Probenecid 100 mg/ml Oral Suspension

The Probenecid 100 mg/ml Oral Suspension is a specially compounded liquid formulation designed to facilitate ease of administration for patients who may have difficulty swallowing solid dosage forms. Unlike the described solid dosage forms enclosed in gelatin or vegetarian shells, this oral suspension provides an alternative for precise dosing in a liquid form. Probenecid is commonly used in the treatment of chronic gout and gouty arthritis, conditions characterized by the accumulation of uric acid crystals in the joints, leading to pain and inflammation. Additionally, Probenecid is used to prolong the efficacy of certain antibiotics by delaying their excretion from the body. This oral suspension ensures that patients with these disease states receive the accurate dosage of Probenecid in a form that is easy to ingest.

Formula Information

A small arrow pointing down

Probenecid is a medication traditionally used to treat gout and hyperuricemia by inhibiting the renal tubular reabsorption of urate, thus increasing the excretion of uric acid in the urine. It is also used to prolong the half-life of certain antibiotics, such as penicillin, by reducing their renal excretion. The formulation of Probenecid 100 mg/ml Oral Suspension encapsulated in either gelatin or vegetarian shells offers a solid dosage form that is designed to enhance patient compliance through ease of swallowing and precise dosing. This is particularly beneficial for patients who may have difficulty swallowing tablets or who require a dosage that is not readily available in a standard tablet form.

The encapsulated oral suspension allows for a liquid medication to be delivered in a solid form, which can be advantageous for maintaining the stability of the active ingredient and ensuring consistent dosing. The shells dissolve after ingestion, releasing the suspension for absorption. This formulation is carefully compounded to ensure homogeneity, meaning each capsule contains the exact amount of Probenecid required for effective treatment. It is important for prescribers to note that the bioavailability of Probenecid in this form should be considered when determining the dosing regimen for their patients, as it may differ from that of traditional tablet forms.

For patients, it is crucial to adhere to the prescribed dosing schedule and to be aware of potential interactions with other medications, particularly those that are also excreted by the kidneys. Probenecid may affect the excretion rates of other drugs, which could lead to increased levels of these medications in the blood and a higher risk of side effects. Patients should also be advised to maintain adequate hydration to facilitate the urinary excretion of uric acid and to report any adverse effects or concerns to their healthcare provider promptly.

For prescribers, it is essential to consider the patient's overall medication regimen and any comorbid conditions that may influence the use of Probenecid. Regular monitoring of uric acid levels and renal function tests are recommended to ensure the effectiveness of the treatment and to adjust the dosage as necessary. Additionally, prescribers should be aware of the signs and symptoms of gout flare-ups and provide appropriate management strategies for their patients.

Drug Interactions

A small arrow pointing down

Probenecid is a medication commonly used to treat gout and hyperuricemia by increasing the excretion of uric acid in the urine. It is also used to prolong the half-life of certain antibiotics, such as penicillin. When considering the use of Probenecid 100 mg/ml Oral Suspension, it is important to be aware of potential drug interactions that may affect the efficacy of the treatment or cause adverse effects.

One significant interaction is with salicylates, such as aspirin. High doses of salicylates can decrease the uricosuric effect of probenecid, which may reduce its effectiveness in treating gout. Patients should avoid taking high doses of salicylates or use an alternative analgesic if they are being treated with probenecid. Conversely, probenecid can increase the plasma concentration of salicylates, which may lead to salicylate toxicity, especially in patients with renal impairment.

Probenecid can also interact with other medications that are excreted by the kidneys. It competes with the renal tubular secretion of many drugs, which can lead to increased plasma concentrations and potential toxicity of these medications. Examples include methotrexate, indomethacin, ketoprofen, naproxen, and other nonsteroidal anti-inflammatory drugs (NSAIDs), as well as some antibiotics like cephalosporins and penicillins. Patients should inform their healthcare provider of all medications they are taking to assess for potential interactions.

Additionally, probenecid may interact with oral hypoglycemic agents, such as sulfonylureas, leading to prolonged hypoglycemic effects. Diabetic patients taking these medications should be closely monitored for signs of hypoglycemia when starting or adjusting the dose of probenecid.

Patients receiving probenecid with antineoplastic or radiation therapy may have an increased risk of bone marrow suppression. It is crucial to monitor blood counts in these patients to prevent potential complications.

Probenecid may also affect the excretion of other drugs such as lorazepam, rifampin, and zidovudine, potentially altering their effectiveness or increasing the risk of adverse effects. It is important to monitor patients for signs of toxicity or therapeutic failure when these drugs are used concurrently with probenecid.

