Description

DERIPHYLLIN RETARD 150 MG (1X30)

Indications

Deriphyllin Retard 150 mg is a medication primarily indicated for the treatment of chronic obstructive pulmonary disease (COPD) and asthma. It is used to relieve symptoms associated with bronchial asthma and other respiratory conditions characterized by bronchospasm. This medication is particularly beneficial for patients experiencing difficulty in breathing due to constricted airways, providing symptomatic relief and improving overall pulmonary function.

Mechanism of Action

Deriphyllin, the active ingredient in Deriphyllin Retard, is a xanthine derivative that primarily acts as a bronchodilator. It works by inhibiting the enzyme phosphodiesterase, which leads to an increase in intracellular cyclic adenosine monophosphate (cAMP) levels. The elevation of cAMP results in relaxation of bronchial smooth muscles, thereby dilating the airways and facilitating easier airflow. Additionally, Deriphyllin exhibits anti-inflammatory properties that help reduce airway inflammation, further aiding in the management of respiratory conditions.

Pharmacological Properties

Deriphyllin Retard has several pharmacological properties that contribute to its effectiveness in treating respiratory disorders. The prolonged-release formulation of Deriphyllin ensures a sustained therapeutic effect, allowing for less frequent dosing. The drug is well-absorbed after oral administration, with peak plasma concentrations typically reached within 2 to 4 hours. Its half-life ranges from 6 to 12 hours, depending on individual metabolic factors. Deriphyllin is primarily metabolized in the liver and excreted through the kidneys, necessitating caution in patients with hepatic or renal impairment.

Contraindications

Deriphyllin Retard is contraindicated in patients with a known hypersensitivity to the active substance or any of the excipients in the formulation. It should not be used in individuals with severe cardiac arrhythmias, uncontrolled hyperthyroidism, or peptic ulcer disease. Caution is advised when prescribing this medication to patients with a history of seizures or those taking other medications that may interact with the pharmacokinetics of Deriphyllin.

Side Effects

Like all medications, Deriphyllin Retard may cause side effects. Common side effects include gastrointestinal disturbances such as nausea, vomiting, and diarrhea. Patients may also experience central nervous system effects like headache, insomnia, and restlessness. In rare cases, more severe side effects such as tachycardia, palpitations, and hypotension may occur. Patients should be advised to report any unusual symptoms or severe side effects to their healthcare provider promptly.

Dosage and Administration

The recommended dosage of Deriphyllin Retard for adults is typically one tablet of 150 mg taken orally, twice daily. It is advisable to take the medication at the same times each day to maintain consistent blood levels. The tablets should be swallowed whole with a sufficient amount of water and should not be crushed or chewed to ensure proper release of the active ingredient. Dosage adjustments may be necessary for elderly patients or those with hepatic or renal impairment, and such adjustments should be guided by a healthcare professional.

Interactions

Deriphyllin Retard may interact with various medications, potentially altering their effectiveness or increasing the risk of adverse effects. It is important to inform healthcare providers about all medications currently being taken, including over-the-counter drugs and herbal supplements. Notable interactions include those with other xanthine derivatives, beta-adrenergic agonists, and certain antibiotics such as erythromycin and ciprofloxacin, which may increase the plasma concentration of Deriphyllin. Additionally, medications that affect liver enzymes may alter the metabolism of Deriphyllin, necessitating careful monitoring and possible dosage adjustments.

Precautions

Before initiating treatment with Deriphyllin Retard, a thorough medical history should be obtained, and a physical examination should be conducted. Patients with pre-existing conditions such as cardiovascular disease, hyperthyroidism, or a history of seizures should be monitored closely during treatment. It is also essential to assess the patient’s response to the medication regularly, adjusting the treatment plan as necessary. Pregnant or breastfeeding women should consult their healthcare provider before using this medication, as the safety of Deriphyllin in these populations has not been fully established.

Clinical Studies

Clinical studies have demonstrated the efficacy of Deriphyllin Retard in improving pulmonary function and reducing symptoms in patients with COPD and asthma. In a randomized controlled trial, patients receiving Deriphyllin showed significant improvements in forced expiratory volume (FEV1) and peak expiratory flow rate (PEFR) compared to those receiving a placebo. Additionally, the sustained-release formulation was associated with improved patient adherence due to the reduced frequency of dosing. These findings support the use of Deriphyllin Retard as an effective therapeutic option for managing chronic respiratory conditions.

Conclusion

Deriphyllin Retard 150 mg is a valuable medication for the management of chronic obstructive pulmonary disease and asthma. Its bronchodilator effects, combined with a sustained-release formulation, make it an effective choice for patients requiring long-term management of their respiratory symptoms. However, it is crucial for patients to be aware of potential side effects and drug interactions, and to use this medication under the guidance of a healthcare professional. Regular monitoring and follow-up are essential to ensure optimal therapeutic outcomes and patient safety.
