Overview of Папаверин буфус

Property Description
Active ingredient Papaverine hydrochloride
Form Injection solution
Pharmacological class Vasodilator, Antispasmodic
Common use Relief of smooth muscle spasm
Origin Synthetic or Semi-synthetic

What Type of Medicine is Папаверин буфус and its Classification?

Папаверин буфус is a dedicated, prescription pharmaceutical preparation whose identity rests on the active ingredient, Papaverine hydrochloride (INN). The compound is a member of the benzylisoquinoline alkaloid chemical group, and its classification as a potent, direct-acting smooth muscle relaxant and vasodilator is clinically recognized in pharmacological literature. While its origins trace to opium, the Papaverine used in modern production is predominantly synthetic or semi-synthetic, which is the preferred manufacturing approach for ensuring consistent high purity for therapeutic applications.

Composition and Physical Form of Папаверин буфус

The medication is formulated as a sterile injection solution, specifically intended for parenteral administration via intramuscular or intravenous injection. Папаверин буфус is a single-ingredient product where the Papaverine hydrochloride is dissolved in a clear, sterile aqueous solution (Water for Injection). This specific dosage form facilitates a rapid therapeutic effect necessary for acute, time-sensitive interventions involving intense muscle constriction, distinguishing it from slower-acting oral Papaverine forms.

General Therapeutic Purpose and Action Principle

The primary general purpose of this medicine is to address and alleviate conditions characterized by involuntary smooth muscle spasms, providing relief from the resulting discomfort. The vasodilator action is key: Papaverine directly causes the relaxation of musculature lining the walls of arteries. This action enhances local blood flow by allowing constricted vessels to widen. By targeting and relaxing these constricted pathways, the medicine aims to counteract the compromised circulation caused by spasms and arterial narrowing.

What side effects are possible with Папаверин буфус?

Possible Side Effects and Safety Information

The safety profile for Papaverine hydrochloride, the active ingredient in Папаверин буфус, is documented by regulatory authorities based on official System-Organ Class (SOC) groupings and frequency classifications. The adverse reactions are primarily observed in several key physiological systems.

System-Organ Class Common Adverse Reactions
Gastrointestinal Constipation, Nausea, Abdominal discomfort
Nervous System Headache, Drowsiness, Dizziness
Vascular Hypotension, Flushing

Serious adverse reactions listed in regulatory documents include the potential for serious cardiac arrhythmias, such as ventricular premature beats, and the risk of hepatic hypersensitivity. The development of jaundice or significant changes in liver enzyme values during treatment requires official monitoring and may necessitate discontinuation.

Safety Constraints and Considerations

The official labeling notes specific safety constraints that restrict its use. The medicine is formally contraindicated in patients presenting with a complete Atrioventricular (AV) heart block. Caution is advised for use in patients with conditions such as glaucoma.

A key safety pattern documented is the link between administration speed and risk: the potential for acute severe adverse effects, including profound hypotension and cardiac arrhythmias, is heightened with a rapid rate of intravenous administration.

Regarding specific populations, the regulatory status for Papaverine is Pregnancy Category C, and its safety and effectiveness have not been established for pediatric use.

Overdose and Emergency Response

Overdose involving Papaverine hydrochloride requires immediate emergency medical attention, as mandated by regulatory guidance. Officially documented clinical manifestations often involve central nervous system depression, leading to symptoms such as drowsiness, weakness, and dizziness, and specialized signs like nystagmus (involuntary eye movement). Furthermore, the official profile describes vasomotor instability alongside effects like flushing, diaphoresis (sweating), and sinus tachycardia (fast heart rate).

The potential for severe outcomes is documented, including the risk of seizures and serious tachyarrhythmias, such as ventricular fibrillation, which are high-risk complications. Due to these potential life-threatening manifestations, individuals must seek emergency medical attention or call the Poison Help line immediately upon suspected overdose. Emergency response prioritizes protecting the patient's airway and supporting ventilation.

Management is strictly symptomatic and supportive, as no specific antidote is known, though calcium gluconate is noted as a theoretical consideration for cardiovascular effects. The treatment protocols officially described focus on addressing specific symptoms: hypotension is managed with intravenous fluids and vasopressors, while convulsions may require antiepileptic agents. Meticulous monitoring is required, including the continuous observation of vital signs, ECG, blood gases, and blood chemistry values, to guide supportive care as officially mandated.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Papaverine, the active component of this medication, may interact with other medicinal products, primarily impacting the cardiovascular and central nervous systems. These interactions are categorized by their potential clinical significance and the risk they present when combined.

Clinically Significant Interactions

Category Example Medicines/Classes Interaction Mechanism & Significance
CNS Depressants Benzodiazepines, Barbiturates, Anxiolytics, Sedatives, Hypnotics, Diphenhydramine May cause enhanced sedation or synergistic depressant effects on the central nervous system, increasing the risk of drowsiness.
Antihypertensives Aprocitentan, certain vasodilators Papaverine may increase the hypotensive activities of these agents, potentially leading to an exaggerated drop in blood pressure.
Levodopa Levodopa Papaverine may interfere with the action of Levodopa, potentially reducing its clinical effectiveness.

