How does PCP affect the central nervous system?
Phenycyclidine (PCP) produces many profound effects in the central nervous system. PCP has numerous behavioral and neurochemical effects such as inhibiting the uptake and facilitating the release of dopamine, serotonin, and norepinephrine. PCP also interacts with sigma, mu opioid, muscarinic, and nicotinic receptors.
Does PCP cause nystagmus?
A large case series demonstrated nystagmus in 57% of patients with PCP intoxication, although smaller studies have found an incidence of 85% or higher. Many CNS depressants can produce nystagmus when taken in high doses; however, the patient is generally sedated when nystagmus is observed.
What neurotransmitters does PCP effect?
PCP affects multiple neurotransmitter systems in the brain. It inhibits the reuptake of dopamine, norepinephrine, and serotonin. It also inhibits the action of glutamate by blocking NMDA receptors, which are responsible for pain sensation, emotions, learning, and memory functions.
What are the long term effects of dextromethorphan?
Taking a lot of DXM causes hallucinations and out-of-body sensations similar to the ones caused by drugs like ketamine and PCP. These effects can last as long as 6 hours. DXM also can make users have trouble controlling their limbs and cause blurred vision, slurred speech, dizziness, and impaired judgment.
Who should not take dextromethorphan?
do not take dextromethorphan if you are taking a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate), or if you have stopped taking an MAO inhibitor within the past 2 weeks.
How does dextromethorphan affect the brain?
As NMDA receptor antagonists, dextrorphan and dextromethorphan inhibit the excitatory amino acid and neurotransmitter glutamate in the brain. This can effectively slow, or even shut down certain neural pathways, preventing areas of the brain from communicating with each other.
What are barbiturates side effects?
According to MedicineNet, potential side effects of barbiturates include:
- Lightheadedness.
- Onset of dizziness.
- Sedative effects.
- Nausea.
- Abdominal pain.
- Vomiting.
How do barbiturates make you feel?
Barbiturates are a group of drugs that have calming effects on the body. They can produce effects similar to those of alcohol, ranging from mild relaxation to an inability to feel pain and loss of consciousness.
Does dextromethorphan raise your heart rate?
At high doses, DXM can produce psychedelic symptoms including mania, panic, extreme agitation, and hallucinations. Dextromethorphan poisoning can also cause slow breathing, fast heart rate, increased blood pressure, psychosis (losing contact with reality), seizures, coma, and death.
