Blephamide (Sulfacetamide and Prednisolone) - Uses, Side effects

Blephamide (Sulfacetamide and prednisolone) is a combination of a steroid and anti-infective medicine that is used to treat inflammatory ocular conditions.

Blephamide (Sulfacetamide and Prednisolone) Uses:

  • Inflammatory ocular conditions:

    • Treatment of
      • steroid-responsive inflammatory ocular conditions (where either a superficial bacterial ocular infection or the risk of bacterial ocular infection exists) of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe;
      • chronic anterior uveitis;
      • corneal injury from chemical, radiation, or thermal burns;
      • penetration of foreign bodies

Blephamide dose in Adults

Blephamide dose in the treatment of Inflammatory ocular conditions:

  • Ointment:

    • Apply about 1/2 an inch ribbon to lower conjunctival sac 3 to 4 times daily and 1 to 2 times at night
  • Solution:

    • Instill 2 drops every 4 hours

Blephamide dose in Childrens

Blephamide dose in the treatment of Inflammatory ocular conditions:

  • Children ≥6 years and Adolescents:

    • Ophthalmic: Refer to adult dosing.

Pregnancy Risk Category: C

  • Animal reproduction studies have not been conducted yet with this combination.
  • The use of systemic sulfonamides during pregnancy may cause kernicterus in the newborn.
  • See individual agents.

Sulfacetamide and prednisolone use during breastfeeding:

  • It is unknown if topical use results in sufficient absorption to produce detectable quantities in breast milk.
  • Use of systemic sulfonamides while breast-feeding may cause kernicterus in the newborn; the amount of systemic absorption following ophthalmic administration is not known.
  • Due to the high potential for serious adverse reactions in the breast-feeding infant, the drug manufacturer recommends a decision to be made whether to discontinue breast-feeding or to discontinue the drug, taking into account the need for treatment to the mother.
  • See individual agents (sulfacetamide and prednisolone)

Contraindications to Blephamide (Sulfacetamide and prednisolone):

  • Hypersensitivity/hyperresponsiveness to sulfacetamide, prednisolone, other sulfonamides or corticosteroids, or any component of the formulation/packaging;
  • viral diseases (including epithelial herpes simplex keratitis [dendritic keratitis], vaccinia, varicella) of the cornea or conjunctiva;
  • fungal diseases of ocular structures;
  • mycobacterial ocular infections

Note:

  • Although the FDA-approved product labeling claims that this is contraindicated with other sulfonamide-containing drug groups, the scientific basis of this statement has been challenged now. See "Warnings/Precautions" for more detail.
  • Canadian labeling: Additional contraindications (not in US labeling):

    • Purulent untreated ocular infections.

Warnings and Precautions

  • Blood dyscrasias:

    • Severe reactions including agranulocytosis,
    • aplastic anemia, and
    • other blood dyscrasias have occurred with sulfonamides as well (regardless of route);
    • fatalities have occurred (rare).
    • Discontinue at the first sign of serious reaction.
  • Dermatologic reactions:

    • Severe reactions including Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported with sulfonamides (regardless of route);
    • fatalities have occurred (rare).
    • Discontinue at the first sign of a rash.
  • Hepatic necrosis:

    • Severe reactions, including fulminant hepatic necrosis, have been reported with sulfonamides (regardless of route);
    • fatalities have occurred (rare).
    • Discontinue at the first sign of serious reaction.
  • Hypersensitivity reactions:

    • Hypersensitivity reactions, skin rash, or other serious reactions may occur;
    • discontinue at the first sign of hypersensitivity reaction.
    • Cross sensitivity among corticosteroids has occurred.
  • Infection:

    • Prolonged use of corticosteroids may raise the incidence of superseded secondary infection, also can mask acute infection (including fungal infections), or prolong or exacerbate viral infections.
    • Corticosteroids should not be used for the treatment of ocular herpes simplex; use extreme caution in patients with a past history of ocular herpes simplex.
    • Fungal infection should be suspected in any patient having persistent corneal ulceration and has received corticosteroids.
  • Ocular effects:

    • Prolonged use of steroids may end in posterior sub-capsular cataract formation and may result in increase intraocular pressure, resulting in ocular hypertension/glaucoma with damage to the optic nerve, causing defects in visual acuity, and fields of vision.
    • Acute anterior uveitis may occur in susceptible patients, primarily black patients.
    • Use with caution in patients with glaucoma (steroids increase intraocular pressure).
    • Perforation may occur with topical steroids in diseases with thin cornea or sclera.
    • Intraocular pressure should be monitored if this product is used >10 days.
  • Sulfonamide ("sulfa") allergy:

    • Traditionally, concerns for cross-reactivity have extended to all compounds containing the sulfonamide structure (SO-NH ).
    • An expanded understanding of allergic mechanisms shows that cross-reactivity between antibiotic sulfonamides and non-antibiotic sulfonamides may not develop, or at the very least this potential is very rare (Brackett 2004; Johnson 2005; Slatore 2004; Tornero 2004).
    • In particular, mechanisms of cross-reaction due to antibody production (anaphylaxis) are least likely to occur with nonantibiotic sulfonamides and antibiotics sulfonamides.
    • A nonantibiotic sulfonamide compound that has an arylamine structure may cross-react with antibiotic sulfonamides is sulfasalazine.
    • T-cell–mediated i.e type IV reactions (eg, maculopapular rash) are less understood and it is impossible to completely exclude this potential based on current insights.
    • In cases where prior reactions were severe (Stevens-Johnson syndrome/TEN), some clinicians prefer to avoid exposure to these classes.
  • Dry eye:

    • Caution is advised in patients with severe dry eye.

Sulfacetamide and prednisolone: Drug Interaction

Risk Factor C (Monitor therapy)

Nonsteroidal Anti-Inflammatory Agents (Ophthalmic)

May enhance the adverse/toxic effect of Corticosteroids (Ophthalmic). Healing of ophthalmic tissue during concomitant administration of ophthalmic products may be delayed.

Ritodrine

Corticosteroids may enhance the adverse/toxic effect of Ritodrine.

Monitoring parameters:

  • Signs and symptoms of improvement after 2 days of therapy;
  • signs and symptoms of secondary infection;
  • intraocular pressure in patients with glaucoma or with prolonged use (≥10 days);
  • periodic exam of lens with prolonged use

How to administer Blephamide (Sulfacetamide and prednisolone)?

  • For topical ophthalmic use only;
  • to avoid contamination, do not touch the container tip to the eyelids or other surfaces while placing drops or ointment in the eyes.
  • Do not apply with silver preparations.
  • Discontinue if symptoms do not improve after 2 days.
  • Not more than 20 mL or 8 gm should be prescribed without proper re-evaluation of the patient.
  • Ointment:

    • Apply into the pocket between the eyeball and lower lid;
    • The patient should be advised to look down before closing the eye.

Solution/Suspension:

  • Tilt head back,
  • instill into the conjunctival sac and close eye(s).
  • Apply light finger pressure on the lacrimal sac for about 1 minute following instillation.
  • Shake the suspension well before using.

Mechanism of action of Blephamide (Sulfacetamide and prednisolone):

  • Sulfacetamide interferes with bacterial growth by inhibiting the bacterial folic acid synthesis of PABA through competitive antagonism ;
  • Prednisolone decreases inflammation by suppression of migration of polymorphonuclear leukocytes and reduction of increased capillary permeability;
  • It also suppresses the immune system by decreasing the activity and volume of the lymphatic system
