BIBN 99 is an antagonist of mACh receptors. Specifically, it is selective for the M2 type.^[1]

Effects

During research, it was observed that BIBN 99 was able to diminish the cognitive deficits caused by injury.^[2] Another also came to the conclusion that the compound could provide cognitive improvements.^[3] The cognitive effects could possibly be caused by the increased release of acetylcholine, a neurotransmitter.^[4]
