Why two NDCs? The FDA registers this code as 63304-497-69 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 63304-0497-69. Same drug, same package — only the format differs.

  • UNII 68401960MK
    Crospovidone is a synthetic polymer made from polyvinylpyrrolidone. It acts as a disintegrant, helping tablets break apart quickly in the stomach so the medicine dissolves and absorbs into the body.
  • UNII 2S7830E561
    Crospovidone is a synthetic polymer derived from povidone. It acts as a disintegrant, helping the tablet or capsule break apart quickly in the stomach so the active ingredient can be absorbed.
  • UNII 70097M6I30

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 63304-497-69, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 63304-0497-69, written without dashes as 63304049769. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 63304-0497-69, the first segment (63304) is the labeler code FDA assigned to Sun Pharmaceutical Industries, Inc.; the middle segment (0497) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (69) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Sun Pharmaceutical Industries, Inc.. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 4 other package presentations of this same product, including 10 tablets (63304-0497-03), 100 tablets (63304-0497-01), 500 tablets (63304-0497-05). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Sun Pharmaceutical Industries, Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

🎯 Indications and Usage 100 words

INDICATIONS AND USAGE Hydrocodone Bitartrate and Acetaminophen Tablets, USP are indicated for the management of moderate to moderately severe pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Limitations of Use Because of the risks of addiction, abuse, and misuse, with opioids, even at recommended doses [see WARNINGS ], reserve Hydrocodone Bitartrate and Acetaminophen Tablets, USP for use in patients for whom alternative treatment options (e.g., non-opioid analgesics): • have not been tolerated, or are not expected to be tolerated, • have not provided adequate analgesia, or are not expected to provide adequate analgesia

⏱️ Dosage and Administration ~2 min read

DOSAGE AND ADMINISTRATION Important Dosage and Administration Instructions Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see WARNINGS ]. Initiate the dosing regimen for each patient individually, taking into account the patient's severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see WARNINGS ]. Follow patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with Hydrocodone Bitartrate and Acetaminophen Tablets, USP and adjust the dosage accordingly [see WARNINGS ].

Initial Dosage Initiating Treatment with Hydrocodone Bitartrate and Acetaminophen Tablets, USP 10 mg/325 mg The usual adult dosage is one tablet every four to six hours as needed for pain. The total daily dosage should not exceed 6 tablets . Conversion from Other Opioids to Hydrocodone Bitartrate and Acetaminophen Tablets There is inter-patient variability in the potency of opioid drugs and opioid formulations.

Therefore, a conservative approach is advised when determining the total daily dosage of Hydrocodone Bitartrate and Acetaminophen Tablets. It is safer to underestimate a patient’s 24-hour Hydrocodone Bitartrate and Acetaminophen Tablets dosage than to overestimate the 24-hour Hydrocodone Bitartrate and Acetaminophen Tablets dosage and manage an adverse reaction due to overdose. Conversion from Hydrocodone Bitartrate and Acetaminophen Tablets to Extended-Release Hydrocodone The relative bioavailability of hydrocodone from Hydrocodone Bitartrate and Acetaminophen Tablets compared to extended-release hydrocodone products is unknown, so conversion to extended-release products must be accompanied by close observation for signs of excessive sedation and respiratory depression.

Titration and Maintenance of Therapy Individually titrate Hydrocodone Bitartrate and Acetaminophen Tablets, USP to a dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving Hydrocodone Bitartrate and Acetaminophen Tablets, USP to assess the maintenance of pain control and the relative incidence of adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse [see WARNINGS ]. Frequent communication is important among the prescriber, other members of the healthcare team, the patient, and the caregiver/family during periods of changing analgesic requirements, including initial titration.

If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the Hydrocodone Bitartrate and Acetaminophen Tablets, USP dosage. If unacceptable opioid-related adverse reactions are observed, consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.

Discontinuation of Hydrocodone Bitartrate and Acetaminophen Tablets, USP When a patient who has been taking Hydrocodone Bitartrate and Acetaminophen Tablets, USP regularly and may be physically dependent no longer requires therapy with Hydrocodone Bitartrate and Acetaminophen Tablets, USP, taper the dose gradually, by 25% to 50% every 2 to 4 days, while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both.

Do not abruptly discontinue Hydrocodone Bitartrate and Acetaminophen Tablets, USP in a physically-dependent patient [see WARNINGS, DRUG ABUSE AND DEPENDENCE ].

