Study Notes
Melatonin
- The highest concentration of melatonin in mammals is found in the pineal gland.
- Melatonin is synthesized from tryptophan by decarboxylase.
- Melatonin is used to relieve nausea and vomiting but may need repeated administrations due to recurring headaches.
- The oral bioavailability of melatonin is only 14%, requiring a larger dose compared to subcutaneous administration.
- Common adverse effects include flushing and heat at the injection site, neck pain, dizziness, and tingling of the hands.
- Melatonin is primarily used for relieving itching associated with skin disorders such as allergic dermatitis.
5HT1 Receptor
- The 5HT1 receptor has subtypes A, B, and C, each with its unique function.
- In the central nervous system, the 5HT1 receptor affects functions like sleep, appetite, body temperature, and cognition.
- In blood vessels, the 5HT1 receptor triggers vasoconstriction.
Buspirone
- Buspirone acts as an agonist on the 5HT1A receptor.
- Buspirone is primarily an anxiolytic, especially effective for the elderly.
- Buspirone is not addictive.
Clozapine
- Clozapine is effective in treating resistant cases of schizophrenia.
