Important Antidotes List


What are Antidotes ? 

The Word Antidote Derived From A Greek Word “antididonai”  Which Means Give Against So ” Antidotes are Any Substance  which Are Used To oppose the effects of poisons without causing any damage to The body” .

How The Poison Enter Into The Body ?

The Poison In Any Form may be  taken in by the breath Or swallowed, Absorbed Through the thinner and more delicate mucous membranes, Or absorbed through the skin, or implanted by stings, bites, or other wounds.

There Are A lot Of Antidotes In The Medical Field Today But Some Antidotes Are Very Important And Need To Be Remembered Because Of Their Frequent Use In The Emergency Situations.  Knowledge About Antidotes Is Very Important For All Medical Professionals Especially Those Who Are Working In Health Care Settings.Here Are Some Of The Types And List Of Very Important And Frequently Used Antidotes ;

Scientists Develop Artificial Womb To Help Premature Babies

Artificial Womb

Scientists Develop Artificial Womb To Help Premature Babies:
Scientists in the United States have developed a womb-like bag called an extra-uterine support device that would transform care for extremely premature babies, considerably rising probabilities of survival.While the new development isn’t specifically a synthetic uterus tank, physicians have created a uterus-like “biobag” that’s capable of sustaining premature foetal lambs very shortly when they start development.
Doctors said that the pioneering approach may radically improve outcomes for babies born so early that they can not breathe, feed or fight infection without medical help.

The team spent three years evolving their system through a series of four prototypes – starting with a glass incubator tank and reaching to the present fluid-filled bag.

Six preterm lambs tested within the most up-to-date prototype were physiologically similar to a 23- or 24-week-gestation human baby and were ready to grow during a temperature-controlled, near-sterile surroundings

In pre-clinical studies with lambs, the researchers were ready to mimic the uterus surroundings and therefore the functions of the placenta, giving premature offspring a vital chance to develop their lungs and other organs.
The lambs were kept within the biobags for four weeks. throughout this time, they grew hair; their lungs developed; and that they reached the point where they might survive on their own.

Remarkably, the eight lambs within the trial developed commonly within the artificial womb and every survived, proving that the biobag with success mimicked the natural conditions found within the uterus—and paving the means for a brand new life-saving device for humans.

At that age, a human baby weighs very little quite 500 grams, its lungs don’t seem to be ready to deal with air and its probabilities of survival are low. Death rates are up to 70 % and people who do survive face life-long disability.

The scientists created amniotic fluid in their science lab and originated the system so that this flowed into and out of the bag.
The team is in discussions with the United States of America Food and Drug Administration (FDA) and predicts that babies might be incubated within the system within three years in the 1st clinical test.
In light of this progress, specialists assert that artificial wombs could also be a reality within the next 10-20 Years.

Drugs Used In Pregnancy

Drugs Used In Pregnancy


Drugs Can Have Harmful Effects On The Fetus At any Time In Pregnany.Its Very Important To Keep In Mind When Prescribing For A Pregnant Women.In The First Trimester Of Pregnany Drugs Can Produce Malformation (Teratogenesis).Third And eleventh Week Of Pregnany Is more Critical Time For Teratogenesity.

The Second And Third Trimester Can Effect The Growth And Functional development Of The Fetus. And Drugs Given Just Before Term Or During Labour Can Have Adverse Effects On The Neonates Or On The Labour.

According To FDA There Are Five Categories Of Drugs ,A,B,C,D or X

Category A

Adequate and well-controlled studies have failed to demonstrate a risk to the foetus within the first trimester of pregnancy (and there’s no evidence of risk in later trimesters).

Category B

Animal studies have failed to demonstrate a risk to the foetus and there are not any satisfactory and well-controlled studies in pregnant women.

Category C

Animal reproduction studies have shown an adverse impact on the foetus and there are not any adequate and well-controlled studies in humans, however potential advantages might warrant use of the drug in pregnant women despite potential risks.

Category D

There is positive evidence of human fetal risk based on adverse reaction information from investigational or marketing experience or studies in humans, however potential advantages might warrant use of the drug in pregnant girls despite potential risks.