Important Interaction Constraints

  • Complete Atrioventricular (AV) Heart Block: The use of papaverine is contraindicated (should not be used) in patients with complete AV heart block due to the risk of inducing transient ectopic ventricular rhythms.
  • Conduction Disturbances: Papaverine should be administered cautiously in patients with pre-existing conduction disturbances, such as sinus bradyarrhythmia or partial AV block.

Mechanism of Action

Inhibiting Cellular Deactivation Through Phosphodiesterase (PDE)

The mechanism initiates with the non-selective inhibition of Phosphodiesterase ( PDE) enzymes, which are cellular enzymes responsible for hydrolyzing the signaling molecules cyclic AMP ( cAMP) and cyclic GMP ( cGMP). By blocking PDE activity, Papaverine elevates the intracellular concentration of these cyclic nucleotides. This molecular action triggers a cascade that results in the dephosphorylation of the Myosin Light Chain, a necessary condition for the cessation of smooth muscle contraction.

Direct Modulation of Contractility via Calcium and Myosin

The elevated levels of cAMP and cGMP activate specific protein kinases, leading to the inhibition of the Myosin Light Chain Kinase ( MLCK). In parallel, Papaverine also exerts a moderate blocking effect on L-type Calcium Channels on the muscle cell surface, which reduces the influx of Ca^2+ ions necessary for initiating tension. This dual mechanism provides a pathway for muscle relaxation, resulting in the physiological consequence of arterial widening (vasodilation) and a decrease in vascular tone.

Key Mechanism Characteristics

Papaverine is characterized as a direct-acting smooth muscle relaxant, meaning its action is immediate and independent of the body's nerve signals or regulatory transmitters, allowing for a direct effect on the muscle fibers themselves. Its non-selective mechanism produces a broad and rapid physiological change characterized by a reduction in muscle tension across various vascular and visceral smooth muscle beds.

Dosage and Administration Information

Administration Routes and Technique

Papaverine hydrochloride is formulated as an injection solution at a concentration of 30 mg/mL, which necessitates parenteral administration via either the intravenous (IV) or intramuscular (IM) route. The use of this solution is typically reserved for settings where professional supervision is standard. When the intravenous route is employed, the injection must be administered slowly, over a duration of approximately one to two minutes.


Standard Dosing and Frequency Patterns

The standard adult dose administered parenterally ranges from 30 mg to 120 mg for a single use. The medication is used on an intermittent basis for acute, time-sensitive scenarios; the dose may be repeated, as indicated, every three hours. A specific schedule exists for certain acute cardiac scenarios, allowing for two doses to be given approximately 10 minutes apart.


Population-Specific Usage

Standard usage patterns exist for the pediatric population. The dose is calculated based on body weight at 1.5 mg/kg per administration. For this group, the medicine is typically given via the intramuscular (IM) or subcutaneous (SC) route. A key procedural restriction is that the total amount of medicine administered to pediatric patients in a 24-hour period must not exceed 100 mg.

Recent Clinical Evidence

Evidence Overview: Studies for Папаверин Буфус

This overview describes the research that has examined the properties of Papaverine hydrochloride injection, focusing on the types of studies conducted, the outcomes they monitored, and the areas where certainty remains low. The existing research explores the use of Papaverine injection in two distinct areas: the context of internal organ spasms (visceral) and in the context of the acute narrowing of blood vessels (vascular spasm).


Evidence for Use in Acute Visceral Spasm

The research base for the context of spasms in the gastrointestinal, biliary, and urinary systems was studied for the purpose of examining outcomes related to physical discomfort during acute, disruptive episodes. This evidence is generally rooted in established clinical experience developed over many years and documented in older observational settings.

However, the evidence for this broad application is often historical. Limited information is available from recent, large-scale, placebo-controlled Randomized Controlled Trials (RCTs) focusing solely on outcomes related to physical discomfort during spontaneous, non-vascular visceral spasms. Comparative evidence is lacking, meaning research provides limited insight into how this medicine was evaluated in comparison to other treatments in this context.


Evidence for Use in Acute Procedural Vascular Spasm

Research exploring the use of the injection in research scenarios involving acute vessel narrowing includes more recent and structured studies, typically involving Randomized Controlled Trials (RCTs). This research was studied for use in adult patients undergoing specific procedures, such as diagnostic angiography or cardiac surgery, where outcomes related to systemic or functional imbalance due to vessel constriction was monitored.

Research describes patterns observed in spasm rates across tested groups, and variability is a noted factor depending on the specific artery and the administration method studied. For certain complex conditions, such as cerebral vasospasm, research indicates that any measured changes may be transient, meaning the scope of the findings is limited to the short-term observation period.
