Doxycycline Hyclate BP

Doxycycline Hyclate BP is a broad-spectrum, semisynthetic tetracycline-class antibiotic available as the hemihydrate salt form of doxycycline. It is widely used in pharmaceutical formulations due to its high bioavailability, broad antibacterial activity, and favorable pharmacokinetic profile. The compound exhibits bacteriostatic action by inhibiting protein synthesis in susceptible bacteria, making it effective against a wide range of Gram-positive and Gram-negative organisms as well as atypical pathogens. It is typically supplied as a fine, white to off-white crystalline powder soluble in water and suitable for oral and parenteral dosage forms.
