Benzocaine, an ester local anaesthetic, blocks the initiation and conduction of nerve impulses by decreasing the neuronal membrane’s permeability to Na ions, which results in inhibition of depolarisation with resultant blockade of conduction.
Benzocaine is indicated for use as a topical anesthetic. It has a duration of action of approximately 10 minutes and a wide therapeutic window. Patients should be counselled regarding the risks of methemoglobinemia.
Interferon alpha 2b (human leukocyte clone hif-sn 206 protein moiety reduced). A type I interferon consisting of 165 amino acid residues with arginine in position 23. This protein is produced by recombinant DNA technology and resembles interferon secreted by leukocytes. It is used extensively as an antiviral or antineoplastic agent.
Upregulates the expression of MHC I proteins, allowing for increased presentation of peptides derived from viral antigens. This enhances the activation of CD8+ T cells that are the precursors for cytotoxic T lymphocytes (CTLs) and makes the macrophage a better target for CTL-mediated killing. Interferon alpha also induce the synthesis of several key antiviral mediators, including 2'-5' oligoadenylate synthetase (2'-5' A synthetase) and protein kinase R.
Taurine, whose chemical name is 2-aminoethanesulfonic acid, is one of the most abundant amino acids in several organs. It plays important role in essential biological processes. This conditional amino acid can be either be manufactured by the body or obtained in the diet mainly by the consumption of fish and meat. The supplements containing taurine were FDA approved by 1984 and they are hypertonic injections composed by cristalline amino acids.
The diet supplements containing taurine are formulated as a well-tolerated nitrogen source for nutritional support. Administration of diet supplements regulates the level of plasma amino acid concentration, nitrogen balance, weight and serum protein concentration to reach normal values, thus improving the nutritional status.

Uses
For the temporary relief of pain due to minor injury or irritation of the mouth and gums like Toothache, Sore gums, Canker sores, Braces, Minor dental procedures, Dentures
Interferon alfa-2b is a form of recombinant human interferon used to treat hepatitis B and C infection, genital warts, hairy cell leukemia, follicular lymphoma, malignant melanoma, and AIDs-related Kaposi's sarcoma.
For the treatment of hairy cell leukemia, malignant melanoma, and AIDS-related Kaposi's sarcoma.
Taurine is an ingredient found in mixture products indicated for nutritional support.
The use of diet supplements containing taurine is indicated for the nutritional support of infants and young pediatric patients requiring total parenteral nutrition via central or peripheral routes. The usage of diet supplements containing taurine prevents nitrogen and weight loss or to treat negative nitrogen balance in pediatric patients where the alimentary tract cannot be done through oral, gastrostomy or jejunostomy administration, there is impaired gastrointestinal absorption or protein requirements are substantially increased.
Генферон is also used to associated treatment for these conditions: Acute Sore Throat Pain, Dental Pain, Gangrene Stomatitis, Gingivitis, Hemorrhoids, Laryngitis, Pharyngitis, Premature Ejaculation, Secondary Bacterial Infection caused by Tonsillectomy, Secondary Bacterial Infection caused by Tooth Extractions, Skin Irritation, Sore Throat, Stomatitis, Sunburn, Teething pain, Tonsillitis, Tooth Pain, Vomiting, Pruritic dermatosis, Ulceration of the mouth, Buccopharyngeal anesthesiaChronic Hepatitis C Virus (HCV) Infection, Hairy Cell Leukemia (HCL), Kaposi’s sarcoma, Melanoma, MalignantTotal parenteral nutrition therapy
How Генферон works
Benzocaine diffuses into nerve cells where it binds to sodium channels, preventing the channels from opening, and blocking the influx of sodium ions. Nerve cells unable to allow sodium into cells cannot depolarize and conduct nerve impulses.
Interferon alpha binds to type I interferon receptors (IFNAR1 and IFNAR2c) which upon dimerization activate two Jak (Janus kinase) tyrosine kinases (Jak1 and Tyk2). These transphosphorylate themselves and phosphorylate the receptors. The phosphorylated INFAR receptors then bind to Stat1 and Stat2 (signal transducers and activators of transcription)which dimerize and activate multiple (~100) immunomodulatory and antiviral proteins. Interferon alpha binds less stably to type I interferon receptors than interferon beta.
