Term | Definition |

Clindamycin | binds to 50S ribosomal subunit and prevents binding of next amino acid; covers Gram + and anaerobes |
Azithromycin | binds to 50S ribosomal subunit and stalls translocation by blocking exit tunnel; covers Gram + and intracellular bacteria, IE prophylaxis |
Moxifloxacin | binds to topoisomerase and fragments DNA; bactericidal, used for respiratory infections with Strep pneumonia and Mycoplasma |
Metronidazole | fragments DNA, narrow spectrum; anaerobic infections and C. diff |

Regular insulin | translocation of GLUT4 receptors to cell surface; fast-acting, peaks in 2-4 hours |
Glimepride and Nateglinide | blocks ATP-dependent K channels to make more insulin; T2DM add-on therapy |
Metformin | lowers hepatic glucose production by lowering glucagon; T2DM first-line therapy and oral cancers |
Acarbose | inhibits alpha-glucosidase so carbohydrates are not absorbed by brush border in intestine; T1&2DM, lowers glucose levels after meals |
Pioglitazone | 'insulin sensitizer'; increases GLUT4 receptors in muscle and adipose tissue and lowers glucagon in liver
-also stores FFA's via PPAR |
Sitaglipin | prolongs GLP-1 action to promote first phase insulin secretion during meals |
Canagliflozin | blocks SGLT2 in kidney to block glucose reabsorption in proximal tubule |

Carbamazepine | selective Na-channel blocker; treats tonic-clonic, focal, and trigeminal neuralgia |
Valproic Acid | Na-channel blocker, weak Ca-channel blocker; multiple seizure disorder, migraines, bipolar disorder |
Ethosuximide | Ca-channel blocker in thalamus; only treats absence seizures, causes bone marrow depression |
Levetiracetam | binds to SV2A so vesicles not released by presynaptic neurons; treats tonic-clonic and focal seizures |
Pregabalin | decreases expression of presynaptic Ca channels; treats focal seizures and chronic pain disorders |
Paclitaxel | promotes microtubule polymerization so cells are arrested in mitosis; cancer drug that is inactivated by CYP450s |
Doxorubicin | inhibits topoisomerase II to fragment DNA; useful for blood cancers and solid tumors but generates ROS's |
Cyclophosphamide | alkylates cell components to damage DNA; used for cancers and transplant rejections (CYP450) |
Methotrexate | inhibits DHFR to block tetrahydrofolate for nucleotide synthesis; used for cancers, arthritis, psoriasis but highly protein bound and displaced by phenytoin and sulfonamides |
5-Fluorouracil | inhibits RNA function and pyrimidine formation; cancer drug |
Tamoxifen | inhibitor and partial agonist of estrogen receptor; for ER+ breast cancers |
Anastrozole | inhibits aromatase that makes estradiol for ER+ breast cancers |
Leuprolide | resembles RnRH cousing surge in LH/FSH and decrease in testosterone; treats prostate cancer |
Cisplatin | cross-links and alkylates DNA; primary drug for treatment of lung cancer |
Trastuzumab | antibody fragment that disrupts HER-2/neu, a receptor that develops in cancers after first line therapy |
Ipilimumab | blocks CTLA4 to activate cytotoxic T-cells; inhibits tumor growth, melanoma but very expensive |
Teriparatide | N-terminal of PTH, increases osteoblast activity; high fracture-risk patients |
Alondronate | BP, disrupts osteoclasts; oral, for osteoporosis |
Zoledronic Acid | BP, disrupts osteoclasts; by injection only and more potent, for bone metastases |
Denosumab | mimics OPG that prevents RANKL from binding to RANK and activating osteoclasts; used for bone metastases pain and hypercalcemia |
L-DOPA:carbidopa | dopamine supplement, crosses BBB; treatment of Parkinson's disease |
Pramipexole | dopamine agonist; for mild PD or adjunctive |
Entacapone | COMT inhibitor, reduces degradation of L-DOPA in periphery so more can get to CNS for PD
-caution with epinephrine |
Selegiline | irreversible MAO-B inhibitor, reduces dopamine degradation in CNS
-caution with epinephrine |
Olanzapine/Clozapine | 2nd generation antipsychotics; alleviates positive and negative symptoms of schizophrenia with fewer side effects |
