An experiment is performed on a laboratory animal to determine the identity of a skeletal muscle relaxant. Drug X causes bronchospasm, hypotension, excessive bronchial and salivary secretions, and mydriasis, in addition to skeletal muscle paralysis. When pretreated with diphenhydramine, the hypotension is attenuated, skeletal muscle paralysis occurs, but bronchodilation and xerostomia are observed. The mydriasis is unaffected. Which of the following is most likely the skeletal muscle relaxant being studied?
A. Atracurium
B. Mivacurium
C. Pancuronium
D. Succinylcholine
E. Tubocurarine

Actually I did not read the question carefully.Since tubocrurine releases histamine and may cause bronchoconstriction, so I quickly put it but in fact it was a Blunnnnnnnnnnnnnnnndddddddddddderrrrrrrrrrrrr.

guys tubocurarine is the correct answer as it causes histamine release and histamine release leads to bronhoconstriction,vasodilation,hypotension,incr bronchial and salivary secretions...right....
