Megatrim Suspension is a widely used oral antibiotic formulation containing a fixed-dose combination of Sulphamethoxazole (200 mg) and Trimethoprim (40 mg) per 5 ml. This combination is commonly known as co-trimoxazole and is effective against a broad range of bacterial infections in both children and adults. Megatrim Suspension is especially suitable for pediatric patients due to its liquid formulation, which allows accurate dose adjustment and easy administration.

Composition

• Sulphamethoxazole 200 mg

• Trimethoprim 40 mg

• Per 5 ml oral suspension

Therapeutic Class

• Combination antibacterial (Sulfonamide + Folate synthesis inhibitor)

Mechanism of Action

Megatrim Suspension works by inhibiting two consecutive steps in the bacterial folic acid synthesis pathway. Sulphamethoxazole blocks the incorporation of para-aminobenzoic acid into dihydrofolic acid, while Trimethoprim inhibits the reduction of dihydrofolic acid to tetrahydrofolic acid. This dual mechanism results in a synergistic bactericidal effect, effectively stopping bacterial growth and replication.

Indications

Megatrim Suspension is indicated for the treatment of infections caused by susceptible organisms, including:

• Respiratory tract infections such as bronchitis and pneumonia

• Urinary tract infections

• Gastrointestinal infections including traveler’s diarrhea

• Ear infections (otitis media)

• Skin and soft tissue infections

• Certain types of bacterial dysentery

• Pneumocystis jirovecii pneumonia (as per physician guidance)

Dosage and Administration

The dosage of Megatrim Suspension depends on the patient’s age, body weight, severity of infection, and renal function. It should be taken as prescribed by a registered medical practitioner. The suspension should be shaken well before use to ensure uniform distribution of the active ingredients. Completing the full course of therapy is essential to prevent antibiotic resistance.

Use in Children

Megatrim Suspension is commonly prescribed in pediatric practice due to its palatable liquid form and reliable efficacy. Accurate measurement using a proper dosing spoon or cup is recommended.

Precautions and Warnings

• Use with caution in patients with liver or kidney impairment

• Not recommended in patients with known hypersensitivity to sulfonamides or trimethoprim

• Adequate hydration should be maintained during therapy

• Long-term use may require monitoring of blood counts
