Each ml mouthwash contains 1.5 mg Benzydamine Hydrochloride (w/v)Benzydamine Hydrochloride mouthwash is a Non-Steroidal Anti-Inflammatory Drug (NSAID) with analgesic and local anesthetic properties. The clinical pharmacology of Benzydamine mouthwash is well known. Benzydamine is poorly absorbed in the blood, thereby limiting systemic exposure to the drug when applied topically but ensures high concentration at the site of injury in mouth or throat. Therefore, it provides excellent oropharyngeal pain relief with minimal side effects. Although Benzydamine is a Non-Steroidal Anti-Inflammatory agent, it possesses a different mechanism of action that distinguishes it from conventional NSAIDs. Benzydamine mouthwash shows analgesic & anti-inflammatory action by inhibiting pro-inflammatory cytokines & reducing vascular permeability. Moreover, Benzydamine mouthwash shows local anesthetic property which provides an immediate effect on pain.

Benzydamine is a non-steroidal anti-inflammatory drug (NSAID) designed to elicit local anesthetic and analgesic effects mainly for the mouth and throat. It specifically acts on the local mechanisms of inflammation such as pain, oedema, or granuloma. Typically applied topically, the drug demonstrates anti-inflammatory activity reducing oedema as well as exudate and granuloma formation. Moreover, benzydamine exhibits analgesic properties and local anaesthetic activity if pain is caused by an inflammatory condition. Benzydamine can be absorbed into the oral mucosa and intact skin. Once absorbed in the local area of pain or inflammation, benzydamine binds selectively to local inflamed tissues, usually allowing it to act with few adverse systemic effects. On average a period of 2 to 4 hours is necessary for the substance to reach peak plasma concentration.

Benzydamine can be synthesized with the reaction of the N-benzyl derivative from methyl anthranilate with nitrous acid to give N-nitoso derivative. This is next reduced by sodium thiosulfate to give transient hydrazine. This hydrazine can then undergo spontaneous internal hydrazide formation. Treating this resultant enolate with 3-chloro-1-dimethylamkino propane ultimately yields benzydamine.

Although the precise mechanism of action of Capsaicin is not fully understood, current evidence suggests that Capsaicin exerts an analgesic effect by depleting and preventing reaccumulation of Substance P in peripheral sensory neurons. Substance P is thought to be the principal chemomediator of pain impulses from the periphery to the central nervous system.

Capsaicin is a TRPV1 receptor agonist. TRPV1 is a trans-membrane receptor-ion channel complex activated by temperatures higher than 43 degrees Celsius, pH lower than 6, and endogenous lipids. When activated by a combination of these factors, the channel can transiently open and initiate depolarization due to the influx of calcium and sodium ions. Because TRPV1 is commonly expressed in A-delta and mostly C fibers, depolarization results in action potentials which send impulses to the brain and spinal cord. These impulses result in capsaicin effects of warming, tingling, itching, stinging, or burning. Capsaicin also causes more persistent activation of these receptors compared to the environmental agonists, resulting in a loss of response to many sensory stimuli, described as "defunctionalization". Capsaicin is associated with many enzymatic, cytoskeletal, and osmotic changes, as well as disruption of mitochondrial respiration, impairing nociceptor function for extended periods of time.

How Tantum C works

Despite being categorized as a non-steroidal anti-inflammatory drug (NSAID), benzydamine demonstrates various mechanisms of action that differ from those of traditional aspirin-like NSAIDs. In particular, benzydamine predominantly acts by inhibiting the synthesis of pro inflammatory cytokines like tumour necrosis factor-alpha (TNF-α) and interleukin-1β (IL-1β) without largely affecting other pro inflammatory cytokines (ie. such as IL-6 and IL-8) or anti-inflammatory cytokines (ie. like IL-10 or IL-1 receptor antagonist).

Moreover, benzydamine is largely a weak inhibitor of prostaglandin synthesis as it has been shown to effectively inhibit cyclooxygenase (COX) and lipoxygenase enzyme activity only at concentrations of 1mM or greater. Considering most contemporary usages of benzydamine are topical applications that are generally not well absorbed through the skin and/or non-specialized mucosae, benzydamine does not often achieve the kind of absorption or blood concentrations necessary to cause any extraneous distant systemic effects or COX inhibition, allowing it to localize its action.

Additionally, it is also hypothesized that benzydamine is capable of inhibiting the oxidative burst of neutrophils and membrane stabilization. These actions are exhibited by the substance’s ability to inhibit the release of granules from neutrophils and to stabilize lysosomes.

Furthermore, benzydamine is capable of a local anaesthetic effect that may be related to its capability for inhibiting the release of inflammatory mediators like substance P and calcitonin gene related peptide from sensory nerve endings. Since substance P is capable of causing the release of histamine from mast cells, benzydamine’s prevention of substance P release further contributes to an anti-inflammatory effect.

Benzydamine also demonstrates a non-specific antibacterial activity against various bacterial strains that are resistant to broad-spectrum antibiotics such as ampicillin, chloramphenicol, and tetracycline at concentrations of about 3 mmol/L. Combinatorial use of benzydamine and other antibiotics like tetracycline and chloramphenicol are also synergistic against antibiotic resistant strains of Staphylococcus aureus and Pseudomonas aeruginosa.

Capsaicin has been shown to reduce the amount of substance P associated with inflammation - however this is not believed to be its main mechanism in the relief of pain . Capsaicin's mechanism of action is attributed to "defunctionalization" of nociceptor fibers by inducing a topical hypersensitivity reaction on the skin. This alteration in pain mechanisms is due to many of the following: temporary loss of membrane potential, inability to transport neurotrophic factors leading to altered phenotype, and reversible retraction of epidermal and dermal nerve fiber terminals.

Dosage

Tantum C dosage

15 ml of Benzydamine mouthwash should be rinsed or gargled every 1.5-3 hours or as required, for 20-30 seconds. If stinging occurs, it can be diluted with an equal volume of water.

18 years of age and older:Apply a thin film of Capsaicin cream to affected area 3 to 4 times daily. A burning sensation may occur upon application, but generally disappears with regular use. Application schedules of 3 to 4 times a day for 2 weeks provides optimum pain relief.

Side Effects

Benzydamine Hydrochloride mouthwash can cause side effects, although not everybody gets them. Side effects are generally minor.

Severe allergic reaction which may include a red and lumpy skin rash, difficulty breathing, swelling of face, mouth, lips or eyelids, unexplained high temperature (fever) and feeling faint. If the swelling affects throat and makes breathing difficult and swallowing difficult, patients should be hospitalized
Itchy rash, sometimes with pale, raised areas of skin with red edges (urticaria).
A feeling of numbness in mouth.
A stinging feeling in mouth- the mouthwash may be diluted with water if you experience stinging. This should help to reduce the stinging effect.

Capsaicin may cause transient burning on application. This burning is observed more frequently when the application schedules are more than 3-4 times daily. The burning can be enhanced if too much cream is used and if it is applied just before or after a bath or shower.

Toxicity

A possible adverse reaction associated with the use of the mouthwash or oromucosal spray formulations of benzymadine is potential numbness and/or stinging in the mouth and/or throat .

Some possible adverse reactions that tend to be associated more with topical cream formulations of benzymadine include increased sensitivity to sunlight, and localized itching, skin rash, redness, or swelling .

The prescribing information for all formulations of benzymadine however, warn against the possibility of severe allergic reaction (anaphylaxis) associated with swelling of the throat and mouth, difficulty in swallowing, speaking, and breathing, or wheezing .

As benzydamine is a non-steroidal anti-inflammatory drug (NSAID), it is necessary to determine if a patient is allergic to NSAIDs before considering its use .

Intoxication is expected as a consequence of accidental ingestion of large quantities of benzydamine (over 300 mg ingestion). Other symptoms associated with overdose of ingested benzydamine include gastrointestinal and central nervous system symptoms like nausea, vomiting, abdominal pain, oesophageal irritation, dizziness, hallucinations, agitation, anxiety, and irritability .

The official prescribing information for benzydamine generally suggest that benzydamine mouthwashes and sprays should not be used in pregnancy . Similarly, the official prescribing information for benzydamine also generally suggest that benzydamine mouthwashes and sprays should not be used during lactation unless considered essential by a physician .

The prescribing information for topical cream formulations of benzydamine note that benzydamine cream should not be used in pregnancy or lactation unless considered necessary by the physician .

Overall, non-clinical data reveal no special hazards for humans based on conventional studies of safety pharmacology, repeated toxicity, genotoxicity, cardiogenic potential, and toxicity to reproduction . Additionally, there is no evidence of teratogenic effects in animal studies .

Acute oral LD50 and dermal LD50 in mouse are 47.2 mg/kg and >512 mg/kg, respectively . Capsaicin is shown to be mutagenic for bacteria and yeast .

