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.
Bluebirds relish mealworms, which are the larvae of the darkling beetle (Tenebrio molitor Linnaeus, also called yellow mealworm or golden grub). Bluebirds will eat larvae (worms), pupae and beetles (before the shell gets hard), but prefer the worm form.luebirds relish mealworms, which are the larvae of the darkling beetle (Tenebrio molitor Linnaeus, also called yellow mealworm or golden grub).
