3Chewable tablets are always [blank_start]very big[blank_end] – >1.5 g. This is deliberate to [blank_start]stop[blank_end] people swallowing the tablets whole, as they must be mechanically [blank_start]disintegrated[blank_end] in the mouth. They [blank_start]do not[blank_end] contain their own disintegrant.
They do contain [blank_start]sorbitol or mannitol[blank_end] as fillers. The drug is not dissolved in the mouth but swallowed and [blank_start]dissolved[blank_end] in the intestine. e.g., antacids.- Avery big

5Effervescent tablets are very [blank_start]big[blank_end] to prevent swallowing. Carbon dioxide is produced by a reaction in water between a [blank_start]carbonate or bicarbonate[blank_end] and a weak acid such as [blank_start]citric or tartaric[blank_end] acid. They contain water soluble [blank_start]lubricant[blank_end] and no [blank_start]binder[blank_end].
