Study Notes
CNS Stimulants
-
Classification
- Divided into respiratory stimulants (analeptics) and psychomotor stimulants.
Respiratory Stimulants (Analeptics)
-
Definition
- Drugs that stimulate the depressed respiratory center (RC).
-
Specific Analeptics
- Naloxone and Nalorphine: Treat opiate-induced respiratory depression.
- Flumazenil: Used for benzodiazepine toxicity.
-
Non-specific Analeptics
-
Direct RC Stimulation:
- Examples include xanthines such as caffeine and theophylline, and drugs like Ethamivan and Heptamino.
- These antagonize GABA-mediated respiratory depression.
-
Indirect RC Stimulation:
- Examples include nicotine and lobeline, which stimulate RC indirectly by activating chemoreceptors in the carotid body.
-
Combined Mechanisms:
- Drugs like Nikethamide and Doxapram stimulate the RC both directly and indirectly.
-
Direct RC Stimulation:
-
Therapeutic Uses
- Indicated for respiratory depression from various causes (e.g., post-anesthesia, CNS depressants, COPD, premature infants).
-
Adverse Effects
- May cause tachypnea, tachycardia, hypertension, and at high doses, convulsions.
-
Contraindications
- Avoid in patients with epilepsy, severe hypertension, arrhythmias, ischemic heart disease, thyrotoxicosis, and severe bronchial asthma.
Psychomotor Stimulants
-
Definition
- Drugs that induce euphoria and increased motor activity.
-
Classification
- Amphetamines: Stimulants that enhance catecholamine activity.
- Cocaine: Inhibits tissue uptake of catecholamines, produces effects similar to amphetamines, and is used topically as a local anesthetic (in eye drops).
-
Xanthines: Refer to previous respiratory pharmacology discussions.
Psychotomimetic Drugs (Hallucinogens)
-
Definition
- Drugs affecting thought, perception, and mood without impacting motor functions.
-
Clinical Applications
- Largely lacking; significant relevance to drug abuse.
-
Examples and Mechanisms
- LSD (Lysergic acid diethylamide): Stimulates central 5-HT receptors, leading to hallucinations and delusions akin to acute schizophrenia.
- Cannabis (hashish, marijuana): Acts on cannabinoid receptors (CB1) in the CNS, causing altered judgment of time and place, along with dream-like experiences. Does not cause physical dependence but can lead to psychological dependence.
