Guamil
Guamil Uses, Dosage, Side Effects, Food Interaction and all others data.
Guamil inhibits protein synthesis by irreversibly binding to the 50s ribosomal subunits thus blocking the transpeptidation or translocation reactions of susceptible organisms resulting in stunted cell growth.
Guamil has the following antibacterial spectrum in vitro: Streptococcus agalactiae, Streptococcus pneumoniae (Pneumococcus), Neisseria meningitides (Meningococcus), Listeria monocytogenes, Mycoplasma pneumoniae, Chlamydia trachomatis, Ureaplasma urealyticum, Legionella pneumophila, Helicobacter (Campylobacter), Gardnerella vaginalis, Bordetella pertussis, Moraxella catarrhalis (Branhamella Catarrhalis), and Haemophilus ducreyi. Guamil is highly concentrated in polymorphonuclear leukocytes and macrophages, achieving intracellular concentrations greater than those outside the cell. Guamil enhances the adhesive and chemotactic functions of these cells which in the presence of infection produce phagocytosis and bacterial lysis. Guamil also possesses intracellular bactericidal activity.

Uses
Guamil is used for the treatment of infections caused by susceptible microorganisms;
Respiratory infections like pneumonia, acute and chronic bronchitis, and bronchopneumonia
ENT infections like tonsillitis, pharyngitis, sinusitis and otitis media.
Skin infections like folliculitis, furuncles, cellulitis, carbuncles, pyoderma, impetigo and infected dermatitis.
Genital infections like urethritis, prostatitis, cervicitis and salpingitis especially if produced by Chlamydia trachomatis.
Guamil, is a macrolide with antibacterial properties similar to erythromycin. It is active against Gram-positive bacteria like staphylococci, streptococci, listeria, corynebacteria; Gram-negative bacteria such as gonococci, Haemophilus influenzae, Haemophilus ducreyi, Legionella, campylobacter, and atypical pathogens like Mycoplasma and Chlamydia. Guamil has been found useful in the treatment of upper and lower respiratory tract infection, otorhinolaryngological, skin, dental and genital infections. It is well tolerated by adults and children.
Guamil is also used to associated treatment for these conditions: Lower Respiratory Tract and Lung Infections, Respiratory Tract Infections (RTI), Skin Infections, Ear, nose, and throat infections
How Guamil works
Guamil prevents bacterial growth by interfering with their protein synthesis. It binds to the 50S subunit of bacterial ribosomes and inhibits the translocation of peptides.
Dosage
Guamil dosage
Adult dose: The usual dose for adults is one 300 mg tablet once daily or one 150 mg tablet twice a day for at least two days after resolution of symptoms, a normal course of therapy is between 5 and 10 days. Guamil is best administered on empty stomach. In severe hepatic impairment the dose is 150 mg once daily.
Pediatric dose: The dose for children is 2.5 to 5 mg/kg body weight twice a day. The following general guidelines can be followed
- 6 to 11 Kg: 25 mg Guamil 12 hourly.
- 12 to 23 Kg: 50 mg Guamil 12 hourly.
- 24 to 40 Kg: 100 mg Guamil 12 hourly.
A normal course of therapy is between 5 and 10 days.
Side Effects
Guamil is well tolerated by patients of all age groups. Less than 4% of treated patients complain of side effects mainly nausea, abdominal pain, diarrhoea and hypersensitivity rash. Other side effects reported include vomiting, dizziness, headache, pruritus, dyspepsia, flatulence, tinnitus, vertigo and constipation. These are in general minor and do not necessitate withdrawal of therapy.
Toxicity
Guamil primarily causes gastrointestinal adverse events, such as diarrhoea, nausea, abdominal pain and vomiting. Less common adverse events include headaches, rashes, abnormal liver function values and alteration in senses of smell and taste.
Precaution
Guamil should not be used in patients with a history of hypersensitivity to the drug. In patients with hepatic diseases the dose of Guamil should not exceed 150 mg twice a day.
Interaction
Guamil does not have any affinity for cytochrome P-450 binding sites and thus is unlikely to produce drug interaction mediated by this enzymatic system. Guamil shows mild interaction with theophylline though this has not been found to produce clinically relevant effects. Alteration in the pharmacokinetics of carbamazepine or warfarin has not been found. Antacids, H2- receptor antagonists and food has no effect on the absorption of Guamil.
Elimination Route
Very rapidly absorbed and diffused into most tissues and phagocytes.
Half Life
12 hours
Pregnancy & Breastfeeding use
The safety of Guamil in pregnancy has not been established. It appears in breast milk in small amounts and dose not produce adverse effects in the breast fed infant.
Contraindication
Guamil should not be administered simultaneously with ergotamine or its derivatives as it may provoke arterial spasm and severe ischaemia.
