[2025-10-02T06:12:34.768608] [PI reasoning] **Answering pharmacology question**

I need to answer a pharmacology question about vasomotor reversal, also known as Dale's phenomenon. When epinephrine raises blood pressure but decreases it after an alpha-blocker, this is due to beta-2 mediated vasodilation. In an animal model, alpha-1 receptors are blocked before stimulating beta-2. So, going through the options: Option A is incorrect; Option B matches since it involves blocking alpha-1 and stimulating beta-2. Options C and D are also incorrect. Therefore, the answer is B. I might consider citing pharmacology textbooks, like Goodman & Gilman, for support.
