Studies on the toxic effects of muscle relaxants are difficult to design because of the need for mechanical ventilation and, consequently, concomitant administration of anaesthetic drugs which may influence the results. The following overview shows that muscle relaxants are weak toxic agents with regard to their teratogenicity, carcinogenicity and cytotoxic effects (including tissue- and organ-damaging effects). ⋯ Muscle relaxants and their metabolites may interact with muscarinic and nicotinic receptors in other organs and the ganglionic system, for example in the cardiovascular system. Direct stimulation of mast cells, with consequent release of histamine, after administration of muscle relaxants may clinically impose as toxic reactions.

Review Comparative StudyAnaphylaxis to muscle relaxants: rational for skin tests.
IgE-dependent allergy to muscle relaxants (MR) has an estimated prevalence of 1 out of 6500 General Anesthesias (GA). 62% of anaphylaxis during surgery are due to MR anaphylaxis. All the molecules are divalent, carrying two NH4+ epitopes (quaternary ammonium ions), either structurally or after rapid in vivo protonization (vecuronium). The excellent overall performance of skin test makes them the golden standard for the diagnosis of anaphylactoid reactions. ⋯ Both types of tests can be used for the diagnosis. IDT have to be carried out for the search of the cross sensitization. 84% of patients do have cross sensitization to MRs but only 16% react to all MRs. The further use of MRs selected by negative IDTs has been proved to be safe.
