Butalbital and Acetaminophen Tablets are indicated for the relief of the symptom complex of tension (or muscle contraction) headache.

Evidence supporting the efficacy and safety of this combination product in the treatment of multiple recurrent headaches is unavailable. Caution in this regard is required because butalbital is habit-forming and potentially abusable.

Contraindications

This product is contraindicated under the following conditions:

• Hypersensitivity or intolerance to any component of this product.
• Patients with porphyria.

Warnings

Butalbital is habit-forming and potentially abusable. Consequently, the extended use of this product is not recommended.

Precautions

General

Butalbital and Acetaminophen Tablets should be prescribed with caution in certain special-risk patients, such as the elderly or debilitated, and those with severe impairment of renal or hepatic function, or acute abdominal conditions.

This combination drug product is intended as a treatment for tension headache.

It consists of a fixed combination of Butalbital and Acetaminophen. The role each component plays in the relief of the complex of symptoms known as tension headache is incompletely understood.

Pharmacokinetics

The behavior of the individual components is described below.

Butalbital: Butalbital is well absorbed from the gastrointestinal tract and is expected to distribute to most tissues in the body. Barbiturates in general may appear in breast milk and readily cross the placental barrier. They are bound to plasma and tissue proteins to a varying degree and binding increases directly as a function of lipid solubility.

Elimination of butalbital is primarily via the kidney (59% to 88% of the dose) as unchanged drug or metabolites. The plasma half-life is about 35 hours. Urinary excretion products include parent drug (about 3.6% of the dose), 5-isobutyl-5-(2,3-dihydroxypropyl) barbituric acid (about 24% of the dose), 5-allyl-5(3-hydroxy-2-methyl-l-propyl) barbituric acid (about 4.8% of the dose), products with the barbituric acid ring hydrolyzed with excretion of urea (about 14% of the dose), as well as unidentified materials. Of the material excreted in the urine, 32% is conjugated.

The in vitro plasma protein binding of butalbital is 45% over the concentration range of 0.5 to 20 mcg/mL. This falls within the range of plasma protein binding (20% to 45%) reported with other barbiturates such as phenobarbital, pentobarbital, and secobarbital sodium. The plasma-to-blood concentration ratio was almost unity indicating that there is no preferential; distribution of butalbital into either plasma or blood cells (See OVERDOSAGE for toxicity information.).

Acetaminophen: Acetaminophen is rapidly absorbed from the gastrointestinal tract and is distributed throughout most body tissues. The plasma half-life is 1.25 to 3 hours, but may be increased by liver damage and following overdosage. Elimination of acetaminophen is principally by liver metabolism (conjugation) and subsequent renal excretion of metabolites. Approximately 85% of an oral dose appears in the urine within 24 hours of administration, most as the glucuronide conjugate, with small amounts of other conjugates and unchanged drug (See OVERDOSAGE for toxicity information.).

Butalbital/APAP/Caffeine Oral Uses

This combination medication is used to treat tension headaches. Acetaminophen helps to decrease the pain from the headache. Caffeine helps increase the effects of acetaminophen. Butalbital is a sedative that helps to decrease anxiety and cause sleepiness and relaxation.

How To Use Butalbital/APAP/Caffeine Oral

Take this medication by mouth with or without food, usually every 4 hours as needed or as directed by your doctor.

The dosage is based on your medical condition and response to therapy. This medication works best if it is used as the first signs of a headache occur. If you wait until the headache has worsened, the medication may not work as well.

This medication may cause dependence, especially if it has been used regularly for an extended time or if it has been used in high doses. In such cases, withdrawal reactions (e.g., nausea/vomiting, mental/mood changes, seizures) may occur if you suddenly stop this drug. To prevent withdrawal reactions when stopping extended, regular treatment with this drug, gradually reduce the dosage as directed. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.

Though very unlikely, abnormal drug-seeking behavior (addiction) is possible with this medication. To lessen the risk of becoming addicted, do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.

This medication contains acetaminophen. Do not take more acetaminophen than recommended. (See also Side Effects, Drug Interactions sections.)

Inform your doctor if you notice increased use of this medication, a worsening of headaches, an increase in the number of headaches, the medication not working as well, or use of this medication for more than 2 headache episodes a week. Your doctor may need to change your medication and/or add a separate medication to prevent the headaches.
