Cyanide poisoning
Cyanide poisoning: rapid, potentially fatal toxicity from HCN, cyanogen chloride, or cyanide salts that blocks cellular oxygen use via cytochrome c oxidase inhibition; treated with oxygen and antidotes, chiefly hydroxocobalamin and sodium thiosulfate.
Cyanoacrylate injection
Cyanoacrylate injection is an endoscopic treatment in which medical-grade glue is injected into gastric varices to stop bleeding in portal hypertension, achieving hemostasis in about 90% of patients.
Cyanocobalamin
Cyanocobalamin, also called vitamin B12, is the most stable and most common supplemental form of cobalamin, a synthetic cyano-cobalt complex crystallized in 1948 and activated in the body by MMACHC decyanation.
Cyanosis
Cyanosis: bluish skin and mucous membrane discoloration from excess deoxyhemoglobin (over 5 g/dL) or abnormal hemoglobins. Types are central, peripheral, and differential; causes span lung, heart, and hemoglobin disorders.

Cyborg
Cyborg: a cybernetic organism, a human integrally combined with technology. Coined by Clynes and Kline in 1960 for space-flight self-regulation; today covers brain-computer implants, prosthetics, and human augmentation.
Cychlorphine
Cychlorphine, also known as N-propionitrile chlorphine, is a synthetic opioid of the orphine family with no approved medical use, estimated to be about 10 times more potent than fentanyl.
Cyclacillin
Cyclacillin (ciclacillin, Wy-4508, Cyclapen-W) is a discontinued semisynthetic penicillin, a cyclohexylamido analog of penicillanic acid, FDA-approved in 1979, with faster and higher absorption than ampicillin and lower diarrhea rates than amoxicillin.
Cyclandelate
Cyclandelate (Cyclospasmol, CAS 456-59-7) is a mandelic acid ester vasodilator, a direct-acting smooth muscle relaxant once used for claudication, Raynaud's disease, and migraine prophylaxis; discontinued in the US and Canada in 1997 for lack of efficacy.
Cycle ergometry
Cycle ergometry is an exercise testing method in which a patient pedals a stationary bicycle ergometer against controlled resistance, with power output prescribed in watts and cardiopulmonary responses recorded.
Cyclic neutropenia
Cyclic neutropenia, also called cyclic hematopoiesis, is a rare autosomal dominant ELANE-related immunodeficiency with ~21-day oscillations of neutrophil counts to ANC <0.2×10⁹/L, causing recurrent fever, mouth ulcers, and infections, treated with G-CSF.
