What polymers are used in drug delivery?

Biodegradable and bio-absorbable polymers Among the synthetic and biodegradable polymers, aliphatic polyesters such as poly (glycolic acid), poly (lactic acid), poly (caprolactone) and polydioxanone, are most commonly used and applied to drug delivery systems.

How polymers are used in drug delivery system?

Polymers have played an integral role in the advancement of drug delivery technology by providing controlled release of therapeutic agents in constant doses over long periods, cyclic dosage, and tunable release of both hydrophilic and hydrophobic drugs.

What polymer shape is important for drug delivery?

Historically, more traditional drug delivery systems have focused on spherical carriers. However, there is a growing interest in pursuing non-spherical carriers, such as elongated or filamentous morphologies, now available due to novel formulation strategies.

Which polymer is used in mucoadhesive drug delivery system?

Gastrointestinal Mucoadhesive Drug Delivery Systems Bioadhesive retentive system involves the use of bioadhesive polymers, which can adhere to the epithelial surface in the GIT. Using bioadhesive would be achieved increase GI transit time and increase in bioavailability.

How are polymers used in drug delivery systems?

Polymers for drug delivery systems Polymers have played an integral role in the advancement of drug delivery technology by providing controlled release of therapeutic agents in constant doses over long periods, cyclic dosage, and tunable release of both hydrophilic and hydrophobic drugs. From early beginnings using off-the-shelf mate …

How are polymers used in controlled release formulation?

Polymers can be used as film coatings to disguise the unpleasant taste of a drug, to enhance drug stability and to modify drug release characteristics. As a consequence, increasing attention has been focused on methods of giving drugs continually for a prolonged time periods and in a controlled fashion.

How are polymers used in the medical field?

Polymers can be used as taste masking agents, to enhance stability of drug and to modify drug release characteristics. Biodegradable materials are used in medicine and other areas. In recent years there has been increase in use of biodegradable polymers. Biodegradable polymers are of two classes; synthetic and natural polymers.

When is the deadline for polymers for drug delivery?

Deadline for manuscript submissions: closed (30 November 2013) . Polymers have performed and will continue to play a central role in drug delivery.
