What is Acefyl Syrup? An Overview
Acefyl Syrup
Acefyl Syrup is a bronchodilator medication used to treat cough and breathing difficulties caused by conditions like asthma and bronchitis. It contains Acefylline, which works by relaxing the airways in the lungs to make breathing easier.

Acefyl Syrup is a popular prescription medication in Pakistan belonging to the class of drugs known as bronchodilators. It is primarily used to treat and manage symptoms associated with obstructive airway diseases. The therapeutic effects of this syrup make it a go-to choice for physicians when dealing with persistent cough and breathing difficulties.
What is the active ingredient in Acefyl Syrup?
The active ingredient in Acefyl Syrup is Acefylline, which is a derivative of Theophylline, a methylxanthine compound. Acefylline works differently from typical antihistamine or suppressant cough syrups, targeting the underlying physiological mechanisms that cause airway constriction rather than simply suppressing the cough reflex. This fundamental difference makes it particularly effective for specific types of respiratory distress.
- Pharmaceutical Class: Methylxanthine derivative
- Chemical Structure: Similar to Theophylline but with different pharmacokinetic properties
- Primary Action: Bronchodilation and respiratory stimulation
What is the mechanism of action of Acefylline?
Acefylline operates through multiple pharmacological pathways to relieve respiratory symptoms. Understanding its mechanism of action explains why it’s prescribed for specific conditions and not for every type of cough.
- Phosphodiesterase Inhibition: Acefylline blocks the enzyme phosphodiesterase, leading to increased cyclic AMP levels, which promotes relaxation of bronchial smooth muscles
- Adenosine Receptor Antagonism: By blocking adenosine receptors, it prevents bronchoconstriction that would otherwise narrow airways
- Respiratory Stimulation: It enhances the contractility of diaphragmatic muscles, improving respiratory drive and efficiency
- Mucociliary Clearance: The drug helps in increasing the movement of cilia in the respiratory tract, facilitating the removal of mucus and secretions
Common brand names and manufacturers in Pakistan
Acefyl Syrup is manufactured by multiple pharmaceutical companies in Pakistan, with some variations in brand names and formulations. The most common manufacturers include:
- Bosch Pharmaceutical (Pakistan)
- S.J. & G. Fazul Ellahie
- Saydon Pharmaceutical
- Pharmix Pharmaceutical
Different brands may offer the syrup in varying concentrations, with Acefyl 125 containing a higher strength of the active ingredient compared to standard Acefyl syrup.
Primary Uses and Benefits of Acefyl Syrup
Acefyl Syrup is prescribed for specific respiratory conditions where airway obstruction is a primary concern. Its therapeutic benefits extend beyond simple cough suppression, addressing the root cause of breathing difficulties in obstructive lung diseases.
What is Acefylline used for?
Acefylline has several established medical applications based on its pharmacological properties as a bronchodilator and respiratory stimulant. Physicians prescribe it for:
- Bronchial Asthma: For both acute attacks and chronic management of reversible airway obstruction
- Chronic Bronchitis: To alleviate symptoms of inflammation and mucus production in the airways
- Emphysema: As part of comprehensive management for this obstructive lung disease
- COPD: Chronic Obstructive Pulmonary Disease management where airway constriction is present
- Bronchiectasis: To improve airway clearance in this chronic condition characterized by damaged airways
Is Acefyl Syrup for dry cough or wet cough?
Acefyl Syrup is effective for both dry and wet coughs, but its mechanism works best when bronchospasm is involved in the cough reflex. The classification depends on the underlying cause:
- Dry Cough: Effective when the dry cough results from bronchial constriction or irritation
- Wet Cough: Helps by improving mucus clearance through enhanced ciliary action and bronchodilation
- Spasmodic Cough: Particularly effective for coughs with a spasmodic or wheezing component
Acefyl syrup uses for babies and children
Pediatric use of Acefyl Syrup requires extreme caution and strict medical supervision. In children, it may be prescribed for:
- Asthmatic Bronchitis: When children present with wheezing and breathing difficulties
- Bronchiolitis: As part of a comprehensive treatment plan under hospital supervision
- Exercise-Induced Bronchospasm: For prevention and management in school-aged children
- Viral-Associated Wheeze: For symptomatic relief during respiratory infections
