AVC - General Information
AVC is a molecule containing the sulfonamide functional group attached to an aniline. [Wikipedia]
Pharmacology of AVC
AVC 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.
AVC for patients
Sulfonamides (sul-FON-a-mides), or sulfa medicines, are used to treat bacterial infections. They work by killing bacteria or preventing their growth.
Vaginal sulfonamides are used to treat bacterial infections. These medicines may also be used for other problems as determined by your doctor.
- Inform you doctor if you have ever had any unusual or allergic reaction to any of the sulfa medicines, furosemide (e.g., Lasix) or thiazide diuretics (water pills), oral antidiabetics (diabetes medicine you take by mouth), or glaucoma medicine you take by mouth (for example, acetazolamide [e.g., Diamox], dichlorphenamide [e.g., Daranide], or methazolamide [e.g., Neptazane]).
- Vaginal sulfonamides are absorbed through the vagina into the bloodstream and appear in the bloodstream of the fetus so if you are pragnent inform you doctor
- Vaginal sulfonamides are absorbed through the vagina into the bloodstream and pass into the breast milk. Use is not recommended in nursing mothers.
- Medicine is only for the use of adults not for children
- Inform your doctor if you have other medical problems.
This medicine is generally safe with other medications, but patient should consult doctor or pharmacist if patient is taking a blood thinner (anticoagulant), cyclosporin, phenytoin, or methotrexate.
Additional information about AVC
AVC Indication: For the treatment of vulvovaginitis caused by Candida albicans.
Mechanism Of Action: AVC 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.
