Description
Rifamycins are a class of antibiotics that are derived from the bacterium Amycolatopsis rifamycinica. They are known for their broad-spectrum activity against a wide range of gram-positive and some gram-negative bacteria. Rifocin, in particular, is effective against infections caused by microorganisms that are sensitive to the rifamycin compound.
Rifocin Im Injection Composition
Each 3 mL ampule of Rifocin contains the following active and inactive ingredients:
Active Ingredient:
- Rifamisin SV: 250 mg
Inactive Ingredients:
- Lidocain hidroklorür monohidrat: 10 mg
- Ascorbic acid
- Disodium EDTA
- Polyvinylpyrrolidone K17
- Water for injection
- Sodium bicarbonate
- Sodium hydroxide
- Potassium metabisulfite
The combination of rifamycin SV and lidocaine hydrochloride monohydrate in Rifocin provides both the antibiotic and local anesthetic properties, making it suitable for intramuscular administration.
Indications
Rifocin is primarily prescribed for the following conditions:
1. Infections caused by gram-positive microorganisms that are sensitive to it, especially when other antibiotic treatments have failed. This includes a wide range of bacterial infections, such as those caused by Staphylococcus, Streptococcus, and Enterococcus species.
2. Skin and soft tissue infections, such as:
- Furunculosis (boils)
- Pyoderma (pus-filled skin infection)
- Abscesses
- Lymphadenitis (lymph node inflammation)
3. Osteomyelitis (bone inflammation)
4. Bronchopulmonary infections caused by gram-positive microorganisms, including staphylococcal bacteremia (proliferation of Staphylococcus bacteria in the blood).
5. Bacterial infections related to the bile ducts, including those caused by gram-negative microorganisms or mixed flora.
Rifocin is particularly useful in situations where other antibiotic treatments have been unsuccessful or when the infection is caused by microorganisms that are resistant to more commonly used antibiotics.
