Following topical administration into the nasal mucosa, Beclomethasone Dipropionate produces anti-inflammatory and vasoconstrictor effects. The exact mechanism of these actions remain unknown, but may involve reductions in the following: number of mediator cells (basophil, leukocytes and mast cells) at the epithelial level, number of eosinophils, sensitivity of sensory nerves to mechanical stimuli, secretory response to cholinergic receptor stimulation, and fibroblast activity. Other mechanisms may involve inhibition of capillary dilation and permeability, stabilization of lysosomal membranes and subsequent prevention of release of proteolytic enzymes.

Inflammatory conditions, including asthma, dermatoses, and allergic rhinitis, involve the activation of cascades by inflammatory mediators. Inflammation is a primary defense mechanism and the homeostatic response of the immune system; however, a prolonged inflammatory response in certain disorders may lead to tissue damage, pain, and swelling. Beclomethasone dipropionate works by attenuating the inflammatory responses associated with asthma, allergic rhinitis, nasal polyps, and corticosteroid-responsive dermatoses. It suppresses the actions of inflammatory cells, such as mast cells, eosinophils, basophils, lymphocytes, macrophages, and neutrophils. It also inhibits the release of inflammatory mediators, such as histamine, eicosanoids, leukotrienes, and cytokines. Beclomethasone dipropionate is reported to exhibit potent topical activity while possessing low systemic effects.

Beclomethasone dipropionate is a corticosteroid drug with anti-inflammatory and vasoconstrictive effects used to treat chronic inflammatory processes such as asthma, allergic rhinitis, corticosteroid-responsive dermatoses. When inhaled, it improves lung function, decreases airway hyper-reactivity, and reduces the severity of asthmatic symptoms. Although inhaled corticosteroids, including beclomethasone dipropionate, are reported to mainly act locally in the lungs, systemic effects such as disruption of hypothalamic-pituitary-adrenal (HPA) axis function, bone turnover, osteoporosis, and growth suppression may still be observed with chronic use or high dose administration. There were varying findings from clinical studies examining the effect of beclomethasone dipropionate on growth suppression in pediatric patients. It was shown to suppress the hypothalamo-pituitary-adrenal (HPA) axis in a dose-dependent manner. HPA axis is a central hormonal response system to stress and activation of HPA axis leads to the production of endogenous steroid hormone production. Long-term use of high-dose systemic corticosteroids, including those inhaled, was often associated with signs and symptoms of adrenal insufficiency when exposed to stress conditions, such as trauma, surgery, or infections. As corticosteroids work by suppressing the immune system, there may be an increased risk for developing infections. Cases of Candida albicans infection of the mouth and throat have been reported with inhaled beclomethasone dipropionate therapy.

Ketoconazole interferes with biosynthesis of triglycerides and phopholipids by blocking fungal CYP450, thus altering cell membrane permeability in susceptible fungi. It also inhibits other fungal enzymes resulting in the accumulation of toxic concentrations of hydrogen peroxide.

Ketoconazole, similarly to other azole antifungals, is a fungistatic agent which causes growth arrest in fungal cells thereby preventing growth and spread of the fungus throughout the body.

Neomycin is a broad-spectrum aminoglycoside antibiotic drug that is derived from the metabolic products of Streptomyces fradiae. Neomycin is a complex comprised of three components, neomycin A, B, and C. Neomycin B, also known as framycetin, is the most active component of the complex and neomycin C is the isomer of neomycin B, making these two stereoisomers the active components of neomycin. Neomycin A, or neamine, is a moiety that conjoins two molecules of neomycin B and C together. Neomycin is active against both gram-positive and gram-negative organisms and mediates its pharmacological action by binding to bacterial ribosomes and inhibiting protein synthesis, which is crucial for the survival of bacteria.

Neomycin sulfate is the most common form for pharmaceutical preparations; because the compound is a complex, the amount of neomycin in products is measured in units. Neomycin sulfate as monotherapy is available in an oral solution for adjunct use in the treatment of hepatic coma. It is also used in combination with polymyxin B sulfates and hydrocortisone in otic suspensions for use in the treatment of bacterial infections in the external auditory canal, including infections caused by medical procedures in the ear. Neomycin is also used in combination with polymyxin B sulfates and dexamethasone in ophthalmic preparations for use in the treatment of inflammatory conditions and infections in the eye. Neomycin is also available in over-the-counter topical products to prevent minor skin infections.