Category X

Studies in animals or humans have demonstrated foetal abnormalities and/or there’s positive proof of human fetal risk based on adverse reaction information from investigational or marketing expertise, and therefore the risks concerned in use of the drug in pregnant girls clearly outweigh potential advantages.


In This Article We Will Talk About The Drugs Safely Used During Pregnancy In general, it’s best to avoid any unnecessary Use Of Drugs early in your pregnancy. During the first trimester, fetal organs develop rapidly, making them extremely vulnerable to the potential risks of drugs.

Prescription Drugs Used In Pregnancy

  • Folic Acid and Vitamin B6
  • Levothyroxine
  • Insulin
  • During 18 and 32 weeks of pregnancy may increase the risk of hyperactivity and behavioral problems in children according to a study published in JAMA Pediatrics.)
  • Methyl dopa, and hydralazine
  • Heparin
  • Some antibiotics namely Amoxycillin, Ampicillin, Cephalosporins, Erythromycin (not estolate)

Drugs Used In Pregnancy For Pain Relief

A cold compress and rest will help alleviate headaches and muscle pain throughout pregnancy, however if you wish further relief, your doctor might recommend acetaminophen. once this drug is used as directed, it is a safe choice. However, it is best to avoid aspirin and nonsteroidal anti-inflammatory drugs (NSAIDS) like ibuprofen and naproxen . Some studies recommend that taking these medications close to conception or in early pregnancy might increase the chance of miscarriage and birth defects.

Drugs Used In Pregnancy For Colds & Allergies

Few women get through 9 months without cold or hypersensitivity reaction symptoms. The safest way to go is to try nondrug remedies: Rest, drink a lot of fluids -particularly warm ones — and use a saline nasal spray to assist relieve stuffiness. the great news is that while a cold will make you miserable, it poses no special risks throughout pregnancy. The flu, however, are often more serious in pregnant ladies, and typically leads to pneumonia. Since influenza shots are safe for both you and baby, it’s knowing get one throughout flu season if you are in your second or third trimester.

If cold or hypersensitivity reaction symptoms interfere together with your ability to eat or sleep, your health care provider could suggest medication, especially if you are past the first trimester. several doctors believe the antihistamine chlorpheniramine  is that the safest choice, because it has been used for several years by pregnant ladies and is not better-known to cause birth defects. unfortunately, very little is known regarding newer medication like loratadine therefore it’s wise to avoid them.

To relieve a cough, doctors usually recommend a drug known as dextromethorphan  However, you should avoid cough product that contain iodine, which might cause doubtless life-threatening thyroid problems within the fetus, still as those that contain high levels of alcohol.

If you need a decongestant, your doctor could recommend a nasal spray that contains oxymetazoline, as a result of only alittle quantity of the drug is absorbed into your system.

Drugs Used In Pregnancy For Digestive Discomforts

Heartburn, constipation, and hemorrhoids are among the foremost common complaints of pregnancy. Luckily, there are many drug-free solutions you’ll use to stop these problems. to move off heartburn, avoid consumption large meals, particularly in the evening, and select smaller, more frequent ones instead. you should additionally steer clear of rich, fried, or spicy foods, which frequently trigger stomach irritation. Sleeping on an incline may stop the contents of your stomach from splashing into your esophagus, causing symptom.

If symptoms persist, your doctor could suggest a safe antacid, like calcium carbonate (Tums). however if additional relief is required, your doctor could recommend sucralfate, usually called carafate, a drug that coats and protects the abdomen lining.

To prevent constipation and also the hemorrhoids that usually follow, drink lots of water and eat fiber-rich foods. Exercise, along with your doctor’s approval, may facilitate to keep constipation unfree. If issues persist, your doctor could recommend a bulk-fiber laxative, like Metamucil or Fiberall. However, you should avoid stimulant laxatives, like castor oil, which may trigger labor. once treating hemorrhoids, use product that contain glycerine or witch hazel, however avoid hydrocortisone, that hasn’t verified to be entirely safe and might be absorbed into your system.
