Midterm 1 Drugs to Know Flashcards
cocaine
topical anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”; local cellular enzymes break down the anesthetic over time;
*indirect acting adrenergic; blocks re-uptake of norepinephrine; potentiates adrenergic (sympathetic) activity; results in mydriasis and vasoconstriction\
mydriatic
indirect acting adrenergic agonist; inhibits reuptake of NE; causes mydriasis and vasoconstriction; only about 2 mm of mydriasis
tetracaine
topical anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”; local cellular enzymes break down the anesthetic over time
benoxinate
topical anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”; local cellular enzymes break down the anesthetic over time
proparacaine
topical anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”; local cellular enzymes break down the anesthetic over time
lidocaine
topical anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”
procaine hydrochloride (novacain)
injection anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”
lidocaine hydrochloride (xylocain)
injection anesthetic
drug crosses membrane - non-ionized and lipid-soluble;

mepivacaine hydrochloride (carbocaine)
injection anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”
bupivacaine hydrochloride (marcaine)
injection anesthetic
drug crosses membrane - non-ionized and lipid-soluble;
drug becomes ionized inside cell and temporarily blocks Na channel; depolarization cannot occur with blocked Na channel; pain signal cannot be sent “downstream”
epinephrine
vasoconstrictor added in combination with injection anesthetics; prolongs duration, decreases systemic absorption, decreases bleeding
pilocarpine
miotic
muscarinic cholinergic agonist; iris sphincter contraction- pupil constriction; ciliary muscle contraction- accommodation and increased aqueous flow
scopolamine
cycloplegic
cholinergic antagonist- blocks ACh receptors, decreasing parasympathetic activity, increases sympathetic activity;
causes pupil dilation and paresis of accommodation
tropicamide
cycloplegic
cholinergic antagonist- blocks ACh receptors, decreasing parasympathetic activity, increases sympathetic activity;
causes pupil dilation and paresis of accommodation
atropine
cycloplegic
cholinergic antagonist- blocks ACh receptors, decreasing parasympathetic activity, increases sympathetic activity;
causes pupil dilation and paresis of accommodation
cyclopentolate
cycloplegic
cholinergic antagonist- blocks ACh receptors, decreasing parasympathetic activity, increases sympathetic activity;
causes pupil dilation and paresis of accommodation
homatropine
cycloplegic
cholinergic antagonist- blocks ACh receptors, decreasing parasympathetic activity, increases sympathetic activity;
causes pupil dilation and paresis of accommodation
phenylephrine
mydriatic
direct-acting alpha 1 agonist; mimics effects of NE; stimulates iris dilator muscle; produces conjunctival vasoconstriction
hydroxyamphetamine
mydriatic
indirect acting adrenergic agonist; inhibits reuptake of NE with some stimulation of NE release
dapiprazole (Rev-Eyes)
mydriolytic
adrenergic antagonist; blocks adrenergic receptors; causes miosis; “reversal of dilation”

Pred Mild
prednisolone acetate 0.1%
topical corticosteroid
inhibits phospholipase A2 which decreases synthesis of prostaglandins and leukotrienes; decreases synthesis of cyclooxygenase-2 which decreases synthesis of prostaglandins
Inflamase Forte
prednisolone sodium phosphate 1%
topical corticosteroid
inhibits phospholipase A2 which decreases synthesis of prostaglandins and leukotrienes; decreases synthesis of cyclooxygenase-2 which decreases synthesis of prostaglandins
