Why do we need to classify drugs in different ways ? |
| Answer» Drugs have been classified in different ways depending (i) upon their pharmacological effect, (ii) upon their action on a particular biochemical process,(iii) on the basis of their chemical structure and (iv) basis of molecular targets. Each classification has its own usefulness. Classification on the basis of pharmacological effect is useful for doctors because it provides them the whole range of drugs available for the treatment of a particular disease Classification on the basis of action on a particular biochemical process is useful for choosing the correct lead compound for designing the synthesis of a desired drug Classification on the basis of chemical structure helps us to design the synthesis of a number of structurally similar compounds having different substituents and then choosing the drug having least toxicity. Classification on the basis of molecular targets is useful for medicinal chemists so that they can design a drug which is most effective for a particular receptor site | |
| 91. |
Why do we need to classify the drug in different ways? |
|
Answer» 1)By knowing the pharmacological effect it makes easy for doctors. 2)Antacid can be used in case of excessive acidity in stomach. |
|
| 92. |
Why do we need to classify drugs in different ways ? |
|
Answer» The reason for the drug’s classification is as follows: (i) The pharmacological impact is based on: To physicians this definition is helpful. It provides a whole array of drugs to classify drugs to different diseases. (ii) Based on action on the drugs: This is based on a drug’s action on a specific biochemical process. (iii) Building on chemical structure: The range of drugs that share common structural characteristics and have similar pharmacological activty (iv) Building on molecular objectives: Many medications have the same action function on targets. In such cases this distinction is useful. |

Synthetic detergents have advantage over usual soaps as far as cleansing power is concerned. But use of synthetic detergents over a long time creates environmental pollution. How can the pollution caused by synthetic detergents be minimised? Classify the detergents according to their chemical nature. |
| Answer» Pollution caused by synthetic detergents and its minimisation: Detergents having highly branched hydrocarbon chains are not biodegradable. The reason being that side-chains stop bacteria from attacking and breaking the chains. . Such detergents are therefore accumulated in rivers and ponds and make the water polluted. Since unbranched hydrocarbon chains are easily attacked by bacteria, therefore, in most of the detergents used these days, the branching of the hydrocarbon chain is kept to a minimum so that detergents become easily biodegradable and hence pollution is prevented. | |

Sodium salts of some acids are very useful as food preservatives. Suggest a few such acids ? |
|
Answer» A preservative is naturally occuring or sunthetically produced substance that is added to food to prevent decomposition by microbial growth or by undesirable chemical changes. Sodium salts of same acids are very useful as food preservatives. Some example of such acid are as follows (i) Benzoic acid in the form of its sodium salt, constitues one of the most common food preservative, Sodium benzoats is a common preservative in acid or acidified foods such as fruit, juices, pickles etc.Yeasts are inhibited by benzoate to a greater extent than are moulds and bacteria. (ii) Sorbic acid and its salts (sodium, potassium and calcium) also have presservative acitivities bu the applications of sodium sorbate `C_(6)H_(7)NaO_(2)` are limited compared to that for potassium drinks. (iii) Sodium erythorbate `C_(6)H_(7)NaO_(6)` is a food additive used predominate iin meats, popultry and soft drinks (iv) Sodium propanoate `Na(C_(2)H_(5)COO)` is used in bakery products as mold inhibitor. |
