Pharmacology &
toxicology
Important give reasons
yo.gesh954
1] why Acetylcholine is not used in clinically
1] It is rapidly metabolized in GIT enzymes
2] on parentrals administration itis the destroyed in the plasma by enzyme
PSEDOCHOLINE EASTERAGE At the site of action by enzyme True
choline easterage
3] Being The quaternay ammonium compounds it does not cross Blood
Brain Barrier
4] HEANCE it inffeactive for CNS action
yo.gesh954
2] Multidrug Therapy is effective in the treatment
of TB
1] The singal dose is develop the resistance to TB
2] Combination drug are better resistance bacteria
3] combination drug is produced SYNERJUSTIC
effects
4] combination drug reduces side effects
5] It is various advantages so it is used in combination
therapy
yo.gesh954
3] Antibiotics are given in
combination
1]Generally, antibiotics are given in combination to

2]It produces SYNERJUSTIC effects
3]It is used for various mixed infection like
Pneumonia
4]To avoid the delopment of resistance
yo.gesh954
4]Sulphonamides are not used in now a days
1]Sulphonamides are various side effects
2]Sulpha drugs are produced Fever, skin rash, joint pain, anemia,
etc

6]Carbidopa is can't cross BBB,BUT it inhibits decarboxylase
enzymes yo.gesh954
7] Insulin is not given in orally?

increasing Intestinal muscles tone also increase
peristalsis
3] The tincture of opium is Reduce intestinal muscle tone
or reduce peristalsis
4]Heance , tincture of opium is used
yo.gesh954
9] Atropine produce photophobia?
1]Atropine is a antimuscarnic drug which wide range of used in
eye, which inhibits Mascarnic receptar this causes mydrasis
2] The capillary smooth muscle is paralyzed & person increase
the focal length.
3] The individual the percon see the object only long distance ,
This term is called cyclopegia or spam of accommodation

11] Cheese or butter is contraindication during MOA
inhibitor therapy
1i Banana,chocklets ,cheese ,Bitter contain
THYRAMINE
2] THYRAMINE is not metabolized in liver by enzyme
MONOAMONO OIIDASE
3]MAO is metabolized by THRYAMINE
4] Thrymaine is not metabolized & they are
Accumulated in the body
5] It produces sympathomimetics stimulation to increase
yo.gesh954
1] It is used to compare to therapeutically index of toxic Dose
2] It is a statement relatively to safety
3] It is the ratio of dose
4] It produces desired therapeutic respond to toxic response
5] The common TI to toxic response 50% Dose response
It incluid TD50 & ED 50
6] It safety of margin uselly calculated toxic Dose ratio to 1%
population. TD=01% ED=99%
TD= THERAPEUTICDOSE, ED= EFFECTIVE DOSE
12] Higher therapeutic index safer will be drug justifies the
statement
yo.gesh954
13] Asprine is not given in peptic ulcer?
1] Asprine is not given in peptic ulcer because it
administered after food
2] postaglandin control Acid secreation
3] Asprine inhibits postaglandin &COX enzyme
Synthesis
4] To avoid the side effects Of asprine it
administered in after food
5] It gives increases, ulceration. yo.gesh954
]
14]Penicillin is life saving drug as well as treating drug

4] combined drugs are produced SYNERJUSTIC effects
5]It reduced side effects & produces advantage
yo.gesh954
16] StrEptomycine is Not Given in
orally
1] Strwptomycine absorption rate is slow
2] pharmacological action is slow of Strwptomycine
3] It does not used in emergency
4] Can not used in uncooperative patient
5] Irritation offer GIT track
6] Nausea ,vomiting are produce
7] It destroyed on gastrointestinal track
yo.gesh954
17] Digatilis is called Cardiotonic
1] Increased force of contraction
2] Digatilis is increases cardiac output
3] Digatilis is increases contratility not a
rate of heart beat
4] working capacity Of heart is increased
5] Digatilis is also called as a cardiac
glycoside

2] Neostigamine is a reverseable anticholinestrage
3] Neostigamine is parasympathomimytic drugs
4] It's action with both Mascarnic or nicotinic receptors
5] Mystheniya gravis is a only Nicotinic receptor action only
6] It suppress Mascarnic effect hence Atropine gives along
with Neostigamine
19] ADRANALIN is always present in emergency k

yo.gesh954
23] why BZD (BENZODIAZIPINE) are popular than Barbichurate?
1] BZN is higher therapeutic Index, Ever 20 hypnotics doses do not
Dangerous
2] Do not affect in cardiavascular & respiratory systems
3] No affect on other body functions or systems
4] Drug depends is less marked
5] Do not induces microsomal enzymes
6] Specific antitode like FLUMAZENIL (0.2MG IV) is avalible
Heanc bzdis are more popular than Barbichurates
yo.gesh954
24] Combination of Atropine & eighter is given in
GENERAL ANAESTHETIC?
1]Eather is a drug of general anaesthetic
2] The eather is produced irritation vapours to respiratory tract
3] This irritation causes secretion of normal respiration as well
as with Anesthetic process
4] To avoid this effect Atropine is given or used
5] Atropine is Antisecratory drug which leads to reduce
secreations
6] Atropine block secretion & assist in the anaesthesia
yo.gesh954
25] Morphine is contraindication in Brain injury
1] morphine is increases Interacramial pressure &
wornes Bleeding condition in head injuries
2] It depresses respiration, produce Moises & mental
clouding or causes complications in head injuries
HEANCE morphine is contraindication in head injury
26] Barbichurates are Develops tolerance &
automation1] Barbichurates induce microzomal enzyme
system In liver while in activates Barbichurate
2] The inactivation increase in repated
admination, this develops tolerance
3] In repated admination of barbiturate also
causes mental confusioN & Forgetfulne
because of which person is unable to fall sleep
To takes pills making poisons him produce drug
automatism,
4] HEANCE Barbichurates developes tolerance
& automatism
1] Morphine is opioid AGONIST it action on smooth muscle of GIT
& action is comtraction, decrease tone of intestinal & reduced
peristalsis
2] Morphine is also refuse sensitivety offer intestinal muscle to
deflection reflexes
3] This causes The stagnation if food material, resulting in
maximum absorption of water, makes stool dred & heard to
frequency & output of
Deflection is reduced
4] The above action of morphine is resulting into constipation
27] Morphine causes
constipation ?
27] Morphine causes Addition?
1] Morphine is indicated for many disorder like Pani, cough,
diarrhea ,
Myocardial infarction, etc
2] Morphine improve above condition also In turn cause
Euphoria.
I. E= state Of mind well being
3] To positive state of mind Individual continuous the drug on
its own
With out therapeutic indication
4] This develops tolerance & storage degree of physiological
drug dependence which in true cause addition
