Many types of substances are known to interact with amphetamine, resulting in altered drug action or metabolism of amphetamine, the interacting substance, or both.[8][91] Inhibitors of the enzymes that metabolize amphetamine (i.e., CYP2D6 and flavin containing monooxygenase) will prolong its elimination half-life.[5][91] Amphetamine also interacts with MAOIs, particularly monoamine oxidase A inhibitors, since both MAOIs and amphetamine increase plasma catecholamines; therefore, concurrent use of both is dangerous.[91] Amphetamine will modulate the activity of most psychoactive drugs. In particular, amphetamine may decrease the effects of sedatives and depressants and increase the effects of stimulants and antidepressants.[91] Amphetamine may also decrease the effects of antihypertensives and antipsychotics due to its effects on blood pressure and dopamine respectively.[91] There is no significant effect on consuming amphetamine with food in general, but the pH of gastrointestinal content and urine affects the absorption and excretion of amphetamine, respectively.[91] Acidic substances reduce the absorption of amphetamine and increase urinary excretion, and alkaline substances do the opposite.[91] Due to the effect pH has on absorption, amphetamine also interacts with gastric acid reducers such as proton pump inhibitors and H2 antihistamines, which increase gastrointestinal pH.[91]

Brukte selv denne siden da jeg var usikker på diverse kombinasjoner. Skal ikke fortelle hva den vet og ikke vet om Metamina, men du kan sjekke den ut.
