Classification Based on Duration of Action Rapid-Acting: Immediate effect (e.g., insulin, nitroglycerin). Intermediate-Acting: Moderate duration (e.g., certain sedatives). Long-Acting: Sustained effect (e.g., long-acting antihypertensives).
l Context of Crude Drug Classification Historically, the classification of crude drugs has evolved from simple morphological categorizations to sophisticated systems integrating phytochemical, pharmacological, and anatomical data. Ancient civilizations such as the Egyptians, Greeks, and Chinese
