How Lupiderm Gm Plus 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.

Chloramphenicol is lipid-soluble, allowing it to diffuse through the bacterial cell membrane. It then reversibly binds to the L16 protein of the 50S subunit of bacterial ribosomes, where transfer of amino acids to growing peptide chains is prevented (perhaps by suppression of peptidyl transferase activity), thus inhibiting peptide bond formation and subsequent protein synthesis.

Clotrimazole acts primarily by damaging the permeability barrier in the cell membrane of fungi. Clotrimazole causes inhibition of ergosterol biosynthesis, an essential constituent of fungal cell membranes. If ergosterol synthesis is either completely or partially inhibited, the cell is no longer able to construct an intact and functional cell membrane ,. Because ergosterol directly promotes the growth of fungal cells in a hormone‐like fashion, rapid onset of the above events leads to dose-dependent inhibition of fungal growth .

Though decreased ergosterol, due to the inhibition of lanosterol 14-demethylase (also known as CYP51) is accepted to be primarily responsible for the antimycotic properties of clotrimazole, this drug also shows other pharmacological effects. These include the inhibition of sarcoplasmic reticulum Ca2+‐ATPase, depletion of intracellular calcium, and blocking of calcium‐dependent potassium channels and voltage‐dependent calcium channels . The action of clotrimazole on these targets accounts for other effects of this drug that are separate from its antimycotic activities .

Lidocaine is a local anesthetic of the amide type . It is used to provide local anesthesia by nerve blockade at various sites in the body . It does so by stabilizing the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action . In particular, the lidocaine agent acts on sodium ion channels located on the internal surface of nerve cell membranes . At these channels, neutral uncharged lidocaine molecules diffuse through neural sheaths into the axoplasm where they are subsequently ionized by joining with hydrogen ions . The resultant lidocaine cations are then capable of reversibly binding the sodium channels from the inside, keeping them locked in an open state that prevents nerve depolarization . As a result, with sufficient blockage, the membrane of the postsynaptic neuron will ultimately not depolarize and will thus fail to transmit an action potential . This facilitates an anesthetic effect by not merely preventing pain signals from propagating to the brain but by aborting their generation in the first place .

In addition to blocking conduction in nerve axons in the peripheral nervous system, lidocaine has important effects on the central nervous system and cardiovascular system . After absorption, lidocaine may cause stimulation of the CNS followed by depression and in the cardiovascular system, it acts primarily on the myocardium where it may produce decreases in electrical excitability, conduction rate, and force of contraction .

Side Effects

The following is a list of possible side effects that may occur from all constituting ingredients of Chloramphenicol Beclomethasone & Clotrimazole Ear Drops. This is not a comprehensive list. These side effects are possible but do not always occur. Some of the side effects may be rare but serious. Consult your doctor if you observe any of the following side effects, especially if they do not go away.

• Inflammation Of The Skin
• Irritation
• Itchy Rash
• Blisters
• Peeling Or Flaking Of The Skin
• Discomfort.

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.

Oral, mouse: LD₅₀ = 1500 mg/kg; Oral, rat: LD₅₀ = 2500 mg/kg. Toxic reactions including fatalities have occurred in the premature and newborn; the signs and symptoms associated with these reactions have been referred to as the gray syndrome. Symptoms include (in order of appearance) abdominal distension with or without emesis, progressive pallid cyanosis, vasomotor collapse frequently accompanied by irregular respiration, and death within a few hours of onset of these symptoms.

Symptoms of overdose include erythema, stinging, blistering, peeling, edema, pruritus, urticaria, burning, and general irritation of the skin, and cramps. As with all topical agents, skin sensitization may result .

Oral LD50 (rat): 708 mg/kg; Intraperitoneal LD50 (rat): 445 mg/kg; Subcutaneous LDLO (rat): 10 g/kg; Oral LD50 (mouse): 761 mg/kg; Subcutaneous LDLO (mouse): 10 g/kg; Intraperitoneal LD50 (mouse): 108 mg/kg;

Overdose

This drug poses no risk of acute intoxication, as it is unlikely to occur following a single vaginal or dermal application of an overdose (application over a large area under conditions favorable to absorption) or accidental oral ingestion. There is no specific antidote .

Effects on Fertility

No human studies of the effects of clotrimazole on fertility have been conducted; however, animal studies have not shown any effects on the drug on fertility .

Use in Pregnancy

There are limited data regarding the use of clotrimazole in pregnant women. Animal studies do not show direct or indirect harmful effects on reproduction. Although the topical application of clotrimazole may result in very low serum and tissue levels, the use of clotrimazole topical cream by pregnant women is not recommended unless it is advised by the prescribing physician. Clotrimazole topical cream should not be used in the first trimester of pregnancy unless it is considered by the physician to be essential to patient well-being .

Use in Breastfeeding

Available pharmacodynamic/toxicological studies in animals have shown excretion of clotrimazole/metabolites in breastmilk. Clotrimazole should not be administered during breastfeeding. Although the topical application of clotrimazole has resulted in very low serum and tissue levels, the use of clotrimazole topical cream by lactating women is not recommended unless it recommended by the prescribing physician .

