Farmiserina - General Information
Antibiotic substance produced by Streptomyces garyphalus. [PubChem]
Pharmacology of Farmiserina
Farmiserina, a broad-spectrum antibiotic, may be bactericidal or bacteriostatic, depending on its concentration at the site of infection and the susceptibility of the organism. Farmiserina works by blocking the formation of these peptidoglycans. By doing this the walls of the bacteria become weak and it results in the death of the bacteria
Farmiserina for patients
Take this by mouth as directed usually every 12 hours for the first two weeks. This medication works best when the amount of medicine in your body is kept at a constant level. Do this by taking the medication at evenly spaced intervals throughout the day and night. Continue using this for the full time prescribed. It may be necessary to continue therapy for tuberculosis for several months to one year or more. Stopping the medication too early may result in ineffective treatment.
May interact with wthionamide (Trecator-SC) and isoniazid (Nydrazid).
Additional information about Farmiserina
Farmiserina Indication: Used in combination with up to 5 other drugs as a treatment for Mycobacterium avium complex (MAC) and is also used to treat tuberculosis (TB).
Mechanism Of Action: Farmiserina is an analog of the amino acid D-alanine. It interferes with an early step in bacterial cell wall synthesis in the cytoplasm by competitive inhibition of two enzymes, L-alanine racemase, which forms D-alanine from L-alanine, and D-alanylalanine synthetase, which incorporates D-alanine into the pentapeptide necessary for peptidoglycan formation and bacterial cell wall synthesis.
