Drug Delivery: Controlled Release
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...
متن کاملControlled Drug Delivery System
Controlled release drug delivery systems provide uniform concentration of drug to the absorption site and thus allow the maintenance of plasma concentration within the therapeutic range which minimizes not only the side effects but also the frequency of administration. Oral Sustained release (SR) products provide an advantage over conventional dosage forms by optimizing properties of drugs in s...
متن کاملPulsatile Drug Delivery Systems: An Approach for Controlled Drug Delivery
Pulsatile systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery and increasing patient compliance. These systems are designed according to the circadian rhythm of the body. The principle rationale for the use of pulsatile release is for the drugs where a constant drug rel...
متن کاملConductive polymer nanotube patch for fast and controlled ex vivo transdermal drug delivery.
AIM To uptake and release hydrophilic model drugs and insulin in a novel conductive polymer (CP) nanotube transdermal patch. MATERIALS & METHODS The externally controlled transdermal delivery of model drugs and insulin were tested ex vivo and results were compared with CP films. The unique intrinsic properties of CPs provide electrostatic interaction between the model drugs and polymer backbo...
متن کاملControlled Drug Delivery Using Microdevices.
Therapeutic drugs administered systematically are evenly distributed to the whole body through blood circulation and have to cross many biological barriers before reaching the pathological site. Conventional drug delivery may make drugs inactive or reduce their potency as they may be hydrolyzed or degraded enzymatically and are rapidly excreted through the urinary system resulting in suboptimal...
