Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
An Overview of Psychoactive Drugs01:28

An Overview of Psychoactive Drugs

Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...
Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
Drugs Affecting Neurotransmitter Synthesis01:29

Drugs Affecting Neurotransmitter Synthesis

Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
Drug Therapy01:28

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Area of Science:

  • Endocrinology
  • Clinical Pharmacology

Background:

  • The hypothalamo-pituitary-adrenal (HPA) axis regulates cortisol production.
  • Drug-induced alterations in HPA function can mimic or mask endocrine disorders.
  • Accurate diagnosis of cortisol imbalances requires understanding potential drug interferences.

Purpose of the Study:

  • To review common medications affecting HPA axis function.
  • To detail the impact of these drugs on relevant laboratory parameters.
  • To provide practical guidance for clinicians managing patients with suspected cortisol abnormalities.

Main Methods:

  • Literature review of widely used drugs and their effects on HPA axis.
  • Analysis of drug-induced changes in cortisol and related biomarker assays.
  • Synthesis of information for clinical application.

Main Results:

  • Identified key drug classes interfering with HPA axis.
  • Described specific mechanisms of interference (e.g., receptor binding, enzyme inhibition).
  • Highlighted common laboratory test abnormalities caused by these drugs.

Conclusions:

  • Clinicians must consider drug history when evaluating HPA axis function.
  • Awareness of drug interferences is crucial for accurate diagnosis of hypo- or hypercortisolemia.
  • This review serves as a resource for optimizing diagnostic testing in patients on medication.
