Injections may not be better than medicine

According to a survey: out-patient injection room, nearly half of transfusion patients take the initiative to doctor transfusion requirements. Many people think that shots better than they would taking effective, quick, in fact, this is a medical errors, medical experts, the patient presented the following advice:

transfusion effect is not necessarily faster than the drug
Some people think that oral bioavailability is not a high injection, but in fact, and now oral bioavailability can be up to 90%, but there is also a lot of new and efficient drugs, such as poor nutrition in patients after surgery, previously only available administered by injection, but now there are many highly effective nutritional supplements to complete the role of nutritional supplements without having to rely on injection.
Moreover, although the purity of injection compared with oral drug high, but because of its production process is relatively complex, to remove impurities will be lost when the active ingredients, so injection of the active ingredient is less than the oral agents.
Many patients believe that injections faster, in fact, although the fast onset of injection, but the final result is the same as with oral medication, but there is an oral absorption process. Patients should correct some misconceptions and reduce injection requirements.
injection adverse reactions heavier
Injection of the adverse reactions are usually heavier, frequency is also relatively high. On the human body for any form of open blood vessels are not a good thing. Although the injection in particular, high purity fluids, but still can not avoid the existence of which insoluble particles. These particles can be filtered through the infusion of the terminal device enters the human body, even the injection of acceptable quality are unable to reach the ideal “zero-particles” limit. Injection of the larger particles can cause local circulatory disturbance, causing thrombosis. Too many particles can cause partial obstruction and insufficiency, and further lead to tissue hypoxia, resulting in edema and phlebitis. More serious is the foreign body penetrated the organization are also available from blood vessels, due to the siege of macrophages and proliferation of granuloma caused by the infusion of drugs dispensed in the more particles contained in the higher. If the infusion set, the quality of medicine and then fail to pass the infusions there are problems, the consequences of particles will be more severe.
It is particularly worth mentioning is that a variety of drugs and drug use may be due to reaction between the incidence of adverse reactions increase. According to statistics, several kinds of drugs and used the incidence of adverse reactions were :2-5, and 4% ,6-10 species account for 10% ,11-15 species account for 28%.
medication can cure the disease as other shots
The four principles of safe medication is safe, effective, economical, applicable and serious adverse drug reactions, such as shock, many of which are from the injection of drugs, the proportion of oral small, so from a security perspective, the oral drug better, the doctor’s advice, the best, if not severe infection without injections. And the use of oral drugs are relatively inexpensive and easy to take, unlike injections can only be completed by professionals, the patient is time-saving option.
Therefore, to remind the patient, if oral drug, it is best not to take injection method can not be the best use of intramuscular injection. Even if the need should also be injected to minimize the number of injections, while reducing the types of joint use of injections to avoid adverse reactions and the emergence of incompatibility.
some patients must use the injection dose
While we believe that patients should not be able to take medicine injection, but some cases are to be administered by injection, like the patients have difficulty swallowing, vomiting, severe diarrhea, gastrointestinal diseases and other types of malabsorption, as well as the condition severe or rapid development of the organization of a high drug concentration required to do emergency treatment situation. Some patients can not guarantee that the amount of time and according to medication, the doctor suggested that he could be administered by injection, but still have to follow the principles of safe medication to minimize injection may cause harm to patients.
