Who AM I? Flashcards
I penetrate the cell wall of susceptible bacteria. I bind irreversibly to 30S and 50S ribosomal subunits, intracellular structures that synthesize proteins. As a result, the bacteria cell membrane becomes defective and cannot synthesize the proteins necessary for its growth and replication.
Gentamicin (Aminoglycoside)
I am a bacteriacidal agent that causes cell death. I interfere with the enzymes that are required for synthesis of bacterial DNA and therefore are necessary for growth and replication.
You can’t give me to children <18, or with dairy, or with pregnant women.
Ciproflaxicin
I enter the microbial cell and reversibly bind to the 50S subunits of ribosomes, thereby inhibiting microbial protein synthesis and leading to cell death. I have both bacteriacidal and bacteriostatic activity against susceptible bacteria.
Erythromycin
I treat nausea and vomiting. I block dopamine from receptor sites in the brain and in the chemotherapy trigger zone. I antagonize D2 receptors in the area postrema of the midbrain, thereby decreasing effects of dopamine in the brain. I also possess M1 Muscarinic and H1 Histamine blocking effects.
Promethazine
I relieve nausea and vomiting by blocking the action of acetylcholine in the brain.
Hydroxyzine.
I antagonize serotonin receptors, preventing their activation by the effects of emetogenic drugs
Ondansteron
I work by slowing perstalsis of the smooth muscle in the intestine.
Diphenoxylate with atropine.
I inhibit bacterial cell wall synthesis by binding to one or more penicillin binding proteins. I am more effective at treating gram positive bacteria, but I am occasionally used for gram negative. I also treat infective endocarditis.
Ampicillin
I inhibit the third and last step of bacterial cell wall synthesis by binding to one or more penicillin binding proteins. I am often used as a prophylaxis involving surgical procedures
Cefazolin
I inhibit bacterial cell wall synthesis by binding with penicillin binding proteins. I am given IM/IV, at a max dose of 4 grams per day. I am considered a broad spectrum antibiotic.
Impenem-Cilastin
I inhibit bacterial cell wall synthesis by binding with penicillin binding proteins. I can be given to patients with a known penicillin allergy because of my structure.
Aztreonam
I act as an antimetabolite of PABA which micro-organisms need to produce folic acid. Folic acid is necessary for the production of bacterial intracellular proteins. I enter into the reaction instead of PABA, and compete for the enzyme involved and cause formation of nonfunctional derivatives of folic acid. I halt multiplication of new bacteria, but have no effect on exisiting ones.
TMP-SMZ
I penetrate microbial cells by using passive diffusion and an active transport system. I bind to the 30S ribosomes and I inhibit microbial protein synthesis.
Tetracycline.
I am given to patients with acne. I supress the growth of propionbacterium acnes with sebaceous follicles by reducing the free fatty acid content in the sebum
Tetracycline.
I inhibit sodium and chloride reabsorption in the ascending loop of henle, where absorption of most filtered drugs takes place.
Furosemide
