Doxycycline is an antibacterial bacteriostatic agent that acts by interfering with the bacterial protein synthesis of species.

Doxycycline is semisynthetic tetracycline derived from Oxytetracycline. It acts on the 30s ribosomal subunit, to which is bound reversibly, blocking the union between the aminoacyl-tRNA (transfer RNA) to the mRNA-ribosome complex, preventing the addition of new amino acids into the growing peptide chain & thus interfering with protein synthesis.

Doxycycline is active against gram positive and gram negative bacteria.

Bromhexine is a benzyl amine with expectorant properties. It is used alone or in combination with antimicrobials for treatment of respiratory diseases.

Bromhexine the volume of the bronchial secrtion, modifies the pattern of mucopolysaccharides produced by the secretory cells, reduces the viscosity of the mucus and increases the tracheobronchial ciliary activity


Each one ml contains:

Doxycycline hyclate…………………………………………. 115.4 mg

(Equivalent to 100 mg Doxycycline base)
