Description
Overview of the medicine
Albutrim 200 mg Suspension is an antibacterial medication containing a combination of sulfamethoxazole and trimethoprim. It is used to treat various bacterial infections, particularly those affecting the respiratory, urinary, and gastrointestinal tracts.
Uses & Indications
Dosage
Adults
For specific indications, 20 mL (4 teaspoonfuls) of suspension every 12 hours, though tablet forms are usually preferred for adults. (Standard adult dose typically: Sulfamethoxazole 800 mg and Trimethoprim 160 mg every 12 hours).
Elderly
Dose adjustments may be necessary due to potential age-related decrease in renal function.
Children
Children (6 weeks to 5 months): 2.5 mL every 12 hours; (6 months to 5 years): 5 mL every 12 hours; (6 to 12 years): 10 mL every 12 hours. Dosage should be based on trimethoprim component, 6-12 mg/kg/day in two divided doses, not exceeding adult dosage.
Renal_impairment
Dosage reduction is required for patients with creatinine clearance < 30 mL/min. Not recommended if creatinine clearance < 15 mL/min.
How to Take
For oral administration. Shake well before use. May be taken with or without food, but taking with food can minimize gastrointestinal upset. Drink plenty of fluids to prevent crystalluria.
Mechanism of Action
Sulfamethoxazole inhibits bacterial dihydrofolic acid synthesis by competing with para-aminobenzoic acid (PABA). Trimethoprim inhibits bacterial dihydrofolate reductase, preventing the reduction of dihydrofolate to tetrahydrofolate. This sequential blockade of folic acid synthesis leads to a synergistic antibacterial effect.
Pharmacokinetics
Onset
Antibacterial effect typically observed within 1 to 4 hours.
Excretion
Excreted mainly by the kidneys through glomerular filtration and tubular secretion.
Half life
Trimethoprim: 8-10 hours; Sulfamethoxazole: 10-12 hours.
Absorption
Rapid and almost complete absorption from the gastrointestinal tract after oral administration.
Metabolism
Primarily hepatic metabolism (sulfamethoxazole is N4-acetylated, trimethoprim undergoes oxidation).
Side Effects
Contraindications
- •Hypersensitivity to sulfamethoxazole, trimethoprim, or any component
- •Megaloblastic anemia due to folate deficiency
- •Severe hepatic or renal impairment
- •Porphyria
- •Infants less than 6 weeks of age
- •Pregnancy (late term) and lactation (due to risk of kernicterus in neonates)
Drug Interactions
Warfarin
May increase anticoagulant effect, requiring close INR monitoring.
Phenytoin
May increase phenytoin levels.
Methotrexate
May increase methotrexate levels and toxicity (e.g., bone marrow suppression), especially in elderly.
Diuretics (Thiazide/Loop)
Increased risk of thrombocytopenia with purpura, especially in elderly.
Storage
Store below 30°C. Protect from light and moisture. Do not freeze.
Overdose
Symptoms of acute overdose include nausea, vomiting, diarrhea, dizziness, headache, mental depression, and confusion. Chronic overdose can lead to bone marrow depression (e.g., thrombocytopenia, leukopenia, megaloblastic anemia). Treatment involves gastric lavage or emesis, forced diuresis, and acidification of urine. Leucovorin may be administered to counteract folate deficiency effects.
Pregnancy & Lactation
Category D for pregnancy (risk of neural tube defects in early pregnancy; risk of kernicterus in late pregnancy). Avoid in late pregnancy and during breastfeeding due to the risk of kernicterus in neonates. Use only if potential benefit justifies the potential risk to the fetus or infant.
