Carbocisteine reduces goblet cell hyperplasia and therefore plays a role in the management of disorders characterised by abnormal mucous. Carbocisteine loosens thick sputum effectively by reducing its viscosity and thereby helps to expectorate that mucus more easily from the respiratory tract. The mucolytic action happens in several mechanisms. It breaks the disulphide bonds, which cross-link certain glycoprotein molecules in the mucus, the mucus produced under the influence of Carbocisteine has high sialomucin and low fucomucin content. This combined effect ultimately reduces the viscosity of the sputum and increases its volume.

Due to its mucolytic effects, carbocisteine significantly reduces sputum viscosity, cough, dyspnea and fatigue. Additionally, it prevents pulmonary infections by decreasing accumulated mucus in the respiratory tract; this is especially beneficial in preventing exacerbations of COPD caused by bacteria and viruses. It has in-vitro anti-inflammatory activity with some demonstrated action against free radicals.

Cephalexin is a semisynthetic analogue of Cephalosporin C. It kills bacteria by interfering in the synthesis of the bacterial cell wall. Peptidoglycan is a heteropolymeric structure that provides the cell wall with mechanical stability. The final stage in the synthesis of peptidoglycan involves the completion of the cross-linking and the terminal glycine residue of the Pentaglycine Bridge is linked to the fourth residue of the pentapeptide (d-alanin). The transpeptidase enzyme that performs this step is inhibited by penicillins and cephalosporins. As a result the bacterial cell wall is weakened, the cell swells and then ruptures. Cephalexin is a first generation cephalosporin that is active by mouth.

Cephalexin (also called Cefalexin) is a first generation cephalosporin antibiotic. It is one of the most widely prescribed antibiotics, often used for the treatment of superficial infections that result as complications of minor wounds or lacerations. It is effective against most gram-positive bacteria through its inihibition of the cross linking reaction between N-acetyl muramicacid and N-acetylglucosamine in the cell wall, leading to cell lysis.

How Cecarb works

The hypersecretion of mucus characterizes serious respiratory conditions including asthma, cystic fibrosis (CF), and chronic obstructive pulmonary disease (COPD). It blocks bacterial adherence to cells, preventing pulmonary infections. Glycoproteins (fucomucins, sialomucins and sulfomucins) regulate the viscoelastic properties of bronchial mucus. Increased fucomucins can be found in the mucus of patients with COPD. Carbocisteine serves to restore equilibrium between sialomucins and fucomucins, likely by intracellular stimulation of sialyl transferase enzyme, thus reducing mucus viscosity.

A study found that L-carbocisteine can inhibit damage to cells by hydrogen peroxide (H2O2) by activating protein kinase B (Akt) phosphorylation, suggesting that carbocisteine may have antioxidant effects and prevent apoptosis of lung cells. There is some evidence that carbocisteine suppresses NF-κB and ERK1/2 MAPK signalling pathways, reducing TNF-alpha induced inflammation in the lungs, as well as other inflammatory pathways. An in-vitro study found that L-carbocisteine reduces intracellular adhesion molecule 1 (ICAM-1), inhibiting rhinovirus 14 infection, thereby reducing airway inflammation.

Cephalexin is a first generation cephalosporin antibiotic. Cephalosporins contain a beta lactam and dihydrothiazide. Unlike penicillins, cephalosprins are more resistant to the action of beta lactamase. Cephalexin inhibits bacterial cell wall synthesis, leading breakdown and eventualy cell death.

Dosage

Cecarb dosage

Adult: Initially, 2.25 g daily in divided doses, then 1.5 g daily in divided doses as condition improves.

Child: 2-5 year: 62.5-125 mg 4 times daily; 6-12 year 250 mg tid.

Should be taken with food.

Adult:

The usual dose is 250 mg to 500 mg every 6 hour.
For skin and soft tissue infections, streptococcal pharyngitis and uncomplicated cystitis, in patients over 15 years of age: 500 mg of the drug may be administered every 12 hour.
In severe or deep seated infections the dose can be increased up to 3 g to 6 g daily.

Children: The dosage range is 25-100 mg/kg/day in divided doses to a maximum of 4 g dailyChildren's Weight Recommended Dose:

10 kg (22 Ibs):62.5 mg to 125 mg qid or 125 mg to 250 mg bid
20 kg (44 Ibs):125 mg to 250 mg qid or 250 mg to 500 mg bid
40 kg (88 Ibs):250 mg to 500 mg qid or 500 mg to 1 g bid

For streptococcal pharyngitis, skin and soft tissue infections and in patients over 1 year of age the total daily dose may be divided and administered every 12 hour. In the therapy of otitis media 75-100 mg/kg/day in four divided doses may be required. In the treatment of β haemolytic streptococcal infections a therapeutic dosage of the drug should be given at least for 10 days.

Side Effects

Gastrointestinal discomfort, nausea, diarrhoea, gastrointestinal bleeding, palpitation, dizziness, headache, heartburn and skin rash may occur.

Side effects include nausea, vomiting, diarrhoea and abdominal discomfort. Symptoms of pseudomembranous colitis may appear either during or after antibiotic treatment. Skin rash, angio oedema, rise in serum aminotransferases, eosinophilia, neutropenia have been reported very rarely. Superinfection with resistant micro organisms, particularly candida may follow the treatment.

Toxicity

The oral LD50 of carbocisteine in rats is >15000 mg/kg. An overdose with carbocisteine is likely to result in gastrointestinal discomfort with nausea and vomiting.

Symptoms of overdose include blood in the urine, diarrhea, nausea, upper abdominal pain, and vomiting. An overdose is generally managed through supportive treatment as diuresis, dialysis, hemodialysis, and charcoal hemoperfusion are not well studied in this case.

The oral median lethal dose of cephalexin in rats is >5000 mg/kg. The oral LD50 in a monkey is >1g/kg and the lowest dose causing a toxic effect in humans is 14mg/kg.

Cephalexin has not been shown to be harmful in pregnancy and is not associated with teratogeniticy. Cephalexin is present in breast milk, though infants may be exposed to Label The effects of breast milk exposure to cephalexin have not been established and so caution must be exercised and the risk and benefit of cephalexin use in breastfeeding must be weighed.

Cephalexin has not been studied for carcinogenicity or mutagenicity. Cephalexin has no affect on fertility in rats.

Precaution

No specific precaution is recommended but Carbocisteine should be used with caution in patients with a recent history of peptic ulcer and recurrent gastrointestinal bleeding.

Cefalexin should be given with caution in patients with renal impairment. Under such condition, careful clinical observation should be made because safe dosage may be lower than the usually recommended. The urine of patients receiving Cefalexin may give a false positive reaction for glucose with copper reduction reagent. Positive results to Coombs’ test have been reported. Although there is no evidence of teratogenicity in animal tests, Cefalexin may be used during pregnancy when it is considered essential. Cefalexin is found in the milk of nursing mothers, hence caution should be taken when it is administered to nursing mothers.

Interaction

Neither hazardous nor therapeutically useful interactions have been reported.