The diet supplements containing taurine function by replacing the missing nutriments in the body. Taurine, as a single agent, presents different functions like substrate for formation of bile salts, cell volume regulation, modulation of intracellular calcium, cytoprotection of central nervous system, etc.
Dosage
Генферон dosage
Apply to the affected area up to 4 times daily or as directed by a doctor/dentist. Children under 12 years of age should be supervised during the use of this product. Children under 2 years of age should be consulted to a doctor/dentist prior to the use of this product. An easy application might be done by fixing applicator on the tube’s nozzle. After application, supplied cap should be fixed on top of the applicator.
Side Effects
Side effects are less common. The side effects include allergies, swelling in the mouth or throatetc.
Toxicity
Patients experiencing an overdose may present with local anesthetic systemic toxicity syndrome, decreased cardiovascular function, decreased central nervous system function, cardiac arrest, bradycardia, hypotension, cardiac arrhythmias, syncope, and seizures. Patients should be treated with symptomatic and supportive measures which include airway maintenance, controlling seizures, and hemodynamic stabilization.
There is limited experience with overdosage. Postmarketing surveillance includes reports of patients receiving a single dose as great as 10 times the recommended dose. In general, the primary effects of an overdose are consistent with the effects seen with therapeutic doses of interferon alfa-2b. Hepatic enzyme abnormalities, renal failure, hemorrhage, and myocardial infarction have been reported with single administration overdoses and/or with longer durations of treatment than prescribed. Toxic effects after ingestion of interferon alfa-2b are not expected because interferons are poorly absorbed orally.
The administration of taurine has been correlatefd to significant in the hypothalamus and the modification of neuroendocrine functions. Other than that, taurine administration in regular doses is reported by different articles and institutions to be safe.
Precaution
Patient with asthma, bronchitis, emphysema, heart disease; smokers. Children, Pregnancy and lactation.
Interaction
May antagonise the therapeutic effect of sulfonamides. Anticholinesterases may inhibit the metabolism benzocaine.
Volume of Distribution
The distribution of taurine was studied under the two-compartment model and each one of the compartments gave a range for the volume of distribution of 299-353 ml/kg in compartment 1 and 4608-8374 ml/kg in compartment 2 in mice. Further studies in healthy indivudals gave a volume of distribution that ranged from 19.8 to 40.7 L.
Elimination Route
Absorption is high (greater than 80%) when administered intramuscularly or subcutaneously.
Oral administration of taurine was studied and it reported dose-dependent values of AUC, Cmax and tmax wherein a dose of 1-30 mg/kg ranged from 89-3452 mcg min/L, 2-15.7 mcg min/ml and 15 min respectively. Further studies in healthy individuals gave an AUC, Cmax and tmax in the range of 116-284.5 mg h/L, 59-112.6 mg/L and 1-2.5 h.
Half Life
The elimination half-life following both intramuscular and subcutaneous injections was approximately 2 to 3 hours. The elimination half-life was approximately 2 hours following intravenous injection.
Oral administration of taurine in healthy individuals gave a plasma elimination half-life that ranged from 0.7-1.4 h.
Clearance
The clearance rate of orally administered taurine was reported to be dose-dependent wherein a dose of 1 mg/kg it presents a clearance rate of 11.7 ml min/kg, 10 mg/kg generates a clearance rate of 18.7 ml min/kg and a dose of 30 mg/kg reports a clearance rate of 9.4 ml min/kg. Further studies in healthy individuals generate a clearance rate that ranged from 14 to 34.4 L/h.
Elimination Route
Taurine flows and gets distributed in veins and arteries and reports have observed the presence of a significant released of taurine in portally drained viscera, thus suggesting that the main elimination route of taurine is by the gut. This elimination route may be explained by the enterohepatic cycle of taurine.
