, interest in physical organogels has grown rapidly with the discovery and synthesis of a very large number of diverse molecules, which can gel organic solvents at low concentrations. The gelator molecules immobilise large volumes of liquid following their self-assembly into a variety of aggregates such as rods, tubules, fibres and ...
