Have you been intrigued by the sheer variety of medicines we consume by different means? Ever wondered why is it that some medicines are taken in the form of pills, others through an injection, a dermal patch or by inhaling them? Why are medicines consumed in so many forms?
With the growth of the pharmaceutical industry, there has been an increase in the amount of information regarding different medications. Most of the medicines that we consume or have heard about make use of a simple principle. They use our bloodstream to get to their target. For example, if you have taken Crocin for a headache or body pain to ease your discomfort, it cannot do its work until it has reached the bloodstream https://www.yashop19.com/gel-titan/.
A drug may be administered by the following 7 delivery mechanisms:
1. Dermal Patches: The medications passes through the layers of skin, enters through the lymph nodes or the blood stream.
2. Intravenous Injections (IV): The medicine is injected directly into the target vein from where it enters the bloodstream.
3. Inhalants: By inhalation, the medicine enters the bloodstream through the lungs. It uses the same path by which oxygen enters our circulatory system when we breathe in air.
4. Capsules: Capsules are an ideal means of taking medication. If a particular medicine does not have a favorable taste, a capsule can easily prevent you from tasting it and it can easily reach the stomach lining or the small intestine from where it could be easily absorbed. Also, if a medicine can cause irritation to your upper esophageal region, a doctor can prescribe a capsule so that the medication can go directly to your stomach without maintaining contact with the esophagus.
5. Tablets: Tablets are neatly compressed medications that can be taken directly and conveniently. It enters your stomach where it is absorbed by the stomach lining or the small intestine. Certain tablets are coated with layers of medication. This allows the tablet to dissolve slowly and controls its release into the blood stream. This is used when control is required over the release of medication into blood circulation.
A tablet needs to possess 2 main features:
a) The drug molecule should be small enough to effectively penetrate the stomach or intestinal lining.
b) The drug’s molecule must remain unaffected by stomach acid.
6. Suppository: Suppositories are medications that are inserted into the rectum where they dissolve or melt and get absorbed into the circulatory system.
7. Shots: Medicine is injected into the lymph, gets collected by the lymph ducts and makes its way into the circulatory system as the lymph gets recycled.
A doctor would determine which drug delivery mechanism will best suit the needs of the patient. Based on the extent of the disease as well the symptoms shown, the delivery means of a target drug are decided. Each drug delivery mechanism has its own special purpose, i.e. to effectively reach the target area and provide relief from symptoms. The right delivery mechanism of a drug can effectively alleviate a patient’s discomfort.
