Overview of Intramol

Property Description
Active ingredient Timolol
Form Ophthalmic solution (Eye drops)
Pharmacological class Beta-blocker
Common use Reduction of intraocular pressure (IOP)
Origin Synthetic compound

What is Intramol and How is it Classified?

Intramol is a prescription-only medicine that utilizes the synthetic compound Timolol as its core active ingredient, classified medically as a beta-adrenergic receptor antagonist, more commonly known as a beta-blocker (β-blocker). This classification defines the medication's precise, chemically defined action. The active substance itself is specifically identified as Timolol maleate.

Composition, Forms, and General Purpose

The medication uses Timolol as a single active ingredient product, typically administered as a sterile, aqueous ophthalmic solution (eye drops) for ocular administration. Although the active ingredient is also manufactured in oral tablets for systemic, non-ocular purposes, the ophthalmic solution is the relevant dosage form here, dissolving Timolol in a water-based vehicle. The general therapeutic purpose of this agent is to function as an ocular hypotensive agent, a role utilized for stabilizing eye pressure and lowering the pressure inside the eye.

The Timolol Mechanism: Basic Action

Timolol is chemically designated as a non-selective beta-adrenergic blocker (β-1 and β-2 antagonist), signifying its ability to block certain receptor signals across multiple receptor types. Its basic mechanism involves reduced fluid production of the aqueous humor within the eye, leading to a controlled reduction of pressure. This specific action, which minimizes the production rate of internal eye fluid, is the fundamental process by which Intramol achieves its general purpose of managing and stabilizing internal eye pressure.

What side effects are possible with Intramol?

Possible Side Effects and Safety Information

Intramol (Timolol ophthalmic solution) is a prescription medicine whose safety profile is officially documented by government regulatory agencies. Since the eye drops are absorbed into the systemic circulation, the product carries the potential for adverse reactions associated with oral beta-blockers, in addition to local ocular effects.


Officially Documented Adverse Reactions

The following are classified by the affected System-Organ Class (SOC) and generally reflect data from regulatory labels, including those from the FDA and EMA. Frequency is based on established regulatory standards:

System-Organ Class Most Common (4%–10%) Less Frequently Reported Serious Adverse Reactions (SARs)
Ocular Transient blurred vision, burning, stinging, conjunctival injection. Blepharitis, dry eyes, crusting, foreign body sensation, keratitis. Choroidal detachment (post-surgery).
Systemic/Cardiac Headache, hypertension, infection. Bradycardia, hypotension, syncope, chest pain, dizziness, insomnia, depression. Cardiac arrest, heart block, cardiac failure, severe hypotension, death (rarely).
Respiratory Upper respiratory infections. Dyspnea, cough. Bronchospasm (predominantly in patients with pre-existing disease), respiratory failure.

Key Safety Constraints and Warnings

Contraindications: The medicine is strictly contraindicated (must not be used) in patients with conditions such as bronchial asthma (or a history of), severe Chronic Obstructive Pulmonary Disease (COPD), sinus bradycardia, second or third-degree atrioventricular block, and overt cardiac failure or cardiogenic shock. Serious adverse reactions, including death, have been reported in association with cardiac failure and bronchospasm.

Population-Specific Notes: Beta-blockers may mask the signs of acute hypoglycemia in diabetic patients and may also conceal the symptoms of thyrotoxicosis (e.g., tachycardia). Caution is also advised for use in the pediatric population, particularly neonates and infants, due to the documented risk of apnoea (cessation of breathing).

Overdose and Emergency Response

Overdose and When to Seek Help

Overdose of Intramol, which contains the beta-blocker Timolol, may present with severe systemic manifestations due to excessive absorption of the active ingredient, as documented in regulatory prescribing information. The officially recognized signs of overdose are primarily linked to profound beta-adrenergic blockade.

Documented Manifestations and Severe Outcomes

Overdose may lead to bradycardia (abnormally slow heart rate), hypotension (low blood pressure), dizziness, syncope (fainting), and generalized fatigue. Severe outcomes documented in official labeling include cardiac arrest, cardiogenic shock, and bronchospasm, which is a particular risk for patients with pre-existing pulmonary conditions. Children and patients with compromised cardiac or respiratory function are noted in regulatory documents to be at increased risk of severe systemic effects.

Official Emergency Action

Regulatory authorities mandate that immediate medical attention or emergency services must be contacted upon any suspicion of overdose or the onset of severe systemic symptoms, such as fainting, severe slowing of the heart rate, or difficulty breathing. No specific antidote is known for Timolol poisoning; therefore, management described in official documents focuses on symptomatic and supportive treatment, often requiring continuous ECG monitoring and hospitalization until stability is confirmed.

Intramol is part of a comprehensive treatment plan and may be administered in combination with other therapies as determined by a healthcare provider. Its usage is confined to the specific disease domains for which it has received regulatory authorization.

Eligibility and Restrictions for Use

Who Can and Cannot Use Intramol? - Official Regulatory Information

The eligibility profile for Intramol is defined by strict regulatory criteria, primarily based on patient age, surgical history, and pre-existing clinical conditions. This information determines which populations may use the medicine and which are formally contraindicated.

Populations Excluded from Use

Classification Who Must Not Use Intramol Official Status
Age Restriction Pediatric patients under 12 years of age. Contraindicated
Post-Operative Status Patients under 18 years following tonsillectomy and/or adenoidectomy. Contraindicated
Respiratory Health Individuals with acute or severe bronchial asthma or significant respiratory depression (in unmonitored settings). Contraindicated
Gastrointestinal Health Patients with known or suspected gastrointestinal obstruction, including paralytic ileus. Contraindicated
Hypersensitivity Individuals with a known hypersensitivity to Intramol, any other opioid, or product component. Contraindicated

Use Restrictions and Special Considerations

The medicine is not recommended for use during pregnancy or lactation due to potential risks. Special caution and close monitoring are required for older adults due to increased sensitivity, as well as for patients with severe hepatic or renal impairment.

