Tablet

Question 13

is a dose form in which a powdered or liquid drug is contained in a gelatin shell. The gelatin shell dissolves in the stomach and releases its contents.

Answer 13

Capsule

Question 14

Answer 17

Suspension

Question 18

It is a dose form that permits a drug to be applied on the skin surface, where it is absorbed into the bloodstream. The patch-like device containing the drug is applied to the skin with a water-resistant covering.

Answer 18

Transdermal patch

Question 19

Derived from the drug opium or synthetic versions that mimic the chemical structure of opium. It interacts with neurotransmitters in the brain to block signals. They cause both intense feelings of pleasure and can block pain.

Answer 19

Opioids

Question 20

It is a central nervous system (CNS) depressant. It causes severe long-term damage to the liver.

Answer 20

Alcohol

Question 21

These drugs function by interacting with a neurotransmitter called GABA (gamma-aminobutyric a c i d . These drugs impact the body and mind differently but generally create calming and sedative effects.

Answer 21

Benzodiazepines and barbiturates

Question 22

These drugs accelerate the activity of CNS, making a person feel energized, focused, and alert for a long period of time. The converse reaction is that a person feels paranoid and angry.

Answer 22

Cocaine and other stimulants:

Question 23

Mostly consumed through breathing, these drugs can exist in vapour form at room temperature. They tend to be less addictive than other substances but are dangerous.

Answer 23

Inhalants

: Affects the cannabinoid receptors in the brain and comes in different forms.

Answer 25

Cannabis

Question 26

This refers to anything that has been created (in a laboratory) to mimic naturally occurring drugs.

Answer 26

New psychoactive substances

Question 27

When the drug does not produce any chemical reaction or change in the cells of the body and the effect is only physical.

Answer 27

Physical mechanism

Question 28

Drugs act by producing chemical reaction in the body.

Answer 28

Chemical mechanism

Question 29

Macromolecules protein in nature which are target sites for drugs. Most drugs have to bind receptors to produce effects. Receptors are located mostly on the cell membrane but certain intracellular receptors are found
as well.

Answer 29

Drug-receptor interaction

Question 30

These are the drugs which when bind to receptors, causes activation of receptors. They have the capacity to produce chain reactions in the
receptors which ultimately bring about the effects.

Answer 30

Agonist

Question 31

: Binding of drug with the receptor is the same. Most of the drugs
binding receptors resemble the agonist but they cannot activate the
receptors, and also prevents agonist binding. Thus opposite effect occurs in case of agonist and antagonist.

Answer 31

Antagonist

Question 32

It is similar to drug receptor interactions. These drugs resemble the natural substrates, bind enzymes and cause change in their activity. This may take place by: activation of enzymes and inhibition of enzymes.

Answer 32

Drug-enzyme interactions:

Question 33

: The drug interferes with the flow of ions through the channels specific for these ions.

Answer 33

Drug-channel interactions

Question 34

The drug effect occurs in immediate vicinity/area of which the drug is
applied or introduced.

Answer 34

Local effect

Question 35

The effect takes place away from the site of administration.

Answer 35

Question 36

: It is the desired effect or the treatment of disease for which the drug
is given.

Answer 36

When they are undesirable, these are called adverse or side effects.

Answer 37

. Side effect
