Eye Drugs Flashcards
(47 cards)
antiallergic ophthalmic drugs
- works by BLOCKING HISTAMINE RECEPTORS to block histamine release from mast cells
- decreases EYE IRRITATION & ITCHING
antiallergic ophthalmic - indications
- allergic conjunctivitis
- keratitis
antiallergic ophthalmic - adverse effects
- BURNING & TEARING of eye
- pancytopenia (deficiency in blood cells) *CROMOLYN
- corneal ulcers/ocular edema *LODOXAMIDE
anesthetics
- works by anesthetizing the cornea
- important for application of measurement of IOP, removing any foreign bodies, or scraping of conjunctiva or cornea
- prevents IRRITATION and TRANSMISSION of NERVE IMPULSES
Anesthetics - what are they?
- proparacaine
- tetracaine
(end in caine)
anesthetics - adv effects
- eye pain
- redness
- contact dermatitis
- (rare) seizures or CNS depression
anti-infectives - MOA
- can be either BACTERIOSTATIC/CIDAL *bacteria
- binds to cell membrane STEROLS and increases permeability *antifungal
- or inhibits DNA synthesis *antiviral
anti-infectives - indications
- corneal ulcers
- conjunctivitis *bacterial, fungal or viral
anti-infectives - adv effects
- itching
- burning
- ocular irritation
- conjunctivitis
- *SJ SYNDROME *with SULFACETAMIDE and TOBRAMYCIN
examples of anti-infectives for fun :0
Azithromycin, bacitracin, ciprofloxacin, erythromycin, gentamycin, levofloxacin,
natamycin, ofloxacin, sulfacetamide, tobramycin, trifluridine, & trimethoprim-
polymyxin B
(many end in -cin)
anti-inflammatories *STEROIDAL
- decreases the IMMUNE RESPONSE at the site of inflammation
- always want to assess if patient is on multiple steroids > can increase risk of CUSHINGS DZ
what are our steroidal anti-inflammatories?
- dexamethasone
- fluorometholone
- loteprednol
- prednisolone
adv effects - steroidal anti-inflammatories
- stinging and burning
- secondary ocular infections
- delayed corneal healing *with longer use
non-steroidal anti-inflammatories
- for DECREASING INFLAMMATION and ITCHING
- helps to treat OCULAR INFLAM after surgery
- do NOT COMBINE with ENOXAPARIN > leads to increased risk of OCULAR BLEEDING
what are our non-steroidal anti-inflammatories?
- diclofenac
- ketorolac
*end in lac
adverse effects - non-steroidal anti-inflammatories
- ocular irritation
- keratitis
- blurred vision
lubricants
- acts as ARTIFICAL TEARS to lubricate cornea
- can act as a PROTECTANT during procedures
- helps to MOISTEN contact lens
- mainly OTC
adverse effects - lubricants
- ocular irritation
- photophobia
- transient blurred vision
what are our eye lubricants?
- carboxymethylcellulose (refresh)
- hydroxypropyl cellulose
- polyvinyl alcohol
what is the difference between MYDRIATICS & CYCLOPLEGICS?
- MYDRIATICS: DILATES the eye
- CYCLOPLEGICS: temporarily paralyzes the EYE MUSCLE
mainly used for eye exams, procedures, or treating iris conditions
what are our MYRDRIATICS and CYCLOPLEGICS?
- atropine sulfate (AS)
- cyclopentolate (CY)
- phenylephrine (PH)
- tropicamide (TRO)
drug interactions - mydriatics & cycloplegics
- AS, CY, & TRO; should not be combined with CLOZAPINE *increases risk of ANTICHOLINERGIC TOXICITY
- AS & PH; decreases VALSARTAN & AMLODIPINE
- AS & PH; increases HTN w/ IBUPROFEN, CAFFEINE, & MODAFINIL
- CY & TRO; w/ CLOMIPRAMINE = increases ANTICHOL ADV EFFECTS
- PH; not good with COCAINE USERS/MAOIs *causes arrhythmias
adverse effects - mydriatrics & cycloplegics
- blurry vision
- conjunctivitis
- IOP
- photophobia
severe ones;
- seizures, tachy, resp. depression w/ AS, CY, & TRO
- PH; tachy, subara. hemorrhages, or MI
beta-adrenergic blockers
- prevents & controls ELEVATED IOP for acute ANGLE-CLOSURE & OPEN-ANGLE GLAUCOMA
- decreases the AQUEOUS HUMOR; blocks nerve endings to produce fluid
