Hyronalin (also spelled hyronalyn or hyronaline) was a drug used to treat radiation poisoning, used during the 23rd and 24th centuries. It had been a standard treatment for radiation poisoning since the late 2100s decade. (TOS episode: "The Deadly Years"; ST website: StarTrek.com)
History and specifics
Hyronalin is an autonomic nervous system stimulant. It is easier to produce and acts more quickly, with better results, than adrenaline. Potential side effects include pulmonary edema, headache, anxiety, and palpitations. A 10 cc dose is standard; an overdose could be fatal. (ST reference: Star Fleet Medical Reference Manual)
A 23rd century Starfleet medical pouch contains 12 hypospray doses each of hyronalin, masiform-D and neural paralyzer. (FASA RPG modules: Trader Captains and Merchant Princes (2nd edition), Spacelanes: The Magazine of Interstellar Trade)
A hyronalin derivative was used by Federation sociological observers on planet NGC 667 due to the degree of naturally occuring radiation on that world. (TOS - Constellations short story: "First, Do No Harm")
In 2267, when hyronalin proved ineffective, Leonard McCoy resorted to using adrenaline to cure a landing party suffering from hyperaging triggered by radiation exposure. (TOS episode: "The Deadly Years")
In 2282, the USS Enterprise was damaged by rogue Mestikan vessels near the pulsar PSR 418-D/1015.3. Captain Spock used a photon torpedo to trigger a radiation burst from the pulsar that disabled the enemy ships. Prior to firing, he asked McCoy to prepare hyronalin doses in case they were needed.

In 2373, The Doctor treated Tom Paris with a mixture of hyronalin and lectrazine to inoculate against radiation exposure while he attempted to collect plasma from a subspace disruption aboard the shuttle Cochrane. (VOY episode: "Real Life")
In 2376, the inhabitants of Europa Nova used hyronalin to treat those suffering from exposure to the theta radiation from the Malon tanker Apsac. They began to run out, although they changed to arithrazine as it better treated the unusual effects of theta radiation better than hyronalin. (DS9 novel: Demons of Air and Darkness)
In October 2376, radiation pulses from a bomb on Trill injured many joined Trills. Symbionts were recovered and kept in hyronalin-saturated, nutrient-rich pools to help preserve their memories. (DS9 - Worlds of Star Trek: Deep Space Nine novel: Trill: Unjoined)