Lastly, probenecid can interfere with the renal excretion of loop diuretics, thiazide diuretics, and beta-blockers, potentially diminishing their diuretic and antihypertensive effects. Patients on these medications may require dosage adjustments or close monitoring of their blood pressure and renal function.

It is essential for patients and prescribers to be aware of these and other potential drug interactions when using Probenecid 100 mg/ml Oral Suspension. Always consult with a healthcare provider before starting, stopping, or changing the dose of any medication. If you have any questions or concerns regarding drug interactions with probenecid, please reach out to us at Bayview Pharmacy for further assistance.

How Does it Work

A small arrow pointing down

Probenecid is a medication that is primarily used to treat gout and hyperuricemia. It works by inhibiting the reabsorption of uric acid in the kidneys, which increases the excretion of uric acid in the urine. This helps to reduce the concentration of uric acid in the blood, thereby preventing the formation of uric acid crystals that can accumulate in the joints and cause the pain and inflammation characteristic of gout. Probenecid also has the added benefit of increasing the concentration of certain antibiotics in the blood, making it useful in prolonging their effects when used concurrently.

The formulation of Probenecid as a 100 mg/ml oral suspension encapsulated in solid dosage forms, such as two-piece gelatin or vegetarian capsules, offers several advantages. The encapsulation of the liquid suspension allows for precise dosing, as each capsule contains a measured amount of the medication. This form is also easier to swallow compared to tablets, which can be beneficial for patients who have difficulty swallowing solid pills. Additionally, the liquid-filled capsules may offer faster release and absorption of the medication compared to traditional solid tablets, potentially leading to quicker onset of action.

When using this formulation, it is important for patients to understand that the medication must be taken consistently and as prescribed to maintain effective control of uric acid levels. It is also essential to stay well-hydrated to facilitate the excretion of uric acid. Prescribers should monitor their patients' uric acid levels and kidney function to ensure the medication is working effectively and to adjust the dosage if necessary. As with any medication, there may be potential side effects, and patients should be advised to report any unusual symptoms to their healthcare provider.

For patients and prescribers interested in using this Probenecid 100 mg/ml oral suspension in a capsule formulation, it is important to note that it should be stored at room temperature and protected from light and moisture to maintain its efficacy. If you have any questions or require further information about this formulation, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide guidance and support to ensure the best possible treatment outcomes.

Other Uses

A small arrow pointing down

As a team of compounding pharmacists at Bayview Pharmacy, we carefully consider the versatility of our formulations. Probenecid, traditionally used as a uricosuric agent for the treatment of gout, hyperuricemia, and to prolong the half-life of antibiotics like penicillin, may also have additional, albeit less common, applications encapsulated in a solid dosage form. Our Probenecid 100 mg/ml Oral Suspension has been prepared within a two-piece capsule, typically utilizing either gelatin or vegetarian alternatives, to facilitate ease of administration while preserving dosage precision.

Though the primary use of Probenecid is well-established in managing conditions associated with excess uric acid, research suggests it may also function in an off-label capacity to aid in other therapeutic areas. For instance, Probenecid has been investigated for its potential to impact the transport of certain drugs across biological membranes, influencing their absorption and disposition within the body. This property could theoretically be harnessed to optimize drug delivery systems or to augment the bioavailability of certain medications, though such uses would require careful monitoring and further clinical validation.

Moreover, there is some evidence that Probenecid may interact with renal transporters involved in the excretion of various endogenous and exogenous compounds, potentially modifying the renal clearance of substances other than uric acid. This can be of particular interest in the field of clinical pharmacokinetics, where Probenecid could be utilized to study renal drug elimination pathways or to modulate the excretory profile of concomitant medications for therapeutic benefit. It is important to note that these other uses may not be as widely recognized or approved by regulatory agencies, thus requiring a more bespoke approach to patient care and clinical judgment when considering Probenecid beyond its standard indications.

Finally, we recognize that every patient is unique and that clinical needs evolve. Our compounding expertise allows us to tailor make dosage forms like the Probenecid 100 mg/ml Oral Suspension, addressing each individual's requirements while maintaining the high standards of pharmaceutical care. Should patients or prescribers have questions or wish to explore the potential other uses of our Probenecid formulation, we encourage you to reach out to us. Our team stands ready to provide guidance, support, and the necessary information to ensure the safe and effective use of this medication.
