Inter Molecular Level Interaction Studies of Combination Drug Crizotinib And Temozolomide in Glioblastoma Multiforme Targets: An In-silico Approach

Combination drug treatments are frequently used in many diseases, including cancers and AIDS. The main aims of these treatments are to reduce toxicity, decrease or delay drug resistance, and improve drug efficacy by inhibiting the activity of a specific target or groups of targets in a cell. The net effect of combination drug efficacy is mainly quantified and interpreted by various terminologies like synergy, additive, agonism, and antagonism based on drugs dose ratio. In single or combination drug treatment, drug action occurs on cells due to the intermolecular level interaction of drugs with protein/DNA/RNA/Enzyme. This type of inter molecular level interaction can be detected with the help of docking software. The current study aims to identify the inter-molecular level interaction of combination drug Crizotinib and Temozolomide with C-MET, C-ROS1, and ALK targets in Glioblastoma Multiforme(GBM). To identify this, we performed forward and reverse docking of drugs with these proteins, and the results were evaluated by drug properties and the complex energy. From the analysis study, we recognized that first, Crizotinib and then, after Temozolomide bounded docked complexes showed the least complex energy in all the docked complex structures, and the better complexes were identified from the result by MD simulation.

Efficacy of Naproxen Plus Gabapentin Vs Naproxen Alone in Relieving Post-Extraction Pain of Impacted Mandibular 3rd Molar

Background: Evaluate the efficacy of using combination drug treatment to relieve post extraction pain of impacted mandibular third molar by using Naproxen plus Gabapentin versus Naproxen alone. Aim: To evaluate the efficacy of using combination drug treatment to relieve post extraction pain of impacted mandibular third molar by using Naproxen plus Gabapentin versus Naproxen alone. Methods: Randomized control study, outcome was evaluated by measuring Pre – Operative and 24-Hour Post – Operative Pain status on Visual Analogue Scale and Wong Baker’s Face Pain Rating Scale. Results: Combination therapy (Naproxen and Gabapentin) was effective in significant pain reduction at 12 Hour and 24-Hour Post Extraction period. With 26 patients out 31 presented with Pain Scale of 0 on combination therapy while only 3 out of 31 for naproxen alone after 24 hours. Conclusion: Enhanced effect of combination therapy of naproxen with gabapentin in reducing post extraction pain of impacted mandibular third molar with respect to naproxen alone. Keywords: Naproxen, Gabapentin, Combination Therapy, Post Extraction Pain, Post Extraction Analgesia, Efficacy.

Oral Submucous Fibrosis: An Overview

ABSTRACT Oral submucous fibrosis (OSMF) is a chronic and potentially malignant condition of the oral cavity. It occurs predominantly in India and Southeast Asia. The pathogenesis of OSMF is not well established, but it is believed to be multifactorial. Chewing of betel quid (containing areca nut, tobacco, and slaked lime) has been recognized as one of the most important risk factors. It is characterized by a juxtaepithelial inflammatory reaction followed by fibroelastic changes in the lamina propria and associated epithelial atrophy. The disease affects most parts of the oral cavity as well as the upper third of the esophagus. The abnormal fibrosis causes blanching and stiffness of the mouth, with eventual immobility of the lips, cheeks, tongue, soft palate, and uvula. Treatment of OSMF is difficult; a combination drug treatment is administered. In patients with severe disease, physical therapy and/or surgery is added to drug therapy.
