Anti-obesity drugs, a scientific breakthrough?

Anti-obesity drugsWith the prevailing lifestyle trends and work culture, most people are prone to being overweight or obese. The demographic of people diagnosed with obesity is constantly weighing down the healthy population. This area has thus provides extensive research opportunities to the pharmaceuticals and healthcare fields. The raised concern can also be attributed to the fact that obesity doesn’t continue as a sole health problem. It progresses to lead to varied chronic ailments thus reducing the life expectancy of a person.

Obesity has been identified to have genetic pre-disposition factors along with being caused by excessive food intake and lack of regular physical activity. But can any of these be resolved with medication?

Drug discovery and development

Developing a drug for obesity is difficult because mechanisms that regulate energy-balance in the body are in constant interaction with a number of physiological systems. The current understanding of human physiology suggests that the number of mechanisms for energy homeostasis and appetite regulation makes it difficult to engineer drugs for obesity. While targeting neurotransmission (for hunger and satiety) seems like the best alternative, it has a wide range of side effects.

Body-weight is also affected by psychological and social factors. So, it is a common belief that pharmacotherapy cannot solve the problem of obesity. Moreover, since weight gain results from lifestyle alterations, most people feel that behavioral changes alone can help weight management. But one needs to be informed that anti-obesity drugs exist and can help a person lose up to 5-15% of his body weight. This, however, lasts only till the treatment goes on. The maintenance of the weight loss differs in different subsets of individuals.

Is the shrink brought about without the suppression of diet?

The expansion of the Anti-Obesity Drugs Market stems from the FDA’s approval of five different kinds of drugs for weight management, each of which has a different mechanism of action.

  1. Phentermine/Topiramate ER

Phentermine works on the nervous system to suppress appetite. It is also known to increase metabolism.  The exact mode of action of the secondary compound, Topiramate, has not been elucidated. The two components are packed in a gelatin capsule, the former designed for immediate release and the latter in beads for extended release. The combination was shown to work with good efficiency in clinical trials.

  1. Orlistat

Orlistat falls in the lipase-inhibitor category of drugs. It works to prevent the absorption of fats by the intestines. The drug has to be supplemented with an everyday exercise routine for an efficient weight loss.

  1. Lorcaserin

Serotonin is a chemical substance in the body that signals satiety. Lorcaserin targets serotonin receptors in the hypothalamus region of the brain to inhibit appetite. Since it interferes with neurotransmission, its intake should be with great care.

  1. Naltrexone SR/Bupropion SR

This combination of drugs works on the hypothalamic melanocortin system and the mesolimbic reward system to reduce appetite. Although developed to help overcoming alcohol and opioid dependence, it is now also associated with weight reduction.

  1. Liraglutide 3.0 mg

Liraglutide can be used as an adjunct to a low-calorie diet for weight management. It delays gastric emptying and decreases hepatic glucose production to bring about a loss in weight.

The market size of these drugs:

Although there has been considerable research, the commercialization of the products has been less. Even the aforementioned drugs come with packaged warnings of a number of serious side effects. This indicates that no ideal anti-obesity drug has been established. The ideal one should cause minimal side-effects and the sustenance of weight loss should be prolonged. To attain a control over body-weight through drugs to the same extent as a surgery has not been possible so far. Global market research reports thus suggest many opportunities for entry into the field.

There must be a detailed behavioral analysis at various stages of drug development. This will help monitor the working of the drug at the molecular level. Only a recognized pattern of the physiological responses can aid the development of an ideal anti-obesity drug.

China: Planning to be the second largest pharmaceutical market

pharmaceutical-marketThe healthcare market of China has been rising at an exponential rate and is very soon poised to overtake Japan as the world’s second largest pharmaceutical market, after the U.S. The overall value of the Chinese pharmaceutical market is estimated to grow up to $ 315 million by 2020, a profuse 650% growth from $ 48 billion in 2013.

