KD Tripathi is not in the library, but I have all the pharmacology content needed. Let me search specifically for the anticancer/alkylating agent sections.

I have Goodman & Gilman and Katzung - both are the gold standard pharmacology references that KD Tripathi is also based on. Let me read the cisplatin sections from Goodman & Gilman and Lippincott (which is closest to KD Tripathi style).

Cisplatin HighYield KDTripathi
PDF Document · PDF
What's inside the PDF (aligned with KD Tripathi style):
| Section | Content |
|---|---|
| Quick Identity | Drug class, chemical name, discovery, FDA approval, cell-cycle phase |
| Mechanism of Action | Step-by-step: Entry (CTR1) → Aquation → DNA adducts → Apoptosis |
| Pharmacokinetics (ADME) | IV only, protein binding >90%, renal excretion, t½, hydration protocol |
| Therapeutic Uses | BEP (testicular 90% cure), ovarian, bladder, H&N, lung, esophageal, radiation sensitizer |
| Adverse Effects | Full table: Nephrotoxicity (dose-limiting), N/V (most severe), ototoxicity, neuropathy, electrolyte wasting, anaphylaxis |
| Resistance Mechanisms | CTR1 downregulation, ATP7A/7B efflux, glutathione, NER, MMR loss |
| Platinum Analogues Comparison | Cisplatin vs Carboplatin vs Oxaliplatin — full comparison table |
| Drug Interactions | Aminoglycosides, taxanes, amifostine, aluminium equipment |
| High-Yield Exam Points | 14 starred exam-ready facts + "RONE + N/V" mnemonic |
| Important Regimens | BEP, MVAC, GC, TP, CF, EP, CAP with their uses |
| Contraindications | Renal failure, ototoxicity, pregnancy, etc. |
Key facts to remember:
- Dose-limiting toxicity = Nephrotoxicity (proximal + distal tubule)
- Most emetogenic drug in oncology - mandatory 5-HT3 + NK1 + dexamethasone pre-medication
- BEP regimen cures 90% of testicular cancers (★ top exam fact)
- Aluminium inactivates cisplatin - plastic/glass equipment only
- Carboplatin dose is calculated by AUC (Calvert formula), not mg/m²
- Oxaliplatin unique toxicity = cold-induced neuropathy (colorectal cancer)
