(Hydrocodone Bitartrate and Acetaminophen)
Overview of Vicodin
Vicodin, also known as acetaminophen and hydrocodone is part of the opioid pain relievers. An opioid is sometimes called a narcotic. The chemical formula is C18H21NO3. With the combination of acetaminophen and hydrocodone, the acetaminophen increases the effects of hydrocodone due to its small potency.
For medical uses, vicodin is used to treat severe pain. The tablet is produced and marketed under the trade names Vicodin, Vicodin ES, Vicodin HP, Anexsia, Anolor DH5, Bancap HC, Zydone, Dolacet, Lorcet, Lortab, as well as generic brands. Researchers have said that hydrocodone is stronger than codeine but only one-tenth as potent as morphine at binding to receptors.
It is roughly half as potent as morphine in analgesic properties. But, some studies have shown hydrocodone to be anywhere from half as potent to oxycodone (1.5× the potency of morphine) to only 66.6~% the potency of oxycodone.
Vicodin (5mg, 7.5mg, 10mg/300mg)
Each Vicodin tablet has 300 mg of acetaminophen and comes in three different dosage levels of hydrocodone-5 mg, 7.5 mg and 10 mg. Depending on the patient’s needs, Vicodin is usually prescribed within the range of 300mg to 750mg. It is generally prescribed for one tablet taken every 4 to 6 hours, though addicts may take much higher doses.
Vicodin previously was manufactured with higher dosages of acetaminophen (up to 750mg per pill). However, in March 2014, the FDA announced that all manufacturers cease marketing products with more than 325mg of acetaminophen. This is due to the increased risk of liver damage and accidental acetaminophen overdose when taking acetaminophen daily. Previous formulations included 500 to 750 mg of acetaminophen per pill.
