Unit 4 Drugs in Random Order Flashcards
(112 cards)
Bevacizumab
Tx: Cancer
Mech: blocks VEGF
Prevents Vascular epi. growth factor from binding to receptor
Tumor can only grow w/ blood supply-this blocks it
_Beave_rs are _veg_etarians
Beva-cizumab–VEGF
Dactinomycin
Tx: Cancer
Mech: Intercalates w/ DNA and interferes w/ mRNA synth
Tripelennamine
First gen H1 blocker
Tx: Sedative, local anesthetic effect
Pharmacokinetics: Slightly lipid soluble, not ionized→Gets into CNS
Toxicity:
- High TI
- But suicide attempts b/c readily available
- Interactions w/ other CNS depressants
- Anti-muscarinic effects
Fexofenadine
Second gen H1 blocker
Pharmacokinetics: Ionized in blood so fewer CNS effects
Don’t cause drowsiness
Not metab by P450
Toxicity:
- High TI
- But suicide attempts b/c readily available
- Anti-muscarinic effects
Prednisone
Tx: Asthma
DOC for prophylaxis
Mech: Bind intracellular receptor→altered DNA transcription
Activate receptor
Increase lipocortin→inh. synth of phospholipase A2 (precursor of prost and leukotriene)
Route: Not inhaled
SE:
- Infections (esp mouth)-thrush
- Dysphonia (diff. speaking)
- Systemic effects
Abatacept
Tx: RA
Immunosuppressant
Mech: binds to and inh. CD80, CD86 receptors
Affects T cell activation
ABatacept CD80+86 receptors
_A_batacept for _A_rthritis
Ibritumomab
Tx: Cancer
Mouse MAB
Severe infusion rxn
Sulindac
NSAID
Acetic acid derivative
Tamoxifen
Tx: Cancer
Mech: Blocks estrogen receptor
SE:
- Cataracts
- Retinal changes
Tammy is as big as an ox because her estrogen receptor is blocked. She’s obsessed w/ Ron Swanson and has CRazy eyes
Tamoxifen blocks estrogen receptor. Side effects associated w/ eyes: Cataracts and Retinal damage
Topotecan
and irinotecan
Tx: Cancer
Mech: inhibits topoisomerase 1
- You know its a topoisomerase inhibitor but which one?*
- Add the first letter of one vs two to the front. If it makes sense it’s correct*
- ttopotecan vs otopotecan*
- **O-topotecan so topoisomerase One***
Flutamide
and other “lutamides”
Tx: Cancer (prostate)
Mech: Blocks androgen receptor
Androgen receptor inside cell
Some tumors are hormone dependent
- Careful:*
- Flunomides-inh dihydroorate DH*
- Flutamides-block androgen receptor*
Other NSAIDs
_Pyr_os _ne_ed _e_xcess _f_ire
_Pyr_oxicam _n_abumetone _e_todolac -_f_enac
6-mercaptopurine
Tx: Cancer
Mech: Converted in cell to an analog that inhibits several enzymes needed for purine synth
Prodrug–purine analog
- Azathioprine=immunosuppressant prodrug. *
- Gets converted into 6-mercaptopurine.*
- Used for Chron’s, RA, and transplants*
Acetic acid derived NSAIDs
Double A (Aaron) slobbers into titties
Acetic Acid: Sulindac indomethacin tolmetin
Methotrexate
Tx: DOC early tx of RA
Used more as immunosuppressant than anti-cancer drug
DMARD-Disease modifying anti-rheumatic drug
Actually stops progression of RA rather than just treat symptoms
Mech:
- Analog of Folic Acid
- Inh. enzyme: Dihydrofolate reductase
- PABA→Folic acid⇒Dihydrofolic acid⇒tetrahydrofolic acid
- ⇒ indicate where DHFR works
- Inh. mammalian cell division
- Inh. lots of folic acid dependent processes, especially in cells w/ rapid turnover (at high doses):
- GI
- Fetal development
- Blood cells
- Immune cells more susceptible than above though
- Inh. lots of folic acid dependent processes, especially in cells w/ rapid turnover (at high doses):
Clemastine
First gen H1 blocker
Tx: Motion sickness, sedative
Pharmacokinetics: Slightly lipid soluble, not ionized→Gets into CNS
Toxicity:
- High TI
- But suicide attempts b/c readily available
- Interactions w/ other CNS depressants
- Anti-muscarinic effects
Promethazine
First gen H1 blocker
Tx: Strong sedative, strong anti-emetic
Related to anti-psychotic drugs
Pharmacokinetics: Slightly lipid soluble, not ionized→Gets into CNS
Toxicity:
- High TI
- But suicide attempts b/c readily available
- Interactions w/ other CNS depressants
- Anti-muscarinic effects
Chlorpheniramine
First gen H1 blocker
Tx: Does not cause as much sedation
Pharmacokinetics: Slightly lipid soluble, not ionized→Gets into CNS
Toxicity:
- High TI
- But suicide attempts b/c readily available
- Interactions w/ other CNS depressants
- Anti-muscarinic effects
Cortisone
+
Hydrocortisone
Immunosuppressive potency=1

Ergotamine
Dihydroergotamine
Tx: Migrane
Mech: Partial 5HT receptor agonist
Can affect adrenergic and dopaminergic receptors
Useful in initial stages
SE:
- Ergotism=excess of ergot alkaloids→St. Anthony’s Fire
