| Protein Function |
Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor binds epinephrine and norepinephrine with approximately equal affinity. Mediates Ras activation through G(s)-alpha- and cAMP-mediated signaling. Involved in the regulation of sleep/wake behaviors (PubMed:31473062).

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Caution and close monitoring for altered efficacy and safety are recommended if patients receive nefazodone with agents that can produce significant hypotension such as antihypertensive agents or vasodilators. Patients should be made aware of the possible side effects (e.g., dizziness, lightheadedness, orthostasis) and be cautioned about driving, operating machinery, or performing other hazardous tasks. | ||||||||
