Sedative-hypnotics are a class of drugs that work on the central nervous system (CNS) to produce a calming or drowsy effect and are often prescribed for insomnia, anxiety, and seizure disorders. They can be classified into three main categories: benzodiazepines, barbiturates, and Z-drugs (non-benzodiazepine hypnotics). Here’s a brief overview of these classes, along with some … Read more
Understanding the action of drugs on the autonomic nervous system (ANS) can be simplified by drawing a comparison with the adrenaline/epinephrine-induced fight, flight, and fright response. This response, also known as the acute stress response, is the body’s physiological reaction to perceived harmful events, attacks, or threats to survival. To better comprehend the role of … Read more
Introduction Mood disorders—including bipolar disorder, schizoaffective disorder, and certain forms of unipolar depression—are chronic and debilitating mental health conditions. Characterized by pathologic mood swings, from manic or hypomanic states to severe depressive episodes, they entail significant morbidity, mortality (through suicide), and a profound impact on patient quality of life and functioning.
