This prophylactic drug inhibits histamine from being released by working on the mast cell
|
Cromolyn (only Mast Cell Stabilizer)
|
|
If someone has an allergic reaction, Cromylin (a Mast Cell stabilizer) won't work right away. T or F
|
True. Once histamine is released, it sits on H1 receptor. Once it comes off, it's metabolized by the body in approx. 3 days.
|
|
Drugs can be used prophylactically for seasonal allergies.
|
True
|
|
Antihistamines work by blocking the______ receptor. May get partial relief w/ antihistamines due to:_______
|
1. H1 receptor
(3 days to work because receptor is already occupied) Anticholinergic affect (ACh receptor gets blocked) |
|
Won't get full antihistamine, anti-allergy affect, but some anticholinergic relief esp. with nasal allergies.
|
True
|
|
When the H1 receptors are blocked by antihistamines, the following BLOCKAGES occurs:
1. vasodilation of capillaries 2. itch on nerve endings 3. bronchoconstriction of bronchial smooth muscles. |
(opposite when H1 STIMULATES the receptors)
|
|
What are the side effects of antihistamines?
|
1. all have sedating properties
Diphenhydramine (Benadryl) is the most sedating. 2. Anticholinergic |
|
T or F, therapeutic use of antihistamines include:
1. Exudative Allergies (drainage, runny nose) 2. Allergic Dermititis (hives, urticaria/eyes) 3. Pruritis, or itching |
True
|
|
Diphenhydramine (Benadryl) & Cetirizine (Zyrtec) are highly sedating antihistamines.
|
True
|
|
(Dimetane) & (Chlor-Trimeton) are less sedating antihistamines than Benadryl & Zyrtec
|
True
|
|
LONG acting antihistamines with a lower incidence of drowsiness:
(Allegra) & (Claritin) |
True
|
|
Aminophylline & Theophylline (Theodur) are
|
Theophyllines (The/oph/llines)
(treat asthma) |
|
The following effects describe:
1. Diuretic effect 2. Bronchodilation 3. Tachychardic at high doses 4. Seizures at high doses WHICH? A. Leukotriene Antagonists B. Theophyllins C. Adrenergic Bronchodialators |
Theopyllines
|
|
Monitor patient when on Theophyllines--Two early signs of toxicity:
|
1. Seizures
2. Increased heart rate (tachycardic) |
|
Category of asthma drugs that can induce seizures or Tachycardia at high doses
|
Theophylines
Aminophylline & Theophylline |
|
Zafirlukast & Montelukast are what kinds of drugs?
|
LEUKOtriene Receptor Antagonists
(relaxes bronchial smooth muscle) ZafirLUKAST & MonteLEUKAST |
|
Adrenergic drugs like:
Albuterol & Epinephrine stimulates BETA 2 receptors |
(shouldn't overuse inhalers or could get chest pain)
|
|
What is the best way to avoid spillover to Beta 1 (the heart)?
Bronchodialator with the least probability of Beta 1 spillover: |
Inhaler (for Beta 2 property of bronchodilation)
Albuterol |
|
Best route of administration for corticosteroids so it doesn't go systemic?
|
Inhaler.
Wash out mouth (prone to thrush fungal infection) |
|
When given corticosteroids NASALLY, what are you treating?
|
Allergic rhinitis (allergies, inflammation, runny nose)
|
|
"Mast Cell Stabilizer"
1. Co-trimoxisole 2. Acetylcysteine 3. Cromolyn 4. Aminophylline |
Cromolyn
|
|
Potassium Iodide (SSKI) is a
1. Antihistamines 2. Expectorant 3. Adrenergic Bronchodilator |
Expectorants
(controversial effectiveness) would have to drink 4 oz bottle every day & drink H20 |
|
Robutussin & SSKI are _______that stimulate "production & viscosity" of mucous:
1. Antihistamines 2. Mucolytics 3. Expectorants |
Expectorants

Administered via respiratory therapy (nebulizer) |
|
Parietal cells in the stomach release acid & intrinsic factors when _______is activated by the H2 receptor.
|

|
|
This drug inhibits histamine prophylactically by working on the mast cell:
1. Cyproheptadine (Periactin) 2. Cromolyn 3. Albuterol |
Cromolyn
|
|
Acetylcysteine (Mucomyst) protects kidneys from toxic dyes.
|
True
(Also, a mucolytic agent) |

(allergies, inflammation, runny nose) |
|
Less chance of Beta 1 spillover with this Bronchodilator:
1. Metaproterenol 2. Albuterol 3. Terbutaline |
Albuterol
