NDDS stands for New Drug Delivery System. It refers to the technologies and techniques used to enhance the delivery and effectiveness of pharmaceuticals. NDDS aims to provide safe, targeted, and controlled drug delivery to the patient’s body.

The most common types of NDDS are:

1. Liposomes: These are microscopic lipid-based vesicles that enclose drugs and help them target specific cells and tissues.

2. Nanoparticles: These are small particles that can contain drugs and be designed to target specific cells, allowing drugs to reach their destination more precisely.

3. Microspheres: These are tiny microsized spheres that can deliver drugs over longer periods of time and reduce the frequency of dosing.

4. Implants: These are devices that are implanted into the body and can release drugs over a longer period of time.

NDDS has several advantages over traditional drug delivery systems. Some of the benefits are:

1. Precise delivery: NDDS allows drugs to be delivered to specific sites in the body, increasing their effectiveness and reducing side effects.

2. Controlled release: NDDS can help regulate the release of drugs over longer periods of time, reducing the need for frequent dosing.

3. Increased bioavailability: NDDS can improve the solubility and bioavailability of certain drugs, making them more effective.

4. Targeted delivery: NDDS can be designed to target specific cells or tissues, increasing drug efficacy and reducing side effects.

In conclusion, NDDS is an emerging field that promises to revolutionize drug delivery and enhance the effectiveness and safety of pharmaceuticals.
