What are the types of drug delivery systems?

Figure 1: Different routes of drug delivery.

• Buccal drug delivery.
• Nasal drug delivery.
• Ocular drug delivery.
• Oral drug delivery.
• Pulmonary drug delivery.
• Sublingual drug delivery.
• Transdermal drug delivery.
• Vaginal/anal drug delivery.

What are targeted systems?

A target system is those aspects of the real-world system that are studied in order to gain knowledge about the phenomenon.

What are the benefits of targeted drug delivery?

The advantages to the targeted release system is the reduction in the frequency of the dosages taken by the patient, having a more uniform effect of the drug, reduction of drug side-effects, and reduced fluctuation in circulating drug levels.

What is automated drug delivery system?

An “automated drug delivery system” (ADDS) means a mechanical system that performs operations or activities, other than compounding or administration, relative to the storage, dispensing, or distribution of drugs.

What is transdermal drug delivery system?

Transdermal drug delivery systems (TDDS), also known as “patches,” are dosage forms designed to deliver a therapeutically effective amount of drug across a patient’s skin. The adhesive of the transdermal drug delivery system is critical to the safety, efficacy and quality of the product.

How are drugs targeted?

A drug target is usually selected depending on the requirements of the problem disease; hence, this step is primarily biologically or biochemically driven. Ideally, the target must be associated with a disease and it must have a suitable binding-pocket/active site into which a drug or drug-like molecule can bind.

Who originated concept of targeted drug delivery?

Background: More than a century ago, Paul Ehrlich proposed the idea of a drug working as a “magic bullet” that selectively eliminates diseased cells without harming the surrounding normal cells. Since then, much progress has been made in this field to broaden the scope for targeted delivery of drugs.

What is targeted drug discovery?

Abstract. Target discovery, which involves the identification and early validation of disease-modifying targets, is an essential first step in the drug discovery pipeline. Indeed, the drive to determine protein function has been stimulated, both in industry and academia, by the completion of the human genome project.

What is RES in drug delivery?

First, nanocarriers face many biological barriers, including cleansing by the reticuloendothelial system (RES) on the way to the targeted site. The RES takes the nanocarrier out of circulation shortly and accumulates those anti-cancer drug-carrying nanocarriers in the liver, spleen or bone marrow.

What is controlled drug delivery system?

controlled drug delivery a system used in dentistry that delivers an antimicrobial agent to the target site and maintains the desired concentration for enough time without development of resistant bacteria. forceps delivery extraction of a fetus from the maternal passages by application of forceps to the child’s head.

What is nano drug delivery system?

Many of the current “nano” drug delivery systems, however, are remnants of conventional drug delivery systems that happen to be in the nanometer range, such as liposomes , polymeric micelles, nanoparticles , dendrimers, and nanocrystals.

What does drug delivery systems mean?

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 drug delivery methods?

Oral Treatments. Comprising over 60\% of the drug market,the most common forms of over-the-counter prescriptions are pills or liquid-form medications.
