How are chemicals like Isopropyl Alcohol and Sodium Hydroxide highly toxic on their own, but are safe when in a solution like Gaviscon?

Neither on those are particularly toxic in dilute small amounts. IPA is about as toxic as ethanol, give or take a factor of two. Sodium hydroxide is a strong base, which makes it dangerous when concentrated, but it’s fairly harmless when dilute, or used to neutralize other ingredients. It;s traditionally used to make bagels or pretzels. That yummy brown crust needs a high pH for the reaction to take place in the oven.
