Medications used to treat depression by altering brain chemistry. Common classes of antidepressants include selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and tricyclic antidepressants.
Anxiolytics #
Medications used to treat anxiety disorders by reducing feelings of anxiety and promoting relaxation. Examples of anxiolytics include benzodiazepines and buspirone.
Attention #
Deficit/Hyperactivity Disorder (ADHD): A neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. Stimulant medications like methylphenidate and amphetamines are commonly used to treat ADHD.

Cholinesterase Inhibitors #
Medications used to treat Alzheimer's disease by increasing levels of acetylcholine in the brain. Common cholinesterase inhibitors include donepezil, rivastigmine, and galantamine.
Depression #
A common mental health disorder characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities. Antidepressants and psychotherapy are primary treatments for depression.
Drug Interactions #
The effects that occur when two or more drugs interact with each other, altering the way they work in the body. Drug interactions can lead to reduced effectiveness, increased side effects, or toxicity.
Dual Diagnosis #
The co-occurrence of a substance use disorder and a mental health disorder in an individual. Treatment for dual diagnosis typically involves addressing both conditions simultaneously.
Evidence #
Based Practice: An approach to healthcare that integrates the best available research evidence with clinical expertise and patient values. Evidence-based practice helps healthcare professionals make informed decisions about patient care.

A severe form of depression characterized by persistent feelings of sadness, loss of interest, and other symptoms that interfere with daily functioning. Treatment for MDD often includes antidepressant medications.
Medication Management #
The process of prescribing, dispensing, and monitoring medications to ensure safe and effective treatment. Medication management involves assessing medication needs, educating patients, and monitoring for adverse effects.
Neurotransmitter #
Chemical substances that transmit signals between neurons in the brain. Common neurotransmitters include serotonin, dopamine, and norepinephrine, which play key roles in mood regulation and other brain functions.
Off #
Label Use: The practice of prescribing a medication for a condition or use that is not approved by regulatory agencies. Off-label use is legal and common in certain situations where there is evidence to support its effectiveness.
Pharmacodynamics #
The study of how medications interact with the body to produce therapeutic effects. Pharmacodynamics involves understanding how drugs bind to receptors, alter biochemical pathways, and influence physiological processes.
Pharmacokinetics #
The study of how the body processes medications, including absorption, distribution, metabolism, and excretion. Pharmacokinetics helps determine the optimal dosing regimen for a medication based on individual patient factors.
