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.
Cook at 350 degrees for 40 mins, then take out and drain any grease. Take any remaining tomato soup/sauce mix and pour it over the top of your meatloaf and let cook another 15 to 20 mins. When cooking meatloaf I do recommend a meat Therm. to test inside temp of your meat loaf, this way keeps you from over-cooking it.
