How Nystatin/Chlorhexidine hydrochloride/Hydrocortisone works

The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation.[A187463] Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days.[A187463]

Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10.[A187463]

Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive.[A187463] High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.[A187463]

Nystatin is a channel-forming ionophore, meaning it exerts its therapeutic effect via formation of a membrane-spanning pore in the fungal plasma membrane. The formation of this pore results in a change in membrane permeability that allows for leakage of intracellular contents and the subsequent disruption of electrochemical gradients necessary for proper cell function. Selectivity for fungal cells over mammalian cells is due to nystatin’s greater binding affinity for ergosterol, a key sterol found in fungal cell walls, as opposed to its mammalian counterpart, cholesterol.

Dosage

Nystatin/Chlorhexidine hydrochloride/Hydrocortisone dosage

Tablet: The initial dosage of Hydrocortisone Tablets may vary from 20 mg to 240 mg of hydrocortisone per day depending on the specific disease entity being treated. In situations of less severity, lower doses will generally suffice, while in selected patients higher initial doses may be required. The initial dosage should be maintained or adjusted until a satisfactory response is noted. If after a reasonable period of time there is a lack of satisfactory clinical response, Hydrocortisone Tablets should be discontinued and the patient transferred to other appropriate therapy.

It should be emphasized that dosage requirements are variable and must be individualized on the basis of the disease under treatment and the response of the patients.After a favorable response is noted, the proper maintenance dosage should be determined by decreasing the initial drug dosage in small decrements at appropriate time intervals until the lowest dosage which will maintain an adequate clinical response. It should be kept in mind that constant monitoring is needed in regard to drug dosage. If, after long-term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually, rather than abruptly.

Injection:

• Adult: By IM injection or slow IV injection or infusion. The initial dose of Hydrocortisone sterile powder is 100 mg to 500 mg, depending on the severity of the condition. This dose may be repeated at intervals of 2, 4 or 6 hours as indicated by the patient's response and clinical condition.
• Children: By slow IV injection, up to 1 year 25 mg, 1-5 years 50 mg, 6-12 years 100 mg.

Children:

• In intestinal and oral candidiasis (thrush): 1,00,000 units (1 ml) should be dropped into the mouth four times daily.The longer the suspension is kept in contact with the affected area in the mouth, before swallowing, the greater will be its effect.
• For prophylaxis in the newborn:The suggested dose is 1,00,000 units (1 ml) once daily or as prescribed by the physician.

Adult:

• For the treatment of intestinal or esophageal candidiasis: 5,00,000 units (5 ml) by mouth 3 or 4 times daily. The dose may be doubled, if required.
• For prophylaxis of intestinal candidiasis in adults: 10,00,000 units (10 ml) daily.
• For prophylaxis to suppress the over growth of Candida albicans in patients receiving broad spectrum antibiotic therapy: 10,00,000 units (10 ml) daily.
• For the treatment of dental sores and oral infection: 1,00,000 units (1 ml) suspension should be dropped into the mouth four times daily.

Elderly: Older people with intestinal candidiasis who are unable to swallow tablets should be given 5,00,000 units (5 ml) suspension four times daily.

Adults and Pediatric Patients (Neonates and Older): Apply liberally to affected areas twice daily or as indicated until healing is complete.

Pediatric Use: Safety and effectiveness have been established in the pediatric population from birth to 16 years.

Geriatric Use: Clinical studies with nystatin cream did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently than younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

Side Effects

Hydrocortisone is generally well tolerated except in prolonged high doses. It may cause cardiac arrhythmia, esophageal candidiasis, menstrual irregularity, decreased carbohydrate & glucose tolerance, fluid retention, increased appetite, weight gain, euphoria, mood swings, depression, insomnia, acne etc.

Nystatin cream: The frequency of adverse events reported in patients using nystatin cream is less than 0.1%. The more common events that were reported include allergic reactions, burning, itching, rash, eczema, and pain on application.

