1
Q

Doxazosin trade name

A

Cardura

2
Q

Doxazosin expected effect

A
  • vasodilate peripheral blood vessels

- block alpha (adrenergic) receptors to reduce blood pressure

3
Q

Why use doxazosin

A
  • hypertension
  • benign prostatic hyperplasia
  • urinary outflow obstruction
4
Q

Doxazosin adverse effects

A
  • dysrhythmias

- hepatitis

5
Q

Doxazosin dosages

A
  • 1-8mg/ day for BPH

- 4-16mg/ day for hypertension

6
Q

Doxazosin drug classification

A

alpha adrenergic blocker

7
Q

Doxazosin routes of admin

A

PO

8
Q

Doxazosin nursing implications

A

Hypertension

  • check BP after each dose
  • assess crackles, dyspnea, orthopnea
  • check pulse
  • look for distension of jugular vein

BPH

  • assess urinary patterns (hesitancy, dribbling, urgency, nocturne, incontinence etc)
  • assess weight changes & edema
9
Q

Prazosin drug classification

A

Alpha Blocker (chemical) & antihypertensive (functional)

10
Q

Prazosin trade name

A

Minipress

11
Q

Prazosin expected effect

A

blocks alpha mediated vasoconstriction of adrenergic receptors, inducing peripheral vasodilation

12
Q

why use Prazosin

A

hypertension

13
Q

Prazosin dosages

A

1mg BID or TID up to 20mg/ day in divided doses. Usual range 6-15mg/ day (some may need 40mg/ day)

A

PO

15
Q

pancreatitis

16
Q

Prazosin nursing considerations

A
assess:
- hypertension
- weight, I & O, edema
teach:
- change positions slowly to prevent orthostatic hypotension
- no OTC meds, or alcohol
- do not discontinue abruptly 
- fainting can occur after 1st dose, take 1st dose at bedtime, full effect takes 4-6 week, no driving/ operating machinery until 4 hours after 1st dose

Hytrin, Zayasel

18
Q

Terazosin drug classification

A

functional: alpha blocker/ antihypertensive
chemical: adrenergic blocker

19
Q

Terazosin expected effect

A

decrease total vascular resistance by blocking alpha receptors (to decrease BP)

20
Q

why use terazosin

A

hypertension, benign prostatic hyperplasia

21
Q

terazosin dosages

A

BPH: 1mg/ day, can increase to 5-10mg; max 20mg
hypertension: 1mg PO, max 20mg/day

22

A

PO

23
Q

terazosin adverse effects

A

nausea, dizzy, drowsy, orthostatic hypotension, blurred vision, dyspnea, edema

24
Q

terazosin nursing implications

A

urinary patterns: hesitancy, freq, dysuria, urgency, uric acid levels
hypertension: crackles, dyspnea, orthostatic BP, jugular vein
therapeutic response: lower BP, edema, less BPH symptoms
- do not drive machinery 4 hours after, fainting occur with first dose
- do not discontinue abruptly, no alcohol
- rise slowly
- for ^BP continue with regular diet & exercise
