1. What are the Ways of Classifying Drugs? Why is the Classification Done?
Drugs are classified in different ways to distinguish based on pharmacological effect, biochemical process or chemical structure. They are also differentiated to understand molecular targets.
The classification is done for the following reasons:
Category based on pharmacological helps doctors to remain updated drugs available in market
Classification based biochemical process eases out the process of choosing the exact amalgam of a drug.
Chemical structure helps to plan structurally analogous compound having different substituents to choose the least toxic drug.
2. What Type of Drugs are Needed to Cure Depression?
Depression can be troublesome for many as it causes lack of sleep, mood swings and even suicidal tendency. Usually, the lowering of noradrenaline, drugs like tranquiliser, neurotransmitter and noradrenaline can be used.
These drugs have a proportional level of enzymes that can neutralise the level of noradrenaline in a patient. When the drug is injected, the noradrenaline gradually starts to metabolise, making the receptor active. This situation can remain for a longer time, thereby reducing the level of depression and stress. Drugs like iproniazid and phenelzine can also be beneficial in this case.
3. What is the Primary Difference Between Antiseptics and Disinfectants?
Many times a solution or composition can work as an antiseptic as well as a disinfectant. The composition ratio can make the potential difference which is crucial. A solution has 0.2 per cent of phenol which is antiseptic while 1 per cent can be disinfectant. Another substance Chlorine has a concentration of 0.2 to 0.4 ppm, which makes it compatible with cleaning water.
An antiseptic does not harm the living tissue making it safe for the skin. In contrast, a disinfectant can burn or cause severe damage to body parts. Ideally, antiseptics are used for wounds dressing, treatment of diseased skin and ulcers, etc. While cleaning floors, toilets, drains, instruments etc. are the usage of disinfectant.
4. How is chemistry used in everyday life?
Every aspect of our life has a direct or indirect influence of chemistry in it. Chemistry is a crucial part of our day to day lives, from the air we breathe, the food we eat, the house we live in to the emotions that we experience. The medicines we consume when we are sick are prepared with the help of chemistry. The natural phenomenon around us, such as digestion, discoloration of leaves, and floating of ice on the water are all based on the principles of chemistry.
5. How is soap useful for human beings in reference to Chapter 16- Chemistry in Everyday Life?
Soaps are extremely important in our daily lives as they help us keep our bodies clean. With the aid of chemistry, the cleanliness function of soaps can be explained. When we wash our hands with soap, the soap molecules bind to the dirt and the oil from our hands. When we wash our hands with water, these dirt and oil particles also get washed away, along with the soap and our hands become clean and germ-free.
6. What problems can chemistry solve?
Chemistry can solve a lot of pressing challenges and problems. Chemistry can help manufacture sustainable and eco-friendly materials. It helps us understand the properties and the features of elements and compounds, metals and non-metals around us. It provides a lot of scope for research and development. Chemistry can help devise alternate sources of energy. It is chemistry that has helped humans to harness electricity and has enabled optimum utilization of various forms of energy.
7. How is chemistry used in medicine?
The branch of chemistry that helps to create medicines is called Medicinal Chemistry. The medicines are created after extensive research by chemists. The entire process of research, design and development of all medicines is done with the aid of chemistry. Chemistry also has a huge role in creating surgery equipment and medicines through several techniques involving the application of chemistry concepts. For instance, pharmaceutical drugs, blood samples for laboratory testing and blood glucose testing devices demonstrate the use of chemistry in medicine.
