Abstract

The present invention is a solid dosage form of a doxycycline metal complex. The present invention also includes a process for making a doxycycline metal complex in a solid dosage form. The process comprises the steps of (i) providing an aqueous solution of doxycycline or a physiologically acceptable salt thereof; (ii) admixing a metal salt with the aqueous solution; (iii) admixing a base to increase the pH of the aqueous solution, thereby forming a suspension of doxycycline metal; and (iv) drying the suspension, thereby forming a dry granulation of doxycycline metal complex.
