Summary of DDS Drug Delivery System

00:00:00 - 00:35:00

This video discusses different methods of drug delivery, including diffusion, chemical reaction, and osmosis. It also describes a "smart delivery system" that uses external activation to increase the drug's release. Finally, the video discusses the use of controlled release systems in dentistry and how they can help patients with various conditions.

• 00:00:00 This lecture discusses controlled drug delivery systems and their various methods of achieving sustained release. The lecture also discusses the effects of environmental factors on drug release.
• 00:05:00 The video discusses the three fundamental mechanisms by which drugs are delivered to their target locations: diffusion, a chemical reaction, and osmosis. Finally, the video discusses a "smart delivery system" that uses external activation to increase the drug's release.
• 00:10:00 The three mechanisms for drug delivery via diffusion, chemical reaction, and osmotic pressure are described. Diffusion is the most common, followed by chemical reaction and osmotic pressure. Each has advantages and disadvantages, depending on the situation.
• 00:15:00 The DDS drug delivery system is a system that is water-driven and can give very precise release rates. It is used in various applications, such as in glaucoma and in controlled release of drugs.
• 00:20:00 This video discusses the use of controlled release systems to deliver medications to patients. One example is the use of artificial tears, which can last up to 18 hours. Another example is the use of contraceptive systems, such as the Norplant. These systems use small, implantable devices that release drugs over a period of up to five years. Finally, the video discusses the use of controlled release systems in dentistry.
• 00:25:00 DDS drug delivery systems can help patients with periodontal disease, cardiovascular disease, and schizophrenia. These systems use matrices and hollow fibers to deliver drugs over time, which can decrease the number of hospitalizations and suicides.
• 00:30:00 The transdermal delivery system (TDS) is a technology that allows for the delivery of drugs to the skin. It is a system that uses diffusion to deliver the drug to the skin, where it can then be absorbed by the body. Transdermal delivery systems are easy to apply and easy to remove, making them practical for use in clinical settings. One potential drawback of transdermal systems is that it takes time for them to reach a steady state.
• 00:35:00 The three methods of drug delivery discussed in this video are iontophoresis, electroporation, and ultrasound. Each has its own benefits and drawbacks, but all three could be used to deliver larger molecules to cells more effectively. Engineering and miniaturization of the units is a challenge, but these methods could help to improve the efficiency and efficacy of current drug delivery methods.
