What Is Amoxicillin Trihydrate?

Amoxicillin trihydrate is the pharmaceutical salt form of amoxicillin — the exact chemical form found in the vast majority of amoxicillin capsules, tablets, and oral suspension products on the market. The name "trihydrate" refers to the three water molecules incorporated into the crystalline structure, which improve stability and shelf life. Clinically, amoxicillin trihydrate and amoxicillin base are interchangeable — same drug, same effects, same dosing.

What Does It Treat?

Amoxicillin trihydrate has the same indications as amoxicillin, effective against a broad range of bacterial infections including:

• Strep throat (pharyngitis / tonsillitis)
• Ear infections (otitis media)
• Sinus infections (acute bacterial sinusitis)
• Urinary tract infections (UTIs)
• Community-acquired pneumonia (mild to moderate)
• Skin infections from susceptible gram-positive bacteria
• H. pylori — as part of combination eradication therapy
• Lyme disease — early localized disease
• Dental infections and prophylaxis

How Does It Work?

Amoxicillin trihydrate is converted to free amoxicillin in the body, which then acts as a beta-lactam antibiotic by binding to penicillin-binding proteins (PBPs) on bacterial cell walls. By blocking PBPs, amoxicillin prevents cell wall formation, causing the bacteria to rupture and die. It is bactericidal — actively kills bacteria rather than just slowing their growth.

Dosage Overview

• Adults (mild-moderate infections): 500 mg every 12 hours, or 250 mg every 8 hours
• Adults (severe infections): 875 mg every 12 hours, or 500 mg every 8 hours
• Strep throat: 500 mg twice daily or 1,000 mg once daily for 10 days
• Children: 25–45 mg/kg/day in divided doses (weight-based)

Always complete the full course of antibiotics, even if symptoms improve, to prevent incomplete treatment and antibiotic resistance.
