Introduction/Overview Propofol is a short-acting intravenous anesthetic agent that has become a cornerstone of modern anesthesia and critical care practice. Since its clinical introduction in the late 1980s, it has largely supplanted older induction agents such as thiopental due to its favorable pharmacokinetic profile and rapid recovery characteristics. The drug is employed ubiquitously across diverse … Read more
1. Introduction/Overview Morphine represents the prototypical opioid analgesic and serves as the benchmark against which all other opioids are compared. Isolated from the opium poppy Papaver somniferum in the early 19th century, its introduction into medical practice marked a pivotal advancement in the management of acute and chronic severe pain. As a naturally occurring phenanthrene … Read more
Introduction Migraine is a debilitating primary headache disorder characterized by episodic attacks of throbbing or pulsating head pain, often accompanied by photophobia, phonophobia, nausea, and in some cases, aura phenomena. Although once perceived purely as a vascular headache, recent advances in neuroscience underscore the neurovascular and inflammatory underpinnings of migraine. The complexity of its pathogenesis, … Read more
Introduction Epilepsy, a chronic neurological disorder characterized by recurrent seizures, affects millions of individuals worldwide (Katzung, 2020). While the underlying pathophysiology varies, epilepsy generally arises from aberrant, hypersynchronous neuronal discharges in the brain. Such episodes can manifest differently, ranging from brief lapses in awareness to severe convulsions. Pharmacotherapy remains the primary approach to controlling or reducing seizure … Read more
Introduction Sedative-hypnotics are a class of medications primarily utilized to induce sedation (calming) or hypnosis (sleep). These central nervous system (CNS) depressants work by enhancing inhibitory neurotransmission within the brain, thereby diminishing alertness, reducing anxiety, and facilitating the onset or maintenance of sleep. The broad category of sedative-hypnotics encompasses a variety of drug families, including benzodiazepines, barbiturates, non-benzodiazepine “Z-drugs”, and several others … Read more
Introduction Antidepressant medications are a cornerstone of modern psychiatric care, offering relief and long-term stabilization for individuals experiencing major depressive disorder, anxiety disorders, and other related conditions. These drugs emerged as a groundbreaking treatment alternative to earlier therapies, such as electroconvulsive therapy and long-term institutionalization. Over time, the pharmacology of antidepressants has become more refined, with newer … Read more
Introduction Aspirin—chemically known as acetylsalicylic acid—is among the most widely used medications across the globe. Renowned for its analgesic, antipyretic, anti-inflammatory, and, at low doses, antithrombotic actions, aspirin’s versatility has made it a mainstay in clinical practice for well over a century. Discovered in the late 19th century, aspirin’s enduring role owes to its capacity to provide effective pain relief, reduce … Read more
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are among the most widely used medications worldwide, offering relief from pain, inflammation, and fever for a myriad of conditions. Their popularity stems from their effectiveness, accessibility (many are available over the counter), and wide safety margin when used appropriately. From mild headaches to chronic inflammatory diseases such as rheumatoid arthritis, … Read more
Scope and Definition Anxiolytics are a class of pharmacological agents administered to treat pathological anxiety—a set of disorders characterized by excessive and unmanageable worry or fear. Anxiety may be generalized (GAD), situational (phobias), episodic (panic disorder), obsessive-compulsive (OCD), or post-traumatic (PTSD). Clinical management is driven by agent efficacy, risk profile, presence of comorbidities, and short- versus … Read more
Introduction to Ketamine Ketamine, a compound initially synthesized in 1962, marked a significant milestone in anesthetic medicine. Developed as an alternative to phencyclidine (PCP), ketamine was first used in clinical settings during the Vietnam War for its anesthetic properties. Over the years, its application has expanded beyond anesthesia, gaining attention for its potential in treating … Read more