Nystatin tablet: Nausea, vomiting and diarrhoea have occasionally been reported with high doses of Nystatin. No systemic effects or allergic reactions have been associated with its oral dose.

Toxicity

Data regarding acute overdoses of glucocorticoids are rare. Chronic high doses of glucocorticoids can lead to the development of cataract, 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.

The oral LD₅₀ in rats is 10 g/kg. There have been no reports of serious toxic effects following overdosage of nystatin - doses in excess of five million units daily have resulted in nausea and gastrointestinal upset with no other associated effects.

Precaution

Hydrocortisone should be used with caution in patients with a history of peptic ulceration as it increases the incidence of peptic ulceration. This drug should be used with caution in patients with congestive heart failure, hypertension, glaucoma, diabetic mellitus and epilepsy.

Nystatin cream should not be used for the treatment of systemic, oral, intravaginal or ophthalmic infections. If irritation or sensitization develops, treatment should be discontinued and appropriate measures taken as indicated. It is recommended that KOH smears, cultures, or other diagnostic methods be used to confirm the diagnosis of cutaneous or mucocutaneous candidiasis and to rule out infection caused by other pathogens.

Absorption from the gastrointestinal tract is negligible, therefore no special precaution is required to apply in pregnancy and lactation

Interaction

Drug interaction of hydrocortisone has been reported with amphotericin B, potassium-depleting agents, macrolide antibiotics, warfarin, antidiabetics, isoniazid, digitalis glycosides, estrogens, barbiturates, phenytoin, carbamazepine, ketoconazole, aspirin etc.

Volume of Distribution

Total hydrocortisone has a volume of distribution of 39.82L, while the free fraction has a volume of distribution of 474.38L.

Nystatin is not absorbed into the systemic circulation and thus does not undergo distribution.

Elimination Route

Oral hydrocortisone at a dose of 0.2-0.3mg/kg/day reached a mean C_max of 32.69nmol/L with a mean AUC of 90.63h*nmol/L A 0.4-0.6mg/kg/day dose reached a mean C_max of 70.81nmol/L with a mean AUC of 199.11h*nmol/L. However, the pharmacokinetics of hydrocortisone can vary by 10 times from patient to patient.

Topical hydrocortisone cream is 4-19% bioavailable[8546995] with a T_max of 24h.

Hydrocortisone retention enemas are have a bioavailability of 0.810 for slow absorbers and 0.502 in rapid absorbers. Slow absorbers take up hydrocortisone at a rate of 0.361±0.255/h while fast absorbers take up hydrocortisone at a rate of 1.05±0.255/h.

A 20mg IV dose of hydrocortisone has an AUC of 1163±277ng*h/mL.

Systemic absorption of nystatin is minimal following oral administration, and no detectable plasma concentrations are attained following topical or vaginal administration.

Half Life

Total hydrocortisone via the oral route has a half life of 2.15h while the free fraction has a half life of 1.39h. A 20mg IV dose of hydrocortisone has a terminal half life of 1.9±0.4h.

Clearance

Total hydrocortisone by the oral route has a mean clearance of 12.85L/h, while the free fraction has a mean clearance of 235.78L/h. A 20mg IV dose of hydrocortisone has a clearance of 18.2±4.2L/h.

Elimination Route

Corticosteroids are eliminated predominantly in the urine.[A187436] However, data regarding the exact proportion is not readily available.

The majority of orally administered nystatin is eliminated unchanged in the feces.

Pregnancy & Breastfeeding use

Pregnancy category C. Corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Use in nursing mother: Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Because of the potential for serious adverse reactions in nursing infants from corticosteroids, a decision should be made whether to continue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Pregnancy Category C. Animal reproduction studies have not been conducted with any nystatin cream. It also is not known whether this cream can cause fetal harm when used by a pregnant woman or can affect reproductive capacity. Nystatin cream should be prescribed for a pregnant woman only if the potential benefit to the mother outweighs the potential risk to the fetus.

Nursing Mothers: It is not known whether nystatin is excreted in human milk. Caution should be exercised when nystatin is prescribed for a nursing woman.
