1. What BRUMETON COLLOIDAL is and what it is used for
BRUMETON COLLOIDAL is a combination of two active substances: betamethasone and sulfacetamide.
Betamethasone belongs to a group of medicines called corticosteroids, which reduce allergy symptoms and relieve inflammation. Sulfacetamide belongs to a group of medicines called antimicrobials, which slow down or stop the growth of bacteria.
BRUMETON COLLOIDAL is indicated for:
- the prevention and treatment of eye disorders, particularly in cases of:
- superficial ocular infections caused by bacteria sensitive to sulfacetamide, for example: Staphylococcus, Streptococcus, Pneumococcus, Hemophilus influenzae, Moraxella lacunata (Morax-Axenfeld diplobacillus), Klebsiella pneumoniae (Friedländer's bacillus), Escherichia coli and Aerobacter aerogenes;
- allergic and inflammatory diseases of the anterior segment of the eye, especially when there is concern about possible infectious complications, such as in inflammations of the conjunctiva (acute, chronic, allergic and/or phlyctenular conjunctivitis, etc.), eyelids (acute, chronic and allergic blepharitis), cornea (interstitial keratitis, phlyctenular keratoconjunctivitis), sclera (scleritis and episcleritis), iris (acute, chronic and traumatic iritis), and iris and ciliary body (iridocyclitis);
- the treatment of ear disorders such as:
- inflammatory conditions (external and middle otitis);
- inflammatory states of the external part of the ear (external auditory canal), particularly those caused by bacteria, for example furunculosis, eczema and dermatitis.
