Antineoplastic Flashcards
Antimetabolites
Inhibit nuclei acid synthesis(purine, pyramidine)
Compete competitively
Reduce DNA , RNA
Methotrexate
Antimetabolite
Antifolate(inhibit DHF Reductase 2»4)
Resistance, high dose(10x), folinic acid resque
Pneumonia, Nephrotoxicity
Acute, Chronic Ca, Breast lung, Psoriasis, Rhematoid Athritis
Alkylating Agent
CnH2n+1, Transfer alky group to DNA in n7 of guanine
Breakage of DNA Strand or cross linkage, block DNA synthesis
Cyclophosphamide
Alkylating Agent, Prodrug, metabolized by MES
Became Phosphoramide & Acrollin(Haemorrage Cystitis)
Lymphoma, lymphatic leukemia, Ca breast & ovary
Acrollin
By product metabolize of cyclophosphamide
Cause haemorrge cystitis,
lowered by high fluid intake
& bladder irrigation
Using N-Acetylcysteine
Or MESNA (Na 2-Metacaptoethane Sulfonate)
Hormone
Glucocorticod Prednilosone lymphoma n leukimia
Estrogen in prostate n breast in male
Progestogen in endometrial tumor breast n prostate
Androgen in breast cancer female
Pharma-Tamoxifen
Physiology-Testosterone
Cytotoxic Antibiotic
Effect mainly direct to dna
CCNS execpt bleomycin
Free radical generator
Doxorubicine
Cytotoxic Antibiotic
Free radical generator Inhibit nuclic acid syntesis
Used in leukemia and lymphomas and solid tomours
Adrs is cardiotixicity( arythemia and CHF)
Bleomysin
Cytotoxic Antibiotic Free radical generator Use in squamous cell carcinoma, testis n hodgkins disease(lymphoma) Adrs pulmonary fibrosis n pnumonia
Mitotic spindle poison
Microtubule inhibitors
Inhibit metaphase by binding to tubulin
Used in acute lymphoma leukemia and sarcoma and willms tumor
Vesicant.
Adrs locallise tissue damage, thrombophlebitis, parasthesia,
muscle weakness, neuromuscular effect
Vincristine and vinblastine
Mitotic spindle poison
From vinca alkalloids , periwinkle plants
Aim of chemotheraphy
Curative- Hodgkin’s lymphoma
Palliative - In allevation of sign & symptom
Reduce intensity of manifestation
Dysphagia
Adjuvant - Addition to surgery or radiation to completely eliminate remote micro metastasis
General Adr AN
Nausea & vomiting Bone marrow & lymphoreticular system depression Damage to GIT lining & mucosa surface Hair bulb damage Delayed wound healing Fx on germ cell Various organ damage Secondary cancer Hyperuricemia Local toxicity
Alternative treatment cancer
Surgical excision
Irridiation
Chemotheraphy
