'''Cytoprethaline''' is a cellular anti-crystalline drug designed for [[human]]s in [[Cryo chamber|cryo-sleep]], and used in conjunction with [[Bronchial surfactant]]. Within the [[Unified Earth Government]], cytoprethaline is an [[Wikipedia:Prescription drug|Rx-only drug]]; legal only through a medical prescription.{{Ref/Site|Id=waypoint|URL=https://www.halowaypoint.com/en-us/universe/tech/cytoprethaline|Site=Halo Waypoint|Page=Cytoprethaline|D=27|M=10|Y=2015}}
'''Cytoprethaline''' is a pharmaceutical compound used by the [[United Nations Space Command]] (UNSC) to protect human tissue during [[Cryo-sleep]]. The drug prevents cellular damage caused by ice crystal formation during cryogenic stasis, allowing humans to survive long-duration interstellar travel.{{Ref/Novel|Id=TFORCryo|TFoR|Chapter=1}}
Cytoprethaline stabilizes cell membranes and inhibits intracellular ice crystallization during the freezing and thawing processes associated with cryogenic suspension. Without the drug’s protective effects, cryo-sleep is almost always fatal in human subjects.{{Ref/Novel|Id=CPMedical|Oblv|Chapter=12}}
 
The compound is routinely administered prior to entry into cryogenic stasis aboard UNSC spacecraft. Standard procedure calls for the drug to be injected shortly before a subject enters a cryo tube.{{Ref/Reuse|CPMedical}}

Cytoprethaline prevents damage to cell membranes from ice crystal formation. It is usually injected, recommended by a doctor, but usually by a [[medic]] or a pre-measured self-injector.{{Ref/Book|Id=Enc09|Enc09|Page=216}}{{Ref/Book|Id=Enc11|Enc11|Page=226}} The injection of cytoprethaline is routed into the [[Wikipedia:Subcutaneous tissue|subcutaneous tissue]].{{Ref/Reuse|waypoint}} Cytoprethaline was developed around the same time that [[cryonics]] became commonplace due to interstellar travel, to account for the dangers of low temperatures in cryo-sleep. Cryo-sleep is almost always fatal without the use of cytoprethaline.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}}
 
Cytoprethaline is used primarily to prevent damage to cell membranes caused by the formation of ice crystals during cryogenic suspension.{{Ref/Reuse|CPMedical}}
 
The drug is typically administered through a subcutaneous injection prior to entering cryo-sleep. While medical supervision by a physician is recommended, it is commonly administered by a UNSC medic or through a premeasured self-injector system used during large-scale cryogenic embarkation procedures.{{Ref/Reuse|CPMedical}}
 
Cytoprethaline was developed alongside the widespread adoption of cryogenic stasis as a standard method of transporting personnel during interstellar travel. Its use became routine as humanity expanded beyond the Sol system and long-duration slipspace voyages became common.{{Ref/Reuse|CPMedical}}

==Allergic reactions==
However, 1 in 50,000 people exhibit an allergic reaction to this drug; those that do are disqualified from [[United Nations Space Command|UNSC]] service or discharged if discovered after entering training, but can still serve in [[civilian]] roles attached to the UNSC.{{Ref/Reuse|Enc09}}{{Ref/Reuse|Enc11}} [[Thomas Lasky]] is one of the few people to be diagnosed with this allergy, which was to be grounds for his discharge from [[Corbulo Academy of Military Science]]; however, the school [[Battle of Circinius IV|was attacked]] by the [[Covenant]] before Lasky was shipped out.{{Ref/Reuse|FUD3}}


An allergic reaction to cytoprethaline results in blistering, peeling, or red skin rashes. Itching or hives, as well as swelling in the face, hands, or feet are other common allergic reactions. Swelling, or at least tingling, can also occur in throat or mouth. Trouble breathing, shortness of breath, chest tightness, cold sweat, and bluish-colored skin are common, severe results from a cytoprethaline allergic reaction. Sudden or severe headaches, or dizziness or problems with speech or with walking are other reactions.{{Ref/Reuse|waypoint}}
Although Cytoprethaline is considered safe for the overwhelming majority of the population, approximately '''1 in 50,000 individuals''' exhibits a severe allergic reaction to the drug.{{Ref/Reuse|CPMedical}}
 
Individuals diagnosed with a Cytoprethaline allergy are disqualified from active UNSC service, as cryogenic stasis is required for most deep-space deployments. However, such individuals may still serve in civilian or auxiliary roles attached to the UNSC that do not require cryo-sleep.{{Ref/Reuse|CPMedical}}
 
One known case of Cytoprethaline allergy is [[Thomas Lasky]], who was diagnosed while attending [[Corbulo Academy of Military Science]]. His condition would normally have resulted in his discharge from UNSC service, though the academy was attacked by the [[Covenant]] before the process could be completed.{{Ref/Film|Id=FUDLasky|FuD}}
