I'm revisiting this because it hasn't been sitting well with me and I should have touched on this before. Coatings are generally a time release/sustain release mechanism, which is fine and good in normal usage. But you're trying to ctb. Crushing overrides that mechanism which is essential for that. The source Kera kindly shared seems to weirdly discount that important facet in the context of what you are trying to accomplish. Coating permits the medication to bypass the stomach so it is gradually released as it makes its way through the intestine, yes. This does not necessarily mean the active ingredient would be "destroyed" in the stomach. It's just not ideal for normal usage/intended time release. You want it all at once. It's possible even that source has misinterpreted this, they're not infallible. So for that reason, unless it divulges detail about specific medications/key ingredients, e.g. the amitriptyline we're talking here, that are in fact compromised and destroyed by stomach acid before proper absorption, I'm going to say crush away, which eliminates bollus risk, is more efficient and less tedious than a big bowl of applesauce (wam and bam), and defeats time release for ctb purpose. Crush + water is still the play here, imho.
Thank you very much for your detailed answer.
I´m asking Google to trying to figure out if ami gets destroyed by stomach acid. What I found out was that Ami is actually available as a normal tablet.
That means the active substance is apparently NOT destroyed by the stomach acid. Normal tablets dissolve immediately in the stomach.
So we should also be able to crush the dragees and thus only cancel the time delay and not the effect. Or am I thinking wrong?
John Ryder says "Coatings are generally a time-delayed/sustained release mechanism"
Yes, if it is a gastric-resistant dragee.
For a sustained release, there is the sustained-release tablet.
The very stable coating is primarily intended to protect against environmental influences such as water or oxygen. This protects active ingredients that are neither water nor oxygen stable.
Galaxie76 says: "Normal tablets dissolve immediately in the stomach."
Most tablets only work when the drug – i.e. the active ingredient in the tablet – is released in the intestine.
For example, you take a pill with plenty of water and it goes through your mouth through the esophagus into the stomach. From there it goes into the intestine. The intestine is the main absorption site for active ingredients. Your body then sends the substances through the body via the blood.
I have a small overview here:
As with the film-coated tablet, the coated tablet has several functions:
The taste of the drug is pleasant.
The medicine smells good.
The smooth surface makes it easy to swallow the tablet.
The coating protects the active pharmaceutical ingredient from external influences, such as reactions with atmospheric oxygen, water or wear and tear during storage.
The shell can also be constructed in such a way that the dragee is resistant to gastric juice . An active ingredient that is only supposed to develop its effect in the small intestine is thus protected from undesirable decomposition by gastric acid. The tablet coating then only dissolves in the intestine.
Coloring the medicine with food coloring makes it easier to distinguish it from other medicines and thus increases medicine safety.
Some active pharmaceutical ingredients processed in medicines are very sensitive to acids. When they come into contact with stomach acid, these substances begin to decompose. This is not desirable for all means. The coat of the dragee coating is z. B. from shellac and ensures that the drug passes through the stomach and only unfolds its effect in the intestine.
Extended-Release Tablets
Sustained-release tablets are intended to release their active ingredient with a time delay as they migrate through the intestine . They are appropriate when a constant level of active ingredient is desired. There are several possibilities for that. Among other things, the manufacturers use indigestible carriers from whose pores the active ingredient only gradually escapes. The carrier substance is then excreted apparently unchanged, which can confuse uninformed patients. "The carrier can also be very hard, so don't bite the prolonged-release tablets". Time and time again, patients would break a tooth when trying to chew
Conclusion: With film-coated tablets, I no longer see a problem in crushing them because of the thin film layer.
I have a bitter aftertaste when it comes to dragee.
It's a pity that you can't ask either Amor or emgrl. But I suspect that they had Ami as a pill.
