Study Notes
Phenytoin and Carbamazepine: Pharmacological Aspects and Nursing Implications
- Phenytoin stabilizes neuronal membrane by delaying sodium influx, used to control tonic–clonic seizures, psychomotor seizures, and nonepileptic seizures
- Caution needed in older adults due to altered albumin levels, renal or hepatic impairment causing drug displacement
- IV administration of phenytoin can lead to cardiovascular collapse, requiring careful monitoring
- Common adverse effects of phenytoin include CNS and GI tract issues, long-term use may lead to increased risk of osteoporosis
- Contraindications to phenytoin include hypersensitivity to hydantoins, caution in patients with specific conditions
- Several medications interact with phenytoin, affecting its effectiveness and absorption of folic acid, calcium, and vitamin D
- Injectable solution of phenytoin is highly irritating to tissues, special techniques needed for IV administration
- Nurse assesses for therapeutic and adverse effects, including absence of seizures and presence of hypersensitivity reactions
- Patient teaching guidelines for phenytoin include taking the drug as prescribed, maintaining good oral hygiene, and using contraception
- Carbamazepine is administered orally, with slow onset of action, and induces liver enzymes to increase metabolism
- Mechanism of action of carbamazepine is not fully understood, used to prevent partial seizures with complex symptoms
- Like phenytoin, carbamazepine crosses the placenta and enters breast milk, requiring caution in pregnant and breastfeeding women