⚠️ Warnings ~3 min read

WARNINGS Addiction, Abuse, and Misuse Hydrocodone Bitartrate and Acetaminophen Tablets, USP contains hydrocodone, a Schedule II controlled substance. As an opioid, Hydrocodone Bitartrate and Acetaminophen Tablets exposes users to the risks of addiction, abuse, and misuse [see DRUG ABUSE AND DEPENDENCE ]. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed Hydrocodone Bitartrate and Acetaminophen Tablets.

Addiction can occur at recommended dosages and if the drug is misused or abused. Assess each patient's risk for opioid addiction, abuse, or misuse prior to prescribing Hydrocodone Bitartrate and Acetaminophen Tablets, and monitor all patients receiving Hydrocodone Bitartrate and Acetaminophen Tablets for the development of these behaviors or conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression).

The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as hydrocodone bitartrate and acetaminophen, but use in such patients necessitates intensive counseling about the risks and proper use of hydrocodone bitartrate and acetaminophen along with intensive monitoring for signs of addiction, abuse, and misuse. Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion.

Consider these risks when prescribing or dispensing Hydrocodone Bitartrate and Acetaminophen Tablets. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug [see PRECAUTIONS; Information for Patients ]. Contact local state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product.

Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS) To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to do all of the following: • Complete a REMS-compliant education program offered by an accredited provider of continuing education (CE) or another education program thatincludes all the elements of the FDA Education Blueprint for Health Care Providers Involved in the Management or Support of Patients with Pain. • Discuss the safe use, serious risks, and proper storage and disposal of opioid analgesics with patients and/or their caregivers every time these medicines are prescribed.

The Patient Counseling Guide (PCG) can be obtained at this link: www.fda.gov/OpioidAnalgesicREMSPCG . • Emphasize to patients and their caregivers the importance of reading the Medication Guide that they will receive from their pharmacist every time an opioid analgesic is dispensed to them. • Consider using other tools to improve patient, household, and community safety, such as patient-prescriber agreements that reinforce patient-prescriber responsibilities. To obtain further information on the opioid analgesic REMS and for a list of accredited REMS CME/CE, call 800-503-0784, or log on to www.opioidanalgesicrems.com .

🤒 Adverse Reactions ~2 min read

ADVERSE REACTIONS The following adverse reactions have been identified during post approval use of hydrocodone and acetaminophen tablets and Tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The most frequently reported adverse reactions are light-headedness, dizziness, sedation, nausea and vomiting.

Other adverse reactions include: Central Nervous System - Drowsiness, mental clouding, lethargy, impairment of mental and physical performance, anxiety, fear, dysphoria, psychological dependence, mood changes. Gastrointestinal System- Constipation. Genitourinary System- Ureteral spasm, spasm of vesical sphincters, and urinary retention.

Special Senses- Cases of Hearing impairment or permanent loss have been reported predominantly in patients with chronic overdose. Dermatological- Skin rash, pruritus, Stevens-Johnson syndrome, toxic epidermal necrolysis, allergic reactions Hematological - Thrombocytopenia, agranulocytosis. Serotonin syndrome : Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs. • Adrenal insufficiency : Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. • Anaphylaxis : Anaphylaxis has been reported with ingredients contained in Hydrocodone Bitartrate and Acetaminophen Tablets. • Androgen deficiency : Cases of androgen deficiency have occurred with chronic use of opioids [see CLINICAL PHARMACOLOGY ].

DRUG ABUSE AND DEPENDENCE Controlled Substance Hydrocodone Bitartrate and Acetaminophen Tablets, USP contains hydrocodone, a Schedule II controlled substance. Abuse Hydrocodone Bitartrate and Acetaminophen Tablets, USP contains hydrocodone, a substance with a high potential for abuse similar to other opioids including. Hydrocodone Bitartrate and Acetaminophen Tablets, USP can be abused and is subject to misuse, addiction, and criminal diversion [see WARNINGS ].

All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use. Prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal. “Drug seeking” behavior is very common in persons with substance use disorders.

Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated “loss” of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating healthcare provider(s). “Doctor shopping” (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control.

Abuse and addiction are separate and distinct from physical dependence and tolerance. Healthcare providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true addiction.

