What are the different types of drug delivery?

Current research on drug delivery systems can be described in four broad categories: routes of delivery, delivery vehicles, cargo, and targeting strategies. Medications can be taken in a variety of ways—by swallowing, by inhalation, by absorption through the skin, or by intravenous injection.

What is a vaccine delivery system definition?

Vaccine delivery systems are generally particulate e.g. emulsions, microparticles, iscoms and liposomes, and mainly function to target associated antigens into antigen presenting cells (APC), including macrophages and dendritic cells.

What is new drug delivery system?

Drug delivery systems (DDSs) are developed to deliver the required amount of drugs effectively to appropriate target sites and to maintain the desired drug levels. Research in newer DDS is being carried out in liposomes, nanoparticles, niosomes, transdermal drug delivery, implants, microencapsulation, and polymers.

Which of the following is used as vaccine delivery system?

Typically, most vaccines are administered via the subcutaneous (SC) or intramuscular (IM) routes. Hypodermic injections are associated with pain and distress that might lead to poor patient compliance and require highly trained personnel for administration.

Why is drug delivery system important?

A drug delivery system is a formulation or a device that enables the introduction of a therapeutic substance in the body and improves its efficacy and safety by controlling the rate, time and place of release of drugs in the body.

What are the different types of vaccines?

There are several types of vaccines, including:

Inactivated vaccines.
Live-attenuated vaccines.
Messenger RNA (mRNA) vaccines.
Subunit, recombinant, polysaccharide, and conjugate vaccines.
Toxoid vaccines.
Viral vector vaccines.

What are the three main delivery forms for antigens in vaccines?

Most vaccine delivery systems are particulate (including nanoparticles, microparticles or adjuvant-formulated proteins). The size of the particle systems influences cellular targeting. The most effective sizes are in the 20–200 nm range.

What is injectable drug delivery?

Prefilled syringes are a user-friendly option that makes it easy and safe to deliver each dose—a significant differentiating value. Drug products in this ready-to-inject format offer patients a simple, comfortable administration process with predefined volumes, often also resulting in improved compliance.
