Hi I am preparing for neurosurgery and I want few things of neuropharmacology with antibiotics used in neurosurgery anti epileptics in neurosurgery anti edema agents , chemotherapy agents in neurosurgery and give me drug class, mechanism of action, side effects, special points and try to add as much as images overall and also use standard books Also give some imp drugs of neurology and also add doses of all drugs for different condition and different age grps
mannitol osmotic therapy cerebral edema mechanism
antiepileptic drugs mechanism of action neurosurgery
temozolomide glioblastoma chemotherapy mechanism
antibiotic prophylaxis neurosurgery cefazolin vancomycin blood brain barrier
dexamethasone corticosteroid brain tumor edema mechanism
Parkinson disease drug treatment dopamine levodopa carbidopa mechanism
hypertonic saline intracranial pressure ICP management
neurosurgery pharmacology antibiotics antiepileptics anti-edema doses 2024 standard guidelines
bevacizumab anti-VEGF brain tumor angiogenesis inhibitor
status epilepticus treatment algorithm lorazepam phenytoin levetiracetam valproate
multiple sclerosis disease modifying drugs interferon natalizumab
What's Inside
📋 5 Major Sections:
-
Antibiotics in Neurosurgery — Cefazolin (prophylaxis), Vancomycin (MRSA/post-op infection), Meropenem (Gram-negative meningitis), Metronidazole (brain abscess), Ceftriaxone (bacterial meningitis), Linezolid (VRE/refractory MRSA)
-
Antiepileptics — Levetiracetam ⭐ (preferred peri-op AED), Phenytoin/Fosphenytoin, Valproate, Lacosamide, Carbamazepine, plus the full Status Epilepticus 3-tier escalation protocol with time-based doses
-
Anti-Edema Agents — Mannitol (acute ICP — 0.25–1 g/kg IV), Hypertonic Saline (3% and 23.4%), Dexamethasone (vasogenic edema/tumor — NOT for TBI/cytotoxic edema) with critical contraindications
-
Chemotherapy — Temozolomide (Stupp protocol — 75 mg/m² concurrent, 150–200 mg/m² adjuvant), Lomustine, Carmustine/Gliadel wafer, Bevacizumab (anti-VEGF), Tumor Treating Fields, plus targeted therapy for brain metastases
-
Important Neurology Drugs — Parkinson's (Levodopa/Carbidopa, DA agonists, MAO-B inhibitors, Amantadine), MS (Natalizumab, Ocrelizumab, IFN-β, Fingolimod), Migraine (triptans, gepants, ditans, CGRP mAbs), Myasthenia, Alzheimer's, Neuropathic pain, Spasticity
⭐ Key Exam Points to Remember:
- Levetiracetam > Phenytoin in neurosurgery (no enzyme induction, no CYP interactions)
- Mannitol — stop if osmolar gap >20 or serum osm >320
- Dexamethasone CONTRAINDICATED before PCNSL biopsy ("vanishing tumor")
- MGMT methylation = better TMZ response
- Bevacizumab — hold 4–6 weeks perioperatively (wound healing)
- Ceftriaxone + Dexamethasone (before antibiotics) for bacterial meningitis
