How Betamethasone + Neomycin Sulphate works
Glucocorticoids inhibit neutrophil apoptosis and demargination, and inhibit NF-Kappa B and other inflammatory transcription factors. They also inhibit phospholipase A2, leading to decreased formation of arachidonic acid derivatives. In addition, glucocorticoids promote anti-inflammatory genes like interleukin-10.
Corticosteroids like betamethasone can act through nongenomic and genomic pathways. The genomic pathway is slower and occurs when glucocorticoids activate glucocorticoid receptors and initiate downstream effects that promote transcription of anti-inflammatory genes including phosphoenolpyruvate carboxykinase (PEPCK), IL-1-receptor antagonist, and tyrosine amino transferase (TAT). On the other hand, the nongenomic pathway is able to elicit a quicker response by modulating T-cell, platelet and monocyte activity through the use of existing membrane-bound receptors and second messengers.
Dosage
Betamethasone + Neomycin Sulphate dosage
Apply sparingly to the affected area 2 to 3 times daily until an improvement occurs. In children, course should be limited to 5 days
Side Effects
Burning, itching, irritation, dryness, folliculitis, hypertrychosis, acneiform eruptions, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae and miliaria may be reported.
Toxicity
Chronic high doses of glucocorticoids can lead to the development of cataracts, glaucoma, hypertension, water retention, hyperlipidemia, peptic ulcer, pancreatitis, myopathy, osteoporosis, mood changes, psychosis, dermal atrophy, allergy, acne, hypertrichosis, immune suppression, decreased resistance to infection, moon face, hyperglycemia, hypocalcemia, hypophosphatemia, metabolic acidosis, growth suppression, and secondary adrenal insufficiency. Overdose may be treated by adjusting the dose or stopping the corticosteroid as well as initiating symptomatic and supportive treatment.
Precaution
Long-term continuous topical therapy should be avoided where possible, particularly in infants and children. Infants and children up to four years should not be treated with topical steroids for longer than 3 weeks without medical review.
Interaction
Increased hyperglycaemia and hypokalaemia with thiazide diuretics. Increased incidence of peptic ulcer or GI bleeding with concurrent NSAIDs admin. Response to anticoagulants altered. Dose of antidiabetics and antihypertensives needs to be increased. Decreases serum concentration of salicylates and antimuscarinic agents.
Potentially Fatal: Reduced efficacy with concurrent use of carbamazepine, phenytoin, primidone, barbiturates and rifampicin. Enhanced effect in women taking oestrogens or oral contraceptives.
Volume of Distribution
In a study that included Indian women of reproductive age, the volume of distribution following a single intramuscular dose of betamethasone phosphate was 94,584±23,539 mL(s).
Elimination Route
The absorption and potency of any topical corticosteroid including betamethasone depends on the vehicle in which the steroid is delivered. For example, betamethasone dipropionate 0.05% ointment is classified as a highly potent topical steroid, while betamethasone dipropionate 0.05% cream or lotion is considered to be moderately potent.
There are several structural modifications that can determine the potency of a topical corticosteroid. For example, corticosteroids containing a halogen at specific carbons, or that contain esters are more potent due to enhanced lipophilicity. As such, there is a marked difference between topical products containing betamethasone dipropionate vs. betamethasone valerate. Betamethasone dipropionate contains 2 esters which enhances its potency, while betamethasone valerate has only one ester and is less potent.
It should be noted that the use of occlusive dressings with topical steroids significantly increases the absorption, increasing the risk for adverse effects.
Half Life
In a study that included Indian women of reproductive age, the half-life following a single intramuscular dose of betamethasone phosphate was 10.2 ± 2.5 hours.
Clearance
In a study that included Indian women of reproductive age, the CL/F following a single intramuscular dose of betamethasone phosphate was 6,466 ± 805 mL/hour.
Elimination Route
Corticosteroids are eliminated predominantly in the urine.
Pregnancy & Breastfeeding use
There are no adequate and well controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids and should not be used extensively for a prolonged period.
Contraindication
Acne vulgaris, Perioral dermatitis, Perianal and genital pruritus, Primary cutaneous viral infections (e.g. herpes simplex, chickenpox), Hypersensitivity to any component of the preparation.
Acute Overdose
Long-term intensive topical use may lead to systemic effects
Storage Condition
Protect from light. Do not freeze. Store between 15 °C and 30 °C.
