<span>Its called Doxycycline-induced esophageal ulcer. Its not common. I have been taking Doxy for many years for acne without any complication. Then one night I took a single pill, drank half a glass of water, and went to bed. I woke up with mild heartburn. A few days later, I was in immense pain. I felt burning up and down my whole chest. I was bloated, gassy, and couldnt burp. The pain was so severe, it caused me have a migrane. The pill dissolved in my esophagus, and caused an ulcer. It was my fault for not drinking a full glass of water, and going straight to bed. Im in treatment now, and am scheduled for an esophagogastroduodenoscopy. Im feeling a little better already after the first day of treatment, but ulcers take 4-8 weeks to heal.</span>

When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.
So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.
Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.
So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.
