Choline salicylate is an anti-inflammatory pain reliever agent that is related to aspirin. It is used to decrease swelling and to treat mild-moderate pain. It is used to treat arthritis in both children and adults. This medicine can also be used for fever .
Choline Salicylate is the choline salt of salicylic acid, used as an analgesic, antipyretic and antirheumatic. It relieves mild to moderate pain and reduce fever and inflammation or swelling. Choline salicylate is effective in the treatment of gout, rheumatic fever, rheumatoid arthritis and muscle injuries .
This drug is also a main ingredient in teething gels to relieve pains associated with tooth growth in the infant population . The UK government has regulated its use, due to toxicity in those under 16 years of age. Topical oral salicylate gels are no longer indicated for people younger than 16 years for pain associated with infant teething, orthodontic devices, cold sores, or mouth ulcers .
Tannic acid is a polyphenolic compound. It is a type of the commercially available tannins. It acts as a weak acid. Tannic acid is found in the nutgalls formed by insects on twigs of certain oak trees (Quercus infectoria and other Quercus species). It is removed and used as medicine. In the old days it was used as antidote against different poisons.Nowadays, tannic acid is applied topically for the treatment of cold sores, diaper rash, fever blisters and poison ivy. Tannic acid is also taken by mouth and applied directly for bleeding, chronic diarrhea, dysentery, bloody urine, painful joints, persistent coughs, and cancer.

How Ora G works
Choline salicylate relieves pain by inhibition of prostaglandin synthesis and reduces fever by acting on the hypothalamus heat-regulating center. It also inhibits the generation of impulses through the inhibition of cyclooxygenase enzyme (COX) , .
Cyclooxygenase is involved in the production of prostaglandins, in response to injury and after various other stimuli. The prostaglandins promote pain, swelling, and inflammation. The choline salicylate decreases inflammation and pain by reducing the production of these prostaglandins in the area of the mouth it is applied to .
Pharmaceutical grade tannic acid is generally considered to be pentadigalloylglucose. It has an astringent effect. When used internally, it dehydrates tissues when cause reduction in secretions. Externally, it works through formation of protective layer of harder and constricted cells. Tannic acid is thought to exert antiviral and antibacterial effects.
Toxicity
LD50, oral in mouse: 2690mg/kg . Ld50, subcutaneous in mouse: 1gm/kg .
Interferes with thyroid function test .
Gastrointestinal (GI) disorders, fatigue, hypersensitivity reactions, skin eruptions, hemolytic anemia, weakness, dyspnoea; local irritation (rectally); Reye's syndrome.
Potentially Fatal: Paroxysmal bronchospasm; hepatotoxicity; renal impairment/failure; thrombocytopenia, iron-deficiency anemia, occult bleeding, leukopenia; mild chronic salicylate intoxication .
Salicylate poisoning is normally associated with plasma concentrations >350 mg/L (2.5 mmol/L). Most adult deaths due to salicylate poisoning occur in patients whose serum concentrations of salicylate are over 700 mg/L (5.1 mmol/L). Single doses of less than 100 mg/kg are very unlikely to lead to serious poisoning. Patients should be provided with supportive therapy or treatment for salicylate poisoning as necessary. This may include treatment like activated charcoal, urinary alkalinization and, in severe cases, hemodialysis .
LD50 is 2.26 g/Kg in rats.
Volume of Distribution
0.15 L/kg (salicylate), and widely distributed throughout extracellular water and most tissues
Elimination Route
Onset: 1-2 hr after ingestion
In the oral form, choline salicylate is absorbed across the buccal mucosa. There is a need for caution not to exceed the stated dose and monitor for any signs of suggested salicylism, especially when this drug is used for infants .
In one study, it was found that this drug was more rapidly absorbed than ASA (absorption t1/2 = 0.1 vs 0.36 h) .
After ingestion it has poor bioavailability, due to large size, high affinity to bound to plasma proteins and low lipid solubility. Its main actions are due to local effects.
Half Life
The plasma half-life of salicylic acid is 2-4 hours . Up to 15 – 30 h with larger doses due to saturation of liver metabolism capacity .
Elimination Route
Both metabolites of choline salicylate, and a small amount of intact salicylic acid are excreted, primarily in the urine [L1239].
