Dental Diseases

In the present day circumstances, it has been reported that the Dental diseases are a most important physical condition problem in all parts of the globe, general in all age groups, races and genders. The proportion of dental diseases has developed to a great extent in current years. Around 70% of inhabitants suffer from dental problems. The human population is exaggerated by foremost of oral diseases. To treat dental problems such as pain due to dental caries, periodonitis, gingivitis, and other gum infections, painkillers alongside with antibiotics and various dental paints are the generally prescribed drugs by dentists as primary mode of treatment. However the general side effects of most of the painkillers are hyperacidity and gastric annoyance upon oral administration. On the other hand, nearly all antibiotics due to measured onset of action and hepatic “first-pass” consequence fail to construct prompt and extend actions. Furthermore, most of the dental formulations are washed out by saliva inside a few hours of application. To conquer the above-mentioned problems, a soft polymeric mold containing antibiotic and anasthetics drugs and having a suitable constancy to stick to the tooth, was developed for continued drug release to endow with improved relief in dental patients. Carbopol 934, Ethyl cellulose, Gum tragacanth, Hydroxy propyl cellulose, and PEG 400 were used to organize the formulation containing Lidocaine hydrochloride and doxycycline hyclate individually and in combination, by addition and solvent evaporation technique. Dissimilar physicochemical characterization studies such as mucoadhesion test and swelling index were conceded out. In vitro drug release studies showed sustained release of Lidocaine hydrochloride and doxycycline hyclate in simulated saliva for 24 h. Additional studies are necessary to succeed with these formulations in humans. Upon accomplishment, this type of dosage form may open up new avenues towards dentistry.

The present work is aimed to formulate the tablets containing fenugreek extract as drug by wet granulation method. Further the effect of Sodium Starch Glycolate as super disintegrant on disintegration and drug release was studied. Fenugreek extract contains mucilage which retards the disintegration of tablets and hence shows slower drug release. Hence in order to improve disintegration and thereby in vitro drug release, Sodium Starch Glycolate was used as super disintegrant. Tablet formulations were prepared without the SSG (Conventional-F1) and also with sodium starch glycolate (F2-F4) by wet granulation method. Assessment of flow properties of granules, physicochemical characterization of tablet formulations was carried out. Fenugreek is widely used for its antidiabetic activity which is attributed to mainly to the presence of an alkaloid Trigonelline. Hence in vitro release study of trigonelline was carried out which showed that the percentage release from F1 and F2 was found to be 58.12±4.49 and 99.08±0.01 respectively after 6 hrs. This study concludes that tablet formulation of fenugreek seed extracts with super disintegrants will be more desirable, advantageous and therapeutically more beneficial than incorporating the direct plant materials for the treatment of diabetes for faster onset of action.

Fast dissolving oral delivery systems are solid dosage forms, which disintegrate or dissolve within 1 minute in the mouth without drinking water or chewing. Mouth dissolving film (MDF) is a better alternate to oral disintegrating tablets due to its novelty, ease of use and the consequent patient compliance. The purpose of this work was to develop mouth dissolving oral films of palonosetron HCl, an antiemetic drug especially used in the prevention and treatment of chemotherapy-induced nausea and vomiting. In the present work, the films were prepared by using solvent casting method with various polymers HPMC E3, E5 & E15 as a film base synthetic polymer, propylene glycol as a plasticizer and maltodextrin and other polymers. Films were found to be satisfactory when evaluated for thickness, in vitro drug release, folding endurance, drug content and disintegration time. The surface pH of all the films was found to be neutral. The in vitro drug release of optimized formulation F29 was found to be 99.55 ± 6.3 7% in 7 min. The optimized formulation F29 also showed satisfactory surface pH, drug content (99.38 ± 0.08 %), disintegration time of 8 seconds and good stability. FTIR data revealed that no interaction takes place between the drug and polymers used in the optimized formulation. In vitro and in vivo evaluation of the films confirmed their potential as an innovative dosage form to improve delivery and quick onset of action of Palonosetron Hydrochloride. Therefore, the mouth dissolving film of palonosetron is potentially useful for the treatment of emesis disease where quick onset of action is desired, also improved patient compliance.

