Introduction
Pharmacology
The broad study of drugs and their effects on the entire body,
including cardiovascular, digestive, and immune systems.

Psychopharmacology
It is a professionally recognized specialty field dedicated to the
study and therapeutic use of psychotropic medication, in
addition to traditional psychological interventions, for the
treatment of mental disorders and the promotion of overall
patient health and well-being.

Key Focus:
Unlike general pharmacology, which studies effects across the
body, psychopharmacology focuses on how medications target
specific neurotransmitters and neural circuits in the brain and
how they further influence mental health and behavior.
Psychotropic
Medication
“Psycho” relates to the mind or brain

“Tropic” means to be attracted to or turn toward

Psychotropics are defined as a chemical substance


that crosses the blood-brain barrier, acts on the central
nervous system, and affects consciousness, cognition,
mood, and behavior. (Thomas A. Ban)
Characteristics of an Ideal
Psychotropic Drug
An ideal psychotropic drug should have the following characteristics
(Hollister, 1983):

1. It should cure the underlying pathology causing the disorder or


symptom(s) under focus, so that the drug can be stopped after sometime.
2. It should benefit all the patients suffering from that disorder.
3. It should have no side-effects or toxicity in the therapeutic range.
4. It should have rapid onset of action.
5. There should be no dependence on the drug and no withdrawal
symptoms on stopping the drug.
6. There should be no tolerance to the drug so that same dose is effective
for long duration of time.
7. It should not be lethal in overdoses.
8. It can be given in both inpatient and out patient settings.

Understanding how the drugs function:
To understand how the drug effects our body, it is important to know the
functions of the various neurotransmitters (chemical messengers that carry
signals between neurons, muscles, and glands) in our body:
Before understanding drug function:

Receptors: protein molecules including enzymes, transporters and ion


channels where a,
Ligand: (specific endogenous neurotransmitter/hormone or an external
pharmacological agent (drug)) binds to, resulting in a cellular response
Understanding the effect of drug:
There are two major interactions that occur when a drug
(ligand) exerts its effects onto a receptor:

Agonist (enhance)
Antagonists (block)

Agonists: Drugs that bind to and activate receptors, mimicking


the action of natural neurotransmitters.
They are classified into:
Full Agonists: Produce a maximal biological response.
Partial Agonists: Bind to the same receptor but elicit a
weaker response.
Inverse Agonists: Bind to the receptor and produce the
opposite effect, reducing baseline receptor activity.

Antagonists: Drugs that bind to receptors without activating


them, blocking the action of agonists or natural
neurotransmitters, thereby inhibiting their effects.

Concept:
Pharmacodynamics
Effects of these drugs on the body:
Dose-Response Curve: The dose – response curve plots the effects of a drug against its plasma
concentration.

Potency: Potency refers to the ratio of drug dosage to clinical effect.


Efficacies: capability of the drug to elicit maximal beneficial response at their respective optimal dosages.
Key Elements of Pharmacodynamics
Therapeutic index: A ratio that compares the blood concentration at which a drug becomes toxic
and the concentration at which the drug is effective.
The larger the therapeutic index (TI), the safer the drug is. If the TI is small (the difference between the
two concentrations is very small), the drug must be dosed carefully and the person receiving the drug
should be monitored closely for any signs of drug toxicity.
Key Elements of Pharmacodynamics
Tolerance and Dependance: When a person becomes less responsive to a particular drug with time,
tolerance to the effects of the drug has developed. The development of tolerance can be associated
with the appearance of physical dependence, which is the need to continue taking a drug to prevent
the appearance of withdrawal symptoms.

IMPORTANT TERMS
Indications: Indications refer to the specific medical conditions or
symptoms for which a drug is prescribed.

Contradictions: Contraindications are specific situations or conditions


where a drug should not be used because it may be harmful.

Side effects: These are expected and often mild effects that occur at
therapeutic doses. Side effects may not always require stopping the
medication and are often manageable (e.g., dry mouth, sedation).

Adverse Effects: These are unexpected, harmful effects that may occur
even at therapeutic doses. Adverse effects are more serious and can lead
to complications, requiring drug discontinuation or alternative therapies
IMPORTANT TERMS
PLACEBO-NOCEBO EFFECT:
Placebo is defined as an inert substance that provokes perceived benefits,
whereas,
Nacebo is used when an inert substance causes perceived harm.

The placebo effect occurs when a placebo makes the patient feel better or
improves symptoms. Examples: sugar pills, vitamin capsules, saline injections
etc.
Use of placebo is restricted majorly to clinical trials for conditions such as
depression, somatoform disorders, pain conditions, psychosis, sleep disorders,
asthma, irritable bowel disease.

Though active drugs have significantly better evidence in symptom reduction,


the placebo rates are promising. 30-50% response rates in depression and
anxiety; 7-10% in psychosis.
ANTIPSYCHOTICS
ANTIPSYCHOTICS
Antipsychotics, also known as neuroleptics or major
tranquilizers, are medications primarily used to treat
psychotic disorders such as schizophrenia, bipolar CLASSIFICATION
disorder, and other mental health conditions.

ANTIPSYCHOTICS
Mechanism of Action
Dopamine Pathway:
Both classical and atypical antipsychotics primarily act by blocking dopamine
D2 receptors, which helps reduce psychotic symptoms.

