How Monamox Br Dry works

Amoxicillin competitively inhibits penicillin-binding protein 1 and other high molecular weight penicillin binding proteins. Penicillin bind proteins are responsible for glycosyltransferase and transpeptidase reactions that lead to cross-linking of D-alanine and D-aspartic acid in bacterial cell walls. Without the action of penicillin binding proteins, bacteria upregulate autolytic enzymes and are unable to build and repair the cell wall, leading to bacteriocidal action.

Inflammation of the airways, increased mucus secretion, and altered mucociliary clearance are the hallmarks of various diseases of the respiratory tract. Mucus clearance is necessary for lung health; bromhexine aids in mucus clearance by reducing the viscosity of mucus and activating the ciliary epithelium, allowing secretions to be expelled from the respiratory tract.

Recent have studies have demonstrated that bromhexine inhibits the transmembrane serine protease 2 receptor (TMPRSS2) in humans. Activation of TMPRSS2 plays an important role in viral respiratory diseases such as influenza A and Middle East Respiratory Syndrome (MERS). Inhibition of receptor activation and viral entry by bromhexine may be effective in preventing or treating various respiratory illnesses, including COVID-19. In vitro studies have suggested the action of ambroxol (a metabolite of bromhexine) on the angiogensin-converting enzyme receptor 2 (ACE2), prevents entry of the viral envelope-anchored spike glycoprotein of SARS-Cov-2 into alveolar cells or increases the secretion of surfactant, preventing viral entry.

Side Effects

Side effects are mild, rare and infrequent. As with other penicillins, it may induce diarrhea, indigestion or skin rashes that usually stop during treatment and rarely calls for discontinuation of therapy.

Gastrointestinal side-effects may occur occasionally with Bromhexine and a transient rise in serum aminotransferase values has been reported. Other reported adverse effects include headache, dizziness, sweating and skin rash.

Toxicity

Patients experiencing an overdose may present with hematuria, oliguria, abdominal pain, acute renal failure, vomiting, diarrhea, rash, hyperactivity, and drowsiness. Treat overdose with symptomatic and supportive treatment, which may include emesis or hemodialysis.

The oral LD50 of bromhexine in rats is 6 g/kg. The observed symptoms of accidental overdose with bromhexine are consistent with the known adverse effects of bromhexine, including headache, nausea, and vomiting, among other symptoms. Provide symptomatic treatment and contact poison control services if an overdose is confirmed or suspected.

Precaution

In renal impairment, the excretion of antibiotic will be delayed and depending on the degree of impairment it may be necessary to reduce the total daily dose.

Since mucolytics may disrupt the gastric mucosa so Bromhexine should be used with care in patients with a history of peptic ulceration.

Interaction

The simultaneous use of Amoxicillin and an oral contraceptive might cause breakthrough bleeding or pregnancy on rare occasions. Concurrent administration of probenecid delays the excretion of Amoxicillin.

Volume of Distribution

The central volume of distribution of amoxicillin is 27.7L.

After intravenous administration in a pharmacokinetic study, bromhexine was found to be widely distributed. Bromhexine is known to cross the blood-brain barrier; small concentrations may cross the placenta. The average volume of distribution of bromhexine was 1209 ± 206 L (19 L/kg). Lung tissue concentrations of bromhexine two hours after a dose were 1.5 to 3.2 times higher in bronchial tissues than plasma concentrations. Pulmonary parynchema concentrations were 3.4 to 5.9 times higher when compared to plasma concentrations.

Elimination Route

Amoxicillin is approximately 60% bioavailable. A 250mg dose of oral amoxicillin reaches a C_max 3.93±1.13mg/L with a T_max 1.31±0.33h and an AUC of 27.29±4.72mg*h/L. A 875mg dose of oral amoxicillin reaches a C_max 11.21±3.42mg/L with a T_max 1.52±0.40h and an AUC of 55.04±12.68mg*h/L.

After oral administration, bromhexine demonstrates linear pharmacokinetics when given in doses of 8-32 mg. Bromhexine is readily absorbed in the gastrointestinal tract at a rapid rate. This drug undergoes extensive first-pass effect in the range of 75-80%. The bioavailability is therefore reduced to approximately 22-27%.

Half Life

The half life of amoxicillin is 61.3 minutes.

Following single oral doses ranging from 8 and 32 mg, the terminal half-life of bromhexine has been measured between 6.6 and 31.4 hours.

Clearance

The mean clearance of amoxicillin is 21.3L/h.

The clearance of bromhexine ranges from 843-1073 mL/min, within the range of the hepatic circulation.

Elimination Route

125mg to 1g doses of amoxicillin are 70-78% eliminated in the urine after 6 hours.

After a dose of bromhexine was administered during a pharmacokinetic study, approximately 97% of the radiolabeled dose was detected in the urine; under 1% was detected as the parent drug.

Pregnancy & Breastfeeding use

Because of its lack of teratogenicity, Amoxicillin can beused safely throughout pregnancy at the normal adult dose. The small amount of Amoxicillin secreted in maternal milk rarely causes problem in the infant. It can therefore be used safely during lactation in most instances.

Pregnancy Category B. Bromhexine has been taken by a large number of pregnant women and women of child bearing age without any proven increase in the frequency of malformations or other direct or indirect harmful effects on the fetus having been observed.

It is not known whether bromhexine is excreted in breast milk or whether it has a harmful effect on the breastfeeding infant. Therefore it is not recommended for breast feeding mothers unless the potential benefits to the patient are weighed against the possible risk to the infant.

Contraindication

Amoxicillin is contraindicated for patients hypersensitive to penicillin, infectious mononucleosis, neonatal period or babies born of mothers hypersensitive to penicillin

Contraindicated to those who are hypersensitive to Bromhexine Hydrochloride.

Acute Overdose

If encountered, gastro-intestinal symptoms and disturbance of the fluid and electrolyte balance may be evident. They may be treated symptomatically and supportive with attention to the water/ electrolyte balance. In the absence of an adequate fluid intake and urinary output, crystalluria is a possibility and the antibiotic may be removed from the circulation by haemodialysis. Oral administration can cause gastro intestinal symptoms such as transient diarrhoea, nausea and colic which are dose related and a result of local irritation not toxicity.

Storage Condition

Store in a cool & dry place protected from light. Amoxicillin suspension and drops should be freshly prepared, stored in a cool dry place preferably in a refrigerator. Reconstituted suspension and drops should be used within 5 days if kept at room temperature or within 7 days if kept in a refrigerator.

Store below 25° C. Protect from light. Keep the container tightly closed.
