A Primer On Drug Delivery Systems

The drug delivery industry has become one of the fastest emerging industries in the healthcare sector

. Drug delivery refers to the delivery of pharmaceutical substances to animals or human beings. The modes of delivery can be nasal, oral or rectal. For the drugs to prove effective, it is very important to ensure that they work in a controlled manner and get distributed throughout the body in a proper way.

Targeted drug delivery occurs when the administered drugs remains active within a particular area of the body. Targeted drug delivery can prove very effective in controlling the rapid increase of cells leading to cancerous tissues.

Most recent attempts in the realm of drug delivery include

Sustained-release formulations (in which the physician administers or releases the drug over a certain period in a controlled manner) and

Advance in intended delivery (in which the administered drugs remain active only in the targeted region of the body.

New drug delivery systems hold greater promise, as they tend to lessen the manufacturing costs. In addition, they have a better targeting ability. Due to this, the patients wont need to take high doses and so, will face minimum side-effects.

Transdermal drug delivery system, with the use of nanotechnology, can enhance the concentration and bioavailability of the drugs. Such a technology can prove to be a boon for patients suffering from Central Nervous System (CNS) or neurodegenerative disorders.

New drug delivery systems can alleviate some major concerns of the pharmaceutical industry and offer much better prospects of finding out new and better solutions for improving the current medical problems. Apart from Nanotechnology, some other drug delivery technologies are:

1.Sustained Release Formulations

2.Nano/ Micro particulate drug delivery systems

3.Self-emulsifying drug delivery systems

4.Intra-nasal drug delivery systems

5.Innovative drug delivery solutions concerning Biotech-derived products

One of the main objectives of drug development is to find drugs that will prove to be more effective in curing diseases and treating different medical conditions.
