This study presents the formulation of herbal lozenges using a heating and congealing technique. A thorough literature review informed the selection of excipients, which included Agar, Acacia, peppermint oil, citric acid, glycerin, PEG 1000, and PEG 8000. The lozenges were evaluated for weight variation, hardness, thickness, friability, disintegration time, and drug content, with all parameters meeting standard limits. Among the formulations, F6 demonstrated the highest drug content at 99.35%. The study concluded that the herbal lozenges, particularly those incorporating agar and acacia, are a promising therapeutic option for treating mouth and throat infections and enhancing immunity in patients. Stability studies were also conducted to ensure the formulation's viability.
Solid dosage forms are highly favored for oral drug delivery due to their ease of administration, accurate dosage, and patient compliance. Tablets, in particular, are widely accepted because they allow for self-medication and help in avoiding pain. Many patients face challenges when it comes to swallowing conventional tablet dosage forms, especially when water is not readily available. Dispersible tablet delivery systems offer a solution with their fast disintegration, quick dissolving, rapid release, and improved patient compliance. This difficulty in swallowing, known as dysphagia, affects people of all age groups, particularly the elderly and pediatrics, due to physiological changes associated with these groups. In certain cases, individuals facing challenges with traditional oral medications include those with mental health issues, uncooperative behavior, and patients dealing with symptoms like nausea, motion sickness, sudden allergic reactions, or frequent coughing. Additionally, the absence of water can make it tough to consume conventional products. These difficulties have driven the creation of a new type of solid oral medication. As a result, there is a growing need for appealing formulations that effectively mask taste. When it comes to lozenges, they can contain a variety of drugs such as pain relievers, anesthetics, antimicrobials, antiseptics, cough suppressants, aromatic compounds, astringents, corticosteroids, decongestants, and soothing agents. Sore throats, mouth sores, and other irritations in the mouth and throat are common issues that can be quite painful. While there are many pharmaceutical options available, both over-the-counter and prescription, for treating this pain, it can be challenging to administer these drugs to patients who are unwilling or unable to take traditional oral medications. For instance, both children and adults might struggle to swallow tablets or capsules.

The skin contained a higher concentration of cellulose (10%) and hemicellulose (13%) compared to the pulp, which only had 1.4?llulose and 1.3% hemicellulose. Additionally, the pulp protein was notably abundant in arginine, aspartic acid, and glutamic acid. Methionine was present in the lowest amount, while tryptophan and cystine were conspicuously absent.

3.2.1. Extraction From Plantain Banana:
The peel of the plantain banana was collected and dried for some time. Then the peel is cut into small pieces as appropriate for the efficient extraction of chemical constituents. In the process of extraction the cutted pieces of banana peel is placed in stoppered container with the ethanol as a solvent and allowed to stand at room temperature for a period of at least 3 days with frequent agitation untill the soluble matter has dissolved. The mixture is then strained, the Marc is pressed, and the combined liquids are clarified by filtration after standing.
3.2.2. Extraction From Cynodon Dactylon:
The method of extraction is Maceration. The durva grass is washed with water. Then cut into small pieces as appropriate. In the process of Maceration the cutted pieces of durva grass is placed in a stoppered container with the ethanol as a solvent and allowed to stand at room temperature for a period of at least 3 days with frequent agitation untill the soluble matter has dissolved. The mixture is then strained and the Marc is pressed, the combined liquids are clarified by filtration after standing.

Table: 3 Composition Of Herbal Lozenges
PROCEDURE:
Herbal lozenges were prepared by heating and congealing technique. base was prepared by dissolving required amounts of water while heating it and stirring continuously for 60 min at the temperature of 90?C. polymers was added to the base to prevent crystallization of base, and the base was heated and stirred continuously till a plastic mass was obtained. The temperature was brought down to 40?C and to the plastic mass, drug dispersed in base, preservative, colour and flavor were added and the material was stirred for 20min. Then the mixture was poured in to desire molds and air dried for 1hr.
3.5. Evaluation Of Herbal Lozenges:
3.5.1. Physical Parameter:
The general appearance of a lozenges including size, shape, colour, odour, taste having should be observed. It is must to have a good appearance for consumer acceptance. Physical changes may occur during storage, which can be determined PH using PH meter apparatus.
3.5.2. Thickness:
The thickness and diameter of the formulated lozenges were measured by using Vernier callipers.
3.5.3. Diameter:
The thickness and diameter of lozenges were determined using vernier callipers. [Three lozenges from each batch were used and average values were calculated. The extent to which the diameter of the lozenges deviated from ± 5 % of the standard value.
3.5.4. Weight Variation:
The formulated lozenges were tested for weight uniformity. 10 lozenges were collectively and individually. From the collective weight, average weight was calculated. Each lozenges weight was then compared with average weight to ascertain whether it is with in permissible limits or not.
3.5.5. Hardness:
The lozenges crushing strength, which is the force required to break the lozenges by compression in the diametric direction was measured in triplicate using Pfizer tablet hardness tester or Monsanto hardness tester.
3.5.6. Friability:
The Roche friability test apparatus was used to determine the friability of the lozenges. 5 pre-weighed lozenges were placed in the apparatus, which was subjected to 100 revolutions. Then the lozenges were reweighed.
3.5.7. Moisture Content:
The sample was weighed and crushed in a mortar. From this, one gram of the sample was weighed and placed in desiccators for 24 hours. After 24 hours the sample is weighed. The moisture content is determined by the abstracting the final weight from initial weight of lozenges.
3.5.8. Disintegration Test:
Disintegration study performed by disintegration apparatus. Put one lozenges into each tube suspend the assembly in the beaker containing pH 7.1 phosphate buffer and operate without the discs 30 min. Remove the assembly from the liquid. The Herbal lozenges pass.
3.5.9. Drug Content:
Drug content is done by taking an appropriate number of lozenges being crushed and dissolved in a suitable solvent and the absorbance of the solution is measured spectrophotometrically. Weighed 10 gm of each lozenges formulation were transferred in 250 ml of the volumetric flask containing 20 ml of Phosphate buffer 7.1 and stirred. The volume was made up to 100 ml and filtered. 1 ml of the above solution was further diluted to 10 ml with Phosphate buffer 7.1 and again 1 ml of the above solution was further diluted to 10 ml with Phosphate buffer 7.1. The absorbance of the solution was measured spectrophotometrically at 224 nm. Drug content was calculated by the following formula
Drug content=absorbanceslope × Dilution factor ×11000
3.5.10. Sensory Evaluation:
Sensory evaluation of lozenges was done, following parameters were considered like color, taste, flavor, consistency and overall acceptability. On the basis of this evaluation following results came out.
3.5.11. Stability studies:
As per ICH guidelines stability studies were conducted for selected formulation and it was observed that there was no significant change in the physical appearance and in the physicochemical characteristics of selected formulation.
3.5.12. Feed Back Data:
The data of prepared lozenges without Drug in Healthy Human Volunteers to collect the feed back information.