Symptoms of overdose and/or acute systemic toxicity involves central nervous system toxicity that presents with symptoms of increasing severity . Patients may present initially with circumoral paraesthesia, numbness of the tongue, light-headedness, hyperacusis, and tinnitus . Visual disturbance and muscular tremors or muscle twitching are more serious and precede the onset of generalized convulsions . These signs must not be mistaken for neurotic behavior . Unconsciousness and grand mal convulsions may follow, which may last from a few seconds to several minutes . Hypoxia and hypercapnia occur rapidly following convulsions due to increased muscular activity, together with the interference with normal respiration and loss of the airway . In severe cases, apnoea may occur. Acidosis increases the toxic effects of local anesthetics . Effects on the cardiovascular system may be seen in severe cases . Hypotension, bradycardia, arrhythmia and cardiac arrest may occur as a result of high systemic concentrations, with potentially fatal outcome .

Pregnancy Category B has been established for the use of lidocaine in pregnancy, although there are no formal, adequate, and well-controlled studies in pregnant women . 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 . Ultimately, although animal studies have revealed no evidence of harm to the fetus, lidocaine should not be administered during early pregnancy unless the benefits are considered to outweigh the risks . Lidocaine readily crosses the placental barrier after epidural or intravenous administration to the mother . The ratio of umbilical to maternal venous concentration is 0.5 to 0.6 . The fetus appears to be capable of metabolizing lidocaine at term . The elimination half-life in the newborn of the drug received in utero is about three hours, compared with 100 minutes in the adult . Elevated lidocaine levels may persist in the newborn for at least 48 hours after delivery . Fetal bradycardia or tachycardia, neonatal bradycardia, hypotonia or respiratory depression may occur .

Local anesthetics rapidly cross the placenta and when used for epidural, paracervical, pudendal or caudal block anesthesia, can cause varying degrees of maternal, fetal and neonatal toxicity . The potential for toxicity depends upon the procedure performed, the type and amount of drug used, and the technique of drug administration . Adverse reactions in the parturient, fetus and neonate involve alterations of the central nervous system, peripheral vascular tone, and cardiac function .

Maternal hypotension has resulted from regional anesthesia . Local anesthetics produce vasodilation by blocking sympathetic nerves . Elevating the patient’s legs and positioning her on her left side will help prevent decreases in blood pressure . The fetal heart rate also should be monitored continuously, and electronic fetal monitoring is highly advisable .

Epidural, spinal, paracervical, or pudendal anesthesia may alter the forces of parturition through changes in uterine contractility or maternal expulsive efforts . In one study, paracervical block anesthesia was associated with a decrease in the mean duration of first stage labor and facilitation of cervical dilation . However, spinal and epidural anesthesia have also been reported to prolong the second stage of labor by removing the parturient’s reflex urge to bear down or by interfering with motor function . The use of obstetrical anesthesia may increase the need for forceps assistance .

The use of some local anesthetic drug products during labor and delivery may be followed by diminished muscle strength and tone for the first day or two of life . The long-term significance of these observations is unknown . Fetal bradycardia may occur in 20 to 30 percent of patients receiving paracervical nerve block anesthesia with the amide-type local anesthetics and may be associated with fetal acidosis . Fetal heart rate should always be monitored during paracervical anesthesia . The physician should weigh the possible advantages against risks when considering a paracervical block in prematurity, toxemia of pregnancy, and fetal distress . Careful adherence to the recommended dosage is of the utmost importance in obstetrical paracervical block . Failure to achieve adequate analgesia with recommended doses should arouse suspicion of intravascular or fetal intracranial injection . Cases compatible with unintended fetal intracranial injection of local anesthetic solution have been reported following intended paracervical or pudendal block or both. Babies so affected present with unexplained neonatal depression at birth, which correlates with high local anesthetic serum levels, and often manifest seizures within six hours . Prompt use of supportive measures combined with forced urinary excretion of the local anesthetic has been used successfully to manage this complication .

It is not known whether this drug is excreted in human milk . Because many drugs are excreted in human milk, caution should be exercised when lidocaine is administered to a nursing woman .

Dosages in children should be reduced, commensurate with age, body weight and physical condition .

The oral LD 50 of lidocaine HCl in non-fasted female rats is 459 (346-773) mg/kg (as the salt) and 214 (159-324) mg/kg (as the salt) in fasted female rats .

Interaction

Decreased effects of iron and vitamin B12 in anaemic patients. Phenobarbitone and rifampin reduce efficacy of chloramphenicol. Impairs the action of oral contraceptives.

There have been reports of a heat reaction when this medication used concomitantly with Sofradex drops in the ear.

Antagonism with polyene antibiotics.

May increase serum levels with cimetidine and propranolol. Increased risk of cardiac depression with β-blockers and other antiarrhythmics. Additive cardiac effects with IV phenytoin. Hypokalaemia caused by acetazolamide, loop diuretics and thiazides may antagonise effect of lidocaine. Dose requirements may be increased with long-term use of phenytoin and other enzyme-inducers.

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.

