Which benzodiazepine is safe during pregnancy?
The available literature suggests that it is safe to take diazepam during pregnancy but not during lactation because it can cause lethargy, sedation, and weight loss in infants. The use of chlordiazepoxide during pregnancy and lactation seems to be safe.
Which drug is a benzodiazepine receptor antagonist?
Flumazenil is a recently discovered pharmacologic antagonist of the CNS effects of benzodiazepines. It acts by binding CNS benzodiazepine receptors and competitively blocking benzodiazepine activation of inhibitory GABAergic synapses.
What do benzodiazepines do to GABA receptors?
Benzodiazepines increase the frequency of chloride channel influx which hyperpolarizes the GABA receptor, resulting in increased inhibitory postsynaptic potential.
What is the safest anxiety medication during pregnancy?
While benzodiazepines are category D, long-term anxiety medications like Prozac and Zoloft are often described as “probably safe.” Tricyclic antidepressants and buspirone may be safe during pregnancy as well.
Can I take Klonopin while pregnant?
In general, using Klonopin while you are pregnant should be avoided. However, this may be difficult for some women who need the medication to function in their daily lives. If you are currently using Klonopin and become pregnant, do not adjust your treatment schedule before speaking with your doctor.
Which is an example of specific benzodiazepine antagonist?
Flumazenil, a specific benzodiazepine antagonist, reverses the life-threatening effects of a benzodiazepine overdose.
Is Diazepam an agonist or antagonist?
A central nervous system depressant used to induce drowsiness or sleep or to reduce psychological excitement or anxiety. A substance that does not act as agonist or antagonist but does affect the gamma-aminobutyric acid receptor-ionophore complex….CHEBI:49575 – diazepam.

Why benzodiazepine is preferred over barbiturates?
Benzodiazepines and the newer non-benzodiazepine hypnotics are now preferred over barbiturates for most of these clinical uses because they have a wider therapeutic index, tolerance develops more slowly, and their liability for abuse is lower than that of the barbiturates.
Why are barbiturates no longer used?
Medical uses The original use of barbiturates as sedative/hypnotics is no longer recommended because of their adverse reactions and risk of dependence.
How do Benzos act on GABA?
Benzodiazepines produce their effects by enhancing the binding of GABA to its receptor. GABA activates the chloride ion channel, allowing chloride ions to enter the neuron. The flow of chloride ions into the neuron hyperpolarizes and inhibits the neuron.
Do benzodiazepines potentiate GABA?
Benzodiazepines (BZs) produce most, if not all, of their pharmacological actions by specifically enhancing the effects of endogenous and exogenous GABA that are mediated by GABAA receptors.
