Study Notes
Anxiety Disorders
- Generalized Anxiety Disorder (GAD) involves neurotransmitters norepinephrine and serotonin.
- The Excitatory-Inhibitory Neurotransmitter Theory illustrates how norepinephrine increases anxiety while GABA neurons decrease it.
Treatment Strategies for GAD
- Psychotherapy is the primary non-pharmacological treatment.
- Medications include:
- SSRIs (Selective Serotonin Reuptake Inhibitors)
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)
- TCAs (Tricyclic Antidepressants)
Common Medications for GAD
- SSRIs:
- Citalopram (Celexa) - Side effects include sleep disturbances.
- Escitalopram (Lexapro) - Can cause anxiety.
- Fluoxetine (Prozac) - Possible diarrhea.
- Paroxetine (Paxil) - May lead to sexual dysfunction and hyponatremia.
- Sertraline (Zoloft) - Risk of bleeding.
- SNRIs:
- Venlafaxine (Effexor) - Side effects include nausea and dry mouth.
- Desvenlafaxine (Pristiq) - Potential for constipation and hypertension.
- Duloxetine (Cymbalta) - Risk of sexual dysfunction and hyponatremia.
- TCAs:
- Amitriptyline (Elavil) - Known for anticholinergic effects.
- Nortriptyline (Pamelor) - Can cause drowsiness and weight gain.
Temporary Anxiolytics for GAD
- Medications include:
- Alprazolam (Xanax)
- Clonazepam (Klonopin)
- Diazepam (Valium)
- Lorazepam (Ativan)
- Buspirone (Buspar)
- Hydroxyzine (Atarax, Vistaril) - Antihistamine.
Benzodiazepines Overview
- Various benzodiazepines have different onset times and durations of action.
- Many are fast-acting and may cause sedation or have a risk of respiratory depression when combined with opioids or alcohol.
Neurotransmitters Involved in ADHD
- Norepinephrine and dopamine are key neurotransmitters in Attention Deficit Hyperactivity Disorder.
ADHD Medications
- CNS Stimulants:
- Amphetamine-Dextroamphetamine (Adderall)
- Lisdexamfetamine (Vyvanse)
- Methylphenidate (Ritalin, Concerta)
- Dexmethylphenidate (Focalin)
- Norepinephrine-Dopamine Reuptake Inhibitor:
- Atomoxetine (Strattera).
Seizures and Epilepsy
- Epilepsy is characterized by two or more unprovoked seizures.
- Seizures may present as convulsions or abnormal movements.
Pathophysiology of Seizures
- Insufficient GABA activity leads to inadequate inhibition, causing excessive neuron firing.
Neurodegenerative Disorders
- Includes Alzheimer’s Disease and Parkinson’s Disease.
- Alzheimer’s involves a loss of acetylcholine neurons, leading to dementia.
- Parkinson’s involves a loss of dopamine neurons, affecting motor control.
Medications for Parkinson's Disease
- Carbidopa-Levodopa (Sinemet, Sinemet CR) - May discolor urine and has nausea as a side effect.
- Pramipexole (Mirapex) - Can cause drowsiness and hallucinations.
- Ropinirole (Requip) - Has nausea and orthostasis as common effects.
Medications for Alzheimer's Disease
- Donepezil (Aricept) - Side effects include nausea and potential QTc prolongation.### COPD and Medications
- Memantine (brand name Namenda) is used for treating confusion.
- Dosage for Memantine should not exceed 5 mg; for patients requiring 10 mg, administration should be twice daily (BID).
- Memantine increases glutamate receptor activities, potentially influencing cognitive functions.
- Common side effects of Memantine include dizziness, headache, and fatigue.
Ophthalmic Agents for Glaucoma
- Glaucoma is characterized by excess intraocular pressure, which can lead to vision loss if untreated.
- Various ophthalmic agents are available for managing glaucoma, some requiring refrigeration.
List of Ophthalmic Agents
- Bimatoprost: Brand name Lumigan; must be stored refrigerated.
- Brimonidine: Brand name Alphagan P.
- Dorzolamide-timolol: Brand name Cosopt.
- Latanoprost: Brand names Xalatan, Xelpros; must be stored refrigerated.
- Timolol: Brand names Timoptic, Betimol, Istalol.
- Travoprost: Brand name Travatan Z; must be stored refrigerated.
