PsychopharmacologyPsychopharmacology

Definitions

PsychopharmacologyPsychopharmacologyThe scientific study of the actions of substances and how they affect all three domains of human behavior (cognitive, affective, and psycho-motor).

Psycho-pharmacologyBoth naturally occurring as well as manufactured substances are studied because of their psychoactive characteristics.

The basic questions are :What do these substances do?How do they work?

Psychopharmacology

What does it mean for a drug to be PSYCHOACTIVE?

A psychoactive drug, psycho-pharmaceutical, or psychotropic refers to any chemical substance that can migrate across the blood-brain barrier and affect the central nervous system causing changes to brain function. These changes in brain functioning can result in further changes to:

The history of Islamic medicine has deep roots in Azerbaijan. Early man used herbs and vegetation in his first efforts to cure illnesses. The experience he gained during the centuries was passed down generation to generation and developed into folk medicine. With the appearance of writing, the development of oral and written branches of folk medicine became separated. Scientific medicine became based on the written word.

Psychopharmacology

Modern psychopharmacology

Modern psychopharmacology began with the use of psychiatric drugs to treat psychological problems primarily through sedation using opiates and barbituates.

Laudanum (tincture of opium)

Early patent medicines contained opium and were powerful narcotics. These were medicines sold “over the counter”…no prescription or doctor’s order was required.

Psychopharmacology


In the early stages, psychopharmacology was primarily used for sedation.

Psychopharmacology


During the 1950s drugs began to be used for the treatment of mental disorders :

Chlorpromazine for psychoses,

Lithium carbonate for mania,

Tricyclic antidepressants, monoamine oxidase inhibitors,

benzodiazepines, for treatment of depression

Psychopharmacology


Since 1960: Revolution in pharmaceutical research and manufacturing.

1. Better research methods: Placebo-controlled, double-blind studies.

2. Better methods for analyzing blood chemistry

3. Dramatic increase in biochemical brain research into the effects of psychoactive substances on brain functioning.

Psychopharmacology

…but how do drugs work?

Psychopharmacology

Drugs work by Modifying Chemical Signals andchanging the way neurons communicate with each other…..

Psychopharmacology

Psychoactive drugs exert their sensory and behavioral effects almost entirely through action on neurotransmitters, and modifying one or more aspects of synaptic transmission.

Psychopharmacology

Drugs may act by

1) serving as a chemical that triggers the action of a neurotransmitter;

2) Slowing or stopping the production of neurotransmitter;

3) preventing storage of neurotransmitter in the presynaptic vesicle;

Psychopharmacology

Drugs may act by

4) stimulating or inhibiting neurotransmitter release;

5) stimulating or blocking postsynaptic receptors;

6) inhibiting neurotransmission breakdown; or

7) blocking neurotransmitter by the presynaptic neuron.

Psychopharmacology

HormonesA hormone (from Greek ''ὁρμή'' - "impetus") is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

Stimulants increase brain activity.

Commonly used stimulants are caffeine and nicotine. Amphetamine and cocaine are also stimulants. Some stimulants are used recreationally and others, such as anti-depressants, have medicinal purposes and are available by prescription.

3. Opiates: pain killers heroin morphine and codeine

Opiates alleviate painful sensations. Opiates are derived from opium and produce effects by interacting with opiate receptors in the brain. Opium is naturally produced in opium poppies. Codeine and morphine are clinically-administered opiates used to treat pain. The illegal drug heroin is an opiate. Opiates are highly addictive.

Opiates

Psychopharmacology

Psychopharmacology

Opium poppies have been cultivated since at least neolithic times (new stone age). The plant has been grown as a source of food, anesthesia and for ritual purposes.

The archeological record suggests that Sumerian, Assyrian, Egyptian, Indian, Minoan, Greek, Roman, Persian and Arab cultures all made use of opium where it was used primarily for pain relief. Ancient surgeons relied upon opium as an anesthetic during surgery.

Psychopharmacology

4. Hallucinogens PCP, LSD

Hallucinogens are substances that alter the cognition and sensory perception of the user. Marijuana, psilocybin and mescaline are naturally-derived hallucinogens. Such drugs as LSD and ecstasy are synthetic hallucinogens. Unlike other psychoactive drugs, most hallucinogens are not lethal at high doses. Most hallucinogens are classified as Schedule I drugs by the United States, meaning the government deems them unsafe and of no medicinal value.

However, adverse psychiatric reactions such as anxiety, paranoia, and delusions are possible

5. Antipsychotics (Neuroleptics) Treatment of Bipolar disorder, depression, and schizophrenia. These drugs work by inhibiting the reuptake of neurological signals, or inhibiting dopamine within the brain

An antipsychotic (or neuroleptic) is a psychiatric medication used to treat psychosis (delusions or hallucinations) as well as disordered thought (schizophrenia, bipolar disorder)

Side effects (particularly with prolonged use) may include

Shorter life expectancy WeaknessWeight gain motor impairmentDecreased brain volume Repetitive body movementsDiabetes Sexual dysfunction

Psychopharmacology

Antidepressants

Psychopharmacology

AntidepressantsReduce symptoms of mood disorders primarily through the regulation of norepinephrine and serotonin.

Monoamine oxidase inhibitors (MAOIs) are the oldest class of antidepressants. They encourage increased levels of norepinephrine, dopamine, and 5-HT and increase the actions of these neurotransmitters at their receptors. MAOIs have been somewhat disfavored because of their reputation for more serious side effects.

Tricyclic antidepressants (TCAs) work through binding to the presynaptic transporter proteins and blocking the reuptake of norepinephrine or 5-HT into the presynaptic terminal, prolonging the duration of transmitter action at the synapse.

Selective serotonin reuptake inhibitors (SSRIs) selectively block the reuptake of serotonin (5-HT). This increases the availability of 5-HT in the synaptic cleft. The main parameters to consider in choosing an antidepressant are side effects and safety. Most SSRIs are available generically and are relatively inexpensive.
