100 to 500 units

Question 2

Analgesics

Answer 2

Painkilling effect

Question 3

Antiseptics

Answer 3

Killer or arrest the growth of organisms

Question 4

On the basis of drug action

Answer 4

All anti histamines inhibit the action of compound and histamine which causes inflammation in the body

Question 5

On the basis of chemical structure

Answer 5

Sulfonimize have common structure features same pharmalogical activity

Question 6

On the basis of molecular targets

Answer 6

Drugs usually interact with biomolecule such as carbohydrates lipids proteins and nucleic acids these are called target molecules or drug targets

Question 7

Enzymes

Answer 7

Proteins which perform the role of biological catalyst in the body are called enzymes

Question 8

Receptors

Answer 8

Proteins which are crucial to communication system in the body

Question 9

Carrier proteins

Answer 9

The carry polar molecules across the cell membrane

Question 10

Two major functions of enzymes

Answer 10

First hold substrate for a chemical reaction active sites of enzymes for the substrate molecule in a suitable position so that it can be attacked by the reagent effectively second thing is to provide the functional group that will attacked the substrate and carry out chemical reaction this is catalytic action of enzymes

Question 11

Drug enzyme interaction and enzyme inhibitors

Answer 11

Drug stop any of the above activities of enzymes these can block the binding side of the enzyme and prevent the binding of substate or can inhibit the catalytic activity of the enzyme such drugs are called enzyme inhibitors

Question 12

Two types of enzyme inhibitors

Answer 12

First one is competitive inhibitors which come in place of the substrate second one is which bind to allosteric site and change the shape of the active site

Question 13

Receptors drug targets

Answer 13

Body communication system. present in cell membrane. small part processing active site projects out the surface and membrane and opens in the outside region of the cell. message between two neurons are neurone to muscle receive ad binding sites of receptor proteins. Transfer message into sell without entering the cell.

Question 14

Agonist and antagonist

Answer 14

Agonist drug that mimic the natural messenger by switching on receptor useful while lack of chemical messenger. Antagonist drugs that bind to receptor site and inhibit natural function useful when blocking of messages

Question 15

Antacids

Answer 15

Reduces or neutralizers acidity example baking soda metal hydroxide

Question 16

What does histamine do and what is used to prevent it

Answer 16

Histamine stimulance the secretion of pepsin and HCL in the stomach the drug cimetidine(tagmet) was designed to prevent the interaction of histamine with receptors present in the stomach wall test result in the release of lesser amount of acid

Question 17

Largest selling antacid

Answer 17

Zantac-ranitidine

Question 18

Examples of antihistamines

Answer 18

Bromopheniramine- dimetapp(BD)

Terfenadine-Seldane (TS)

Question 19

Tranquilizers

Answer 19

Using treatment of stress mild or even severe mental diseases anxiety stress irritability or excitement by increasing a sense of will be essential component in sleeping pills. Nora adrenaline responsible for mood changes when Nora adrenaline is in low levels signal sending activities low that causes depression then doctors prescribe anti depressing drugs.

Question 20

Types of tranquilizers and examples

Answer 20

Strong tranquilizers that is Iproniazid and Phenelzine(nardil)
Mild tranquilizers that are Choloridiazepoxide ,Meprobamate, Equanil
Barbiturates- hypnotic drugs produce sleep
