How Anabel Ct works

Although not entirely elucidated, the bactericidal action of benzalkonium chloride is believed to be due to the disruption of intermolecular interactions. Such disruption can cause the dissociation of cellular membrane lipid bilayers of bacteria, resulting in compromised cellular permeability control and the leakage of important cellular contents. Additionally, other important molecular complexes like enzymes which control the maintenance of a great range of respiratory and metabolic cellular activities, are also susceptible to such deactivation. Consequently, a variety of critical intermolecular interactions and tertiary structures in very highly specific biochemical systems that allow bacterial agents to function normally can be readily disrupted or deactivated by cationic surfactants like benzalkonium chloride. .

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 .

Side Effects

Repeated application may cause hypersensitivity reactions. May cause nausea and vomiting if ingested.

Toxicity

An oral dose of 100-400 mg/kg or a parenteral dose of 5-15 mg/kg is believed to be fatal in humans .

A potential concern for larger concentrations of benzalkonium chloride to possibly cause corneal damage when implemented as an excipient ingredient in aqueous eye products is an issue that should be discussed between potential patents and their health care providers . Since decreased regular blinking and tear generation in patients experiencing dry eyes due to any number of eye conditions can result in reduced dilution of applied eye drops containing the benzalkonium chloride preservative , alternative options including benzalkonium chloride-free products should be considered.

Additionally, benzalkonium chloride has been reported to cause punctate keratopathy and/or toxic ulcerative keratopathy. In addition, benzalkonium chloride may cause eye irritation and is known to discolour soft contact lenses . There may also be the possibility of benzalkonium chloride containing eye drops to cause some stinging and pain .

There is the possibility of ototoxicity occurring when benzalkonium chloride containing ear drops are applied to the ear .

Benzalkonium chloride used as a preservative in nebulised solutions of anti-asthma drugs has been reported to cause dose-related bronchoconstriction especially in asthmatic patients and has been associated with the precipitation of respiratory arrest .

Despite the fairly widespread cutaneous use of benzalkonium chloride, only limited human evidence of sensitization in relatively small populations of individuals have been reported . Nevertheless, the main adverse effect for topical formulations of benzalkonium chloride is usually the warning 'may cause local irritation' .

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 .

Interaction

Disinfectants containing quaternary ammonium salts should not be used for skin preparation before injections of viscoelastic solutions. Hyaluronic acid will precipitate in the presence of these salts.

Volume of Distribution

When applied as a topical antibacterial, antiseptic, disinfectant, or sanitizer it is believed that molecules of benzalkonium chloride are poorly absorbed (perhaps due to their large, positively charged nature ), especially considering expectations for such topical applications to keep their biocidal agents available for action at the topical level and to not be absorbed significantly beyond it.

When benzalkonium chloride is implemented as an excipient preservative ingredient in various eye, nose, and ear aqueous products, such products will always have other active pharmacological agents whose volume of distribution will be of greater importance. In these cases the excipients will only ever be present at the minimal levels necessary to maintain the integrity of the product substance.

Moreover, Benzalkonium chloride is currently listed as a Category III ingredient by the United States Food and Drug Administration . Ingredients are listed in the FDA Category III when the data available about them are insufficient to classify as safe and effective, requiring further testing to determine more formal details about elements like human pharmacokinetic studies, and studies on the ingredients' absorption, distribution, metabolism, and excretion.

0.15 L/kg (salicylate), and widely distributed throughout extracellular water and most tissues

Elimination Route

Percutaneous absorption is considered to be insignificant .

In one study, benzalkonium chloride absorption was evaluated in women using tampons containing the agent. Venous blood samples were drawn 15 minutes before the tampon application and then again at 15 min, 1 h, 3 h, and 24 h after application. Benzalkonium chloride was not detected in any of the blood samples at any time tested.

Similarly, in another study, benzalkonium chloride absorption was tested in women using tampons containing the agent. Venous blood and breast milk samples were taken 15 minutes before application and 3 h and 24 h after tampon administration. Benzalkonium chloride was not found in any of the subjects' samples. .

Moreover, in a study where benzalkonium chloride solution was placed on the corneal surface of rabbit subjects, at various intervals after administration, the rabbits' eyes would be washed with 1 mL saline and the following tissues and fluids were removed: bulbar and palpebral conjunctiva, aqueous humour, corneal epithelium, endothelium and stroma, iris-ciliary body, lens, vitreous, retina, and choroid. Plasma samples were obtained with direct cardiac punctures. After administration of one drop, benzalkonium chloride was found in the corneal epithelium, endothelium, and stroma, and in the bulbar and palpebral conjunctivae. Benzalkonium chloride loss from ocular tissues was such that about one-third to two thirds of its concentration (depending on the tissue) at 30 min remained after 24 hr; measurable values existed for as long as 120 hr. The administration of multiple drops led to continued accumulation of benzalkonium chloride. .

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) .

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

Administered benzalkonium chloride is likely eliminated largely in faeces, similar to other quaternary ammonium compounds .

Both metabolites of choline salicylate, and a small amount of intact salicylic acid are excreted, primarily in the urine [L1239].

Contraindication

Incompatible with soaps and other anionic surfactants, citrates, iodides, nitrates, permanganates, salicylates, silver salts, tartrates, and zinc oxide and sulfate.

Storage Condition
