Understanding Drug Delivery

The drug delivery industry is one of the fastest growing healthcare sectors. It is concerned with the delivery of pharmaceutical compounds to both, human and animals. Delivery methods include many distinct routes, including nasal, oral, rectal and inhalation. To ensure that the drugs prove effective, it is essential for them to work in a controlled manner so that they get properly distributed in the body. Targeted drug delivery usually ensures that the concentration of the drug is more in some areas than others, and thus helps in controlled drug delivery. It can be very crucial in certain cases, wherein the drug has to affect or inhibit the rapid increase of harmful tissues, such as cancerous tissues.

Doctors and Scientists the world over are constantly trying to discover new, more effective drug delivery procedures. Nanotechnology is one of the most recent and most successful drug delivery technology developed in recent years. Nanotechnology not only controls small-scale matters but also allows the drugs to permeate the cell walls.

The main objective of drug development is to figure out drugs that are not only more efficient but also more useful in curing different diseases or illnesses. Drug development can also play a major role in discovering the medical, physical and chemical properties of latest substances.

Novel drug delivery systems provide better prospects of finding new and better solutions for ameliorating medical problems. Besides Nanotechnology, other novel drug delivery technologies are as follows:

Nano/ Micro particulate drug delivery  systems
Sustained Release Formulations
Intra-nasal drug delivery systems
Self-emulsifying drug delivery  systems
Innovative drug delivery solutions for the sake of  Biotech-derived products

New drug delivery systems hold great promise. In fact, transdermal drug delivery system, through nanotechnology, can increase the bioavailability and concentration of the drug. Such a drug delivery technology can be a boon for patients suffering from neurodegenerative or Central Nervous System (CNS) disorders.

Drug Delivery System

Drug delivery refers to the delivery of a pharmaceutical substance to human beings or animals. Modes of delivery include oral, nasal and rectal. However, administration of drugs through these modes may lead to terrible conditions.

Therefore, physicians prefer to deliver several peptides and protein drugs through injections.

To work efficiently, the drugs have to act in certain controlled manner to distribute the drug in the body. Targeted drug delivery takes place when the drugs remain active within a specific region of the body. Targeted delivery is important when the drugs need to have an effect on rapid increase of cells that lead to cancerous tissues.

Recent attempts in the area of drug delivery include, advance in intended delivery where the drugs are only active in the targeted area of the body (for instance, in cancerous tissue) and sustained-release formulations wherein the physician releases the drug over a period in a certain controlled manner.

The main aim of drug development is to discover drugs that are more effective and help to cure several symptoms of medical condition or illness. Drug development is often required to discover the chemical properties of latest substances, their strength and chemical composition. It is also necessary for the process of drug development to meet the regulations laid down by the authorities who certify drugs.

Nanotechnology:

All around the world, physicians attempt to find methods for more efficient drug delivery and drug development.

Nanotechnology is an effective method developed in the recent years. This mechanism simply makes possible for the drugs to saturate cell walls. The nanotechnology methods play a vital role in pharmaceutical industry.

The new drug delivery system might help alleviate some of the concerns of the pharmaceutical industry as it has answers to:

1. Better targeting ability: Then, patients will have to take low doses and therefore, there will be fewer side effects.

2. Reduction of manufacturing costs

3. Solubility enhancements

In very simple terms, drug delivery system is a process in which a bioactive agent is released at a specific site and at a specific rate. The drug delivery industry is evolving rapidly for the benefit to the human community.

Nanotechnology – Revolution in the Field of Medicine

In the recent years, there has been a tremendous development in the field of nanotechnology. Nanotechnology is a field of applied science, which deals in building machines and bots at microscopic levels. Due to development in nanotechnology, there have been many developments in various fields of science, especially in the field of medicine.

 

With the help of nanotechnology, carrying out a complex heart surgery is very much possible. Doctors have started making use of nanobots to cure certain diseases. These nanobots also help in rectifying certain disorders in the human body.

 

Nanotechnology in Drug Development:

 

Recently, scientists are developing effective and better drug delivery systems using nanotechnology. Scientists are using nanoparticles to design a drug delivery system that may improve the pharmaceutical and therapeutic properties of a drug and help better processes such as Drug screening. Nanaoparticles have remarkable properties that drastically enhance the drug delivery. Due to their microscopic sizes, nanoparticles get an easy access in the cells.

 

There are numerous developments in the drug delivery owing to nanotechnology. One such development using nanotechnology is the transfer of drugs into the cytoplasm of cells through the cell membrane. This is an important development, because to hinder certain diseases from the body, the drug needs to enter the cell membrane.

 

 To make a drug molecule effective in the body, it needs a triggered response. To do so, scientists are using nanotechnology. Scientists are developing drugs using nanotechnology that automatically activate, once they enter the human body.

 

Many researchers believe that it is possible to develop a drug delivery system that may prove beneficial in treating cancer and infectious diseases using nanotechnology. By far, they have identified six types of nano-enabled delivery systems that have considerable potential in treating cancer and other infectious diseases.

 

With the help of nanotechnology, scientists have developed injectable drugs, which are more pleasing for the patients, who receive them and at the same time are easy to administer. Better opportunities are coming up in the development of implantable delivery systems, due to the use of nanotechnology, especially in terms of injectable drugs. 

 

With so much of development taking place in the field of drug delivery systems, researchers believe that in the near future nano-enabled medicines will have a tremendous evolution and will produce true nanomedicines.
