Study Notes
Tamoxifen
- Tamoxifen is administered orally and metabolized in the liver, producing metabolites with estrogen agonist and antagonist activity.
- The drug is eliminated primarily through fecal excretion.
- Tamoxifen is an inhibitor of CYP3A4 and P-glycoprotein, which can lead to drug-drug interactions.
- Common adverse effects of tamoxifen include hot flashes, nausea and vomiting, skin rashes, vaginal bleeding, and thromboembolism.
- Tamoxifen can also cause vision problems and increases the risk of endometrial cancer.
Classification of HIV Medications
- HIV medications can be classified into four categories: NRTIs (nucleoside reverse transcriptase inhibitors), NNRTIs (nonnucleoside reverse transcriptase inhibitors), PIs (protease inhibitors), and entry inhibitors.
Anticancer Drugs
- Alkylating agents are a type of anticancer drug that includes nitrosoureas.