The topical form is minimally absorbed in the serum and tissues . Clotrimazole is a lipophilic drug , and has been shown to be secreted in breastmilk in animal studies . There are limited data available regarding the volume of distribution following oral troche administration.

The volume of distribution determined for lidocaine is 0.7 to 1.5 L/kg .

In particular, lidocaine is distributed throughout the total body water . Its rate of disappearance from the blood can be described by a two or possibly even three-compartment model . There is a rapid disappearance (alpha phase) which is believed to be related to uptake by rapidly equilibrating tissues (tissues with high vascular perfusion, for example) . The slower phase is related to distribution to slowly equilibrating tissues (beta phase) and to its metabolism and excretion (gamma phase) .

Lidocaine's distribution is ultimately throughout all body tissues . In general, the more highly perfused organs will show higher concentrations of the agent . The highest percentage of this drug will be found in skeletal muscle, mainly due to the mass of muscle rather than an affinity .

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.

Rapidly and completely absorbed from gastrointestinal tract following oral administration (bioavailability 80%). Well absorbed following intramuscular administration (bioavailability 70%). Intraocular and some systemic absorption also occurs after topical application to the eye.

Because clotrimazole is generally not significantly absorbed, drug interactions are not a major issue with its use .

In general, lidocaine is readily absorbed across mucous membranes and damaged skin but poorly through intact skin . The agent is quickly absorbed from the upper airway, tracheobronchial tree, and alveoli into the bloodstream . And although lidocaine is also well absorbed across the gastrointestinal tract the oral bioavailability is only about 35% as a result of a high degree of first-pass metabolism . After injection into tissues, lidocaine is also rapidly absorbed and the absorption rate is affected by both vascularity and the presence of tissue and fat capable of binding lidocaine in the particular tissues .

The concentration of lidocaine in the blood is subsequently affected by a variety of aspects, including its rate of absorption from the site of injection, the rate of tissue distribution, and the rate of metabolism and excretion . Subsequently, the systemic absorption of lidocaine is determined by the site of injection, the dosage given, and its pharmacological profile . The maximum blood concentration occurs following intercostal nerve blockade followed in order of decreasing concentration, the lumbar epidural space, brachial plexus site, and subcutaneous tissue . The total dose injected regardless of the site is the primary determinant of the absorption rate and blood levels achieved . There is a linear relationship between the amount of lidocaine injected and the resultant peak anesthetic blood levels .

Nevertheless, it has been observed that lidocaine hydrochloride is completely absorbed following parenteral administration, its rate of absorption depending also on lipid solubility and the presence or absence of a vasoconstrictor agent . Except for intravascular administration, the highest blood levels are obtained following intercostal nerve block and the lowest after subcutaneous administration .

Additionally, lidocaine crosses the blood-brain and placental barriers, presumably by passive diffusion .

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.

Half-life in adults with normal hepatic and renal function is 1.5 - 3.5 hours. In patients with impaired renal function half-life is 3 - 4 hours. In patients with severely impaired hepatic function half-life is 4.6 - 11.6 hours. Half-life in children 1 month to 16 years old is 3 - 6.5 hours, while half-life in infants 1 to 2 days old is 24 hours or longer and is highly variable, especially in low birth-weight infants.

The elimination half-life of lidocaine hydrochloride following an intravenous bolus injection is typically 1.5 to 2.0 hours . Because of the rapid rate at which lidocaine hydrochloride is metabolized, any condition that affects liver function may alter lidocaine HCl kinetics . The half-life may be prolonged two-fold or more in patients with liver dysfunction .

Clearance

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

The mean systemic clearance observed for intravenously administered lidocaine in a study of 15 adults was approximately 0.64 +/- 0.18 L/min .

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.

Mainly hepatic .

The excretion of unchanged lidocaine and its metabolites occurs predominantly via the kidney with less than 5% in the unchanged form appearing in the urine . The renal clearance is inversely related to its protein binding affinity and the pH of the urine . This suggests by the latter that excretion of lidocaine occurs by non-ionic diffusion .

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.

Pregnancy Category C. Either studies in animals have revealed adverse effects on the fetus (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 fetus.

Pregnancy:Clotrimazole is recommended during pregnancy only after first consulting a doctor.

Lactation:Because systemic absorption of clotrimazole following topical application is marginal, there should be no risk for the infant during lactation.

Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).

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.

History of hypersensitivity or toxic reaction to the drug; pregnancy, lactation; porphyria; parenteral admin for minor infections or as prophylaxis; preexisting bone marrow depression or blood dyscrasias.

Hypersensitivity to clotrimazole.

Hypovolaemia, complete heart block, Adam-Stokes syndrome, Wolff-Parkinson-White syndrome. Must not be applied to inflamed or injured skin.

Special Warning

Hepatic Impairment Parenteral: Dosage reduction may be needed.

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

Supportive measures should be taken incase of accidental oral ingestion.

In case of accidental oral ingestion, supportive measures should be taken.

Symptoms: Severe hypotension, asystole, bradycardia, apnoea, seizures, coma, cardiac arrest, resp arrest and death.

Management: Maintain oxygenation, stop convulsion and support the circulation.

Storage Condition

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.
