Compositions, and methods of use thereof, are provided for the prevention or treatment of side effects associated with the use of drugs that act as 5HT2 / 5HT3 serotonin receptor antagonists and alpha-2 adrenergic receptor antagonists (5HT2 / 5HT3 antagonist / alpha-2 antagonist). The method involves using dopamine-releasing compounds, such as amantadine, anticonvulsants, such as zonisamide, or dopamine / norepinephrine reuptake inhibitors, such as bupropion, in combination with 5HT2 / 5HT3 antagonist / alpha-2 antagonists, such as mirtazapine, to reduce the excessive daytime drowsiness and / or weight gain associated with 5HT2 / 5HT3 antagonist / alpha-2 antagonist use for the treatment of disorders, such as, depression, schizophrenia, anxiety disorders, sleep-related breathing disorders, insomnia, migraine headache, chronic tension-type headache, hot flashes, lower back pain, neuropathic pain and functional somatic syndromes. Formulations of dopamine-releasing compounds or anticonvulsants with 5HT2 / 5HT3 antagonist / alpha-2 antagonists are provided. In particular embodiments, combination therapy with mirtazapine and zonisamide provides relief from chronic low back pain, while reducing or avoiding side effects associated with monotherapy with mirtazapine or zonisamide.

The present study demonstrates that brimonidine tartrate, an alpha-2 adrenergic receptor agonist, can prevent photoreceptor cell degeneration and the associated Muller cell degenerative signs in an in vitro model of retinal degeneration and retinal detachment (separation of the neuroretina from the retinal pigment epithelium). Similar to control conditions, brimonidine allowed for the formation of highly structured photoreceptor outer segments, prevented the expression of stress markers in Müller cells and preserved the expression patterns of Muller cell markers of proper cell-cell contact and differentiation. Ultrastructural studies also indicated that brimonidine favored the formation of cell-cell junctions between photoreceptor cells and Müller cells, indicating that this phenomenon is associated with the exertion of the neuroprotective effect. The results suggest that brimonidine compounds may be utilized as an effective therapeutic agent for early and late onset retinal degenerations caused by defects in photoreceptor cells, Müller cells or both, and as an adjuvant to therapeutic success in retinal detachment surgery or macular translocation surgery for age-related macular degeneration.
