Product releases lidocaine to stabilize the neuronal membrane by inhibiting the ionic fluxes required for initiation and conduction of impulses, thereby effecting local anesthetic action. Hydrocortisone acetate provides relief of inflammatory and pruritic manifestations of corticosteroid responsive dermatoses.
Lidocaine may be absorbed following topical
administration to mucous membranes, its rate and extent of absorption
depending upon the specific site of application, duration of exposure,
concentration, and total dosage. In general, the rate of absorption of
local anesthetic agents following topical application occurs most
rapidly after intratracheal administration. Lidocaine is also
well-absorbed from the gastrointestinal tract, but little intact drug
appears in the circulation because of biotransformation of the liver.
Lidocaine
is metabolized rapidly by the liver, and metabolites and unchanged drug
are excreted by the kidneys. Biotransformation includes oxidative
N-dealkylation, ring hydroxylation, cleavage of the amide linkage, and
conjungation. N-dealkylation, a major pathway of biotransformation,
yields the metabolites monoethylglycinexylidide and glycinexylidide. The
pharmacological/toxicological actions of these metabolites are similar
to, but less potent than, those of lidocaine. Approximately 90% of
lidocaine administered is excreted in the form of various metabolites,
and less than 10% is excreted unchanged. The primary metabolite in
urine is a conjugate of 4-hydroxy-2, 6-dimethylaniline.
The
plasma binding of lidocaine is dependent of drug concentration, and the
fraction bound decreases with increasing concentration. At
concentrations of 1 to 4 g of free base per mL, 60 to 80 percent of
lidocaine is protein bound. Binding is also dependent on the plasma
concentration of the alpha-1-acid-glycoprotein.
Lidocaine crosses the blood-brain and placental barriers, presumably by passive diffusion.
Studies
of lidocaine metabolism following intravenous bolus injections have
shown that the elimination half-life of this agent is typically 1.5 to
2 hours. Because of the rapid rate at which lidocaine is metabolized,
any condition that affects liver function may alter lidocaine kinetics.
The half-life may be prolonged two-fold or more in patients with liver
dysfunction. Renal dysfunction does not affect lidocaine kinetics but
may increase the accumulation of metabolites.
Factors such as
acidosis and the use of CNS stimulants and depressants affect the CNS
levels of lidocaine required to produce overt systemic effects.
Objective adverse manifestations become increasingly apparent with
increasing venous plasma levels above 6 g free base per mL. In the
rhesus monkey arterial blood levels of 18-21 g/mL have been shown to be the threshold for convulsive activity.
The extent of percutaneous
absorption of topical corticosteroids is determined by many factors
including the vehicle, the integrity of the epidermal barrier, and the
use of occlusive dressings.
Topical corticosteroids can be
absorbed from normal intact skin. Inflammation and/or other disease
processes in the skin increase percutaneous absorption. Occlusive
dressings substantially increase the percutaneous absorption of topical
corticosteroids. Thus, occlusive dressings may be a valuable
therapeutic adjunct for treatment of resistant dermatoses.
Once
absorbed through the skin, topical corticosteroids are handled through
pharmacokinetic pathways similar to systemically administered
corticosteroids. Corticosteroids are bound to plasma protein in varying
degrees. Corticosteroids are metabolized primarily in the liver and are
then excreted by the kidneys. Some of the topical corticosteroids and
their metabolites are also excreted into the bile.
Product should not be used in patients with a history of sensitivity to any of its ingredients or adverse reactions to lidocaine or amide anesthetics, which usually do not cross-react with “caine” ester type anesthetics. If excessive irritation and significant worsening occur, discontinue use and seek the advice of your physician. Product and topical lidocaine should be used cautiously in those with impaired liver function, as well as the very ill or very elderly and those with significant liver disease. Product should be used with caution in patients receiving antiarrhythmic drugs of Class I since the adverse effects are additive and generally synergistic. Product is contraindicated for tuberculous or fungal lesions or skin vaccinia, varicella and acute herpes simplex. Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation.
For external use only. Not for ophthalmic use. Product and used applicators could harm small children if chewed or swallowed.
Keep out of reach of children.
Topical
formulations of lidocaine may be absorbed to a greater extent through
mucous membranes and abraded, fissured or irritated skin than through
intact skin. Product should not be ingested or applied into the mouth,
inside of the nose or in the eyes. Product should not be used in the
ears. Any situation where lidocaine penetrates beyond the tympanic
membrane into the middle ear is contraindicted because of ototoxicty
associated with lidocaine observed in animals when instilled in the
middle ear. Product should not come into contact with the eye or be
applied into the eye because of the risk of severe eye irritation and
the loss of eye surface sensation, which reduces protective reflexes and
can lead to corneal irritation and possibly abrasion. If eye contact
occurs, rinse out the eye immediately with saline or water and protect
the eye surface until sensation is restored.
If irritation or sensitivity occurs or infection appears, discontinue use and institute appropriate therapy. If extensive areas are treated, the possibility of systemic absorption exists. Systemic absorption of topical steroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestation of Cushing’s syndrome, hyperglycemia, and glycosuria in some patients. Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings. Therefore, patients receiving a large dose of potent topical steroids applied to a large surface area, or under an occlusive dressing, should be evaluated periodically for evidence of HPA axis suppression. If noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Recovery of the HPA axis function is generally prompt and complete upon discontinuation of the drug. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. Children may absorb proportionately larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity. If irritation develops, topical steroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled.
Long-term animal studies have not been performed to evaluate the carcinogenic potential or the effect on fertility of topical corticosteroids. Studies to determine mutagenicity with prednisolone and hydrocortisone have revealed negative results. Studies of lidocaine in animals to evaluate the carcinogenic and mutagenic potential of the effect on fertility have not been conducted.
Pregnancy Category C Reproduction studies have been performed for lidocaine in rats at doses up to 6.6 times the human dose and have revealed no evidence of harm to the fetus caused by lidocaine. There are, however, no adequate and well-controlled studies in pregnant women. Animal reproduction studies are not always predictive of human response. General consideration should be given to this fact before administering lidocaine to women of childbearing potential, especially during early pregnancy when maximum organogenesis takes place. Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts or for prolonged periods of time.
Apply product to the affected area(s) twice daily or as directed by a physician. Product should not be used in excess of recommendations or for prolonged use in the anal canal. If the condition does not respond to repeated courses of product or should worsen, discontinue use and seek the advice of your physician.
Products without Applicators: Remove the child-resistant cap and foil seal from the tube. Apply a thin film to the affected area. Replace the cap after use.
Products with Single-Use Tubes and Applicators: Tear open one cleansing wipe packet (if the product kit contains such item), gently clean the affected area and discard the used cleansing wipe. Remove the child-resistant cap and foil seal from one tube and firmly screw one applicator onto the tube. Do not over tighten. Squeeze the tube to fill the applicator until a small amount of cream/gel comes out of and lubricates the applicator openings. Gently insert the applicator tip with attached tube into anal area. Continue squeezing the body of the tube as it is moved around the areas of discomfort, and lastly, around and in the anal opening (if directed by physician).
Do not completely insert the applicator and tube into the anus or insert deep into the rectum. Do not insert a loose applicator tip into the anus or rectum. Once application is completed, both the tube and applicator should be gently removed and discarded.
