Which Of The Following Are Drugs Derived From Animal Substances?

Drugs Derived from Plants, Minerals and Animals

Article shared by :

Rough drugs are derived from the natural sources e.thousand. from plants, minerals and animals. These drugs are used in the treatment of diverse diseases and ailments of human. For a systemic and scientific study of rough drugs it is very essential to classify all the drugs in proper organisation crude drugs can exist arranged in different classes.

one. Alphabetical Classification :

In this nomenclature crude drugs are arranged alphabetically either in Latin proper noun or in English proper name. The post-obit books adopt this method of classification.

1. British Pharmacopoeia (English title)

2. British Pharmaceutical Codex (English title)

3. British Herbal Pharmacopoeia (English title)

iv. Indian Pharmacopoeia (English title)

5. European Pharmacopoeia (Latin title)

6. Pharmacopoeia International (Latin title)

Alphabetical Classification

2. Taxonomical Classification :

This is a purely botanical classification. It is based on phylogenetic similarities of plants. In this system rough drugs are arranged in a group according to their division, form, order, family, genus and species. This system gives in detail an platonic about the whole found but it is non significant because in most of the cases simply one function of plant is used as drug. The whole institute is rarely used as drug. For example Cinnamon bark. Cinchona bark, Nux vomica seed, etc. This system does non give any idea about the chemical constituents and pharmacological activity of crude drugs.

Taxonomical Classification

3. Morphological Nomenclature:

In this blazon of classification crude drugs are arranged in diverse groups according to the part of plant (for example leaves, fruits, flowers, bark, etc.) used as drug. When a drug represents a cellular construction of the plant, it is known equally organized drug merely when a drug does not represents part of plant or whatsoever cellular construction of the establish, it is known as an unorganized drug.

Classification of organized and unorganised drugs

4. Pharmacological Nomenclature :

In this type of classification, drugs are grouped according to pharmacological action of their most of import constituent. Here drugs having like action are kept together. It may be possible that the same drug having to unlike types of pharmacological actions can exist allocate separately in two groups east.g. Cinchona- antimalarial and bitter, Nux-vomica – Stimulant and bitter. This does not give whatsoever indication nearly morphological and chemical nature of drugs. Examples:

Pharmacological Classification

5. Chemical Classification :

The institute s and animals synthesize a big number of chemical like carbohydrate, protein, fat, alkaloids, glycosides, volatile oils, etc. in these system drugs are classify according to their master category. This arrangement is very useful for the study of rough drugs considering it gives logical reasoning for the biological activity.
