Q

What is the danger of owners using over the counter decongestants for their pets?

A

If the pet has any underlying cardiac issues, these drugs can be dangerous due to Beta1 sympathetic receptor stimulation.

Q

How do anticholinergic bronchodilators work?

A

They bind to ach receptors to prevent bronchoconstriction.

- they block the PSNS nerve reflexes that cause the airways to constrict= they remain open

Stimulate the B2 receptors

-relaxes bronchiole smooth muscle causing them to dilate

What are the side effects of Yohimbine?

A

CNS stimulation

Muscle tremors

24
Q

What are the two ways to suppress a non-productive cough?

A

Centrally acting

Local

25
Q

In cases of tracheitis or tracheobronchitis, which class of drugs may be used?

A

Antitussives

26
Q

What are the two types ( subheadings) of Antitussives available?

A

Controlled

Non-controlled

27
Q

What side effects does atropine have?

A 
Dry mouth
Dry Eyes
Tachycardia
Vomiting
Constipation
Urinary retention
28
Q

What are the two classes of bronchodilators?

A

Anticholinergics

B2 Adrenergic agonists

29
Q

What are some alternate methods we can suggest for treatment of pets with congestion?

A

Cool air vaporizers
Warm compresses
Saline solution drops

30
Q

Besides being an expectorant, what is guafenesin used for?

A

Muscle relaxant in horses

31
Q

Which drug is used for emergency treatment for feline asthma?

A

Terbutaline

32
Q

Which class of respiratory drugs work by inhibiting an enzyme that promotes bronchoconstriction?

A

Methylxanthines

33
Q

How do antihistamines work?

A

Histamines are released from mast cells- they bind to receptors on smooth muscle causing bronchoconstriction = Antihistamines block the smooth muscle receptors

34

A

Naloxone

35
Q

Which Antitussive drugs are controlled?

A

Morphine
Codeine
Hydrocodone
Butorphanol

36
Q

Which of the controlled Antitussives is the most powerful?

A

Hydrocodone

37
Q

Which of the controlled Antitussive drugs has the least cardiovascular and respiratory depressive affects?

A

Butorphanol

38
Q

Which Antitussive drug is a combination of antihistamine and prednisolone?

A

Trimeprazine ( Vanectyl-P)

39
Q

What are the side effects of trimeprazine?

A 
PU/PD
Polyphagia
Sedation
Depression
Hypotension
40
Q

Which Antitussive drug is not often used in veterinary medicine but is significant as owners may give it at home?

A

Dextramethoprhan

41
Q

Which of the Antitussives are opioids?

A

Codeine
Morphine
Hydrocodone
Butorphanol

42
Q

Which reversal drug can be used for the opioid class of Antitussives?

A

Naloxone

43
Q

What are the common opioid side effects?

A

Sedation and constipation

44
Q

Which class of drugs will be used to remove mucus that cannot easily be removed by cilia?

A

Mucolytics and expectorants

45
Q

How do mucolytics work?

A

Break down the mucus by breaking disulphide bonds….allows mucus to be moved out of resp tract easier

46
Q

Which drug is a mucolytic?

A

Acetylcysteine

47
Q

How can acetylcysteine be administered?

A

PO
IV
Nebulizer

48
Q

Besides being a mucolytic, what else can acetylcysteine be used for in cats?

A

Used to treat acetaminophen toxicity in cats

49
Q

Which medication could be used on a productive cough?

A

Guafenesin - makes the mucus easier to cough out

50
Q

What kind of drug is guafenesin?

A

Expectorant

51
Q

Which medication is used to keep dry, irritated tissues moist?

A

Guafenesin

52
Q

Does the use of an expectorant increase or decrease muco content?

A

Increases - waters it down so easier to bring up

53
Q

Which drugs are used to treat feline asthma?

A 
Diphenhydramine/Chlorphenarimine
Aminophyline
