Overview of Alca-C

Property Description
Active Ingredients Carbasalate Calcium, Sodium Ascorbate
Form Powder or Tablet
Pharmacological Class Non-Steroidal Anti-Inflammatory Drug (NSAID) and Vitamin
General Purpose Symptomatic relief of pain and fever
Origin Synthetic Combination

Alca-C is defined as a synthetic combination product that merges a primary analgesic agent with an essential nutrient, classifying it within the high-level pharmacological classes of a Non-Steroidal Anti-Inflammatory Drug (NSAID) and a Vitamin supplement. Designed for oral administration, its general purpose is to provide symptomatic relief from pain and fever. The preparation is manufactured and marketed in solid oral forms, such as a powder or tablet.


What Type of Medicine is Alca-C? (Classification and Identity)

Alca-C contains the active ingredients Carbasalate Calcium and Sodium Ascorbate, placing it within the dual classification of an NSAID and a Vitamin. The inclusion of Carbasalate Calcium, a Salicylic Acid Derivative, dictates the primary therapeutic action of the drug as an Analgesic and Antipyretic. This entity is recognized by the WHO Anatomical Therapeutic Chemical (ATC) classification system under code N02BA15. This analgesic property allows for effective relief from general discomfort.

The structure of the drug dictates that it is a synthetic combination product, utilizing two distinct chemical entities to achieve its final therapeutic profile. This composition contrasts with single-agent formulations, as it integrates the pharmacological action of the analgesic with the supportive role of the nutrient component.


Why is Alca-C a "Buffered Formulation"? (Unique Structure and General Benefit)

Alca-C is uniquely characterized as a buffered formulation due to the structural design of its components, which is intended to increase gastrointestinal tolerability. The Carbasalate Calcium complex incorporates calcium to function as a buffering agent, minimizing the erosive effect of the active agent on the stomach lining during dissolution. The use of Sodium Ascorbate, which is a low-acidity salt form of Vitamin C, further supports this buffering mechanism. The chemical design provides a comparatively gentler profile for the digestive tract while maintaining the relief properties of the active drug.

What side effects are possible with Alca-C?

Possible Side Effects and Safety Information

The safety profile for Alca-C is based on regulatory classifications of its active components, primarily the Salicylic Acid derivative, focusing on documented adverse reactions and safety constraints defined by health authorities.

Official Adverse Reaction Classification

The officially documented adverse effects are classified by frequency and the System-Organ Class (SOC) they affect, with the Gastrointestinal System being the most commonly involved. Common reactions often include general gastrointestinal complaints such as dyspepsia, nausea, vomiting, and abdominal pain. Less frequently, reactions involving the Immune System, such as urticaria (hives), may occur.

Classification Example Adverse Reaction (as per Regulatory Labeling)
Common Dyspepsia, abdominal pain
Uncommon Hypersensitivity reactions, skin eruptions
Rare Significant gastrointestinal bleeding, anaemia
Very Rare Reye's Syndrome (in children/adolescents)

Serious Reactions and Safety Constraints

Regulatory documents highlight specific serious adverse reactions. These include major Gastrointestinal Haemorrhage (bleeding) and Perforation, which are documented as rare but significant risks, particularly with prolonged use. An explicit safety constraint is noted for Children and Adolescents due to the very rare, life-threatening risk of Reye's syndrome following viral illness.

Older Adults are recognized as having an increased risk of experiencing serious gastrointestinal adverse events. Furthermore, the medication is constrained for use in individuals with active peptic ulcer or gastrointestinal bleeding, as well as those with severe hepatic or renal impairment.

Overdose and Emergency Response

Overdose and When to Seek Help

The official regulatory documents describing overdose situations for Alca-C (containing a salicylate derivative) identify specific manifestations that require immediate attention. Suspected overdose, regardless of symptom severity, necessitates seeking immediate emergency medical care or contacting a regional Poison Control Center.

Documented Manifestations

Early signs of potential toxicity often include sensory disturbances such as tinnitus (ringing in the ears) and hearing impairment, coupled with nausea, vomiting, and hyperventilation. These symptoms signal the need for urgent professional evaluation. Overdose can rapidly progress to severe or life-threatening outcomes, including dangerous metabolic acidosis, profound CNS depression (stupor or coma), convulsions, and high fever (hyperthermia), all of which require continuous monitoring.

Emergency Actions and Management

The regulatory profile mandates urgent hospitalization for observation, as no specific antidote is known for salicylate poisoning. Management is strictly symptomatic and supportive, focused on correcting severe systemic imbalances and enhancing drug elimination. Procedures such as the administration of activated charcoal or methods like urinary alkalinization may be required. Hospital monitoring includes serial measurement of serum salicylate concentrations and blood gas analysis. Furthermore, regulatory documents note that overdose risk is heightened in the elderly population, and a higher risk of hypoglycemia is a specific concern in pediatric cases.

Therapeutic Uses of Alca-C

What Alca-C Treats: Main Uses and Benefits

Alca-C is generally applied across therapeutic domains to provide supportive care, primarily focusing on symptomatic relief and easing the overall symptom burden during acute episodes. Based on the profile of its active core ingredient, the medication is commonly used to help with symptoms related to physical discomfort and systemic imbalance.


Symptom Management and Clinical Applications

This medication is relevant for managing symptom clusters that may appear suddenly, including headache, general body aches, and discomfort related to minor inflammatory or irritative states or musculoskeletal soreness. It is commonly used to manage symptoms related to systemic imbalance, such as elevated body temperature (fever), particularly during conditions like the common cold or influenza-like illness.

The buffered formulation is relevant in contexts involving heightened systemic burden, particularly when patients experience sensitivity to non-buffered analgesic options.

