Pharmacodynamics

Benatex is a local contraceptive drug. It has a spermicidal effect, in addition, it has antiseptic, antifungal, antiprotozoal properties, inactivates the Herpes simplex virus.
Benzalkonium chloride is active against gram-positive (including Staphylococcus spp., Streptococcus spp.), Gram-negative (including Proteus spp., Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp., Neisseria gonorrhoeae) and anaerobic bacteria.
Benatex is also active against bacterial strains that exhibit resistance to antibiotics and other chemotherapeutic drugs; inhibits hyaluronidase and plasmacoagulase of staphylococci.
The spermicidal effect of benzalkonium chloride is based on the ability to damage the membranes of spermatozoa (at the beginning of the flagella, later on the head). This leads to the impossibility of fertilization of the egg with a damaged sperm. After the introduction of the gel, suppository or tablet, the effect develops after 3, 5 and 8-10 minutes, respectively.
