Overview of Ioril-10

Property Description
Active ingredient Isoxsuprine Hydrochloride
Form Tablet and Injection (Solution)
Pharmacological class Vasodilator and beta-adrenergic agonist
General purpose Enhancing blood circulation and relaxing smooth muscle
Origin Synthetic compound

Ioril-10 is a commercial pharmaceutical preparation containing the synthetic active ingredient Isoxsuprine (as the hydrochloride salt), which is positioned within the pharmacological classification of a vasodilator and a beta-adrenergic agonist. This classification confirms its targeted function of promoting the relaxation of smooth muscle. Ioril-10 specifically differentiates itself within the market by providing a non-complex, single-entity Isoxsuprine formula. The drug's mechanism of action, causing blood vessel widening, is clinically recognized for its ability to improve peripheral blood flow. This confirms for the patient that the medicine works to increase the necessary blood supply to tissues.

Ioril-10 is manufactured in multiple dosage forms, including the most common tablet for oral administration, alongside a sterile solution for injection for parenteral delivery. This variety of forms allows it to be used in different therapeutic settings, from continuous maintenance to acute intervention. The general therapeutic purpose is directly linked to its vasodilating action, a function key to the overall aim of enhancing blood circulation to address inadequate tissue perfusion. Furthermore, the capacity of Isoxsuprine to relax uterine smooth muscle is leveraged for its acknowledged use as a tocolytic agent. This indicates that the medication is also used when a doctor needs to suppress unwanted uterine contractions.

Overdose and Emergency Response

Overdose and when to seek help

The following information details the officially documented signs of overdosage and the mandatory emergency actions required, as stated in government regulatory sources for Isoxsuprine Hydrochloride (Ioril-10).


Documented Overdose Manifestations

Official labeling indicates that overdosage may lead to a symptom cluster including weakness, lightheadedness, fainting, nausea, and vomiting. Due to the drug's known actions, the overdose profile also notes the potential for expected cardiovascular symptoms.

Emergency Actions and Required Medical Help

Seek emergency medical attention if an overdosage is suspected. Specific, life-threatening symptoms trigger the requirement to immediately call emergency services (e.g., 911). These severe manifestations include if the person has collapsed, had a seizure, is experiencing trouble breathing, or cannot be awakened (unresponsiveness).

Official Management Procedures

Management procedures described in the regulatory documents focus on supportive care. For oral overdosage, management may involve gastric lavage. Furthermore, the administration of a nonselective beta-blocker may be necessary and may be given intramuscularly, as determined by medical staff. No specific antidote is explicitly documented in the available regulatory information.

Therapeutic Uses of Ioril-10

Quick Facts: Uses of Ioril-10

  • May be used to address: Premature labor
  • May be considered for: Conditions related to poor blood flow to the brain (cerebral vascular insufficiency)
  • May help manage: Disorders affecting the blood vessels outside of the heart and brain (peripheral vascular diseases)

Ioril-10 is a medication that may be prescribed by a healthcare professional to support the management of certain vascular and obstetrical conditions. Its approved uses include addressing symptoms related to premature labor.

For conditions involving the blood vessels, the medication may be considered for the management of peripheral vascular diseases such as arteriosclerosis obliterans and Buerger's disease. These conditions involve issues with circulation in the limbs. Ioril-10 may also be used to assist in the management of Raynaud's phenomenon, a condition characterized by reduced blood flow to the fingers and toes.

Additionally, the treatment may offer support for symptoms associated with cerebral vascular insufficiency, a condition where there is inadequate blood flow to the brain.

What should I know about interactions with other medicines?

Interactions with other medicines and products

This section describes the officially documented interaction patterns for Ioril-10 (Isoxsuprine Hydrochloride) as classified in government regulatory labeling.

Pharmacodynamic Interaction Constraints

The primary documented interaction is categorized as pharmacodynamic, resulting from the combination of Ioril-10 with other agents that lower blood pressure. Co-administration with other vasodilators or anti-hypertensive drugs may lead to an additive hypotensive effect, which carries a regulatory-documented risk of hypotension.

Official Regulatory Status of Other Interactions

Interaction Type Regulatory Status (Official Documentation)
Drug-Drug Contraindications No known contraindications to oral use are stated when the medicine is administered at recommended levels.
Metabolic (CYP/Transporter) No specific pharmacokinetic interactions that alter drug exposure via metabolic enzymes or drug transporters are formally documented in the regulatory label.
Food, Alcohol, or Herbal Products No formal interaction patterns with food, alcohol, or herbal products that alter drug exposure or clearance are documented in the official regulatory label.
Timing Requirements No mandatory time-separation rules are documented for any co-administered substance in the regulatory label.

