Product Overview

Assurans Tablet contains Sildenafil Citrate, a selective phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing levels of cyclic guanosine monophosphate (cGMP), a natural chemical messenger responsible for relaxing smooth muscles and widening blood vessels. In pulmonary arterial hypertension, Assurans helps relax blood vessels in the lungs, reducing pressure in pulmonary arteries and improving blood flow. This allows the heart to pump blood more efficiently and may improve exercise capacity and breathing symptoms.

Product Composition

  • Sildenafil Citrate – Active PDE5 inhibitor
  • Vasodilator agent
  • Smooth muscle relaxant
  • cGMP pathway enhancer

Key Benefits

  • Helps manage pulmonary arterial hypertension:
    Assurans relaxes blood vessels in the lungs, helping reduce pulmonary artery pressure and improving blood circulation.
  • Improves exercise capacity:
    By reducing resistance in pulmonary blood vessels, it may help patients perform daily activities with less breathing difficulty.
  • Supports better heart function:
    Lower pressure in pulmonary arteries may reduce workload on the right side of the heart.
  • Improves blood flow:
    Sildenafil enhances vascular relaxation by supporting the nitric oxide–cGMP pathway.
  • Provides targeted pulmonary circulation support:
    It specifically helps improve blood flow through the lung arteries in patients with PAH.
  • Supports vascular health:
    Its vasodilating effect helps maintain smoother blood vessel function.

Precaution

Condition / SituationPrecaution
Heart diseaseUse cautiously as Sildenafil can affect blood pressure and cardiovascular function
Low blood pressureMay further lower blood pressure and cause dizziness or fainting
Liver problemsReduced metabolism may increase Sildenafil levels in the body
Kidney problemsDose adjustment may be required in severe kidney impairment
Alcohol consumptionMay increase dizziness and blood pressure-related effects

 

Important Precaution Points

  • Assurans Tablet should be taken only as prescribed, especially when used for pulmonary arterial hypertension (PAH).
  • Do not stop the medicine suddenly without medical advice, as it may worsen pulmonary hypertension symptoms.
  • Avoid using Assurans with nitrate medicines, as the combination can cause a dangerous drop in blood pressure.
  • Patients with heart conditions should inform their healthcare provider before starting treatment.
  • Regular monitoring may be required to check blood pressure, heart function, and response to treatment.
  • Inform your doctor about all prescription medicines, over-the-counter drugs, and supplements being used.
  • Seek medical attention if symptoms such as severe dizziness, chest pain, sudden vision changes, or fainting occur.

Usages

Assurans Tablet should be taken exactly as prescribed by a healthcare professional. It is usually used regularly for pulmonary hypertension management rather than as an occasional medicine.

How to Use

â–¸ Take orally with water:
Swallow the tablet with a glass of water as directed.

â–¸ Do not stop suddenly:
Stopping without medical advice may worsen pulmonary hypertension symptoms.

â–¸ Take consistently:
Regular use provides better control of pulmonary blood vessel pressure.

â–¸ Avoid grapefruit products if advised:
Certain foods may affect Sildenafil metabolism.

â–¸ Inform your doctor about other medicines:
Especially heart medicines, blood pressure medicines, and nitrate-containing drugs.

Uses

Assurans Tablet (Sildenafil Citrate) is mainly used for:

â–¸ Pulmonary Arterial Hypertension (PAH)

Assurans helps relax narrowed pulmonary blood vessels, reducing pressure in the arteries that supply blood to the lungs. This improves blood flow and reduces strain on the heart.

â–¸ Improvement in Exercise Ability

By improving pulmonary circulation, it may help patients perform physical activities more comfortably and reduce symptoms such as shortness of breath.

â–¸ Management of Pulmonary Vascular Conditions

It may be prescribed in certain pulmonary vascular disorders where increased pressure in lung blood vessels affects circulation.

â–¸ Blood Flow Support

Sildenafil improves vascular relaxation and supports better circulation through its PDE5-inhibiting action.

Assurans Tablet contains Sildenafil Citrate and is primarily used for the treatment of pulmonary arterial hypertension (PAH) by improving blood flow in lung arteries.

Q. How does Assurans work?
It inhibits the PDE5 enzyme, increasing cGMP levels. This relaxes blood vessels and helps improve circulation, especially in pulmonary arteries.

Q. Is Assurans the same as Sildenafil used for erectile dysfunction?
The active ingredient is the same (Sildenafil Citrate), but Assurans is primarily prescribed for pulmonary arterial hypertension at doses and schedules decided by a doctor.

Q. How long does Assurans take to work?
The response varies depending on the condition being treated and individual patient factors. Regular use as prescribed helps maintain its effect.

Q. Can Assurans be stopped suddenly?
No. It should not be discontinued without medical advice, as symptoms of pulmonary hypertension may worsen.

Q. Can Assurans be taken with heart medicines?
Some heart medicines, especially nitrate-containing medicines, should not be combined with Sildenafil due to the risk of severe blood pressure reduction.

Q. Does Assurans lower blood pressure?
Yes, Sildenafil may cause mild blood pressure reduction due to its blood vessel-relaxing effect.

Q. Can alcohol be consumed while taking Assurans?
Excess alcohol should be avoided because it may increase dizziness and blood pressure-related side effects.

Q. Who should avoid Assurans Tablet?
People taking nitrates, Riociguat, or those with certain serious heart conditions should avoid it unless specifically advised by a healthcare professional.

Q. Can Assurans improve breathing in pulmonary hypertension?
By improving blood flow through pulmonary arteries, it may help reduce symptoms such as exercise-related breathlessness in some patients.

 

Interaction

Medicine / Substance Effect
Nitrate medicines Severe and potentially life-threatening drop in blood pressure
RiociguatDangerous blood pressure reduction; combination is not recommended
Alpha-blockersIncreased risk of dizziness and low blood pressure
CYP3A4 inhibitors Increased Sildenafil levels and side effects
Other PDE5 inhibitorsIncreased risk of adverse effects

 

Important Interaction Advice

  • Avoid nitrate medicines completely:
    Sildenafil with nitrates may cause a sudden and severe fall in blood pressure, which can be dangerous.
  • Do not combine with Riociguat:
    Both medicines increase cGMP activity, and their combination may cause severe hypotension.
  • Use caution with blood pressure medicines:
    Combined effects may result in dizziness, weakness, or fainting.
  • Avoid other PDE5 inhibitors:
    Combining similar medicines may increase side effects without improving benefits.
  • Limit alcohol intake:
    Alcohol may worsen dizziness and affect blood pressure control.
  • Inform your healthcare provider about all medications:
    Complete medicine information helps prevent harmful interactions and supports safer treatment with Assurans.
