Property Description
Active Ingredient Bisoprolol Fumarate
Pharmacological Class Cardioselective Beta Blocker
Form Round, Pink Tablet (5 mg strength)
Common Use Type Management of cardiovascular conditions
Origin/Status Prescription-only (Rx) medication

Identifying C 86: Definition and Class

The identifier C 86 is an imprint code found on a specific 5 mg strength tablet, identifying the active ingredient and manufacturer, which is typically Aurobindo Pharma. The drug's active ingredient is Bisoprolol Fumarate, which is the official International Nonproprietary Name (INN) for the substance.

This medication is classified as a cardioselective beta blocker, meaning it primarily targets \beta1 receptors in the heart. This targeted action is clinically recognized for its effectiveness in reducing heart rate and blood pressure, which helps decrease the overall workload on the heart.


Composition, Form, and Therapeutic Focus

The "C 86" tablet contains Bisoprolol Fumarate 5 mg as its active ingredient, along with various inactive ingredients (excipients) necessary to form the small, round, pink tablet. It is formulated for the oral route of administration.

Bisoprolol Fumarate is differentiated by its high selectivity for cardiac receptors at therapeutic doses, which is supported by its pharmacology. This characteristic allows for its typical use in the long-term management of cardiovascular conditions where controlling rhythm and reducing strain on the heart are essential. The specific "C 86" imprint, color, and size serve as a key differentiator for the generic 5 mg strength produced by this particular manufacturer.

What side effects are possible with C-86?

Possible side effects and safety information

Official Adverse Reaction Profile

The safety profile of Bisoprolol Fumarate (C-86) is officially documented by government regulatory agencies, which classify potential effects by frequency and the body system affected (System-Organ Class or SOC).

Common adverse reactions, occurring in more than 1 in 100 patients, include fatigue, dizziness, headache, and gastrointestinal disturbances such as nausea, vomiting, diarrhea, or constipation. Bradycardia (slowed heart rate) and a feeling of coldness or numbness in the extremities are also commonly listed. These common effects, particularly headache and dizziness, are often noted to occur primarily at the beginning of therapy.

Uncommon side effects (occurring in less than 1 in 100 patients) include hypotension (low blood pressure), muscle weakness, sleep disturbances, and depression. A worsening of pre-existing heart failure symptoms is also classified as uncommon. In patients with a history of bronchial asthma or COPD, there is an uncommon risk of bronchospasm.

Serious Safety Constraints

Official labeling defines specific high-level constraints and cautions. Bisoprolol Fumarate is contraindicated in conditions such as acute decompensated heart failure, cardiogenic shock, and specific severe heart conduction disorders (e.g., symptomatic bradycardia).

A critical safety pattern is related to the abrupt termination of treatment. Suddenly stopping this medication, especially in patients with coronary artery disease, is documented to carry a risk of a transitory worsening of the heart condition, including the potential for myocardial infarction or severe exacerbation of angina. The therapy should never be discontinued suddenly. Cautions also apply to special populations, including the need for careful use in patients with renal or hepatic impairment and in those with diabetes due to the potential for masking signs of low blood sugar.

Overdose and Emergency Response

Overdose of C-86 (Bisoprolol Fumarate) is primarily associated with severe and potentially life-threatening physiological effects on the cardiovascular system, as documented in regulatory information. All suspected cases of overdose require immediate medical evaluation.

Documented Overdose Manifestations

System Affected Clinical Presentation
Cardiovascular Profound bradycardia (slow heart rate), severe hypotension (low blood pressure), and disturbances in cardiac conduction (A-V Conduction Blocks).
Systemic Hypoglycemia (low blood sugar), central nervous system effects including fatigue and somnolence.
Respiratory Bronchospasm (airway constriction).

Severe Outcomes and Emergency Action

Overdose exposure may lead to severe outcomes such as Cardiogenic Shock or Acute Heart Failure. Due to the high potential for life-threatening events, individuals must seek immediate medical attention and contact emergency services immediately upon any suspicion of overdose or the onset of severe symptoms. Management procedures, as described in official labeling, are symptomatic and supportive, as no specific antidote is known for Bisoprolol Fumarate overdose.

Management and Monitoring

Intensive hospital monitoring of cardiac function and blood pressure is required. Specific interventions may include the use of agents like Intravenous Glucagon for refractory hypotension. Special caution is noted for patients with pre-existing heart failure, where overdose may acutely exacerbate their condition.

Therapeutic Uses of C-86

Quick Facts: Uses of C-86

  • Chronic Pain: Indicated for the management of chronic, moderate-to-severe pain.
  • Rheumatoid Arthritis: Used as part of a therapeutic regimen to reduce the symptoms of active rheumatoid arthritis.
  • Psoriasis: May be utilized to help control the manifestations of severe psoriasis in certain adult patients.

