Allergy is yet another name for idiosyncrasy. It is actually termed idiosyncrasy when a affected individual's reaction to a medication is distinct from its regular pharmacological influence.
Hormesis is generally discussed by assuming a damaging component from the dose-reaction curve within the low dose conclude. Homeopathy claims a curative reaction from a little dose of a drug of which higher doses bring about signs and symptoms just like those from which the patient is suffering. A dose-dependent reverse drug effect is challenging to describe with present versions. From the proposed design this phenomenon is undoubtedly an intrinsic element.

The simulations clearly show the results of tolerance growth on repeated drug administrations. To the tolerance mechanism to function, it should be triggered once the drug is administered. To the behaviour in the mathematical model it is of no relevance if the triggering takes put orally or by environmental cues and no difference in between different types of triggering was made within the simulations.
