    As phencyclidine hydrochloride (PCP) has become one of the more frequently abused drugs in the United States, there has been increasing interest in its effect on the fetus and neonate of the pregnant abuser. Two groups of women enrolled in a comprehensive perinatal addiction program were studied: 7 women abused PCP prior to and during pregnancy, and these women were compared to a group of 27 drug-free women. No differences between the two groups were seen in maternal age, gravidity, gestational age or Apgar scores. At birth, there was no difference in birth weight, length, or head circumference between the two groups of neonates. The most characteristic features of the PCP-exposed infants were the sudden outbursts of agitation and rapid changes in level of consciousness, similar to responses described in adults intoxicated with PCP. Scores on the Brazelton Neonatal Behavioral Assessment Scale revealed a significant increase in lability of states and poor consolability in PCP-exposed infants. 3-month scores on the Bayley Scales of Infant Development revealed no significant difference between the two groups of infants.

    Factors Affecting Drug Response: Overview

    When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

    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...

    Parenteral Anesthetics: Overview

    Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

    Nonlinear 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.

    Pharmacokinetics 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...

    Pharmacokinetics in Pediatric Patients: Drug Distribution

    Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
