Ligosan (Doxycycline)

Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing peptide chain elongation. This bacteriostatic effect suppresses the growth of a broad range of oral pathogens and also reduces collagenase activity, helping to limit tissue breakdown in periodontal lesions.

The exact dose and frequency of Ligosan are determined by the prescribing clinician based on the severity of the periodontal condition, the extent of the treated area, and the patient’s overall health. Dosing regimens are individualized and should follow the prescriber’s written instructions.

Ligosan contains doxycycline, which is classified as Pregnancy Category D. It should be used during pregnancy only if the potential benefit outweighs the risk to the fetus. Doxycycline is excreted in breast milk, so caution is advised for nursing mothers, and alternative therapy may be considered.

To request Ligosan, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will ask for trade or institutional credentials. The sales team then replies with pricing, availability, shipping details (including any cold‑chain requirements) and the necessary import documentation.

Ligosan delivers doxycycline directly to the periodontal pocket, providing high local concentrations with limited systemic exposure. Compared with systemic doxycycline or other oral antibiotics, this local delivery can achieve better site‑specific efficacy, reduce systemic side‑effects, and improve patient compliance when used as an adjunct to scaling and root planing.

Ligosan should be stored at ambient temperature, preferably below 25 °C. Keep the product in its original packaging, protect it from moisture and direct light, and ensure the container is tightly closed when not in use to maintain stability.

Ligosan is applied topically by a dental professional directly into the periodontal pocket or gingival sulcus after mechanical cleaning. The clinician follows aseptic technique, inserts the appropriate amount of the formulation, and may use a carrier device to retain the medication at the site for the prescribed duration.

Serious risks include severe allergic reactions such as anaphylaxis, Stevens‑Johnson syndrome or toxic epidermal necrolysis, hepatic toxicity, intracranial hypertension, and Clostridioides difficile‑associated colitis. Patients should be instructed to seek immediate medical attention if they experience rash, fever, jaundice, severe headache, visual changes, or persistent diarrhea.

Ligosan should not be used in patients with known hypersensitivity to doxycycline or other tetracyclines, in children younger than eight years due to the risk of permanent tooth discoloration, and in pregnant women unless the potential benefit justifies the risk. Caution is also advised for patients with severe renal impairment or those taking interacting medications listed under major interactions.