C-86 is a prescription medication used to address a limited range of conditions, primarily focusing on managing symptoms. One of its main therapeutic domains is the management of chronic, moderate-to-severe pain that requires continuous, around-the-clock analgesic treatment for an extended period. It is intended for use in situations where alternative treatment options are not suitable or have been found inadequate.

The medication is also utilized in rheumatology. It is indicated to help reduce the signs and symptoms of active rheumatoid arthritis, often as a component of a broader treatment plan. Clinical experience suggests that C-86 may help patients achieve a reduction in discomfort and stiffness associated with this condition, contributing to improved daily function.

Furthermore, C-86 may be a therapeutic option for certain adult patients who experience severe, debilitating psoriasis. In this context, it is used to help control the manifestations of the disease, though it is not a curative treatment. Treatment with C-86 should be guided by a specialist.

Eligibility and Restrictions for Use

Who Can and Cannot Use C-86?

The official population eligibility for C-86 (Bisoprolol Fumarate) is defined by regulatory bodies and strictly outlines which patients may use the medication and which are absolutely excluded. Eligibility is primarily established for the adult population.

Absolute Contraindications

C-86 must not be used in patients with the following severe conditions, as established in official labeling:

  • Cardiogenic Shock or Overt Decompensated Cardiac Failure.
  • Second or Third-Degree Atrioventricular (AV) Block without a permanent pacemaker.
  • Marked Sinus Bradycardia or Sick Sinus Syndrome.
  • Severe Bronchial Asthma or Severe Chronic Obstructive Pulmonary Disease (COPD).

Restrictions and Limitations

Population Group Regulatory Status and Limitation
Pediatric Patients Safety and efficacy have not been established; use is generally not recommended.
Pregnancy Use only if the potential benefit outweighs the potential risk to the fetus.
Hepatic/Renal Impairment Use with caution; dose adjustments may be required for severe impairment.
Diabetes Mellitus Use with caution as the drug may mask signs of hypoglycemia.

These restrictions define the formal boundaries for use, establishing who is eligible, who is conditionally eligible, and who must be excluded from treatment with C-86.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The interaction profile of Bisoprolol Fumarate (C-86) is defined by potent pharmacodynamic effects that require specific regulatory constraints, as documented in official government labeling.


Contraindicated Combinations

Co-administration with other Beta-Blocking Agents, including topical forms, is formally contraindicated due to the risk of excessive systemic beta-blocking activity. Centrally-Acting Antihypertensive Drugs (e.g., Clonidine, Methyldopa) are also contraindicated. This combination may cause a severe reduction in heart rate and cardiac output, necessitating a mandatory sequencing rule for discontinuation.


Documented Pharmacodynamic Risks

Class I and Class III Antiarrhythmic Drugs (e.g., Disopyramide, Amiodarone) and specific Calcium Antagonists (e.g., Verapamil, Diltiazem) may potentiate the atrio-ventricular conduction time and increase the risk of hypotension.

The medicine may increase the blood sugar lowering effect of Insulin and Oral Antidiabetic Drugs, and this interaction can mask the typical symptoms of acute hypoglycemia.


Substance and Population Notes

Alcohol (Ethanol) consumption is associated with additive effects in lowering blood pressure. The drug’s absorption is not significantly affected by food intake.

Caution is noted for geriatric patients with significant renal or hepatic dysfunction due to the potential for increased drug effects resulting from reduced systemic clearance.

Mechanism of Action

The mechanism of action for C-86 (Bisoprolol Fumarate) is centered on highly selective beta1 adrenergic receptor antagonism, which modulates sympathetic signaling in the cardiovascular and renal systems to reduce the overall workload and oxygen demand of the myocardium.

Selective Blockade of Cardiac Sympathetic Drive

C-86 acts as a competitive antagonist, engaging the beta1 adrenergic receptors primarily in the heart’s conduction system and muscle tissue. By occupying these sites, the drug prevents activation by stimulating stress hormones (catecholamines), thereby dampening the signaling pathway. This blockade leads to a core physiological cascade: a negative chronotropic effect (slowing the heart rate) and a negative inotropic effect (reducing the force of contraction).

Modulation of Systemic Pressure Pathways

The mechanism also extends to beta1 receptors on the juxtaglomerular cells in the kidneys. Blocking these receptors inhibits the release of renin, the enzyme responsible for initiating the powerful Renin-Angiotensin System ( RAS) cascade. This modulation affects the regulation of systemic vascular tone.

Mechanistic Selectivity and Constraints

The drug is characterized by its high beta1 selectivity, but this preference is dose-dependent. At significantly high concentrations, the mechanism can extend to beta2 receptors in non-cardiac tissues, potentially altering physiological responses in those areas. This inherent dose-related constraint is a key aspect of its overall mechanistic profile.
