What are 3 examples of teratogens?

Common teratogens include some medications, recreational drugs, tobacco products, chemicals, alcohol, certain infections, and in some cases, uncontrolled health problems in the birthing parent. Alcohol is a well-known teratogen that can cause harmful effects on the fetus after exposure at any time during pregnancy.

What are 2 examples of teratogens?

Known Teratogens

• angiotensin converting enzyme (ACE) inhibitors, such as Zestril and Prinivil.
• alcohol.
• aminopterin.
• androgens, such as methyltestosterone (Android)
• busulfan (Myleran)
• carbamazepine (Tegretol)
• chlorobiphenyls.
• cocaine.

What are teratogenic substances?

A teratogen is any agent that causes an abnormality following fetal exposure during pregnancy. Teratogens are usually discovered after an increased prevalence of a particular birth defect. For example, in the early 1960’s, a drug known as thalidomide was used to treat morning sickness.

What are the example of teratogenic drugs?

Teratogenic drugs and birth defects

• ACE (angiotensin converting enzyme) inhibitors.
• angiotensin II antagonist.
• isotretinoin (an acne drug)
• alcohol.
• cocaine.
• high doses of vitamin A.
• lithium.
• male hormones.

What are 4 teratogens?

Teratogens are classified into four types: physical agents, metabolic conditions, infection, and finally, drugs and chemicals.

Is caffeine a teratogen?

In humans, caffeine does not present any teratogenic risk. The increased risk of the most common congenital malformations entailed by moderate consumption of caffeine is very slight.

What is the most common teratogen?

Alcohol: One of the most commonly used teratogens is alcohol, and because half of all pregnancies in the United States are unplanned, it is recommended that women of child-bearing age take great caution against drinking alcohol when not using birth control or when pregnant (CDC, 2005).

What is the most commonly used teratogen?

Are there any drugs that are Teratogenic agents?

Many prescribed drugs can act as teratogens including some anticonvulsant agents, lithium, androgens, retinoids, and misoprostol. Teratogenic agents may affect development of the embryo and fetus and upon exposure by a pregnant woman can cause birth defects, fetal loss or abnormal growth and development.

Which is the best definition of a teratogenic substance?

What is a teratogenic substance? A teratogenic substance, or teratogen, are chemicals that affects the normal growth and development of a fetus. These abnormalities or malformation can even affect the viability of the pregnancy. It does not only apply to pharmaceutical drugs.

How many babies are affected by teratogenic drugs?

Medical science cannot always predict how exposure to a teratogenic drug will affect a fetus. The potential for harm depends on a range of factors including: other factors, such as maternal diet or illness. The risk of a birth defect for any baby is about four per cent, regardless of the circumstances during pregnancy.

How are teratogens and prenatal substance abuse related?

The types or severity of abnormalities caused by a teratogenic agent is also dependent on the genetic susceptibilities carried by the mother and fetus. For example, variation in maternal metabolism of a particular drug will determine what metabolites the fetus is exposed to and the duration of exposure.
