The Compliance Pak contains a single 100-mg TROVAN (trovafloxacin mesylate) tablet and one ZITHROMAX (azithromycin for oral suspension) Single-Dose Packet, 1 gram.

The TROVAN/ZITHROMAX Compliance Pak refers to a specific dual treatment for uncomplicated urethral gonorrhea in males and endocervical and rectal gonorrhea in females caused by Neisseria gonorrhoeae and non-gonoccocal urethritis/cervicitis caused by Chlamydia trachomatis.

The data provided in this prescribing information is specific only to these two indications.

For complete information on other available forms of TROVAN and ZITHROMAX as well as their uses, please consult the relevant product prescribing information.



TROVAN Tablets contain trovafloxacin mesylate, a synthetic broad-spectrum antibacterial agent for oral administration. Chemically, trovafloxacin mesylate, a fluoronaphthyridone related to the fluoroquinolone antibacterials, is (1α, 5α, 6α)-7-(6-amino-3-azabicyclo[3.1.0]hex-3-yl)-1-(2,4-difluorophenyl)-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid, monomethanesulfonate. Trovafloxacin mesylate differs from other quinolone derivatives by having a 1,8-naphthyridine nucleus.

The chemical structure is:

ZITHROMAX SINGLE DOSE PACKET contains the active ingredient azithromycin, an azalide, a subclass of macrolide antibiotics, for oral administration. Azithromycin has the chemical name (2R,3S,4R,5R,8R,10R,11R,12S,13S,14R)-13-[(2,6-dideoxy-3-C-methyl-3-O-methyl-α-L-ribo-hexopyranosyl)oxy]-2-ethyl-3,4,10-trihydroxy-3,5,6,8,10,12,14-heptamethyl-11-[[3, 4,6- trideoxy-3-(dimethylamino)-β-D-xylo-hexopyranosyl]oxy]-1-oxa-6-azacyclopentadecan-15-one. Azithromycin is derived from erythromycin; however, it differs chemically from erythromycin in that a methyl-substituted nitrogen atom is incorporated into the lactone ring. Its molecular formula is C38H72N2O12, and its molecular weight is 749.0. Azithromycin has the following structural formula:
