Non-narcotic drugs Flashcards
(54 cards)
What are non narcotic anlgesics
CNS depressent with no narcosis
Dec. temp
Most
what is mechanism of non narcotic anlgesics
decrease COX
decrease synthesis of 3
Talk about COX-1
PSYCHIC
STOMACH
KIDNEY
TALK ABOUT COX-2
inflamation : pathological
increase PG–> inflamation
example of toxins of infections
IL-1
TNF
example for NSAID which is non selective COX inhibitors
Asprin ( salisclate)
example for NSAID which is slective COX inhibtors
Celecoxib
rofecoxib
Why dont we use saliscylic acid
very irritant
talk about saliscylic acid dervivtives for systemic & local use
S : A-N-SM-Diflunisal
L : SA-MS
Talk about pharmokinetcs of saliscylate
Absorption : Orall-stomach-intestine
Distribution : All-Tissues-albumin
Hepatic metabolism : mostly-little
Excretion : Mainly-Alklinzation
Talk about pharmokinetcs of paracetamol
Absorption : well
Hepatic metabolism : 95&-5%-large dose
Excretion : mostly metabolite-5% uncharged
Duration: 2-3
NABQ accumlation lead to
nephrotoxicity & hepatotoxicity
duration of paracetamol
2-3
what are the elements that conjugate paracetoml & saliscylate
S : G-G
P : G-S-GT
Talk about dynamics of salicylate of C.N.S
CNS :-
A: Central - peripheral : decrease PG: sensitivity
Anti-pyretic : dec. PG : heat loss-toxic dose :anti-gaba
Talk about dynamics of salicylate of blood
Inflamation : decrease leucosytosis to normal
Hypothermia: large dose for long use
irreversible dec. platlet aggregation : small dose
heamolysis in favism
Talk about dynamics of salicylate of uterus
dec.PG : relax uterus: tocolytic
Talk about dynamics of salicylate of uric acid
large dose : hyperuricema
small dose : urisucoric
Talk about dynamics of salicylate of endocrine
increase hypothalamus
Increase adrenal medula
Increase displace of T3 & T4 : dec. T.S.H
Talk about dynamics of salicylate of imune response
Increase cortisol : decrease Ag/At
Talk about dynamics of salicylate of metabolism
Carb.:-
moderate dose: insulin like
large dose: hyperglycemia
Fat: lipolysis ketosis
Protein : catabolic : negative protein balance
B.M.R :increase
Talk about dynamics of salicylate of liver
hydrocholric
increase adrenaline
hepatotoxic
Talk about dynamics of salicylate of kidney
decrease P.G & RENAL V.D : VC–> decrease R.M.F
large dose : neuropathy
Talk about dynamics of salicylate of G.I.T
Local : irritation
systmeic: Hyperacidity
