Dox-SL

Product Overview

Doxt-SL is a pharmaceutical formulation combining the active ingredients Doxycycline and Lactic Acid. This dual-action therapy is designed to combat bacterial infections while supporting oral health. Doxycycline, a tetracycline-class antibiotic, exerts its therapeutic effect by inhibiting bacterial protein synthesis, making it effective against a broad spectrum of bacterial pathogens. The lactic acid component functions as a pH modulator, helping maintain optimal oral acidity to inhibit pathogenic bacterial growth and promote a healthy oral microbiome. This synergistic combination provides comprehensive antimicrobial therapy with added oral health benefits.

Therapeutic Indications

Doxt-SL is clinically indicated for:
– Treatment of bacterial infections including respiratory, genitourinary, dermatological, and sexually transmitted infections
– Prophylaxis and treatment of dental infections
– Maintenance of oral health and prevention of oral microbial imbalances

The antibiotic component (doxycycline) demonstrates bactericidal activity by disrupting bacterial protein synthesis, while lactic acid creates an unfavorable environment for pathogenic oral flora through pH modulation.

Administration Guidelines

For optimal therapeutic outcomes:
– Administer orally with 240 mL of water
– Preferred administration timing is 1 hour before or 2 hours after meals
– Strictly adhere to prescribed dosing schedule
– Complete entire prescribed course, even with symptom resolution
– Avoid concomitant administration with:
* Dairy products
* Antacids
* Cation-containing preparations
* Iron supplements

Mechanism of Action

The therapeutic efficacy of Doxt-SL derives from:
1. Doxycycline component:
– Binds to 30S ribosomal subunit
– Inhibits aminoacyl-tRNA binding
– Disrupts bacterial protein synthesis
– Exhibits broad-spectrum activity against Gram-positive, Gram-negative, and atypical pathogens

2. Lactic acid component:
– Modulates oral pH to ~4.5-5.5
– Creates bacteriostatic environment
– Promotes commensal flora
– Inhibits cariogenic bacteria

Dosage Protocol

Dosing parameters are individualized based on:
– Infection type and severity
– Patient demographics (age/weight)
– Renal/hepatic function

Standard regimen:
– Adults: 100-200 mg daily (single or divided doses)
– Duration: Typically 7-14 days (varies by indication)

Critical considerations:
– Maintain consistent dosing intervals
– Never exceed prescribed duration
– Complete full therapeutic course
– Renal dose adjustment required for CrCl <30 mL/min Therapeutic Advantages

Doxt-SL offers multidimensional benefits:
1. Antimicrobial efficacy:
– Broad-spectrum coverage
– Concentration-dependent killing
– Post-antibiotic effect

2. Oral health benefits:
– pH optimization
– Biofilm disruption
– Enamel protection
– Halitosis reduction

3. Clinical advantages:
