@Natalie Что же вы, Natalie, в глоссарий-то ввели? Это же контекстно-зависимый термин.

Both answers were correct But I considered kapura's answer more helpful.

Alex Marshall May 22, 2011:

Thanks Ivan, But kapura insists "blocker acid" is WRONG (and he flooded me with messages to this end), so your choice and this particular statement, "I would like to explain my choice. Although Alex's answer is correct, and he is the first to answer the question, kapura's answer is more detailed", make even less sense. But I suppose I couldn't care less.

Dear friends, Thank you all for your help. I would like to explain my choice. Although Alex's answer is correct, and he is the first to answer the question, kapura's answer is more detailed. I consider it more helpful.
Unfortunately, I disagree with Natalie who removed the inverted commas (See the change notification below). The original text says "блокирующая кислота" and references provided by kapura explain the reason: it is an informal name for that difficult-to-pronounce-and-spell acid and should be written in inverted commas.
And one more note. "Blocker acid" is not "acid blocker" or "acid reducer".
Nevertheless I want to thank all of you for your help. I hope, we'll co-operate in future.
