Flexyx drugs: Haptocil

Haptocil - General Information:

Antibacterial, potentially toxic, used to treat certain skin diseases. [PubChem]

Pharmacology:

Haptocil is a sulfonamide antibiotic. The sulfonamides are synthetic bacteriostatic antibiotics with a wide spectrum against most gram-positive and many gram-negative organisms. However, many strains of an individual species may be resistant. Sulfonamides inhibit multiplication of bacteria by acting as competitive inhibitors of p-aminobenzoic acid in the folic acid metabolism cycle. Bacterial sensitivity is the same for the various sulfonamides, and resistance to one sulfonamide indicates resistance to all. Most sulfonamides are readily absorbed orally. However, parenteral administration is difficult, since the soluble sulfonamide salts are highly alkaline and irritating to the tissues. The sulfonamides are widely distributed throughout all tissues. High levels are achieved in pleural, peritoneal, synovial, and ocular fluids. Although these drugs are no longer used to treat meningitis, CSF levels are high in meningeal infections. Their antibacterial action is inhibited by pus.

Haptocil Contraindications

Contraindications

Sulfapyridine should not be used if there is an allergy to sulfapyridine, other sulfonamides, furosemide, thiazide diuretics, sulfonylureas, or carbonic anhydrase inhibitors.

Sulfapyridine can cause agranulocytosis, aplastic anemia, or other blood dyscrasias.

Sulfapyridine should not be used when there is other medical problems, especially blood dyscrasias, G6PD deficiency, hepatic function impairment, porphyria, and renal function impairment

Haptocil Indication: For the treatment of dermatitis herpetiformis, benign mucous membrane pemphigoid and pyoderma gangrenosum
Mechanism Of Action: Haptocil is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA), a substrate of the enzyme dihydropteroate synthetase. The inhibited reaction is necessary in these organisms for the synthesis of folic acid.
