Mucosyn Uses, Dosage, Side Effects, Food Interaction and all others data.

Ambroxol is a metabolite of Bromhexine. It possesses mucokinetic (improvement in mucus transport) and secretolytic (liquefies secretions) properties. Ambroxol stimulates the serous cells of the glands of the mucous membrane of bronchi, increasing the content of mucus secretion. The mucolytic effect is associated with depolymerization and splitting of mucoproteins and mucopolysaccharide fibres, which leads to reduction in the viscosity of mucus. Expectoration of mucus is facilitated and breathing is eased considerably. Ambroxol stimulates production of phospholipids of surfactant by alveolar cells. Ambroxol has anti-inflammatory properties. In patients with COPD, it improves airway patency. Beside these, Ambroxol also exhibits anti-oxidant activity. Long-term use is possible because of the good tolerability of the preparation.

Levofloxacin exerts antibacterial action by inhibiting bacterial topoisomerase IV and DNA gyrase, the enzymes required for DNA replication, transcription repair and recombination. It has in vitro activity against a wide range of gm-ve and gm+ve microorganisms.

Levofloxacin is bactericidal and exerts its antimicrobial effects via inhibition of bacterial DNA replication. It has a relatively long duration of action in comparison with other antibiotics that allows for once or twice daily dosing. Levofloxacin is associated with QTc-interval prolongation and should be used with caution in patients with other risk factors for prolongation (e.g. hypokalemia, concomitant medications).

Levofloxacin has demonstrated in vitro activity against a number of aerobic gram-positive and gram-negative bacteria and may carry some activity against certain species of anaerobic bacteria and other pathogens such as Chlamydia and Legionella. Resistance to levofloxacin may develop, and is generally due to mutations in DNA gyrase or topoisomerase IV, or via alterations to drug efflux. Cross-resistance may occur between levofloxacin and other fluoroquinolones, but is unlikely to develop between levofloxacin and other antibiotic classes (e.g. macrolides) due to significant differences in chemical structure and mechanism of action.

As antimicrobial susceptibility patterns are geographically distinct, local antibiograms should be consulted to ensure adequate coverage of relevant pathogens prior to use.

How Mucosyn works

Ambroxol is a mucolytic agent. Excessive Nitric oxide (NO) is associated with inflammatory and some other disturbances of airways function. NO enhances the activation of soluble guanylate cyclase and cGMP accumulation. Ambroxol has been shown to inhibit the NO-dependent activation of soluble guanylate cyclase. It is also possible that the inhibition of NO-dependent activation of soluble guanylate cyclase can suppress the excessive mucus secretion, therefore it lowers the phlegm viscosity and improves the mucociliary transport of bronchial secretions.

Levofloxacin, like other fluoroquinolone antibiotics, exerts its antimicrobial activity via the inhibition of two key bacterial enzymes: DNA gyrase and topoisomerase IV. Both targets are type II topoisomerases, but have unique functions within the bacterial cell. DNA gyrase is an enzyme found only in bacteria that introduces negative supercoils into DNA during replication - this helps to relieve torsional strain caused by the introduction of positive supercoils during replication, and these negative supercoils are essential for chromosome condensation and the promotion of transcription initiation. It is comprised of four subunits (two A subunits and two B subunits) of which the A subunits appear to be the target of fluoroquinolone antibiotics. Bacterial topoisomerase IV, in addition to contributing to the relaxation of positive supercoils, is essential at the terminal stages of DNA replication and functions to “unlink” newly replicated chromosomes to allow for the completion of cell division.

Inhibition of these enzymes by levofloxacin likely occurs via complexation with the topoisomerase enzymes. The end result is a blockade of DNA replication, thus inhibiting cell division and resulting in cell death.

The infusion time must be at least 30 minutes for 250 mg or 60 minutes for 500 mg Levofloxacin solution for infusion. It is possible to switch from an initial intravenous application to the oral route at the same dosage after a few days.

Side Effects

Gastrointestinal side-effects like epigastric pain, gastric fullness may occur occasionally. Rarely allergic responses such as eruption, urticaria or angioneurotic edema may occur.

The most frequently reported adverse events were headache and a taste disturbance following instillation. Other adverse events included decreased/blurred vision, diarrhea, dyspepsia, fever, infection, instillation site irritation/discomfort, ocular infection, nausea, ocular pain/discomfort, and throat irritation.

Toxicity

The LD₅₀ following oral administration in mice and rats is 1803 mg/kg and 1478 mg/kg, respectively.

Levofloxacin exhibits low potential for acute toxicity - following a single high dose of levofloxacin in several different test animals (e.g. mice, rats, monkeys) observed symptoms included ataxia, ptosis, decreased motor activity, dyspnea, tremors, and convulsions. Treatment of acute overdosage should involve stomach emptying (e.g. with activated charcoal) and general supportive measures. Consider monitoring of the patient's ECG to ensure QTc values remain within range. Levofloxacin is not efficiently removed by dialysis (peritoneal or hemodialysis) and is therefore of little benefit in cases of overdose.

