abstract
- Chronic administration of the norepinephrine (NE) reuptake inhibitor nisoxetine reduced the sensitivity of the NE receptor-coupled adenylate cyclase system in rat cortex. This subsensitivity, unlike that caused by desipramine (DMI), was not related to a reduction in specific beta-adrenergic receptor binding. The specific serotonin reuptake inhibitor fluoxetine had no effect on either neurohormonal sensitivity or 3H-dihydroalprenolol binding.
