Summary
Pregnancy alters how the body processes antidepressants, affecting drug levels in pregnant women and newborns. Dose adjustments may be necessary during pregnancy for safe and effective treatment.
Area of Science:
- Pharmacology
- Biochemistry
- Obstetrics
Context:
- Pregnancy significantly impacts drug metabolism and disposition.
- Understanding drug pharmacokinetics during gestation is crucial for maternal and fetal health.
Purpose:
- To investigate the influence of pregnancy on antidepressant pharmacokinetics.
- To determine how cytochrome P-450 enzymes affect antidepressant bioconversion during pregnancy.
- To analyze antidepressant concentrations in maternal and neonatal blood plasma.
Summary:
- Pregnancy alters cytochrome P-450 dependent bioconversion and pharmacokinetics of antidepressants.
- Specific bioconversion characteristics of certain antidepressants were identified.
- Pharmacokinetic data revealed dynamics of antidepressant blood plasma concentrations in pregnant women.
- The study discusses the need for adjusting daily antidepressant doses during pregnancy.
- Data on the ratio of neonatal to maternal plasma antidepressant concentrations and the role of transporter proteins in transplacental transfer are presented.
Impact:
- Provides essential data for optimizing antidepressant therapy in pregnant individuals.
- Highlights the importance of considering physiological changes during pregnancy for drug management.
- Informs clinical practice regarding safe antidepressant use and dosing during pregnancy and for newborns.

01:23Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance
The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

01:25Antidepressant Drugs: Overview
Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...
01:23Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
01:28Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...
01:23Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
01:25Pharmacokinetics: Drug–Drug Interactions
Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...