🔄 Drug Interactions ~2 min read

Drug Interactions Inhibitors of CYP3A4 and CYP2D6 The concomitant use of Hydrocodone Bitartrate and Acetaminophen Tablets and CYP3A4 inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), and protease inhibitors (e.g., ritonavir), can increase the plasma concentration of hydrocodone from Hydrocodone Bitartrate and Acetaminophen Tablets, resulting in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of Hydrocodone Bitartrate and Acetaminophen Tablets and both CYP3A4 and CYP2D6 inhibitors, particularly when an inhibitor is added after a stable dose of Hydrocodone Bitartrate and Acetaminophen Tablets is achieved [see WARNINGS ] .

After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the hydrocodone plasma concentration will decrease [see CLINICAL PHARMACOLOGY ], resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to Hydrocodone Bitartrate and Acetaminophen Tablets. If concomitant use is necessary, consider dosage reduction of Hydrocodone Bitartrate and Acetaminophen Tablets until stable drug effects are achieved. Follow patients for respiratory depression and sedation at frequent intervals.

If a CYP3A4 inhibitor is discontinued, consider increasing the Hydrocodone Bitartrate and Acetaminophen Tablets dosage until stable drug effects are achieved . Follow for signs or symptoms of opioid withdrawal. Inducers of CYP3A4 The concomitant use of Hydrocodone Bitartrate and Acetaminophen Tablets and CYP3A4 inducers, such as rifampin, carbamazepine, and phenytoin, can decrease the plasma concentration of hydrocodone [see CLINICAL PHARMACOLOGY ], resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to hydrocodone [see WARNINGS ] .

After stopping a CYP3A4 inducer, as the effects of the inducer decline, the hydrocodone plasma concentration will increase [see CLINICAL PHARMACOLOGY ], which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression. If concomitant use is necessary, consider increasing the Hydrocodone Bitartrate and Acetaminophen Tablets dosage until stable drug effects are achieved [see DOSAGE AND ADMINISTRATION ] . Follow the patient for signs and symptoms of opioid withdrawal.

If a CYP3A4 inducer is discontinued, consider Hydrocodone Bitartrate and Acetaminophen Tablets dosage reduction and follow for signs of respiratory depression. Benzodiazepines and Other CNS Depressants Due to additive pharmacologic effect, the concomitant use of benzodiazepines and other CNS depressants, such as benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, and other opioids, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.

Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients closely for signs of respiratory depression and sedation [see WARNINGS ].

Serotonergic Drugs The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), and monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue), has resulted in serotonin syndrome [see PRECAUTIONS; Information for Patients ].

🤰 Pregnancy 145 words

Pregnancy Teratogenic Effects Pregnancy Category C There are no adequate and well-controlled studies in pregnant women. Hydrocodone Bitartrate and Acetaminophen Tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Fetal/Neonatal Adverse Reactions Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth.

Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity, abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see WARNINGS ].

🧓 Geriatric Use ~1 min read

Geriatric Use Elderly patients (aged 65 years or older) may have increased sensitivity to Hydrocodone Bitartrate and Acetaminophen Tablets. In general, use caution when selecting a dosage for an elderly patient, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration.

Titrate the dosage of Hydrocodone Bitartrate and Acetaminophen Tablets slowly in geriatric patients and follow closely for signs of central nervous system and respiratory depression [see WARNINGS ]. Hydrocodone and acetaminophen are known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Hepatic Impairment Patients with hepatic impairment may have higher plasma hydrocodone concentrations than those with normal function. Use a low initial dose of Hydrocodone Bitartrate and Acetaminophen Tablets in patients with hepatic impairment and follow closely for adverse events such as respiratory depression and sedation. Renal Impairment Patients with renal impairment may have higher plasma hydrocodone concentrations than those with normal function.

Use a low initial dose Hydrocodone Bitartrate and Acetaminophen Tablets in patients with renal impairment and follow closely for adverse events such as respiratory depression and sedation.

🆘 Overdosage ~2 min read

OVERDOSAGE Following an acute overdosage, toxicity may result from hydrocodone or acetaminophen. Clinical Presentation Acute overdosage with Hydrocodone Bitartrate and Acetaminophen Tablets can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations.

Acetaminophen Dose-dependent, potentially fatal hepatic necrosis is the most serious adverse effect of acetaminophen overdosage. Renal tubular necrosis, hypoglycemic coma and coagulation defects may also occur. Early symptoms following a potentially hepatotoxic overdose may include: nausea, vomiting, diaphoresis and general malaise.

Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion. Treatment of Overdose Hydrocodone In case of overdose, priorities are the re-establishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated.

Cardiac arrest or arrhythmias will require advanced life-support techniques. The opioid antagonists, naloxone or nalmefene, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to Hydrocodone Bitartrate and Acetaminophen Tablets overdose, administer an opioid antagonist.

Opioid antagonists should not be administered in the absence of clinically significant respiratory or circulatory depression secondary to Hydrocodone Bitartrate and Acetaminophen Tablets overdose. Because the duration of opioid reversal is expected to be less than the duration of action of hydrocodone in Hydrocodone Bitartrate and Acetaminophen Tablets, carefully monitor the patient until spontaneous respiration is reliably reestablished. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the product's prescribing information.

In an individual physically dependent on opioids, administration of the recommended usual dosage of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be initiated with care and by titration with smaller than usual doses of the antagonist.

Acetaminophen Gastric decontamination with activated charcoal should be administered just prior to N-acetylcysteine (NAC) to decrease systemic absorption if acetaminophen ingestion is known or suspected to have occurred within a few hours of presentation. Serum acetaminophen levels should be obtained immediately if the patient presents 4 hours or more after ingestion to assess potential risk of hepatotoxicity; acetaminophen levels drawn less than 4 hours post-ingestion may be misleading. To obtain the best possible outcome, NAC should be administered as soon as possible where impending or evolving liver injury is suspected.

Intravenous NAC may be administered when circumstances preclude oral administration. Vigorous supportive therapy is required in severe intoxication. Procedures to limit the continuing absorption of the drug must be readily performed since the hepatic injury is dose dependent and occurs early in the course of intoxication.

🧬 Clinical Pharmacology ~3 min read

CLINICAL PHARMACOLOGY Mechanism of Action Hydrocodone is full opioid agonist with relative selectivity for the mu-opioid (μ) receptor, although it can interact with other opioid receptors at higher doses. The principal therapeutic action of hydrocodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with hydrocodone.

Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug.

The precise mechanism of the analgesic properties of acetaminophen is not established but is thought to involve central actions. Pharmacodynamics Effects on the Central Nervous System The principal therapeutic action of hydrocodone is analgesia. Hydrocodone produces respiratory depression by direct action on brain stem respiratory centers.

The respiratory depression involves a reduction in the responsiveness of the brain stem respiratory centers to both increases in carbon dioxide tension and electrical stimulation. Hydrocodone causes miosis, even in total darkness. Pinpoint pupils are a sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origins may produce similar findings).

Marked mydriasis rather than miosis may be seen due to hypoxia in overdose situations. Therapeutic doses of acetaminophen have negligible effects on the cardiovascular or respiratory systems; however, toxic doses may cause circulatory failure and rapid, shallow breathing. Effects on the Gastrointestinal Tract and Other Smooth Muscle Hydrocodone causes a reduction in motility associated with an increase in smooth muscle tone in the antrum of the stomach and duodenum.

Digestion of food in the small intestine is delayed and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm, resulting in constipation. Other opioid-induced effects may include a reduction in biliary and pancreatic secretions, spasm of sphincter of Oddi, and transient elevations in serum amylase.

Effects on the Cardiovascular System Hydrocodone produces peripheral vasodilation which may result in orthostatic hypotension or syncope. Manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes, sweating, and/or orthostatic hypotension. Effects on the Endocrine System Opioids inhibit the secretion of adrenocorticotropic hormone (ACTH), cortisol, and luteinizing hormone (LH) in humans [see ADVERSE REACTIONS ].

They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon. Chronic use of opioids may influence the hypothalamic-pituitary-gonadal axis, leading to androgen deficiency that may manifest as symptoms as low libido, impotence, erectile dysfunction, amenorrhea, or infertility. The causal role of opioids in the syndrome of hypogonadism is unknown because the various medical, physical, lifestyle, and psychological stressors that may influence gonadal hormone levels have not been adequately controlled for in studies conducted to date [see ADVERSE REACTIONS ].

Effects on the Immune System Opioids have been shown to have a variety of effects on components of the immune system. The clinical significance of these findings is unknown. Overall, the effects of opioids appear to be modestly immunosuppressive.

Concentration–Efficacy Relationships The minimum effective analgesic concentration will vary widely among patients, especially among patients who have been previously treated with potent agonist opioids. The minimum effective analgesic concentration of hydrocodone for any individual patient may increa…