Serotonin Receptor Activity:


Atypical antipsychotics also affect serotonin receptors (specifically 5-HT2A
receptors), which helps alleviate negative symptoms of schizophrenia and
reduces the likelihood of extrapyramidal side effects.

Additional Effects:
Some antipsychotics also have anticholinergic, anti-alpha adrenergic, and
antihistaminic actions, which contribute to their therapeutic and side effect
profiles.

Types of Different Drugs
Classical (Typical) Antipsychotics:
• Chlorpromazine: Known for strong sedation and anticholinergic effects.
• Haloperidol: High potency, used frequently for acute psychotic agitation.
• Trifluoperazine: Effective but has a high risk of extrapyramidal effects.

Atypical (Second-Generation) Antipsychotics:


Clozapine: Used for treatment-resistant schizophrenia but requires blood monitoring
for agranulocytosis.
Risperidone: Effective for both positive and negative symptoms; lower EPS risk.

ANTIDEPRESSANTS
ANTIDEPRESSANTS
Antidepressants are medications used to alleviate symptoms of depressive disorders and other
conditions such as anxiety and chronic pain.

Classification: (Based on mechanism of action)


Tricyclic Antidepressants (TCAs): Older antidepressants that block the reuptake of norepinephrine
and serotonin. -> Tetracyclic antidepressants have a slightly different structure and mechanism, are often
considered a tricyclic variant and have fewer side effects.

Selective Serotonin Reuptake Inhibitors (SSRIs): Specifically inhibit serotonin reuptake, widely
prescribed due to fewer side effects.

Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): Block reuptake of both serotonin and


norepinephrine, useful in both depression and chronic pain.

Monoamine Oxidase Inhibitors (MAOIs):Inhibit the enzyme monoamine oxidase, which breaks
down neurotransmitters; effective but require dietary restrictions.

Atypical Antidepressants: These include drugs with unique mechanisms, like mirtazapine and bupropion.

ANXIOLYTICS
ANXIOLYTICS
Anxiolytics (anti-anxiety) are medications designed to reduce symptoms of anxiety,
commonly used to treat generalized anxiety disorder, panic disorder, and other anxiety-
related conditions.

cases.
ANXIOLYTICS
Mechanism of Action
Benzodiazepines:
Enhance the effect of GABA (gamma-aminobutyric acid), the brain’s primary
inhibitory neurotransmitter, leading to reduced neuronal excitability and a calming effect.
SSRIs and SNRIs:
Increase serotonin and norepinephrine levels by inhibiting their reuptake, which
helps alleviate both anxiety and depression over time.
Azapirones (e.g., Buspirone):
Act as a partial agonist at the serotonin (5-HT1A) receptor, providing anxiolytic
effects without sedation or potential for dependence.
Beta-Blockers:
Block the effects of adrenaline on the body, reducing physical symptoms of anxiety like
rapid heart rate and tremors.

MOOD STABILIZERS
MOOD STABILIZERS
Mood stabilizers are medications primarily used to stabilize mood swings,
particularly in bipolar disorder, and to prevent both manic and depressive episodes

Classification and Mechanism

Lithium:
The first mood stabilizer and a highly effective treatment for mania and bipolar disorder.
Although the exact mechanism is unclear, lithium is thought to affect neurotransmitter balance
and intracellular signaling, influencing mood regulation. It may inhibit inositol
monophosphatase and modulate serotonin and dopamine levels.

Atypical Antipsychotics:
Certain atypical antipsychotics (e.g., quetiapine, aripiprazole) have mood-stabilizing effects and
are used in bipolar disorder.
Affect both dopamine and serotonin receptors, which helps balance mood and manage manic
symptoms.

MISCELLANEOUS
DRUGS
Miscellaneous psychiatric drugs refer to medications that don’t
fit neatly into the main categories (antipsychotics,
antidepressants, anxiolytics, mood stabilizers) but are still used
to treat specific psychiatric symptoms.

•Examples:
• Stimulants: (e.g., Methylphenidate, Amphetamines)
Primarily used for attention-deficit/hyperactivity disorder (ADHD).
• Alpha-2 Adrenergic Agonists: (e.g., Clonidine,
Guanfacine)
Used for ADHD and managing symptoms of PTSD.
• Cognitive Enhancers: (e.g., Donepezil, Rivastigmine)
Primarily prescribed for dementia-related cognitive impairment.
• Others:
Includes drugs with specific or off-label uses, like prazosin for PTSD
nightmares.
ADVANCES IN
PSYCHOPHARMACOLOGY
• Third-Generation Antipsychotics: Medications like cariprazine and
brexpiprazole represent newer antipsychotics that act as partial dopamine agonists,
providing effective symptom control with potentially fewer side effects than previous
generations.
• Ketamine for Depression: Traditionally an anesthetic, ketamine and its
derivative esketamine have shown rapid-acting effects in treatment-resistant
depression, working within hours compared to traditional antidepressants that take
weeks.

Why It Matters:
These innovations address treatment-resistant cases and symptom profiles that
previous drugs have not managed well, providing more options for complex or
refractory cases. The development of these therapies underscores the need for mental
health professionals to stay informed about research advances to offer the best, most
current treatments to patients.
