05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Tetracyclines are bacteriostatic antibiotics active on Gram + and Gram - bacteria, chlamydias, mycoplasma, rickettsiae and amoebas. Tetracyclines inhibit the protein synthesis of bacteria. Their site of action is the bacterial ribosome. In Gram germs, the antibiotic passively diffuses through the hydrophilic channels of the outer cell membrane formed by proteins. Subsequently it is transported, according to an energy-dependent mechanism, through the internal cytoplasmic membrane.
The mechanism of action underlying the penetration of Gram + bacteria is less clear; the involvement of an energy-dependent transport mechanism is certain.
Inside the bacterial cell, the tetracyclines bind to the 30 S subunit of the ribosomes at the level of which they prevent the contact between the aminoacyl-tRNA and the mRNA-ribosome complex, preventing the elongation of the polypeptide chain in formation.
Resistance to tetracyclines develops slowly and is mediated by plasmids.
Sulfamethylthiazole is a sulfonamide antibiotic, bacteriostatic with a broad antibacterial spectrum. In fact, it is active on Gram + and - germs and on Chlamydia trachomatis. Sulfonamides are structural analogues and competitive antagonists of paraminobenzoic acid (PABA) and therefore prevent the normal bacterial use of PABA for the synthesis of folic acid.
05.2 Pharmacokinetic properties
Most tetracyclines are absorbed although not completely from the gastrointestinal tract. Absorption is greater on an empty stomach; it is lower in the more distal segments of the gastrointestinal tract; it is however altered by the concomitant ingestion of milk, aluminum hydroxide gel, calcium salts, magnesium, iron and bismuth subsalicylate.
After oral administration, Oxytetracycline and Tetracycline reach maximum plasma concentrations within 2-4 hours. These drugs have a half-life of 6-12 hours. Maximum plasma concentrations of 2-2.5 mcg / ml are obtained with administration of 250 mg every 6 hours.
Tetracyclines concentrate in the liver and are excreted via the bile in the intestine from where they are partially absorbed. They cross the placenta and enter the fetal circulation and amniotic fluid. Tetracyclines concentrations in the umbilical cord plasma reach 60% and in the fluid. 20% of those present in maternal circulation amniotic Relatively high concentrations are found in breast milk.
The main route of excretion is renal but these antibiotics are also eliminated in the faeces.
Tetracycline and Rolitetracycline, following topical application, do not cause appreciable undesirable effects and are poorly absorbed by the ocular structures.
Tetracyclines have a low acute toxicity: the LD50 in mice is 130 - 180 mg / kg intravenously and 1,500 - 7,000 mg / kg per os.
Sulfonamides are rapidly absorbed from the gastrointestinal tract. An oral dose is absorbed for 70 - 100% and the first traces in the urine are found within 30 minutes of drug intake. Sulfonamides easily cross the placenta and reach the fetal circulation. Absorption after topical administration is null.
05.3 Preclinical safety data
Topical administration of the preparation is followed by poor local and systemic absorption.It has been seen, in fact, that after the application of large quantities of the product on the scarred skin of the rabbit, the plasma does not show any antibacterial activity.
