CLASIFICACIÓN DE LAS DROGAS SEGÚN SUS EFECTOS FARMACOLÓGICOS
Classification of Drugs Based on Pharmacological Effects
Overview of Drug Classification
- The video discusses the classification of drugs according to their pharmacological effects, categorizing them into three main types: depressants, stimulants, and hallucinogens.
Depressant Drugs
- Depressants alter behavior and vital functions by decreasing the central nervous system's capacity, leading to relaxation, sedation, and sleep.
- Examples include alcohol, opioids, and sedatives. They can cause euphoria and disinhibition but ultimately lead to sedation.
- Effects on the body include slurred speech, impaired coordination, altered time perception, decreased reflexes, somnolence, behavioral changes, coma in extreme cases.
Stimulant Drugs
- Stimulants excite brain cell functions and other bodily systems by accelerating the central nervous system and increasing alertness.
- Common examples are cocaine, nicotine, amphetamines, and synthetic drugs. They can induce euphoria and energy but may also lead to insomnia.
- Physiological effects include increased dopamine transmission in pleasure centers of the brain; symptoms may involve mood swings, loss of appetite, hyperactivity, anxiety, insomnia.
Hallucinogenic Drugs
- Hallucinogens alter chemical transmission in brain centers related to perception (vision, hearing).
- These drugs distort reality perceptions; examples include LSD and psilocybin mushrooms.
