Adverse effects and management – This book covers the entire syllabus of “Pharmacology” prescribed by BNMC- for diploma in nursing science & midwifery students. We tried to accommodate the latest information and topics. This book is an examination setup according to the teachers’ lectures and examination questions.
At the end of the book, previous questions are given. We hope in touch with the book students’ knowledge will be upgraded and flourish. The unique way of presentation may make your reading of the book a pleasurable experience.

Management of CNS depressant overdose patient.
Management for CNS depression or CNS depressant overdose depends on the substances involved.
➤ Some CNS drugs have antidotes that can reverse their effects. These include Naloxone for opioid overdoses and Flumazenil for overdoses of benzodiazepine.
➤ A person may need emergency care if they are unaware that they are experiencing a CNS depressant overdose, especially after accidentally misusing their medication or due to a medical problem.
➤ Anyone witnessing signs of CNS depression or an overdose in another person should call the emergency services or local poison control center for guidance.
➤In these cases, treatment may include:
- Monitoring the person’s breathing and heart rate.
- Giving oxygen via an oxygen mask or respirator
- Administering stimulant drugs to increase a person’s heart rate
Central Neurotransmitters
A vast number of neurotransmitters are identified in the CNS. The most common neurotransmitters in the CNS are
- Acetylcholine
- Dopamine
- GABA
- Glutamate
- Glycine
- 5-HT (serotonin)
- Norepinephrine
- Histamine
- Opioid peptides
- Achykinins
- Endocannabinoids
