Study Notes

Antianxiety and Hypnotic Drugs

Flurazepam (Dalmane), Temazepam (Restoril), Triazolam (Halcion), Nitrazepam (Mogadon), Oxazepam (Serax) are examples of antianxiety and hypnotic drugs.
Short-acting sedative-hypnotic sleep agents, such as Zopiclone (Imovane), are used for sleep.
Melatonin receptor agonists, like Buspirone hydrochloride (Bustab), are also used for anxiety.

Antidepressant Drugs

Tricyclic antidepressants (TCAs) include Nortriptyline hydrochloride (Aventyl, Norventyl), Amitriptyline hydrochloride (Elavil, Levate), and Imipramine hydrochloride (Impril).
Selective serotonin reuptake inhibitors (SSRIs) include Fluoxetine hydrochloride (Prozac), Paroxetine hydrochloride (Paxil), Citalopram hydrobromide (Celexa), Escitalopram oxalate (Cipralex), Fluvoxamine maleate (Luvox), and Sertraline hydrochloride (Zoloft).
SSRIs work by allowing more serotonin to be available at the synaptic gap.

Mood Stabilizers

Lithium carbonate (Carbolith, Lithane, Lithmax) is used to treat bipolar and other mental health disorders.
Anticonvulsant drugs, such as Valproate (available as sodium divalproex and valproic acid [Depakene]), Carbamazepine (Tegretol), Lamotrigine (Lamictal), Gabapentin (Neurontin), Topiramate (Topamax), and Oxcarbazepine (Trileptal), are also used to treat mood disorders.

Antipsychotic Drugs

First-generation antipsychotic drugs, also known as conventional or typical antipsychotics, are strong antagonists that reduce dopamine transmission by blocking D2 receptors.
Examples include Chlorpromazine (Thorazine), Haloperidol (Haldol), and Perphenazine (Trilafon).
Second-generation antipsychotic drugs, also known as atypical antipsychotics, produce fewer extrapyramidal side effects (EPS) and target both negative and positive symptoms.
Examples include Clozapine (Clozaril), Risperidone (Risperdal), Quetiapine fumarate (Seroquel), Olanzapine (Zyprexa), Ziprasidone hydrochloride monohydrate (Zeldox), Paliperidone (Invega), and Paliperidone palmitate (Invega Sustenna).
Third-generation antipsychotic drugs, such as Aripiprazole (Abilify), are dopamine stabilizers.

Other Drugs

Methylphenidate hydrochloride (Biphentin, Concerta, Ritalin) and Dextroamphetamines, such as amphetamine aspartate monohydrate (Adderall XR), are used to treat attention deficit hyperactivity disorder (ADHD).
Donepezil hydrochloride (Aricept), Galantamine hydrobromide (Reminyl), Rivastigmine hydrogen tartrate (Exelon), and Memantine hydrochloride (Ebixa) are used to treat Alzheimer's disease.

Case Study

Ursula's history of side effects and compliance issues suggest that she has taken an antipsychotic, initially a first-generation agent, which caused motor abnormalities, and then a second-generation product, which caused weight gain due to appetite stimulation.
The second-generation antipsychotic's side effects include weight gain, which is affecting Ursula's self-image.
