About H2 blockers. H2 blockers â also known as histamine 2 receptor antagonists â are medications that decrease the amount of acid the stomach produces. These drugs are used to treat various gastrointestinal disorders.2 blockers work by preventing the action of histamine, a substance released by the human immune system during allergic reactions. Histamine normally interacts with gastric H2 receptors to produce stomach acid. The H2 blockers inhibit this response and help reduce gastric acid output.
How long does it take to cook a 2.5-pound meatloaf? Recipes vary, but a meatloaf is generally baked for between 1 to 1 1/2 hours in a 350 to 400 degree oven. The type of meat and fillers used affect the cooking time.
Place your meatloaf in the roasting pan and shape into a loaf. Bake at 350 degrees for 1 hour to 1 1/2 hours. Cooking the meatloaf this way ensures that all of the heat from the oven can get to all sides of the meatloaf and not just the top like in a loaf pan.eport Abuse. For a 2 pound meatloaf....I'd set the oven to 350 degrees and place the meatloaf on a heavy baking pan. (like the bottom of the broiler pan). It's heavy so it browns well. Spray or rub with olive oil..and place the meatloaf there sprinkle with flour all over and pat it on.
