Lecture 2 Flashcards
NTRI HIV treatment used in combo with AZT
Lamivudine
NTRI guanosine analog for HIV treatment in children and adults with intolerance to current modalities of treatment
Abacavir
NTRI First approved nucleotide analog for HIV
Tenofovir
NTRI Lamivudine derivative which inhibits both HIV and DNA reverse transcriptase, once a day agent.
Emtricitabine
NNRTI, lipophylic allows for distribution into breast milk and fetus, increases CD4 count, causes skin rash and elevate hepatic enzymes, 14 day titration
Nevirapine
NNRTI for HIV with 98% binding to albumin, 50/50 excretion urine and feces, skin reactions are common, HA, dizzy (semicircular canals), nausea
Delavirdine
well absorbed orally with 99% coupling to albumin, once per day treatment, vivid dreams, bioavailabiity decreases progressively so dose must be adjusted: Cytochrome p450
Efavirenz
reversible inhibitors of the enzyme responsible for cleavage of viral polyprotein, interferes with CYP isoenzymes, first category used to treat HIV, increase bioavailability in high fat diet (-vir endings), dose dependent on glucose levels, SE atherosclerosis, diarrhea, numbness, many drugs interact and prevent their function
Protease Inhibitors
New class of drugs which impair HIV fusion with Host cell
Viral Fusion Inhibitors
only Viral Fusion Inhibitor for HIV tx, often used with a protease inhibitor.
Enfuvirtide
Term for extending time and relief from symptoms when cancer cannot be cured
Palliation
minimum amount/size of tumor to cause reason to be detected and to have systemic manifetations
1 gram
protocol treatment for Acute Lymphoblastic Leukemia (acronym)
MOPP
Why are cell cycle specific drugs considered toxic?
targeting rapidly diviing cells- GI, Buccal, Bone marrow, Hair follicles : diarrhea, blisters, bleeding, alopecia (not all)
Specific Adverse Effect of Doxorubicin
Cardiotoxicity
Which drug specifically causes pulmonary fibrosis as an adverse effect
Bleomycin
Cancer treatments are often mutagenic, meaning:
secondary neoplasms may arise 10 years or so after original treatment
category of cancer treatments known to have a mutagenic effect:
alkylating agents: cyclophosphamide
True or False: all chemotherapy drugs have the potential for teratogenic effects, treatment is often post-poned until after delivery
TRUE
Category of anti cancer drugs that is cycle specific to the M phase of replication
Microtubule inhibitors
new category of anti cancer drugs that does not have serious side effects because it only targets malignant cells
monoclonal antibodies (-mab)
drugs that impair normal matabolic function during the S phase
Antimetabolites: 5-FU, Gem, 6-mercap etc
Megaloplastic Anemia treatment IV, oral if used for non-oncogenic rheumatoid arthritis/psoriasis, therapeutic applications: ALL and Burkits, Choriocarninoma- curative, osteogenic sarcoma- curative, side effects may be reversed by Leucovorin, pulmonary toxicity while using drug, permanent damage
Methotrexate- folic acid antagonist
Drug used to maintain remission in ALL, Cell cycle specific to S phase, Bone Marrow Depression SE, dose adjustment if taking allopurinol
6-Mercaptopurine
ALL drug with Cross resistance with 6-MP,
6-Thioguanine
Drug used to treat Hairy Cell leuekemia, can cause myelosuppresion, blidness, death
Fludarabine
Drug for Hematalogic malignancies: CLL, non-hodgekins, hairy cell, bone marrow suppression
Cladribine
Drug for Soft tissue carcinomas: colorectal, breast, ovarian, gastric, Hand-Foot Syndrome SE, unlimited by lung exhaling CO2
5- fluorouracil
Oral drug for metastatic breast cancer resistant to paclitaxel, causes Palmar-plantar eythroidesthesia (Hand-Foot in 5-FU)
Capecitabine- which becomes 5-FU
Drug for Acute Myelogenous Leukemia (AML), SE granulocytopenia, can cause altered mental status and seizures at high doses
Cytarabine
