Study Notes
Definition of Drugs
- Drugs are chemical constituents obtained from natural herbal sources or synthetic sources.
- In India, drugs are defined under the Drugs and Cosmetics Act as substances intended for internal or external use in humans or animals for diagnosis, treatment, mitigation, or prevention of diseases.
Importance of Classification
- Classification is necessary for drugs because they are not similar in many aspects.
- If not classified, drug identification and drug safety become challenging.
Classification Systems
Alphabetical Classification
- Arranges crude drugs in alphabetical order.
- Demerits: lacks relationship with previous drug entries.
Morphological Classification
- Arranges crude drugs based on plant parts (e.g., leaf, bark, flower, fruit, seed, etc.).
- Divided into two categories:
- Organised drugs: obtained directly from plant parts and contain cellular tissue.
- Unorganised drugs: prepared from plants through intermediate physical processes and do not contain cellular plant tissue.
- Merits: identification and detection of adulteration are easier, and practical study is more effective.
- Demerits: chemical constituents have no correlation with therapeutic action, and repetition of drugs or plants may appear.
Taxonomical/Biological Classification
- Classifies crude drugs based on their kingdom, subkingdom, division, class, order, family, genus, and species.
- Merits: evolutionary development is understood.
- Demerits: fails to recognize organized and unorganized forms of crude drugs, and chemical nature and therapeutic significance are not included.
Chemical Classification
- Classifies crude drugs based on their chemical constituents.
- Merits: phytochemical studies are well performed.
- Demerits: confusion occurs when a drug contains many compounds belonging to different groups.
