Study Notes
Neuropharmacology Overview
- Focuses on drugs affecting the central nervous system (CNS).
- Aims to alter processes controlled by the nervous system.
- Result in increased therapeutic effects or decreased side effects.
Drug Adaptation Mechanisms
- Tolerance: Reduced response develops with prolonged drug use.
- Physical Dependence: Abrupt drug discontinuation leads to withdrawal syndrome.
Neuronal Functions
- Axonal Conduction: Action potentials travel along neuron axons.
- Synaptic Transmission: Information transfer occurs between neurons and postsynaptic cells.
CNS Stimulants
- Used to treat ADHD by addressing neurotransmitter dysregulation (serotonin, norepinephrine, dopamine).
- ADHD symptoms include impulsivity, restlessness, and concentration difficulties.
- Narcolepsy: Characterized by sudden sleep episodes; treatment includes stimulants like amphetamines and modafinil.
Blood-Brain Barrier
- Restricts entry of drugs into the brain; primarily permits lipid-soluble agents.
- Children exhibit higher sensitivity to CNS drugs compared to adults.
Parkinson's Disease
- Progressive neurodegenerative condition affecting movement.
- Symptoms: Tremors, rigidity, postural instability, bradykinesia.
- Treatment focuses on improving daily activities and alleviating motor symptoms.
Dopaminergic Drugs
- Levodopa: Converts to dopamine; enhances motor control.
- Dopamine Agonists: Activate dopamine receptors directly (e.g., pramipexole, ropinirole).
- Adverse effects: Can include hallucinations and impulse control disorders.
Barbiturates and Anticonvulsants
- Phenobarbital: Effective for various seizure types; potentiates GABA effects.
- Carbamazepine: First-line for partial and tonic-clonic seizures; delays sodium channel recovery.
- Gabapentin: Increases GABA levels; also treats neuropathic pain.
Nursing Process in Neuropharmacology
- Conduct thorough assessments to monitor motor symptoms and potential side effects.
- Track patient compliance and conduct laboratory tests to ensure safety.
- Patient education on medication adherence and potential drug interactions is essential.
Substance Withdrawal
- Alcohol Withdrawal: Symptoms arise within 4-12 hours, peak at 24-48 hours, resolving within 5-7 days unless delirium occurs.
- Opioid Withdrawal: Symptoms present within 1-3 days post-cessation; non-life-threatening but may include agitation and flu-like symptoms.
Detoxification and Maintenance
- Both alcohol and opioid addiction require structured detoxification and long-term abstinence support.
- Continuous evaluation and management of withdrawal symptoms are critical during recovery phases.
