Polymers in Drug Delivery
Polymers are being used extensively in drug delivery due to their surface and bulk properties. They are being used in drug formulations and in drug delivery devices. These drug delivery devices may be in the form of implants for controlled drug delivery. Polymers used in colloidal drug carrier systems, consisting of small particles, show great advantage in drug delivery systems because of optim...
متن کاملPolymers and drug delivery systems.
In the treatment of health related dysfunctions, it is desirable that the drug reaches its site of action at a particular concentration and that this therapeutic dose range remains constant over a sufficiently long period of time to alter the process. However, the action of pharmaceutical agents is limited by various factors, including their degradation, their interaction with other cells, and ...
متن کاملStimuli-responsive polymers and their applications in drug delivery.
Interest in stimuli-responsive polymers is steadily gaining increasing momentum especially in the fields of controlled and self-regulated drug delivery. Delivery systems based on these polymers are developed to closely resemble the normal physiological process of the diseased state ensuring optimum drug release according to the physiological need. Also termed 'environmental-sensitive' or 'smart...
متن کامل2 Applications of Polymers in Buccal Drug Delivery
Absorption of drugs through the oral cavity was noted as early as 1847 and systemic studies of oral cavity absorption were first reported in 1935 [1]. Since then, substantial effort has been focused on drug absorption from a drug delivery system in a particular region of the oral cavity [2-5]. As a site for drug delivery, the oral cavity offers many advantages over other routes of drug administ...
متن کاملAlginate Polymers for Drug Delivery
Acknowledgements We would like to express our gratitude to everyone who advised and assisted with our research throughout our time at ENSIC. We sincerely appreciate their time and efforts. Abstract The goal of this project was to investigate the properties of alginate stabilized emulsions and their potential role for drug delivery. The polymer acts as a barrier between phases in oil-in-water em...
