Abstract
Introduction: It is a well-known phenomenon that nonsteroidal anti-inflammatory drugs cause gastric mucosal damage. Amlodipine is a third generation dihydropyridine-type calcium channel blocker; it can inhibit inflammatory cytokines and enhance antioxidant defenses. N-acetylcysteine can act both as a precursor of reduced glutathione and as a direct ROS scavenger. Moreover, N-acetylcysteine has been purported to have anti-inflammatory properties.
Materials and methods: 34 albino Wistar rats were used. The model of gastritis was induced by subcutaneous Indomethacin prepared in 5% sodium bicarbonate administered at a dose rate of 9 mg/kg for two days at 24h intervals. N-acetylcysteine (500 mg/kg), Amlodipine (10 mg/kg) and N-acetylcysteine (500 mg/kg) combined with Amlodipine (5 mg/kg) were administrated for seven consecutive days beginning 24 h after the first Indomethacin injection. Rats were sacrificed under ether anesthesia on the 8th day. The stomach injury was assessed by macroscopic damage and histological study.
Results and discussion: The results showed that macroscopic stomach damage scores caused by administration of Indomethacin did not significantly decrease by administration of N-acetylcysteine alone (p>0.05), but it decreased significantly by administration of Amlodipine alone or by its combination with N-acetylcysteine (p<0.05). Microscopic stomach damage scores did not significantly decrease by administration of Amlodipine or N-acetylcysteine alone (p>0.05), but they decreased significantly by administering the combination of Amlodipine with N-acetylcysteine (p<0.05). Administration of Amlodipine with N-acetylcysteine showed significant reduction in the severity of the gastric inflammation induced by Indomethacin, which was evidenced macroscopically and microscopically.
Conclusion: This study concluded that administration of Amlodipine with N-acetylcysteine produce obvious enhancement in gastritis induced by Indomethacin.

Front Pharmacol 2022; 13:902305. [PMID: 35721193 PMCID: PMC9198715 DOI: 10.3389/fphar.2022.902305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 05/17/2022] [Indexed: 11/15/2022] Open
Abstract
Amlodipine is a Ca2+ channel blocker commonly used to cardiovascular diseases such as hypertension and angina; however, its anticancer effects in lung cancer A549 cells remain unknown. In the present study, we explored the antitumor effects and molecular mechanisms underlying the action of amlodipine in non-small cell lung cancer (NSCLC) A549 cells in vitro and in vivo. We observed that amlodipine suppressed the proliferation of A549 lung cancer cells by arresting the tumor cell cycle. Mechanistically, our results revealed that amlodipine could attenuate the phosphoinositide 3 kinase (PI3K)/Akt and Raf/MEK/extracellular signal-regulated kinase (ERK) pathways through epidermal growth factor receptor (EGFR) and modulated cell cycle-related proteins such as cyclin D1, p-Rb, p27, and p21. Subsequently, amlodipine combined with gefitinib could synergistically inhibit cell proliferation by arresting the cell cycle. Moreover, amlodipine combined with gefitinib effectively attenuated the growth of A549 lung cancer xenografts when compared with monotherapy, affording an excellent therapeutic effect. Collectively, our results indicate that amlodipine alone or combined with the novel anticancer drug gefitinib might be a potential therapeutic strategy for NSCLC patients with wild-type EGFR.

Abstract
Breast cancer is the most common cancer among women and is considered a developed country disease. Moreover, is a heterogenous disease, existing different types and stages of breast cancer development, therefore, better understanding of cancer biology, helps to improve the development of therapies. The conventional treatments accessible after diagnosis, have the main goal of controlling the disease, by improving survival. In more advance stages the aim is to prolong life and symptom palliation care. Surgery, radiation therapy and chemotherapy are the main options available, which must be adapted to each person individually. However, patients are developing resistance to the conventional therapies. This resistance is due to alterations in important regulatory pathways such as PI3K/AKt/mTOR, this pathway contributes to trastuzumab resistance, a reference drug to treat breast cancer. Therefore, is proposed the repurposing of drugs, instead of developing drugs de novo, for example, to seek new medical treatments within the drugs available, to be used in breast cancer treatment. Providing safe and tolerable treatments to patients, and new insights to efficacy and efficiency of breast cancer treatments. The economic and social burden of cancer is enormous so it must be taken measures to relieve this burden and to ensure continued access to therapies to all patients. In this review we focus on how conventional therapies against breast cancer are leading to resistance, by reviewing those mechanisms and discussing the efficacy of repurposed drugs to fight breast cancer.

Abstract
Nanogels are drug delivery systems that can bypass the blood-brain barrier and deliver drugs to the desired site when administered intranasally. They have been used as a drug delivery platform for the management of brain diseases such as Alzheimer disease, migraine, schizophrenia and depression. nanogels have also been developed as vaccine carriers for the protection of bacterial infections such as influenza, meningitis, pneumonia and as veterinary vaccine carriers for the protection of animals from encephalomyelitis and mouth to foot disease. It has been developed as vaccine carriers for the prevention of lifestyle disease such as obesity. Intranasal administration of therapeutics using nanogels for the management of brain diseases revealed that the drug transportation was via the olfactory nerve pathway resulting in rapid drug delivery to the brain with excellent neuroprotective effect. The application of nanogels as vaccine carriers also induced significant responses associated with protective immunity against selected bacterial and viral infections. This review provides a detailed information on the enhanced therapeutic effects, mechanisms and biological efficacy of nanogels for intranasal administration.

Biomed Pap Med Fac Univ Palacky Olomouc Czech Repub 2018; 162:71-78. [PMID: 29765168 DOI: 10.5507/bp.2018.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Accepted: 04/16/2018] [Indexed: 12/30/2022] Open
Abstract
Patients who are unable to receive oral medication (p.o.) are a major problem in outpatient settings, especially in home health care systems. Mucosal administration of drugs offers an alternative to the oral route, especially when the parenteral mode cannot be used. There are three main pathways of mucosal administration: sublingual/buccal, intranasal and rectal. We discuss the possibility of mucosal delivery of antihypertensive drugs. Perindopril arginine and Amlodipine besylate are registered in the EU as orodispersible tablets for oromucosal delivery, however, they are not available in all countries. For this reason, we describe other drugs suitable for mucosal delivery: Captopril and Nitrendipine in the sublingual system and Metoprolol tartrate, Propranolol and Furosemide by the transrectal route. Based on the published data and common clinical practice we discuss the use of mucosal delivery systems of all these antihypertensive drugs with special attention to their pharmacokinetics. We illustrate this mini-review with a case report of the prolonged-term use of mucosal delivery of sublingual Captopril and Nitrendipine combined with rectal Metoprolol tartrate and Furosemide in a patient with severe hypertension unable to receive medication p.o. This is also a report on the first human use of Furosemide-containing suppositories as well as prolonged-term transmucosal administration of these four drugs, describing a practical approach leading to successful control of severe hypertension with four antihypertensive drugs delivered via the mucosal route. The treatment was effective and without side effects; however, the long-term safety and efficacy of such therapy must be confirmed by randomized clinical trials.
