Cholinergic systems may also be involved in depression since many antidepressants have strong anti-cholinergic activity.

Alternatively, a drug could be metabolized faster than expected into a toxic compound. The mechanisms involved in enzyme induction are unclear but somehow DNA sequences are affected so that production of the relevant enzyme is increased.

Inhibition of enzyme systems may cause adverse reactions due to higher than expected drug concentrations. The effects of inhibition can appear as soon as the inhibiting drug reaches a high enough concentration to compete with another drug for the same enzymes.
