Similarly, quiniodochlor linked scenarios of subacute myelooptic neuropathy (SMON)

Various environmental factors affect drug responses. Exposure to insecticides, carcinogens, tobacco smoke and use of charcoal broiled meat are well-known to induce drug metabolism. Sort of diet program and temporal relation between drug ingestion and foods can change drug absorption, e.g.
