Things To Remember
- The use of chemicals for the treatment of humans is known as chemotherapy. Generally used for cancer patients.
- Proteins that perform the role of biological catalysts in the body are called enzymes.
- Some drugs do not bind to the enzyme’s active site. These bind to a different site of enzyme which is called the allosteric site.
- Drugs that bind to the receptor site and inhibit its natural function are called antagonists.
Sample Questions
Ques 1. Why do we need to classify drugs in different ways? (2 Marks)
Ans. The importance of drug classifications cannot be overstated. They help in the prevention of serious side effects and drug interactions. They aid in the breakdown and utilisation of the drug by your body. Many treatment decisions are aided by them. This classification is based on how medications interact with macromolecules. Carbohydrates, lipids, proteins, nucleic acids, and other biomolecules can all be targets for drugs. Drugs with similar structures react similarly to biomolecules of this type. This is chemists' preferred way of classification.
Ques 2. Explain the term, target molecules or drug targets as used in medicinal chemistry. (2 Marks)
Ans. Target molecules or therapeutic targets are important molecules (such as carbohydrates, proteins, and nucleic acids) that are engaged in certain metabolic pathways that contribute to certain disorders in medicinal chemistry. When drug molecules bind to the active sites, they inhibit the target molecules.
Ques 3. Why should not medicines be taken without consulting doctors? (2 Marks)
Ans. A medication can bind to multiple receptor sites at the same time. As a result, a drug may be harmful to certain receptor sites. As a result, drugs in such situations may be poisonous. Taking the medicine without first getting a correct diagnosis could hide signs of an underlying illness that is worsening. It's possible that the dose is incorrect for your body size or weight. To avoid side effects, you may need to take other medications alongside it.
Ques 4. Define the term chemotherapy. (2 Marks)
Ans. Chemotherapy is a medicinal treatment that uses strong chemicals to kill your body's fast-growing cells. Chemotherapy is most commonly used to treat cancer because cancer cells grow and proliferate significantly faster than the rest of the body's cells. Chemotherapy medications come in a variety of forms.
Ques 5. While antacids and antiallergic drugs interfere with the function of histamines, why do these not interfere with the function of each other? (2 Marks)
Ans. Specific medications have an effect on specific receptors. Anti-allergic medicines and antacids target separate receptors. This is why antacids and anti-allergic medicines do not interact with one another's functions but do interfere with histamines' functions.
Ques 6. What is meant by the term ‘broad-spectrum antibiotics? (2 Marks)
Ans. A broad-spectrum antibiotic is one that works against both Gram-positive and Gram-negative bacteria, as well as any antibiotic that works against a large range of disease-causing microorganisms. Azithromycin, amoxicillin, tetracycline, and quinolones are examples of broad-spectrum antibiotics. Glycopeptides and bacitracin are the most popular narrow-spectrum antibiotics used to treat Gram-positive infections, while polymyxins are used to treat Gram-negative bacterial infections.
Ques 7. How do antiseptics differ from disinfectants? (2 Marks)
Ans. Antiseptics, on the other hand, are used on live tissues like wounds, cuts, ulcers, and infected skin surfaces, whereas disinfectants are used on inanimate items like floors, drainage systems, equipment, and so on. Disinfectants are toxic to live organisms. An example of a strong antiseptic is iodine.
Ques 8. What is the tincture of iodine? (2 Marks)
Ans. A tincture of iodine is a weak or dilute solution of elemental iodine in water and alcohol with sodium iodide or potassium iodide. The solution is largely made up of ethanol. Iodine tincture is another name for iodine tincture. It's for minor cuts, scrapes, and wounds.
Ques 9. Why is the use of aspartame limited to cold foods and drinks? (2 Marks)
Ans. Because aspartame is unstable at cooking temperatures, it is only used in cold foods and soft drinks. In comparison to other sweeteners, aspartame is inappropriate for baking and cooking at high temperatures because it breaks down and loses sweetness when heated. It does not heat well, so it cannot be used as a baking or cooking substitute. It's frequently used to sweeten hot drinks like tea and coffee. The Food Standards Agency (FSA) recommends 40 milligrams of aspartame per kilogram of body weight per day as an Acceptable Daily Intake (ADI).
Ques 10. Define Drugs. (2 Marks)
Ans. Drugs are chemicals of low molecular masses which interact with macromolecular targets and produce a biological response.
Ques 11. What are antagonists and agonists? (2 Marks)
Ans. Drugs that bind to the receptor site & inhibit its natural action are called antagonists whereas the drugs that mimic the natural messenger by switching on the receptor are agonists.
Ques 12. Metal hydroxides are used as antacids instead of metal hydrogen carbonates. Why? (2 Marks)
Ans. The stomach produces more acid if there are excessive hydrogen carbonates. Therefore metal hydroxides are better antacids as they are insoluble & do not increase pH above neutrality.
Ques 13. What are antihistamines? Give two examples. (2 Marks)
Ans. Antihistamines prevent the interaction of histamine with the receptors present in the stomach wall e.g. Ranitidine, Soldane etc.
Ques 14. Give two examples of barbiturates. (2 Marks)
Ans. Veronal, Amytal, Nebutal, Liminal & Seconal are some of examples of barbiturates.
Ques 15. What are analgesics? (2 Marks)
