Per Os (orally) how it's like? Oral administration method

26 Oct 2016

Modern medicine dates back to ancient times, which is why there are so many Latin and Greek words, as a tribute. For example, most of the medicines prescribed orally: it's like? This question can be answered, even those who are far from the Latin - too often the term is used in everyday life.

Two major mode of administration.

And what in general there are ways of administering drugs to the patient? All the options are reduced to two - enteral and paraenteral.

The first way include:

  • Oral.
  • Sublingual.
  • Buccal.
  • Translingual
  • Vaginal
  • Rectal.

In the second category are:

  • Inhalation. This also can include the intranasal route of administration.
  • Injecting. All intramuscular, intravenous and subcutaneous injection.
  • Introduction to the cavity. In such cases, drugs directed into the peritoneal cavity or joint cavity.

The effectiveness of injections and inhalations

Described in the second column of the methods allow agents how to get to places faster impact and can affect the outcome. At the same stuffy nose spray is easier to use than doing intramuscular injections. Since we remembered about the injections.

What does all depend, will do them in a vein, muscle, or skin? From a drug that will be administered.

Some substances, when administered intramuscularly, can cause severe pain and even death of rapidly growing tissues. The second important factor is the time of drug action. The most rapid change in the state give intravenous injections, just a few seconds. But from the muscle tissue the drug must be absorbed into the bloodstream and then he will be able to act on the body.

Skin is the case in much the same. Cavernous application is rather an exception to the rule. It is used during surgery and after, in the case of serious damage to the joints.

What is by mouth (per os)?

And what enteral methods? All of them are connected with the veins of the gastrointestinal tract. Most often prescribed drugs orally, i.e. - Through the mouth. Ordinary tablets, capsules, powders, tinctures, solutions. It is enough to swallow, drink, chew and after 15-20 minutes you will feel the first changes. The sequence of the penetration of the drug is quite simple:

  • The drug enters the stomach, where the processes of digestion begins.
  • Suction can begin in the stomach or intestine, in the artery.
  • The active molecules are carried by the blood throughout the body.
  • Pass through the liver where they lose some of their activity.
  • Output by the kidney or liver.

Negative aspects of oral administration

The method seems very simple, but at the same time it will not work for seriously ill patients. Babies are also very difficult to get to chew or swallow the tablet, especially if it is eerily bitter. In this case it is necessary to look for alternative ways of delivery.

Another significant drawback is the passage through the liver. As you know, this organ - our main defender of any toxic substances. At the heart of the action of the drug may well lie with what is apprehended as a poison. And then the liver will help us "bearish" service, reducing the effectiveness of the drug. The drug may be inactive, as it will connect the liver proteins.

In this state the substance does not act on the body, but can be in fairly high concentrations. Adverse conditions will contribute to the output of the drug from the bound state.

The reason for the success and the attitude to the recommendations.

But why to dramatize? Oral administration of drugs method was one of the first medicine. And in the history it has shown its effectiveness and simplicity. After all, a person does not need outside help for taking drugs. Even exhausted people quite easily will transfer technique, if he is still conscious. It does not generate any negative emotions and associations. You're sure to remember children in the study, to prick. If all the agents were administered by injection, the child would be impossible to drag to the hospital. In addition, the best option is to influence the esophagus, stomach and intestines.

And do not forget to read carefully the recommendations before use. Many people decide that it is not necessary to wash down pills with plenty of water. And some of the drugs in this respect carelessly, can lead to the development of gastric ulcers.Do not forget take Mildronate for better results.

Eating before or after meals is also an important point. Features of metabolism and blood circulation no one has canceled. On this depends the optimal effectiveness of the drug, which has been proven in numerous clinical studies.

Knowing how it is orally, you can always consult your grandmother or any other relative. But do not overdo it with the drugs, the use of more than 5 medications at the same time increases the risk of side effects by 50%.