This interaction profile is characterized by the absence of explicit metabolic or transporter interaction data, with regulatory constraints focusing strictly on the additive hypotensive risk inherent to the medicine's vasodilating classification.

Mechanism of Action

Ioril-10 functions as an agonist by binding to the heterodimeric Interleukin-10 Receptor complex, comprised of the IL-10R1 and IL-10R2 subunits, which is expressed on various hematopoietic cells, including monocytes, macrophages, and T cells. This binding initiates signal transduction through the intracellular JAK-STAT pathway. Specifically, it induces the phosphorylation of Janus kinases (JAK1 and TYK2), which subsequently phosphorylate the receptor subunits.

This phosphorylation recruits and activates the cytoplasmic transcription factor STAT3 (Signal Transducer and Activator of Transcription 3). Activated STAT3 then translocates to the nucleus where it modulates gene expression. This molecular pathway leads to the upregulation of anti-inflammatory mediators, such as Suppressor of Cytokine Signaling 3 (SOCS3), which dampens further signal transduction. Concurrently, it inhibits the nuclear translocation and activity of pro-inflammatory transcription factors, such as NF-kB. The downstream intracellular cascade results in the decreased transcription and secretion of pro-inflammatory cytokines, including TNF-alpha and Interleukin-6 (IL-6), primarily by myeloid cells. The systemic physiological consequence is the modulation of immune and inflammatory cellular processes, limiting the release of specific pro-inflammatory signaling molecules.

Dosage and Administration Information

Ioril-10 (Isoxsuprine) is administered using officially approved methods, including the oral route via 10 mg and 20 mg tablets, and a solution for injection for parenteral delivery. The injectable form, used for acute control, supports both intravenous and intramuscular delivery, with precise dosing rates determined by the supervising clinician based on the specific clinical scenario.

The standard adult oral regimen for routine management of vascular conditions typically falls within the 10 mg to 20 mg dose range per administration, scheduled for three or four times daily. This regimen establishes the pattern for long-term maintenance after initial symptoms are managed. The oral tablets may be taken with meals, milk, or antacids if necessary to mitigate potential stomach discomfort.

The official use protocol often involves transitioning a patient from the acute parenteral use to the scheduled oral regimen for maintenance. Procedurally, if a dose is missed and it is near the time for the next dose, instructions specify that the missed dose should be skipped, and the regular schedule resumed without taking a double amount. Regarding specific populations, the safety and effectiveness of Ioril-10 have not been established for use in pediatric patients.

Recent Clinical Evidence

Research evidence / Overview of studies for Ioril-10


Evidence for Use in Premature Labor and Threatened Abortion

Research has explored Ioril-10 in contexts related to conditions involving periods of heightened symptoms such as premature labor and threatened abortion. Research examined outcomes related to episodic or acute changes in contractions, including monitoring changes in the timing of delivery over short-term observation periods of 24 to 48 hours. The study populations typically included pregnant women between 24 and 37 weeks of gestation who were studied in the context of premature delivery.

The research base primarily consists of systematic reviews and meta-analyses that synthesize data from many older randomized controlled trials (RCTs). These findings describe patterns observed in the studies related to measured intervals of pregnancy continuation and measurements of uterine quiescence. Studies also monitored neonatal outcomes like birth weight and infant health following delivery.

However, the evidence is not uniform. The methodological quality of many of the aggregated primary studies evidence quality varies across studies, and many are described as small and dating from earlier periods. Regulatory records show that the formal application for this indication was not completed, impacting the scope of the available evidence base. Long-term effects are not fully established for both the mother and the infant, and there is limited information for long-term outcomes beyond the immediate post-treatment period.


Evidence for Use in Peripheral Vascular Conditions and Cerebral Insufficiency

This part will describe the research base for the medicine's use in conditions involving insufficient blood flow to the limbs and brain, focusing on the historical controlled studies and the physiological measures used to evaluate circulation and functional parameters.

The research was studied for its application in contexts related to conditions marked by functional limitations due to poor blood flow in the limbs (Peripheral Vascular Diseases) and the brain (Cerebral Vascular Insufficiency). Studies was evaluated in historical controlled studies, including some double-blind crossover trials where patients received both the study medicine and an inactive substance for comparison.

Data were not consistently reported across these earlier studies. Some research data show patterns related to measured changes in circulation. Conversely, one controlled study examined parameters of blood flow and functional ability, and data showed no change in those specific measurements. The official regulatory assessment indicated that the existing evidence structure did not meet the defined criteria for sufficiency. Therefore, comparative evidence is lacking from contemporary trials, and there is limited information for long-term outcomes.