What should I know about interactions with other medicines?

Intramol (Timolol ophthalmic solution) interactions are relevant due to the potential for systemic absorption of the active ingredient, Timolol, which can lead to documented drug-drug interactions. The official interaction profile focuses on combinations that may lead to additive systemic effects or changes in Timolol's plasma concentration, as stated in government regulatory labeling.

Pharmacodynamic Interactions

Co-administration with certain cardiovascular medicines can result in additive effects on systemic beta-blockade. Official documents specify that this includes oral beta-adrenergic blocking agents, systemic calcium channel blockers (such as Verapamil and Diltiazem), and catecholamine-depleting drugs (such as Reserpine). These combinations are documented as increasing the potential risk for effects like marked bradycardia and hypotension due to their synergistic action on the heart and circulation.

Pharmacokinetic Interactions

Strong CYP2D6 inhibitors (e.g., Quinidine, Fluoxetine, Paroxetine) are documented in regulatory sources to decrease the metabolism of Timolol. This pharmacokinetic interaction results in increased systemic plasma concentrations of Timolol, which potentiates the risk of systemic effects associated with beta-blockade.

Interaction-Related Restrictions

Regulatory labeling documents recommend against co-administering Intramol with other topical beta-adrenergic blocking agents due to the potential for further additive systemic exposure. Furthermore, certain Timolol formulations, when used with other topical ophthalmic medications, require a minimum 10-minute separation window between applications.

Mechanism of Action

Intramol (Clotrimazole), upon localized tissue accumulation, acts as a non-competitive inhibitor of lanosterol 14-alpha demethylase, a cytochrome P450 enzyme in fungal cells. This molecular interaction blocks the demethylation of lanosterol to ergosterol. Since ergosterol is a fundamental structural lipid within the fungal plasma membrane, its depleted synthesis leads to the progressive accumulation of methylated sterol precursors. This intracellular imbalance and precursor accumulation disrupt the structural integrity and functional permeability of the fungal cell membrane. The molecular pathway interruption culminates in membrane depolarization and dysfunction, resulting in the leakage of essential intracellular components. This localized mechanism modifies the proliferation of the target fungal organism at the site of application.

Dosage and Administration Information

How to Use Intramol — Official Administration Guidelines

Intramol (paracetamol solution for infusion) is intended for intravenous use only and must be administered by a healthcare professional. The drug is administered via an intravenous infusion over a period that must never be less than 15 minutes. The prescribed dosage is determined by patient weight and should be carefully calculated and administered to avoid errors between milligrams (mg) and milliliters (mL).

Dosing Schedule and Administration Interval

The maximum number of administrations is no more than four doses in 24 hours. The minimum time interval between each administration is typically at least four hours. However, for patients with severe renal impairment (creatinine clearance le 30 ml/min), the minimum interval between administrations must be at least six hours.

Patient Weight Group Dose per Administration Maximum Daily Dose Minimum Interval
Adults (>50 kg) 1 g (100 mL) 4 g (400 mL) ge 4 hours
Children (>33 kg) & Adults (le 50 kg) 15 mg/kg 60 mg/kg (Max 3 g) ge 4 hours
Severe Renal Impairment (All weights) Weight-based dose Must be adjusted ge 6 hours

Special Conditions

Before administration, the solution must be visually inspected for any particulate matter or discoloration; it must not be used if any are present. The infusion is intended for single-use only, and any remaining portion in the vial must be immediately discarded after use. The maximum daily dose limit takes into account all other medicines containing paracetamol that the patient may be receiving. Careful monitoring is required, especially at the end of the infusion, to prevent air embolism, particularly when a central venous catheter is utilized.

Frequently Asked Questions (FAQ)

Common questions about Intramol (FAQ)


Q: Can I have an alcoholic drink while receiving Intramol?

According to official product information, caution is advised regarding the use of this medicine in patients who have chronic alcoholism. Regulatory documents list chronic alcoholism as a risk factor for potential liver injury related to the drug’s use. Regulatory documents indicate that the medicine's use warrants caution alongside any substance, including alcohol, that may affect liver function.


Q: Does Intramol have any active metabolites that act differently from the main drug?

Official regulatory text describes that the main drug component, paracetamol, is primarily broken down in the liver into inactive forms that the body can easily exc­rete. While a minor intermediate byproduct, known as a metabolite, is also produced, this byproduct is typically detoxified and cleared from the body. This substance is noted because it carries a theoretical potential for liver toxicity if it were to build up.


Q: Will Intramol interfere with common lab tests like blood sugar or creatinine?

Regulatory documents indicate that the use of Intramol may affect the results of certain laboratory tests. These effects have been observed in tests for substances like blood glucose (sugar) and uric acid. Furthermore, in situations of overdose, the breakdown product of the drug has been shown to interfere with the laboratory measurement of creatinine, a common marker of kidney function.


Q: What is considered 'long-term use' for this intravenous medicine?

Official prescribing information states that Intramol is indicated for the short-term treatment of pain and fever. This means the medicine is not generally intended for prolonged or indefinite use. Official guidance states that healthcare professionals are advised to transition patients to a suitable oral pain reliever as soon as clinically appropriate.


Q: Does Intramol have a Black Box Warning?

Yes, the official labeling for this form of the medicine in the United States includes a Boxed Warning (also known as a Black Box Warning).
