CHEMISTRY IN EVERYDAY LIFE

NEUROLOGICALLY ACTIVE DRUGS


(A) Tranquilizers
(B) Analgesics
1.) Non – narcotic
2.) Narcotic
Drugs which affect the message transfer mechanism from nerve to receptor are known as
neurologically active drugs .

(1) Tranquilizers:
 These are the drugs which are used for the treatment of
• stress
• Anxiety
• Irritability
• mild or even severe mental diseases.
• used in making sleeping pills.

 noradrenaline : It is one of the neurotransmitters that plays an important role in


mood changes. If the level of noradrenaline is low for some reason,
then the signal-sending activity becomes low, and the person suffers
from depression.
 In such cases anti-depressant drugs are required which increases the level of noradrenaline .
Some examples of such anti-depressant drugs : Iproniazid and phenelzine

 chlordiazepoxide and meprobamate, are relatively mild tranquilizers suitable for relieving
tension.

 Equanil is used in controlling depression and hypertension.


 Barbiturates are hypnotic, i.e., sleep producing agents.
Examples : veronal, amytal, nembutal, luminal and seconal
 Some other substances used as tranquilizers are valium and serotonin.
(2.) Analgesics:
Analgesics reduce or abolish pain without causing impairment of consciousness, mental
confusion, incoordination or paralysis or some other disturbances of nervous system.
(A) Non-narcotic (non-addictive) analgesics: Aspirin and paracetamol belong to the class
of non-narcotic analgesics.
 prostaglandins which stimulate inflammation in the tissue that cause pain.
 relieves skeletal pain due to arthritis.
 reducing fever (antipyretic) and preventing platelet coagulation.
 Because of its anti blood clotting action, it prevents heart attacks.
 Other examples of such analgesics : Crocin , Combiflam etc .

crocin
Aspirina
(B) Narcotic analgesics: Morphine and many of its homologues, when administered in
medicinal doses, relieve pain and produce sleep.
 In poisonous doses, these produce stupor, coma, convulsions and ultimately death.
 Morphine narcotics are sometimes referred to as opiates, since they are obtained from
the opium poppy.
 These analgesics are chiefly used for the relief of postoperative pain, cardiac pain and
pains of terminal cancer, and in child birth.

 Some other examples of narcotic analgesics ; Microdosed LSD , oxycontin, endone etc.
