Definition
antimuscarinics
(and 1st generation antihistamines)
Term
azelastine nasal spray
Definition
antihistamine
Term
actions of azelastine nasal spray
Definition
reduces itching and sneezing
has some actions on rhinorrhea and nasal congestion
Term

Definition
vasoconstriction
reduces edema
Term
phenylephrine
Definition
nasal decongestant
alpha-adrenergic agonist
Term
Alpha-adrenergic agonists are only effective for what?
Definition
nasal decongestion

(not sneezing, itching, rhinorrhea)
Term
Why should nasal decongestants not be used more than 3 days?
Definition
to avoid rebound congestion and rhinitis medicamentosa
Term
Can oral decongestants be used prolonged without significant rebound congestion?
Definition
yes, but must be careful with hypertension
Term
ipratropium bromide
Definition
antimuscarinic
only works on rhinorrhea

(also used in COPD)
Term

Definition
rhinitis
chronic postnasal drip syndrome
bronchodilation (esp. COPD)
Term
Ipratropium bromide is an _________ analog.
Definition
atropine (antimuscarinic)
Term
cromolyn compound mechanism of action
Definition
indirectly inhibits antigen-induced rhinitis

directly inhibit the release of histamine and other autocoids from sensitized mast cells

may suppress the activating effects of chemoattractant peptides on eosinophils, neutrophils, and monocytes
Term
What are the most effective drugs available for relief of symptoms of allergic rhinitis?
Definition
intranasal corticosteroids
Term
actions of intranasal corticosteroids
Definition
reduce sneezing, itching, discharge, and congestion
Term
Why do you not use intranasal corticosteroids for acute symptoms?
Definition
can take over a week to have effect
Term

Definition
middle ear congestion
Term
Intranasal corticosteroids can/cannot be used as first-line drug.
Definition
can
Term
side effects of intranasal corticosteroids
Definition
usually mild

dryness, irritation, burning of nasal mucosa
sore throat
nose bleed (epistaxis)
headache
URI
Term
most common form of ocular allergy
Definition
allergic conjunctivitis
Term
treatment of allergic conjunctivitis
Definition
oral or topical antihistamine
antihistamine/decongestant combo
Term
advantages of topical antihistamines for allergic conjunctivitis
Definition
may be more rapid acting than oral
also anti-inflammatory
Term
pheniramine/naphazoline
Definition
Visine A
antihistamine/decongestant combo eye drops
Term
pheniramine/naphazoline are __________ acting and can cause _____________ with continued use
Definition

Term
azelastine ocular (Optivar)
Definition
topical ocular H1 antihistamine
Term
side effects of azelastine ocular (Optivar)
Definition
eye burning
conjucntivitis
rarely dyspnea and asthma
Term
intense increased IOP due to an anterior chanmber occlusion with dilation of pupil
Definition
acute, angle closure glaucoma
Term
increased IOP without occlusion of anterior chamber; asymptomatic
Definition
open angle glaucoma
Term
goal of treatment for open angle glaucoma
Definition
decrease secretion of aqueous humor
increase outflow from the globe
Term
What drugs can be used to increase the outflow of aqueous humor?
Definition
alpha agonists
muscarinic agonists
cholinesterase inhibitors
PGF2alpha analogs
Term
What drugs can be used to decrease production of aqueous humor?
Definition
beta blockers
carbonic anhydrase inhibitors
alpha agonists???
Term
What does stimulation of beta adrenergic receptors do in the eye?
Definition
stimulates secretion of aqueous humor
Term
betaxolol
Definition
beta-1 selective blocker used for glaucoma
Term
timolol
Definition
non-selective beta-1/2 blocker used for glaucoma
Term
side effects of beta blockers used for treatment of glaucoma
Definition
typically local

discomfort, blurred vision, conjunctivitis, periorbital edema

if sufficient systemic absorption occurs, non-selective agents can exacerbate asthma and either class can slow the heart
Term
dipivefrin
Definition
non-selective alpha-1/2 agonist used for glaucoma

increases aqueous humor outflow
Term

Definition
prostamide
Term
side effects of bimatoprost
Definition
increase in brown pigment in eyes, eyelashes, eyelids

eye irritation and discharge, sensitivity to light, changes in vision

rare allergic response: hives and anaphylaxis
Term

Definition
carbonic anhydrase inhibitor
Term