Precaution

Ambroxol should be given cautiously to patients with gastric and duodenal ulceration or convulsive disorders. Patients with hepatic and renal insufficiency should take it with caution.

The following measures should be taken during administration of Levofloxacin: While taking Levofloxacin adequate amount of water should be drunk to avoid risk of crystalluria. Dose adjustment should be exercised during Levofloxacin ingestion in presence of renal insufficiency & hepatic insufficiency.

While taking Levofloxacin adequate amount of water should be drunk to avoid risk of crystalluria. Dose adjustment should be exercised during Levofloxacin ingestion in presence of renal insufficiency & hepatic insufficiency.

Infusion of fluid should be immediately discontinued if rigor arises for any reason during the process. Do not use if the solution is cloudy, contains particles or after expiry date.

If an allergic reaction to levofloxacin occurs, discontinue the drug. Serious acute hypersensitivity reactions may require immediate emergency treatment. Oxygen and airway management should be administered as clinically indicated.

Prolonged use may result in overgrowth of non-susceptible organisms, including fungi. If superinfection occurs, discontinue use and institute alternative therapy. Patients should be advised not to wear contact lenses if they have signs and symptoms of corneal ulcer. Avoid contaminating the applicator tip with material from the eye, fingers or other source.

Interaction

Ambroxol has no interaction with cardioactive glycosides, corticosteroids, bronchodilators, diuretics and antibiotics (normally used in the treatment of bronchopulmonary affections). But Ambroxol should not be taken simultaneously with antitussives (e.g. Codeine) because mucus, which has been liquefied by Ambroxol, might not be expectorated.

Specific drug interaction studies have not been conducted with this drug. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, and enhance the effects of the oral anticoagulant warfarin and its derivatives, and has been associated with transient elevations in serum creatinine in patients receiving systemic cyclosporine concomitantly.

Volume of Distribution

Levofloxacin is widely distributed in the body, with an average volume of distribution following oral administration between 1.09-1.26 L/kg (~89-112 L). Concentrations in many tissues and fluids may exceed those observed in plasma. Levofloxacin is known to penetrate well into skin tissue, fluids (e.g. blisters), lung tissue, and prostatic tissue, amongst others.

Elimination Route

Rapid and almost complete.

Absorption of levofloxacin following oral administration is rapid and essentially complete, with an oral bioavailability of approximately 99%. Due to its nearly complete absorption, the intravenous and oral formulations of levofloxacin may be interchangeable. The T_max is generally attained 1-2 hours following administration and the C_max is proportional to the given dose - an intravenous dose of 500mg infused over 60 minutes resulted in a C_max of 6.2 ± 1.0 µg/mL whereas a 750mg dose infused over 90 minutes resulted in a C_max of 11.5 ± 4.0 µg/mL. Oral administration with food prolongs the T_max by approximately 1 hour and slightly decreases the C_max, but these changes are not likely to be clinically significant.

Systemic absorption following oral inhalation is approximately 50% lower than that observed following oral administration.

Half Life

7-12 hours

The average terminal elimination half-life of levofloxacin is 6-8 hours.

Clearance

The average apparent total body clearance of levofloxacin ranges from 8.64-13.56 L/h, and its renal clearance ranges from 5.76-8.52 L/h. The relative similarity of these ranges indicates a small degree of non-renal clearance.

Elimination Route

The majority of administered levofloxacin is excreted unchanged in the urine. Following the administration of a single oral dose of levofloxacin, approximately 87% was eliminated unchanged in the urine within 48 hours and less than 4% was eliminated in the feces within 72 hours.

Pregnancy & Breastfeeding use

Pregnancy: Teratogenic and fetal toxicity studies have shown no harmful effect of Ambroxol. However, it is advised not to use during pregnancy, especially in the 1st trimester.

Lactation: Safety during lactation has not been established.

Levofloxacin is not recommended for use during pregnancy or nursing, as the effects on the unborn child or nursing infant are unknown.

Contraindication

Contraindicated in known hypersensitivity to Ambroxol or Bromhexine.

Levofloxacin is contraindicated in patients with a history of hypersensitivity to Levofloxacin, quinolone antimicrobial agents, or any other components of this product.

Special Warning

Use in Children: From clinical studies, it is evident that Levofloxacin can be used in children aged as low as 6 months.The usual dose for children in community acquired pneumonia (CAP) is-

Children aged 6 months to less than 5 years: 10 mg/kg b.i.d. (up to 500 mg per day) for 10 days.
Children aged 5 years to 16 years: 10 mg/kg q.d. (up to 500 mg per day) for 10 days.

The usual dose for children in recurrent or persistent Acute Otitis Media (AOM) is Children aged 6 months to less than 5 years: 10 mg/kg per day (maximum dose: 500 mg/day) given twice daily for 10 days.

Acute Overdose

Levofloxacin exhibits a low potential for acute toxicity. However, in the events of an acute overdosage, the stomach should be emptied. The patients should be kept under observation and appropriate hydration should be maintained.
