DESCRIPTION:

The structural formula of doxycycline hyclate is:

with a molecular formula of (C22H24N2O8.HCI)2.C2H6O.H2O and a molecular weight of 1025.89. The chemical designation for doxycycline is 4-(dimethylamino)-1, 4, 4a, 5, 5a, 6, 11, 12a-octahydro-3, 5, 10, 12, 12a-pentahydroxy-6 -methyl-1, 11-dioxo-2-naphthacenecarboxamide monohydrochloride, compound with ethyl alcohol (2:1), monohydrate.

Doxycycline hyclate is a yellow to light-yellow crystalline powder which is soluble in water.

Each tablet for oral administration contains 23mg doxycycline hyclate equivalent to 20 mg of doxycycline. In addition, each tablet contains the following inactive ingredients: anhydrous lactose, carnauba wax, croscarmellose sodium, hypromellose, magnesum stearate, microcrystalline cellulose, poldextrose, polyethylene glycol, titanium dioxide, and triacetin.

CLINICAL PHARMACOLOGY:

After oral administration, doxycycline hyclate is rapidly and nearly completely absorbed from the gastrointestinal tract. Doxycycline is eliminated with a half-life of approximately 18 hours by renal and fecal excretion of unchanged drug.

Mechanism of Action:

Doxycycline has been shown to inhibit collagenase activity in vitro. 1 Additional studies have shown that doxycycline reduces the elevated collagenase activity in the gingival crevicular fluid of patients with adult periodontitis.23 The clinical significance of these findings is not known.

Microbiology:

Doxycycline is a member of the tetracycline class of antibiotics. The dosage of doxycycline achieved with this product during administration is well below the concentration required to inhibit microorganisms commonly associated with adult periodontitis. Clinical studies with this product demonstrated no effect on total anaerobic and facultative bacteria in plaque samples from patients administered this dose regi...
