What MUST we give to patients taking isoniazid in order to prevent seizures and CNS affects due to pyridoxine deficiency?

Vitamin B6 (Pyridoxine)

New cards
13

Which allergic reaction can be caused from isoniazid?

Lupus like syndrome (butterfly rash)

New cards
14

Rifampin is considered a CYP450 INDUCER, what could that mean for patients taking long term HIV meds or women taking oral contraceptives?

Those meds will be excreted and metabolized much much quicker leading to low levels of them in the body

New cards
15

What is a side affect of rifampin that we must warn our patients about?

HINT: has to do with secretions

Warn them that their tears, sweat, and urine could turn orange

New cards

Why would we ever use methylxanthines such as theophylline in real life?
-Theophylline is a phosphodiesterase inhibitor btw

To treat bad status asthmaticus
NOTE: can cause arrhythmias and convulsions (not a good drug tbh)

New cards
34

Good reduction in triglycerides
Good at raising HDL

NOTE: Fibrates activate PPAR-alpha --> lowers TG
and

New cards
52

If we have a patient with a familial history of just high triglycerides or low HDL, which drug class would be of choice?

Fibrates

New cards
53

How about those with gallbladder disease?

No and No

New cards
55

What's the purpose of bile action sequestrants (resins)?
How does it reduce LDLs?

They bind to bile acids in the GI system and prevent the recirculation of cholesterol, excreting it in the feces

--> This causes the liver to secrete more bile acids and make more LDL receptors --> lowering LDLs

New cards
56

Can we use bile action sequestrants for pregnancy?

Yes!! Does not get absorbed

Note: GI upset is bad, really depends on the patient's choice

New cards
57

Does increasing the dose of bile acids sequestrants help make it more effective?

Nope, just increases the side effects

Within 1 hr of a meal

New cards
59

What can bile acid sequestrants increase?

Triglycerides
Not good for those who already have high triglycerides

New cards
60

We either have the patient take the cardio meds 1 hour before taking the Bile acid sequestrant
OR
Have them take the cardio meds 4 hours after taking the bile acid sequestrant

New cards
61

How does Niacin work?

Decreases hepatic production of VLDL and apo B
--> decreases Triglycerides

Nope, advise not too due to the flushing

New cards
66

Atorvastatin (CYP450/ GRAPEFRUIT JUICE)
Rosuvastatin

New cards
68

How do loop diuretics work?

Name some adverse affects for Loop diuretics?

Hypokalemia
Hyperglycemia
Hyperuricemia
Ototoxicity
Azotemia (BUN increases)

New cards
76

Why would we not want to give NSAIDS with patients on diuretics?

NSAIDS block prostaglandin which constricts the afferent arteriole to the glomerulus, thus reducing GRF and urine output. --> counteracts diuretics

New cards
77

Where do thiazide diuretics work in the kidney?
What transporter do they affect?

Work in the distal tubule
Blocks sodium/chloride channel

New cards
78

What is a BIG difference we see in electrolytes when we compare thiazide diuretics vs Loop diuretics?

Thiazide diuretics hold onto CALCIUM!! (less calcium excretion)

NOTE: GOOD for those experiencing calcium kidney stones because the body will reabsorb it from the lumen (the body can handle high calcium levels)

New cards
79

What diuretic should we give to those experiencing chronic kidney stones?

Thiazide Diuretics

New cards
80

What is the chronic use of thiazide diuretics?

To decrease sodium retention leading to less vasoconstriction in the arteriole walls

How about our serum (blood) pH to be?

Increases in urine (more alkaline)
Decreases in blood (metabolic acidosis)

New cards
90

What CNS condition can carbonic anhydrase treat?

Epilepsy, because carbonic anhydrase inhibitors make the blood more acidic which reduces seizure risk

New cards
91

PRIL

New cards
92

What types of comorbidities can be benefitted from ACE inhibitors?

Which specific angiotensin pathway do ARBS block?

Angiotensin 1

New cards
97

All ARBS end in ..........

Sartan

New cards
98

What are the affects of calcium channel blockers on arterial and venous tone?

Ineffective at decreasing venous tone but work on arterial smooth muscle best
--> This can decrease afterload and have no effect on preload

New cards
99

Which types of calcium channel blockers work on the myocytes of the heart and which do not?

Non-DPH works on the heart and slows AV conduction --> (diltiazem and verapamil)
DPH (dihydropyridine) does not affect the heart/AV node
