ABSTRACT:

Asthenopia, commonly known as eye strain, is a condition characterized by a group of subjective symptoms such as ocular fatigue, eye discomfort, lacrimation (excessive tearing), headaches, blurred vision, photophobia (light sensitivity) and difficulty in maintaining visual focus over extended periods. These symptoms frequently develop due to prolonged visual activities, including reading, screen exposure and tasks that demand intense eye concentration. With the increasing reliance on digital devices in daily life, the prevalence of asthenopia has risen significantly, highlighting the need for effective preventive and therapeutic strategies. In recent years, interest has grown in the application of plant-based remedies for ocular health. Herba Taraxaci (commonly known as dandelion) has been recognized for its anti-inflammatory and soothing properties, suggesting its potential in managing visual fatigue. This natural extract may offer protective benefits for the ocular system by reducing inflammation and alleviating the discomfort associated with extended visual tasks. To enhance patient compliance and promote ease of administration, especially for routine use, formulations such as chewable gummies have been explored. These delivery systems are particularly advantageous for individuals seeking non-invasive, convenient options for eye care. Furthermore, ophthalmic formulations containing dandelion extract present a promising for both the prevention and treatment of asthenopia, reflecting a novel approach to ocular therapy through natural, plant-derived ingredients.

 

KEYWORDS: Asthenopia Syndrome, Anti-Inflammatory, Chewable Gummies, Herba Taraxaci Extract.

 

 


INTRODUCTION: 

Drugs or molecules that are pharmacologically active are often manufactured into a range of dosage forms, such as tablets, capsules, injectables, inhalers, ointments and more. This formulation method considers a number of essential variables, including the drug's physicochemical characteristics, pharmacokinetic and pharmacodynamic parameters and different biopharmaceutical elements.1,2,3

 

Every dose form is made to maximize medication distribution and accomplish the intended therapeutic outcome. Interestingly, chewable gummies has shown to be an important delivery system for pharmacological and nutraceutical compounds, going beyond its customary use as a confection. When it comes to medicine distribution, chewable gummies has different advantages, particularly for some kinds of drugs. Chewing promotes medication release and absorption4, the oral administration offers a practical and non-invasive method for administration. Furthermore, there are advantages in using chewing gum as a medication delivery process, namely bypassing first-pass metabolism and offering a faster onset of effect5. Chewing gum's ability to operate as both a confection and a method of administration for pharmaceutical or nutraceutical substances highlights its promise as a novel and patient-friendly dosage form6. An interesting field of pharmaceutical research is devoted to the development of chewing gum, formulations for medication administration with the goal of enhancing patient compliance and overall treatment success. Chewing gum evolved into a practical and adaptable delivery method that may be used with a wide range of active ingredients. A number of medicinal drugs can be conveniently ingested through the oral mucosa. When compared to conventional oral dose forms, formulations such as chewable gummies, chewable tablets and lozenges can provide speedier therapeutic action for medicines that demonstrate considerable buccal absorption7,8,9 Among parents, chewable pills and chewing gum are particularly liked for giving medication to kids whose teeth have properly grown.

 

The simplicity of usage and possible rise in patient compliance are what make it appealing. When compared to oral liquids and standard pills, chewable gummies may be a more convenient way for children in particular to take medicines. This inclination could be explained by the fact that chewing is a more pleasant habit for young people and chewing gum is sweeter.10

 

Consequently, then application of chewable gummies as a medicine delivery method enhances patient satisfaction and therapeutic efficacy, especially in case of younger patients. Chewable gummies with treatment has been shown to be a practical therapeutic option for both systemic and localized illnesses of the oral cavity. These chewable gummies with medicines are single-dose, solid formulations with a gum base that is meant to be chewed rather than ingested. They include one or more active substances in their formulation, which are released during chewing. These medicated chewable gummies are designed to serve two distinct roles: first, they may be used to treat oral disorders locally, directly addressing issues that arise in the mouth; second, they can help with systemic distribution by promoting absorption via the buccal mucosa. This drug delivery approach combines both local and systemic medicinal benefits11, providing a novel and efficient means of medicine dosage. Herba Taraxaci extract is used in anti-inflammatory chewable gummies for preventing or treating the purposes of the syndromic pharmaceutical composition of asthenopia in preparation. Pharmacological investigations have revealed that Taraxacum crude extracts and chemical compounds contain antimicrobial infection, anti-inflammatory, anti-tumor, anti-oxidative properties. Taraxacum’s anti-inflammatory mechanism may be connected to its capacity to decrease the mRNA expression of inflammatory factors in a dose dependant manner. Taraxasterol could exert anti-inflammatory effects by regulating the phosphorylation levels of p38 and ERK1/2 MAPKs and by inhibiting the expression of inducible nitrous oxide synthase (iNOS) and cyclooxygenase-2 (COX-2).12

 

Advantages:

Chewable gummies offer several advantages that enhance patient acceptability and treatment effectiveness. Their convenient and portable format promotes higher patient compliance, especially since they do not require water for administration. This makes them ideal for use. They are particularly suitable for individuals with swallowing difficulties, such as the elderly or those with certain medical conditions. The pleasant taste of gummies further improves the patient experience, especially when compared to unpleasant-tasting traditional dosage forms. Additionally, chewing stimulates saliva production, which helps in preventing dry mouth and related conditions like oral candidiasis. Another key benefit is the quicker onset of action due to increased surface area and faster drug disintegration during chewing.13

 

Disadvantages:

There are some disadvantages. Ensuring uniformity in the drug content of each gummy can be technically challenging, which is critical for safe and effective dosing.14 The gum base is hygroscopic, meaning it can absorb moisture from the environment, potentially compromising product stability over time. Furthermore, this dosage form is not suitable for medications that require high doses, as it may be difficult to incorporate large quantities of active ingredients into a single gummy15.

 

Materials:

Taraxaci Extract obtained form leaves of taraxaci plant, Gelatin, Hydroxypropyl Methylcellulose, Sucrose, Polysorbate 80, Polaxamer 188, Citric Acid, Orrange Essensce, Purified Water.

METHOD:

Extraction Procedure:

The dried plant material was extracted by reflux using 70% ethanol as the solvent, maintaining a solid-to-liquid ratio of 1:20. This extraction process was carried out for 3 hours at a temperature of 80°C to ensure efficient extraction of the desired compounds.16 Following extraction, the mixture was filtered through cellulose filter paper to remove solid residues and obtain a clear filtrate. The obtained filtrate was then concentrated using a rotary evaporator under reduced pressure at 45°C to gently remove the ethanol solvent without degrading the extract components. After concentration, the extract was dried using refrigeration methods to obtain a stable dry powder.17 The overall extraction process yielded 24.7% of the powdered extract relative to the initial weight of the dried plant material.18,19,20
