Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Drug Toxicity: Dose-Dependent Reactions

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Drug toxicity: Idiosyncratic Reactions

Drug toxicity: Idiosyncratic Reactions

Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

Genomic Imprinting and Inheritance

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Drug Toxicity: Overview

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Drug Regulation

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Summary

This summary is machine-generated.

Thalidomide, a hypnotic drug, is linked to severe birth defects like phocomelia when taken early in pregnancy. This highlights the critical need for caution with new medications during gestation.

Background:

Phocomelia (flipper-like limbs) is a rare congenital malformation.
Recent reports link phocomelia and other birth defects to thalidomide use in early pregnancy across multiple countries.

Purpose of the Study:

To present two additional cases of infants with phocomelia, amelia, and alimentary abnormalities.
To investigate the potential teratogenic effects of thalidomide and related glutarimide compounds.

Main Methods:

Clinical case reporting of two infants with severe congenital malformations.
Review of patient history regarding drug administration during pregnancy.
Chemical structure analysis of thalidomide and related glutarimides.

Main Results:

Both infants presented with phocomelia, amelia, and alimentary abnormalities.
Mothers reported thalidomide administration early in pregnancy (5-8 weeks post-LMP) for several weeks.
Thalidomide (alpha-phthalimido glutarimide) shares chemical similarities with other glutarimides.

Conclusions:

Thalidomide is strongly implicated as a teratogen causing severe limb and other malformations.
Related glutarimide compounds and their metabolites may also pose teratogenic risks.
Extreme caution is advised when prescribing new drugs, particularly during early pregnancy.