Neomycin mediates its bactericidal action by inhibiting bacterial protein synthesis, thereby suppressing the growth and survival of susceptible bacteria. Following oral administration, the duration of bactericidal activity of neomycin ranged from 48 to 72 hours. By decreasing colonic bacteria that produce ammonia, neomycin was shown to be effective as an adjunctive therapy in hepatic coma to improve neurologic symptoms.

Treatment of superficial and deep mycoses:

Infections of the skin, hair and nails by dermatophytes and/or yeasts (dermatomycosis, onychomycosis, perionyxis, pityriasis versicolor, chronic mucocutaneous candidiasis etc.) especially when topical treatment is difficult or not very effective, owing to involvement of large skin surfaces or to lesions affecting deeper dermal layers, nails and hairs
Yeast infection of the mouth (oral thrush, perleche) and the gastrointestinal tract
Vaginal candidiasis, especially chronic recurrent cases or cases responding poorly to topcial treatment
Systemic mycotic infections such as systemic candidiasis, paracoccidioidomycosis, histoplasmosis, coccidioidomycosis etc.

Maintenance treatment to prevent recurrence in systemic mycotic infections and in chronic mucocutaneous candidiasis.Prophylactic treatment to prevent mycotic infection in patients with reduced host defenses, e.g., patients with cancer, organ transplant and burns.

Neomycin is an aminoglycoside antibiotic agent used orally and topically to treat a wide variety of infections in the body.

Oral neomycin sulfate is indicated as an adjunctive therapy in hepatic coma (portal-system encephalopathy) by reducing ammonia-forming bacteria in the intestinal tract. It is strongly recommended that oral neomycin is only used in infections that are proven or strongly suspected to be caused by susceptible bacteria to reduce the risk of the development of drug-resistant bacteria.

Neomycin, in combination with polymyxin B sulfates and hydrocortisone in otic suspensions, is used in the treatment of superficial bacterial infections of the external auditory canal caused by organisms susceptible to the antibiotics. This otic formulation is also used in the treatment of infections of mastoidectomy and fenestration cavities caused by organisms susceptible to the antibiotics.

The ophthalmic solution containing neomycin in combination with polymyxin B sulfates and dexamethasone is used to treat steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where bacterial infection or a risk of bacterial infection exists.

How Neo Dermiford works

Beclomethasone dipropionate is a corticosteroid and prodrug that is rapidly activated by hydrolysis to the active monoester, 17 monopropionate (17-BMP), which mediates anti-inflammatory actions. 17-BMP has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor which is approximately 13 times that of dexamethasone and 25 times that of beclomethasone dipropionate. Upon binding of the ligand, the glucocorticoid receptors dimerize and translocate into the nucleus, where they subsequently bind to glucocorticoid response elements (GRE) on glucocorticoid-responsive genes, leading to changes in transcription. There are several proposed mechanisms for the anti-inflammatory action of corticosteroids. Corticosteroids may work by increasing the transcription of genes coding for anti-inflammatory proteins, including lipocortin-1 and interleukin-10. Corticosteroids were also shown to inhibit the expression of multiple genes that encode pro-inflammatory factors, such as cytokines, chemokines, and adhesion molecules, that are activated during the chronic inflammatory process. This is thought to be due to the direct inhibitory interaction between activated glucocorticoid receptors and activated pro-inflammatory transcription factors, such as nuclear factor-kappa B and activator protein-1. Chronic inflammation is often characterized by enhanced expression of these transcription factors that bind to and activate coactivator molecules, which then acetylate core histones to switch on gene transcription to further amplify the inflammatory process. Corticosteroids suppress the multiple inflammatory gene expression by promoting histone deacetylation, resulting in tighter coiling of DNA and reduced access of transcription factors to their binding sites.

Ketoconazole interacts with 14-α-sterol demethylase, a cytochrome P-450 enzyme necessary for the conversion of lanosterol to ergosterol. This results in inhibition of ergosterol synthesis and increased fungal cellular permeability due to reduced amounts of ergosterol present in the fungal cell membrane. This metabolic inhibition also results in accumulation of 14α-methyl-3,6-diol, a toxic metabolite. The increase in membrane fluidity is also thought to produce impairment of membrane-bound enzyme systems as components become less closely packed.