Capsaicin can cause serious irritation, conjunctivitis and lacrimation via contact with eyes. It induces a burning sensation and pain in case of contact with eyes and skin. As it is also irritating to the respiratory system, it causes lung irritation and coughing as well as bronchoconstriction. Other respiratory effects include laryngospasm, swelling of the larynx and lungs, chemical pneumonitis,respiratory arrest and central nervous system effects such as convulsions and excitement . In case of ingestion, gastrointestinal tract irritation may be observed along with a sensation of warmth or painful burning . Symptoms of systemic toxicity include disorientation, fear, loss of body motor control including diminished hand-eye coordination, hyperventilation, tachycardia, and pulmonary oedema . Careful early decontamination is recommended and medical intervention should be initiated for any life-threatening symptoms. In case of contact, individual must be removed from the source of exposure and the contacted skin and mucous membranes should be thoroughly washed with copious amounts of water .

Precaution

Capsaicin cream should not be applied to broken or irritated skin. Applied area should not be tightly bandaged. Do not get on mucous membranes and into eyes or on contact lenses. If this occurs, rinse the affected area thoroughly with water. Do not apply the cream on the heat treated area as this may increase the burning sensation. In case of accidental ingestion, seek physician advice immediately.

Volume of Distribution

The volume of distribution of benzydamine is 10 L .

Elimination Route

Oral doses of benzydamine are well absorbed and plasma drug concentrations reach a peak fairly rapidly and then decline with a half-life of approximately 13 hours. When applied topically, although the local drug concentrations are relatively large, the systemic absorption of topically applied benzydamine is relatively low compared to oral doses. This low topical absorption contributes to a decreased potential for any systemic drug side-effects when benzydamine is administered in this way.

Oral: Following oral administration, capsaicin may be absorbed by a nonactive process from the stomach and whole intestine with an extent of absorption ranging between 50 and 90%, depending on the animal . The peak blood concentration can be reached within 1 hour following administration . Capsaicin may undergo minor metabolism in the small intestine epithelial cells post-absorption from the stomach into the small intestines. While oral pharmacokinetics information in humans is limited, ingestion of equipotent dose of 26.6 mg of pure capsaicin, capsaicin was detected in the plasma after 10 minutes and the peak plasma concentration of 2.47 ± 0.13 ng/ml was reached at 47.1 ± 2.0 minutes .

Systemic: Following intravenous or subcutaneous administration in animals, the concentrations in the brain and spinal cord were approximately 5-fold higher than that in blood and the concentration in the liver was approximately 3-fold higher than that in blood .

Topical: Topical capsaicin in humans is rapidly and well absorbed through the skin, however systemic absorption following topical or transdermal administration is unlikely . For patients receiving the topical patch containing 179 mg of capsaicin, a population analysis was performed and plasma concentrations of capsaicin were fitted using a one-compartment model with first-order absorption and linear elimination. The mean peak plasma concentration was 1.86 ng/mL but the maximum value observed in any patient was 17.8 ng/mL .

Half Life

Approximately 13 h after oral administration , with a terminal half life of about 7.7 h .

Following oral ingestion of equipotent dose of 26.6 mg of pure capsaicin, the half life was approximately 24.9 ± 5.0 min . Following topical application of 3% solution of capsaicin, the half-life of capsaicin was approximately 24 h . The mean population elimination half-life was 1.64 h following application of a topical patch containing 179 mg of capsaicin .

Clearance

Benzydamine demonstrateas a systemic clearance of 170 ml/min .

Elimination Route

The relatively high lipid solubility of the weak base benzydamine is thought to be associated with considerable passive resorption within the renal tubule, which suggests that only approximately 5% of benzydamine is excreted unchanged in the urine . At the same time however, other studies have suggested that considerably larger amounts (50-65%) of the drug is excreted unchanged in urine .

While several inactive oxidized metabolites of benzydamine are excreted in urine, the benzydamine N-oxide metabolite can remain in plasma and demonstrate a half-life that is longer than the parent benzydamine compound .

Nevertheless, it is generally believed that excretion occurs mainly through urine and is mostly in the form of inactive metabolites or conjugation products .

It is proposed that capsaicin mainly undergoes renal excretion, as both the unchanged and glucuronide form. A small fraction of unchanged compound is excreted in the feces and urine. In vivo animal studies demonstrates that less than 10 % of an administered dose was found in faces after 48 h .
