Dicloxacillin Sodium Absorption

Rapid and incomplete absorption. T max is 1 to 1.5 h. C max is 10 to 17 mcg/mL. Food delays absorption; take on empty stomach.

Dicloxacillin Sodium Distribution

Approximately 98% protein bound, mainly to albumin. Excreted in breast milk and crosses the placenta. Low CSF penetration.

Dicloxacillin Sodium Elimination

Rapidly eliminated, primarily as unchanged drug in the urine. Nonrenal elimination includes hepatic inactivation and excretion in bile. t ½ approximately 0.7 h.

Usage:

Dicloxacillin Sodium is an oral semisynthetic isoxazolyl antistaphylococcal penicillin. Like other antistaphylococcal penicillins, Dicloxacillin Sodium is stable against penicillinase, is active against many of the penicillinase-producing strains of Staphylococcus aureus, and is used mainly in the treatment of infections caused by these organisms. Dicloxacillin Sodium is the most active of the isoxazolyl antistaphylococcal penicillins. Clinical uses of Dicloxacillin Sodium include skin and soft-tissue infections, bone and joint infections, and urinary and respiratory tract infections.

Dicloxacillin Sodium, because of its side chain, resists destruction by beta-lactamases. This makes it useful for treating bacteria that resist penicillin due to the presence of penicillinase. Dicloxacillin Sodium is ineffective, however, against methicillin-resistant S. aureus (MRSA). These organisms appear to resist Dicloxacillin Sodium and related antistaphylococcal penicillins due to the presence of a relatively insensitive PBP, although this mechanism is not fully understood.

Dicloxacillin Sodium is extremely active against most strains of penicillinase-producing Staphylococcus aureus and some strains of Staphylococcus epidermidis. As mentioned above, methicillin-resistant strains of staphylococci are resistant. The antistaphylococcal penicillins are active against group A streptococci and Streptococcus viridans, but the natural penicillins are more potent against streptococci and are preferred. The antistaphylococcal penicillins have limited activity against gram-negative and anaerobic bacteria and are not recommended for treating these infections. Clinicians are advised to consult susceptibility data to determine Dicloxacillin Sodium activity.