Like other aminoglycoside antibiotic drugs, neomycin inhibits bacterial ribosomes by binding to the 30S ribosomal subunit of susceptible bacteria and disrupting the translational machinery of bacterial protein synthesis. Bacterial translation is normally initiated by the mRNA binding to the 30S ribosomal subunit and subsequent binding with 50S subunit for elongation.

Side Effects

Rare instances of nasal septum perforation have been reported following intranasal administration. As with other nasal sprays, dryness and irritation of the nose and throat, unpleasant taste & smell and epistaxis have been reported rarely. Rare instances of wheezing, cataracts, glaucoma and increased intra-ocular pressure have been reported following the intranasal use of Beclomethasone.

Ketoconazole is very well tolerated. Nausea and itching may occasionally occur. In some patients, an idosyncratic liver reaction may occur (incidence 1 : 10,000).

Toxicity

The oral LD₅₀ in rats is >3750 mg/kg.

The acute toxicity of beclometasone dipropionate is low. The only harmful effect that follows inhalation of large amounts of the drug over a short period of time is suppression of hypothalamic-pituitary-adrenal (HPA) function. Chronic: The excessive use of beclometasone dipropionate over a long period could lead to adrenal suppression.

Symptoms of overdose include acute liver injury, which may include both hepatocellular and cholestatic injury, accompanied by anorexia, fatigue, nausea, and jaundice. In case of overdose, gastric lavage with activated charcoal may be used if within one hour of ketoconazole ingestion otherwise provide supportive care. If the patient shows signs of adrenal insufficiency, administer 100 mg hydrocortisone once together with saline and glucose infusion and monitor the patient closely. Blood pressure and fluid and electrolyte balance should be monitored over the next few days.

The oral LD₅₀ of neomycin sulfate in mouse is > 8 g/kg. The subcutaneous LD₅₀ is 200 mg/kg in rat and 190 mg/kg in mouse. The intraperitoneal LD₅₀ in mouse is 305 mg/kg. The oral Lowest published toxic dose (TDLo) in woman is 12600 mg/kg/7D.

Because of low absorption, acute overdosage from oral neomycin is not likely to occur. However, prolonged administration of neomycin should be avoided because of the possibility of some systemic absorption and the risk of neurotoxicity, ototoxicity, and/or nephrotoxicity. Hemodialysis will remove neomycin from the blood. While nephrotoxicity and ototoxicity have been reported in otherwise patients without compromised renal function, the risk for developing these toxicities is increased in patients with renal impairment. Like other aminoglycosides, neomycin may cause fetal harm and total irreversible bilateral congenital deafness when administered in pregnant women.

Precaution

Care must be taken while transferring patients from systemic steroid to Beclomethasone nasal spray if there is any reason to suppose that their adrenal function is impaired.

Predisposition to adrenocortical insufficiency. Admin with acidic drink in patients with achlorhydria. Pregnancy and lactation.

Interaction

Reduced absorption with antimuscarinics, antacids, H2-blockers, PPIs and sucralfate. Reduced plasma concentrations with rifampicin, isoniazid, efavirenz, nevirapine, phenytoin. May also reduce concentrations of isoniazid and rifampicin. May reduce efficacy of oral contraceptives. May increase serum levels of CYP3A4 substrates e.g. digoxin, oral anticoagulants, sildenafil, tacrolimus.

Volume of Distribution

Following intravenous administration, the steady-state volume of distribution was 20 L for beclomethasone dipropionate and 424 L for the active metabolite, beclomethasone-17-monopropionate.

Ketoconazole has an estimated volume of distribution of 25.41 L or 0.36 L/kg. It distributes widely among the tissues, reaching effective concentrations in the skin, tendons, tears, and saliva. Distribution to vaginal tissue produces concentrations 2.4 times lower than plasma. Penetration into the CNS, bone, and seminal fluid are minimal. Ketoconazole has been found to enter the breast milk and cross the placenta in animal studies.

The small fraction of absorbed neomycin is rapidly distributed in the tissues. The amount of systemically absorbed neomycin is reported to increase cumulatively with each repeated dose administered until a steady state is reached.

Elimination Route

Following oral inhalation of 320 mcg of beclomethasone dipropionate (BDP), the Cmax was 88 pg/mL and it was reached after 0.5 at post-administration. The mean Cmax of the major and most active metabolite, beclomethasone-17-monopropionate (17-BMP), was 1419 pg/mL at 0.7 hour post-dosing.

In another pharmacokinetic study, the AUC of BDP and 17-BMP were 6660 and 6185 pgxh/mL, respectively. The Cmax was 35356 pg/mL for BDP and 2633 pg/mL for 17-BMP, and and the median time to reach these concentrations (Tmax) was 0.2 hours. In the same study, the AUC of 17-BMP following oral and intranasal administration were 10158 and 3660 pgxh/mL, respectively. The Cmax of 17-BMP following oral and intranasal administration were 703 and 310 pg/mL, respectively, and the Tmax was 4 hours. The total bioavailability of 17-BMP following oral and intranasal administration were 41% and 44%, respectively.

Ketoconazole requires an acidic environment to become soluble in water. At pH values above 3 it becomes increasingly insoluble with about 10% entering solution in 1 h. At pH less than 3 dissolution is 85% complete in 5 min and entirely complete within 30 min. A single 200 mg oral dose produces a Cmax of 2.5-3 mcg/mL with a Tmax of 1-4 h. Administering ketoconazole with food consistently increases Cmax and delays Tmax but literature is contradictory regarding the effect on AUC, which may experience a small decrease. A bioavailablity of 76% has been reported for ketoconazole.

Neomycin is poorly absorbed from the gastrointestinal tract. Gastrointestinal absorption of the drug may be increased if inflammatory or ulcerative gastrointestinal disease is present.

Half Life

Following intravenous administration, the half life of beclomethasone dipropionate was 0.5 hours while the half life of the active metabolite 17-BMP was 2.7 hours. Following oral and intranasal administration, the half life of 17-BMP was 8.8 and 5.7 hours, respectively.

Ketoconazole experiences biphasic elimination with the first phase having a half-life of 2 hours and a terminal half life of 8 hours.

There is limited information on the half-life of neomycin.

Clearance

Following intravenous administration, the clearance of beclomethasone dipropionate and 17-BMP were 150 L/h and 120 L/h, respectively.

Ketoconazole has an estimated clearance of 8.66 L/h.

There is limited information on the clearance rate of neomycin.

Elimination Route

Regardless of the route of administration, beclomethasone dipropionate and its metabolites are predominantly excreted in the feces, with less than 10% of the drug and its metabolites being excreted in the urine.

Only 2-4% of the ketoconazole dose is eliminated unchanged in the urine. Over 95% is eliminated through hepatic metabolism.

The small absorbed fraction of neomycin is excreted by the kidney. The unabsorbed portion of the drug is excreted unchanged in the feces.

Pregnancy & Breastfeeding use

Beclomethasone should be used during pregnancy, if the potential benefit justifies the potential risks to fetus. In addition, as there is natural increase in corticosteroid production during pregnancy, most women will require a lower exogenous corticosteroid dose and many will not need corticosteroid treatment during pregnancy.

As other corticosteroids are excreted in human milk, caution should be exercised when Beclomethasone nasal spray is administered to a nursing woman.

Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.

Contraindication

Contraindicated in patients with a history of hypersensitivity to any of its components. Infections of the nasal passages and paranasal sinuses should be appropriately treated but do not constitute a specific contraindication to treatment with Beclomethasone nasal spray.

Hypersensitivity; preexisting liver disease. Concurrent use with CYP3A4 substrates e.g. HMG-CoA reductase inhibitors (e.g. lovastatin, simvastatin), midazolam, triazolam, cisapride, dofetilide, eplerenone, nisoldipine, pimozide, quinidine, terfenadine, astemizole, ergot alkaloids (e.g. ergotamine, dihydroergotamine).

Special Warning

Renal Impairment: Oral: No dosage adjustment needed.

Hepatic Impairment: Oral: Contraindicated.

Acute Overdose

Inhalation of excessive doses over a short time period may suppress hypothalamic pituitary adrenal (HPA) function, and no special emergency action need to be taken, rather treatment should be continued at recommended dose. HPA function recovers within one or two day
