“ Furosemide (10-6-10-4 M) reduced the concentration of d-tubocurarine required to achieve 50% twitch tension depression in the indirectly stimulated rat diaphragm.”
“In contrast, in higher doses (1–4 mg/kg) furosemide produced stimulusbound repetitive neural activity, initiated neural activity, increased the force of muscle contraction, enhanced nerve and muscle responses to NaF and dibutyrl cyclic AMP, and antagonized d-tubocurarine and succinylcholine blockades.”
