What are the delivery systems of drugs?

Drug supply systems are the methods that are used to ensure that medicines get into the body and reach the area where they are needed. These systems must take into account a number of needs, from easy delivery to drug efficiency. Several companies specialize in the development of drug provision methods, launch these products to pharmaceutical companies and other pharmaceutical companies develop their own systems. Many of these methods are patented and proprietary. Delivery systems must also consider the way the drug is metabolized by the body. For example, some drugs are destroyed in the intestinal tract, which means that they cannot be introduced into the body in this way. Others may be dangerous in large quantities, which means that the time issue of the patient's safety should be used for offending.

Topical drug supply systems include the introduction of the drug to the body surface in formulation that can be absorbed. Skin skin patch is an example of topical systems intoGiving drugs. Other systems include sprays applied to nose mucous membranes, inhalation aerosols, eye drops or creams that can be shaking into the skin. These systems are often very easy for patients, which makes them attractive.

enteral supplies of drug supply rely on the introduction of the drug into the digestive tract, classic mouth or rectum. Direct infusion through the stomach tubes is another possibility to obtain drugs into the digestive tract. Perineral systems include injection or infusion of compounds into the body. For example, many vaccines are supplied through perineral systems, as well as drugs used in chemotherapy that are inserted for reliable administration. Implants and infusion pumps can be used to supply a drug in patients with chronic conditions.

In all cases, the aim of the drug supply system is to obtain the right dose to the right place. Patients tend to preferMethods that are painless and easy, and therefore many drugs come in the form of local and enteral methods that can be received by mouth or applied directly to the skin. In clinical environments, the peteral routes may be more common, especially in controlled substances, as these methods allow more control over how and when drugs are used.
