First introduced in the 1930s, sulfonamide drugs, often called sulfa drugs, were the world's first systemic antibacterial agents, revolutionizing infectious disease treatment before the advent of penicillin. While their role as a primary antibacterial has shifted due to resistance, this class of synthetic medications still plays a critical and diverse role in modern medicine.

While dextromethorphan is structurally related to opioids like codeine, it is not classified as a traditional opioid. This crucial detail is key to understanding **what class of opioids is dextromethorphan**, and how this over-the-counter medication works differently from prescription pain relievers.

Tranexamic acid is an antifibrinolytic agent, not an antibiotic, primarily prescribed to prevent and treat excessive bleeding. While its main function involves stabilizing blood clots, some research has explored its potential for indirect antimicrobial effects, contributing to confusion about the question: is tranexamic acid an antibiotic?.

A crucial concept in pharmacology, **antagonist** drugs operate by inhibiting specific receptors in the body rather than activating them. This is key to understanding what drug is considered an antagonist and its diverse medical applications, from reversing overdoses to managing chronic conditions.

First introduced clinically in 1912, phenobarbital is one of the oldest anti-seizure medications still in use. So, **which class is phenobarbital**? It is a long-acting member of the barbiturate drug class, known for its sedative and anticonvulsant properties.

First approved for medical use in the United States in 1956, the medication known by the brand name Stemetil contains the active ingredient prochlorperazine. So, what class of drug is Stemetil? It belongs to the phenothiazine class, a group of drugs with both antiemetic (anti-sickness) and antipsychotic properties.

In pharmacology, agonists are chemical substances that bind to and activate specific receptors on cells, thereby producing a biological response. The therapeutic applications of these drugs are widespread, addressing conditions from chronic pain to metabolic disorders. This article explores what are the most common agonist drugs, their diverse classifications, and their critical roles in modern medicine.

Introduced in the early 1950s, the medication **Phenindione** belongs to a class of drugs called oral anticoagulants, specifically known as Vitamin K antagonists (VKAs). Although once used for preventing blood clots, it is now largely replaced by safer alternatives due to a higher risk of adverse effects.

Medication name confusion is a significant cause of patient safety risks, with reports highlighting the dangers of misinterpreting drug terms. The term "prila" is not a recognized pharmacological classification but is a common point of confusion, often mistaken for the local anesthetic **prilocaine** or the "-pril" suffix that identifies ACE inhibitor drugs used for high blood pressure.