Predictions of Chinese Healthcare Market:

As the demand for healthcare rises, the government authorities are determined to shift focus from being merely an export-based financial system, to one that sells to the Chinese patrons. Various elements contribute towards this proposed growth, one such key factor is the growth of the new middle class. These groups of consumers can meet the expense of these western drugs, particularly the ones that are used to treat conditions such as respiratory illness and depression, which is formerly, would have gone typically untreated or undiagnosed.

This growth is estimated, despite of recent parade of probes in the medicine prices and fraudulent sales practices of major companies including Merck, Glaxo, Smith Kline, Abbot Laboratories  and Baxter International in China. According to a market research, even with this backdrop of prices issues and bribery, the Chinese pharmaceutical market is on the rim of substantial development.

Under the new projected healthcare program, China is offering enlarged insurance coverage to millions of new patients. Till 2020 overall expenditure on China’s healthcare market is predicted to rise to $1 trillion from $357 billion in 2011, beside a proposed investment of $160 billion in healthcare research and development.  Analysts expect that Chinese market is maturing; it means a regulated market, albeit a growing one.

MIT Chemists Introduce Effective Molecular Treatment for Deadly Cancers


Every year, the world records 12 million cases of diagnosed cancer, and some its types can be treated with available treatments. But, there are some forms, which do not respond to present approaches. This is where drug delivery systems for cancer faces short-comes. Innovative and novel methods to treatments are being explored. These are based on micro-particle, which carry anti-cancer agents.

Such particles are injected in the affected person’s bloodstream, and directed to tumor through magnetic field of targeted drug reach. Professor Paula T. Hammond, the head of MIT’s Department of Chemical Engineering, opened up about the remedy in a conference. The team she leads us engineering a nano-particle that is one-hundredth measure of a human hair, and may be able to treat serious cancers that do not respond well to drugs.

However, the costs to trial of novel remedies today may seem a lot, In future it will yield good results. As per market research reports, clinical trials for global advanced drug delivery industry will stand at $227.3 billion by the year 2020. Here is how the super-powerful molecular treatment devised will fight deadly cancers.

New Molecular Treatment for Cancer

MIT chemists wish to create a cancer-restraining agent that will be introduced in patient’s bloodsteam, which goes to penetrate tumor tissues. The nano-particle will be small enough so as to get into the cancer cell. The nano-particle core is a tiny capsule which consists of chemotherapy drug. Thus poison will end life of tumor cells, and around the core, the experts will wrap thin nanometers of siRNA (small interfering RNA), a gene blocker.

The same is a strong negatively charged element that is covered by a protective later of polymer (positively charged). The oppositely charged molecules will stick together due to charge attraction that will give a protective later to prevent the siRNA deterioration in blood. The siRNA is a collection of molecules, which is utilized to stop a specific gene in a cell. The scientists are keen about the enormous clinical potention of such gene blockers for drug delivery and diagnostics.

A body has cells, which in bloodstream can attack anything that is foreign. The team and Hammond are devising a technique for deploying nano-particle without causing any problem to the patient. The way out was adding another negatively charged cover about the nano-particle that services the purpose of creating clod of water molecules for nano-particles for cloaking effect. It will also consist of molecules to bind at tumor cell. When in the cancer cell, it is easy to deploy the nano-particle.

Killing the Dangerous Tumor

When siRNA is employed, cancer cell is defenseless. A chemotherapy drug exudes from capsule to destroy tumor cells efficiently. On using sufficient measure of gene blockers, it is possible to answer many different types of mutations that will clear out other tumors without leaving remnants. The MIT researchers say that nano-particles were tested on animals with triple-negative breast cancer, and the therapy did reduce size of tumors, and some of the cancer cells were eliminated.

Hammond thinks her approach may be personalized. There are more treatments being tested and developed. According to the healthcare market research reports, the UT Southwestern Medical Center experts revealed findings of Stereotactic Body Radiation Therapy, which proved to be more effective than other traditional treatment, with cure rate of 98.6 percent.

As for siRNA therapy, it is backed by evidence that cardiovascular drug delivery is most innovative means in therapeutics underlying RNA interference. Rest is supposed to be seen how the treatment progressed. More clinical trials will be needed, until the drug delivery can be made available to health authority and organizations to give it a clean chit, and then present it to the market.
