Prescription drugs
can be grouped into different classification systems. A commonly used system developed in 1959 is called the AHFS (American Hospital Formulary Service) Pharmacologic-Therapeutic Classification System. Drugs are classified in a four-tier system; there are 30 primary classifications and hundreds of sub-classifications. Prescription drugs are grouped according to similar action and chemical structure.
Anti-Infective Agents
Anti-infective agents are a commonly used type of prescription drug. Drugs in this class include antibiotics, anti-fungals and anti-virals.
Cardiovascular Drugs
Cardiovascular drugs regulate heart rhythm, control blood pressure and lower cholesterol. There are nine secondary classifications in this group.
Central Nervous System Agents
Many central nervous system agents require additional governmental regulation due to the potential for abuse. Opioids, barbiturates, sedatives and hypnotics fall under this classification.
Respiratory Tract Agents
Respiratory tract agents are used to treat various respiratory illnesses. Antihistamines and bronchodilators are in this classification.
Miscellaneous Therapeutic Agents
Prescription drugs that do not fit into any of the other 29 primary classifications are grouped as miscellaneous therapeutic agents. Sub-classes include antidotes, anti-gout preparations, anti-Parkinsonian agents and immunosuppressive agents.
