You must have seen a difference in the prescription of two unhealthy people which is prescribed by a doctor. Whenever you feel uneasy or fall sick, you should consult your doctor first, then he will prescribe you some medicine based on the symptoms you have. A small kid suffering from fever has been prescribed another medicine and a young man suffering the same is prescribed another. Why this happens, have you ever asked to your doctor. This is due to the classification of drugs based on the nature and symptoms of human activity. Medicines also have a wide range. A lot of chemicals are required to develop a single medicine. Scientists work hard to develop this and are then tested properly before it comes to use.
Let us study the classification of drugs and their importance.
Table of content:
Drugs or medicines are chemicals that produce changes in the functional and or mental nature of animals. It is used to diagnose or prevent, cure diseases and to alleviate pain. Drugs are classified in terms of their chemical structure mode of action, physiological effect and mechanism of action
Drugs are man-made chemicals with specific functions. These compounds are specifically formulated and manufactured to treat a variety of disorders and diseases that impact the human body. To locate cures for all types of ailments, a medical student needs to have extensive knowledge of the numerous pharmaceutical medications and their classifications.
Drugs are chemical substances that, when consumed, change the way the body functions, either physically or psychologically, or both. Low molecular weight drugs (about 150 amu to 500 amu) interact with macromolecule targets and induce appropriate biological responses.
An analgesic, for example, relieves pain while an anti-inflammatory medicine lowers body inflammation. Drugs can thus be categorised according to their pharmacological action.
Based on their pharmacological effects on the body, drugs are divided into distinct classes. Let's take a closer look at each one individually.
Drugs with Neurological Activity: Neurologically active drugs change the way a message travels from the nerve to the receptor. Tranquillizers and analgesics are the two categories.
To answer this question, we must first consider the subject of purpose - particularly, what is the purpose of medicine and a drug?
A medicine's goal is to prevent, relieve, or cure a symptom, ailment, or disease state. In other words, a medicine's objective is benign; it's a product created and regulated to have a beneficial medical effect on a patient.
A drug also has a lot of different ingredients. In addition to the active component, medicines also contain excipients, which aid in the formulation and efficacy of the medication for the patient

Q2. Among which of the following is a narcotic analgesic?
Codeine is a pain reliever that is used to treat mild to severe pain. It belongs to the class of drugs known as narcotic analgesics (pain medicines). To treat pain, this drug operates on the central nervous system (CNS).
Q3. Terfenadine is a class of
Terfenadine is an antihistamine that is used to treat allergy disorders. It is a bioprecursor prodrug. Sneezing, runny nose, itching and watering of the eyes, and other allergy symptoms are all prevented by antihistamines.
Q4. Aminoglycosides come under the branch of
a. Bacteriostatic antibiotics
b. Bactericidal antibiotics
c. Broad-spectrum antibiotics
d. Limited spectrum antibiotics
Antibiotics such as aminoglycosides are used to treat serious infections caused by bacteria that proliferate rapidly or are difficult to treat. Bactericidal antibiotics are aminoglycoside antibiotics that destroy bacteria directly.
Q1. How did the early man use natural substances as medicines?
Answer: Early man used a variety of plants or parts of plants to treat ailments without understanding the chemical components that caused them. The bark of the willow tree, for example, was once used to treat pain (as an analgesic). Its bark was later discovered to contain 2-hydroxy benzoic acid, which is related to acetyl salicylic acid (also known as aspirin).
Q2. Can we use dyes to kill microorganisms?
Answer: Microorganisms can be killed by certain colours. These colours were among the first to be employed as antiseptics. Acriflavine (a yellow coloured dye), mercurochrome (a red coloured dye), and methylene blue are among examples (a blue coloured dye). Antiseptics are still made with these colours.
Q3. Is phenol a disinfectant or an antiseptic?
Answer: It's worth noting that a 0.2 percent aqueous phenol solution is used as an antiseptic by producing. In low doses, it is safe to use on living tissues (less than 0.2 percent).
When phenol concentrations are excessive, it can cause tissue damage. As a result, phenol is employed as a disinfectant at larger concentrations (1 percent or more).
Q4.What do you mean by Downer drug?
Answer: Downer slang phrase refers to CNS depressants, which are drugs that cause sedation by decreasing the transmission and reception of messages between the central nervous system and the brain. They make the person feel drowsy or relaxed, and they are often very successful at reducing pain. Downers, the polar opposites of uppers, reduce attentiveness and focus.
