Chemistry In Everyday Life Flashcards
analgesics have pain killing effect/kill the growth of microorganisms
analgseics have pain killing effect
what are antagonists
drugs that bind to the receptor site and inhibit its natural function are called antagonists
antiseptics have pain killing effect/ kill the microorganisms
kill the microorganisms
what are agonists
drugs that mimic the natural messenger by switching on the receptor, these are called agonists
(mimicking is an agony)
what happens if hydrogen carbonate is taken in excessive amounts to battle acidity
the stomach becomes alkaline and trigger the production of even more acid
why are metal hydroxides a better alternative than hydrogen carbonates
metal carbonates being insoluble do not increase the pH above neutrality
whats the function of histamine
histamine stimulates the secretion of pepsin and HCl in the stomach
what drug was invented to prevent action with histamine and became largest selling drug
cimetidine(tegamet)
what was cimetidine replaced with?
ranitidine(zantac)
whats histamine’s function in nasal area
histamine contracts the smooth muscles in the bronchi and gut and relaxes other muscles such as those in the walls of fine blood vessels
and also associated with common cold and allergic response to pollen
eg of anithistamines
brompheniramine(dimetapp) and terfenadine(seldane)
structure of histamine
structure of bromopheniramine
structure of terfenadine
why does the antihistamines no affect the secretion of acid in the stomach
because the antiallergic and antiacid drus work on different receptors
what is noradrenaline
noradrenaline is one of the neurotransmitters that plays a role in mood changes
what happens if the level of nordranaline is low and what kind of drus is required here
the signal sending activity becomes low and the person suffers from depression
antidepressant drugs are required
eg of anidepressants
iproniazid and phenelzine
mild tranquilizer eg for relieving tension
meprobamate and chlordiazepoxide
drugs used ins controlling depression and hypertension
equanil
what do barbituaries do?
barbituaries are hypnotic , induces sleep
eg of non narcotic analgesics
paracetamol and aspirin
what other effects does paracetamol and aspirin has? and what does that effect doing drugs are called
reducing fever and reduces platelets
antipyretic(reducing fever)
what is used in preventino of heart attacks and why?
aspirin is used because of its blood clotting actions
eg of addictive analgesics
morphine,codeine,heroin
from where are morpines obtained
opium
where are usually addictive analgesics used?
cardiac pain,terminal cancer and in child birth
what was developed for the treatment of syphilis
arsphenamine also known as salvarsan
whats the first effective antibacterial agent
prontosil which is a little similar to salvarsan in structure
to what is prontosil converted to in the body
sulphanilamide which is the real active compound
bactericidal antibiotics eg
penicillin
aminoglycosides
ofloxacin
PAO
bacteriostatic antibiotic eg
erythromycin
tetracycline
cholramphenicol
ETC
what is used to fight typhoid, dysntery,acute fever and some urinary enfections
chloramphenicol
antibiotic toxic towards cancer cells
dysiderazirine
eg of antiseptics
furacine, soframacine,dettol
dettol is made of
choloxylenol and terpineol
what is added to spads to inpart antiseptic
bithional
whats tincture of iodine
2-3% iodine in alchool water micture
iodoform is a antiseptic for wounds! true/false
true
weak antiseptic for eyes is
boric acid in dilute aqueous solutions
disinfectant eg
phenol(0.2%)
cholrine(0.2-0.4 ppm)
sulphur dioxide in very low concetration
what does birth control pills essecitally contains
musciture of syntheti estrogen and prosesterone detivaties
what does progesterone do?
suppressse ovulation
eg of synthtic progesterone
norethindrone
estrogen derivative used with progesterone
novestrol(ethynylestradiol)
structure of morphine
structure of heroin
structure of codiene
structure of salvarsan
structure of penicillin
structure of chloramphenicol
structure of novestrol