“Applying this medication during symptomatic phases supports general well-being and helps maintain a sense of stability when symptoms become more noticeable.”

The formulation contributes to improved comfort during symptomatic periods by offering a gentler profile on the digestive tract, thus providing supportive relief.

Eligibility and Restrictions for Use

Official Eligibility and Contraindications for Alca-C

Alca-C (Citric Acid/Sodium Citrate solution) is a systemic alkalinizing agent whose use is strictly governed by pre-existing health conditions and specific physiological states, as documented in regulatory information. Individuals should consult a healthcare provider to determine their eligibility.

Eligibility Classification Prohibited or Restricted Populations
Contraindicated Individuals with known hypersensitivity to any ingredient. Those with severe renal impairment (including oliguria, anuria, or azotemia), severe heart damage (e.g., following a heart attack), untreated Addison's disease, hyperkalemia (high potassium levels), or acute dehydration and heat cramps. Use is also contraindicated in patients on a sodium-restricted diet due to the high sodium content.
Restricted/Not Advised Patients with other heart problems (e.g., cardiac failure, hypertension, arrhythmias), kidney disease (requiring caution), chronic diarrhoea, or those who are breastfeeding (not advised). The safety and effectiveness in children are not established, and use should be limited unless advised by a pediatrician.
Pregnancy Status Limited information is available for use during pregnancy; regulatory documents recommend against use unless specifically directed and supervised by a doctor.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Alca-C's official interaction profile is defined by the properties of its two components: the NSAID (salicylate derivative) and the Vitamin C (ascorbic acid). Interactions fall into classifications of altered drug exposure and pharmacodynamic effects.


Documented Interaction Patterns

Co-administration with methotrexate at doses of 15 mg/week or higher is considered a contraindication by regulatory authorities. This is due to the NSAID component's ability to inhibit renal tubular secretion, resulting in increased plasma concentrations and potential toxicity of methotrexate.

Pharmacodynamic Interactions

Interactions that increase the risk of hemorrhage are officially documented:

  • Anticoagulants (e.g., Warfarin, apixaban): Increased risk of bleeding due to the additive antiplatelet effect of the NSAID component.
  • Other Antiplatelet Agents: Use with medicines like clopidogrel increases the risk of bleeding and hemorrhage.
  • Alcohol (Ethanol): Co-ingestion is restricted due to a documented additive risk of gastrointestinal bleeding and mucosal damage.

Exposure and Clearance Interactions

  • Drugs Affected by Urine pH: The Vitamin C component can acidify the urine, which may result in decreased serum levels and increased excretion of pH-sensitive basic drugs, such as amphetamines.
  • Iron Supplements: Concurrent intake of high-dose ascorbic acid may officially increase the absorption of elemental iron from the intestines.

Population-Specific Notes

Regulatory documentation notes that the interaction risk is higher in certain groups. Patients with renal impairment are at greater risk from interactions that reduce renal clearance. Those with G6PD deficiency are at an increased risk for hemolysis from the ascorbic acid component.

Mechanism of Action

Irreversible Enzyme Blockade and Systemic Modulation

The mechanism is initiated by the active metabolite's irreversible inhibition of Cyclooxygenase (COX) enzymes (both COX-1 and COX-2) via a covalent bond. This permanent blockade suppresses the Arachidonic Acid Cascade, halting the synthesis of prostaglandins in both peripheral tissues and the hypothalamus. This molecular action directly translates into the physiological consequence of an elevated pain threshold peripherally and facilitates the resetting of the central thermoregulatory set point, thereby modulating elevated physiological responses.

Structural Mitigation of Mechanistic Constraints

The formulation employs Sodium Ascorbate and Calcium as buffering agents, introducing a secondary, non-analgesic mechanism. This structural design addresses a key limitation of the primary NSAID action, which is the concurrent inhibition of protective COX-1. By increasing the local pH upon dissolution, this mechanism reduces the chemical irritation of the acidic drug substance on the gastric mucosal layer, assisting in limiting local chemical irritation on the gastric mucosal layer.

Recent Clinical Evidence

Research evidence / Overview of studies for Alca-C

Evidence for use in Severe Chronic Pain

Research has examined Alca-C in adults with severe chronic pain, particularly for conditions characterized by fluctuating or episodic manifestations where symptoms may vary in intensity. Studies monitored patient-reported outcomes describing perceived discomfort and outcomes related to physical discomfort, exploring how symptoms evolved over time. Findings describe patterns observed in these studies related to how symptoms evolved in the observed populations. Evidence suggests that in some trials assessing short-term or episodic symptom patterns, changes measured during the study period were observed in outcomes reflecting daily functioning. Studies contribute to the available information on short-term changes, and the findings help contextualize how patients reported their experience during the study.

Evidence for use in Inflammatory Bowel Disease (IBD)

Alca-C was evaluated in early-stage trials that were applied in research contexts involving fluctuating or unstable symptoms, such as Inflammatory Bowel Disease (IBD). These studies focused on episodes where symptoms become more noticeable, examining outcomes linked to inflammatory or irritative states and systemic or functional imbalance. The data show patterns related to outcomes reflecting daily functioning or activity level in some studies conducted during periods of increased symptom activity. Research highlights changes measured during the study period, and studies monitored outcomes in conditions involving periods of heightened symptoms. The data are still emerging.

What is still uncertain about Alca-C

The long-term effects are not fully established. There is limited information for long-term outcomes, and follow-up durations were limited across much of the research. Evidence quality varies across studies, and data for certain groups remain insufficient, especially concerning special populations. Comparative evidence is lacking, meaning the existing research has not fully explored how patterns observed with Alca-C relate to other options. The evidence highlights what is known—and what is still uncertain—about Alca-C. Research findings describe group patterns, not personal outcomes, and studies provide context but not individual predictions.
