Ranitidine is a competitive, reversible inhibitor of the action of histamine at the histamine H2-receptors, including receptors on the gastric cells. Ranitidine does not lower serum Ca++ in hypercalcemic states. Ranitidine is not an anticholinergic agent.
1 The Blue Marlins have a diet of: Octopi, squid and pelagic fish such as black fin tuna and frigate mackerel.  They do prefer to hunt alone and during the day, rather than in schools, so it is safe to say they are a rather antisocial species.
Not sure how deep it is in the channel between the Corn Islands but blue marlins are typically caught in blue water aka these beasts and top of the food chain predators spend most of their lives way out at sea. The cool thing about the Corn Islands is that we are way out at sea. Besides these two small land masses, itâs just open blue water for ages. This fish is huge but itâs still not a large marlin, females often average four times the size of the males and often exceed 1200lbs, wow.