Purpose: In the current study, electrospraying was directed as a novel alternative approach to improve the physicochemical attributes of gliclazide (GLC), as a poorly water-soluble drug, by creating nanocrystalline/amorphous solid dispersions (ESSs). Methods: ESSs were formulated using Eudragit® RS100 and polyethylene glycol (PEG) 6000 as polymeric carriers at various drug: polymer ratios (i.e. 1:5 and 1:10) with different total solution concentrations of 10, 15, and 20% w/v. Morphological, physicochemical, and in-vitro release characteristics of the developed formulations were assessed. Furthermore, GLC dissolution behaviors from ESSs were fitted to various models in order to realize the drug release mechanism. Results: Field emission scanning electron microscopy analyses revealed that the size and morphology of the ESSs were affected by the drug: polymer ratios and solution concentrations. The polymer ratio augmentation led to increase in the particle size while the solution concentration enhancement yielded in a fiber establishment. Differential scanning calorimetry and powder X-ray diffraction investigations demonstrated that the ESSs were present in an amorphous state. Furthermore, the in vitro drug release studies depicted that the samples prepared employing PEG 6000 as carrier enhanced the dissolution rate and the model that appropriately fitted the release behavior of ESSs was Weibull model, where demonstrating a Fickian diffusion as the leading release mechanism. Fourier-transform infrared spectroscopy results showed a probability of complexation or hydrogen bonding, development between GLC and the polymers in the solid state. Conclusion: Hence the electrospraying system avails the both nanosizing and amorphization advantages, therefore, it can be efficiently applied to formulating of ESSs of BCS Class II drugs.

Objective: The present investigation was aimed at preparation and evaluation of mouth dissolving films (MDFs) of Ramipril to enhance patient convenience, compliance and to improve bioavailability. Methods: MDFs with 0.5% w/w Ramipril were prepared by a solvent casting method using a wet film applicator. The effects of film formers, wetting/solubilizing, saliva stimulating agents and film modifiers on the physicomechanical and in vitro Ramipril release from MDFs were evaluated. Results: The MDFs prepared were transparent, smooth and showed no re-crystallization upon storage. MDFs casted with hydroxypropyl methylcellulose (HPMC) E3 as film former and polyethylene glycol (PEG-400) as plasticizer showed superior Ramipril release rates and good physicomechanical properties when compared to MDFs with E5 and E15 as film formers. HPMC E3 MDFs with polyvinyl pyrrolidone K30 (PVP K30) and sodium lauryl sulphate (SLS) gave superior drug release properties than MDFs without PVP K30 and SLS. The HPMC E3 MDFs with citric acid (CA) as saliva stimulating and xylitol as soothing agent gave significantly superior in vitro drug release than the MDFs without CA and xylitol. Release kinetics data reveals diffusion as a drug release mechanism. Conclusion: From the obtained results, it can be concluded that the administration of Ramipril as MDF may provide a quick onset of action with enhanced oral bioavailability and therapeutic efficacy.

BACKGROUND: The study of dental problems characteristic of geriatric patients is becoming increasingly relevant. As a person ages, the entire dental system undergoes physiological and functional changes. To eliminate the adverse effects of oral diseases, prolong the period of remission, preventive measures, constant monitoring of the level of hygiene, dispensary supervision of elderly and senile persons are necessary. AIM: This study aimed to determine the prevalence and intensity of dental diseases in the following older age groups: young elderly (6574 years old), old elderly (7584 years old), and very old elderly (85 years old and older). MATERIALS AND METHODS: A dental examination of 183 patients was carried out using a modified card for assessing the state of the dental status, according to guidelines of the World Health Organization. RESULTS: Analysis of dental morbidity in the older age group showed that the most common dental diseases in this group were extractions of lossened teeth caused by caries and periodontal diseases. Following a comprehensive dental examination of elderly patients and people with senility, the intensity of KPU and OHI-S was 19.760.52 and 2.710.12, respec-tively, and this indicates the poor hygienic state of the oral cavity of this population. CONCLUSION: Data support the untimeliness and inadequacy of dental care in elderly patients and people with senility. This necessitates the development of special treatment and prophylactic programs for this population, aimed at reducing dental morbidity.
