Hyperthyroidism is linked to several muscle disorders, including thyrotoxic myopathy, myasthenia gravis, and periodic paralysis. Thyrotoxic periodic paralysis (TPP) is a rare and potentially life-threatening neuromuscular condition that predominantly affects Asian males and is characterized by muscle weakness, hypokalemia, and thyrotoxicosis. Treatment involves potassium supplementation, and beta-blockers.

Background: Emodepside is an anthelmintic used in veterinary medicine that is currently under investigation in human clinical trials for the treatment of soil-transmitted helminths and possibly Onchocerca volvulus. Emodepside targets the calcium-activated voltage-gated potassium slowpoke 1 (SLO-1) channels of presynaptic nerves of pharynx and body wall muscle cells of nematodes leading to paralysis, reduced locomotion and egg laying, starvation, and death. Emodepside also has activity against Drosophila melanogaster SLO-1 channels.
