Good morning. I would like to know what concentration drugs are used in hospital practice, e.g. in psychiatric hospitals. Once I was in a psychiatric clinic where I was given the sleeping antidepressant Trittico (trazodone) 150mg for 2 weeks per night. I felt its effects until 5 p.m. the next day, and if I drank coffee in the morning or early afternoon, I felt the coffee stop working after half an hour. I became very silted after trazodone and I felt lethargic and I was discontinued and given a large transparent capsule with white powder (it was still before noon) and when I asked what the capsule / drug was, it was said that it was a drug for concentration. Within half an hour, up to an hour after the drug was administered, I felt a significant improvement in my mental state, i.e. "I woke up from lethargy", I could think briskly and be intellectually brilliant again, that is, I returned to normal. I would like to know what the drug could have been. A friend who is interested in psychiatric drugs told me that it could have been some acetylcholinesterase inhibitor, but I'm not sure if it could have been such a drug, because drugs of this type do not come in transparent capsules, and donepezil is in tablets.
