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.

What is half life of a drug?

How do you determine the half-life of a drug?

The half-life (t1/2) is the time it takes for the plasma concentration of a drug or the amount of drug in the body to be reduced by 50\%. The half-life of a drug can be determined using the following equation: t1/2 = (0.7 x Vd) / Cl, where Vd is volume of distribution and Cl is clearance.

What is duration of drug action?

The duration of action of a drug is known as its half life. This is the period of time required for the concentration or amount of drug in the body to be reduced by one-half. We usually consider the half life of a drug in relation to the amount of the drug in plasma.
