SPRITAM- World's 1st 3-D printed tablet

                                                  SPRITAM- World's 1st 3-D printed tablet

            The U.S. Food and Drug Administration (FDA) has approved for the first time a pill or a tablet manufactured from 3-D printing technology. SPRITAM is the trademark registered tablet which is going to be marketed by 'Aprecia Pharmaceuticals Company' with active pharmaceutical ingredient being 'Levetiracetam'. Levetiracetam is an anti-convulsant drug used as an adjunctive therapy for the treatment of partial onset seizures, myoclonic seizures and primary generalized tonic-clonic seizures in adults and children with epilepsy.
            Don Wetherhold, CEO of Aprecia Pharmaceuticals, claims that by combining 3-D printing drug technology with highly prescribed epilepsy treatment, Spritam would fulfill the need for patients which struggles with their current medication experience. A porous formulation of the drug levetiracetam was developed by 3-D printing technology using its proprietary drug platform ZipDose technology that disintegrates rapidly with just a sip of water even at a high dose of 1g. Printing the powdered drug allows layers of active pharmaceutical ingredient (API) to be packed more tightly in a tablet to produce precise doses while the excess powder is blown off. 3-D printing works by creating an object layer by layer. In the case of medicines, printers are adapted to produce API rather than polymers which are more commonly used. Thus, 3-D printing of the drug offers a great potential in developing "personalized medicine" in medical institutions since the amount of drug can be varied accordingly to suit the patient's specific needs. Thus, medical practitioners would know how much amount of the drug in the pill is to be intended for a particular patient considering his/her various physico-chemical, genetic, environmental, occupational parameters.
           According to company sources, Spritam (levetiracetam) is expected to be available in the first quarter of 2016. In clinical trials, the most common adverse effects in people taking Spritam included sleepiness, weakness, dizziness, and infection. In children, tiredness, aggressive behavior, nasal congestion, decreased appetite, and irritability have also been observed.

NIPER-JEE STUDY PREPARATION TIPS

                                       NIPER-JEE PREPARATION STUDY TIPS
            National Institute of Pharmaceutical Education and Research (NIPER) is the first national level institute in pharmaceutical sciences with an objective of becoming a centre of excellence for advanced studies and research in the same field. The Government of India has declared it as an 'Institute of National Importance' and is an autonomous body set up under the Department of Pharmaceuticals, Ministry of Chemicals and Fertilizers, Government of India. It offers PG and Ph.D courses under various disciplines such as Pharmaceutical Medicinal Chemistry, Pharmaceutics, Pharmacology, Pharmaceutical Analysis, Pharmaceutical Biotechnology, Toxicology, Clinical Research, Traditional Medicines, Natural Products, Pharmacy Practice, Pharmacoinformatics and MBA (Pharmacy). PG courses include M.S (Pharm), M.Pharm courses in the above areas as well as M.Tech in Pharmaceutical Technology in fields such as Pharmaceutical Biotechnology, Process chemistry and Formulations Technology. NIPERs are located currently at 7 places in India such as
1. Chandigarh or Mohali (S.A.S Nagar)- 1st NIPER to be established in late 1990s,
2. Ahmedabad (Gujarat)
3. Hajipur (Bihar)
4. Kolkata (West Bengal)
5. Rae Bareli (Uttar Pradesh)
6. Guwahati (Assam)
7. Hyderabad (Telangana)
 For more further information you can refer www.niper.gov.in and to respective websites of these 7 NIPER schools.
             NIPER-JEE is a 200 question paper and a paper-pen exam wherein you have to darken the circles on the answer sheet or ORS (Objective Response Sheet) for the correct option/ answer with a duration of 2 hours. Like GPAT, 25% deduction in marks in case of wrong answer is also applicable in NIPER-JEE. Only GPAT/GATE qualified candidates are eligible for appearing in NIPER-JEE exam. There is no as such a well-defined syllabus for NIPER-JEE. So the questions which can be asked are slightly unpredictable. But the general trend of the examination is more or less set and with the below tips you might be able to crack NIPER-JEE with flying colors.

STUDY TIPS-
1. Take your watch along with you at the examination hall. Since you have to solve 200 questions from 2 hours, try to plan your work of solving questions. If you calculate, you have just 36 seconds to solve 1 question. So try to set smaller targets such as solving 25 questions in each 15 minutes of 2 hours. If you strictly follow it, then there is a much greater chance of solving the paper in time. At the end of 15 minutes, if you observe that you are unable to solve the target of 25 questions, leave the remaining questions and move on to next question which is a multiple of 25. Later on if you have time left with you then you can have a look on the questions which were left before. Going through all the 200 questions is very much important since you never know, easy questions may be at the back-end of the question paper like from say 170 / 180 to 200.
PERSONAL EXPERIENCE- In my NIPER-JEE 2014 question paper, questions from 180 to 200 were very easy and due to my planning I was able to have a glance of all 200 questions and was thus able to attempt 140-150 questions.

2. Make your GPAT preparation strong enough. This acts as the base for your NIPER-JEE preparation. If you are very thorough with the core pharma subjects, then your preparation for NIPER-JEE is half done. Make your basics about pharmacy knowledge very clear from subjects like Physical Pharmacy, Pharmaceutical Engineering, Pharmaceutics, Pharmacognosy, Pharmaceutical Analysis, Pharmacology etc.

3. A lot of questions are asked on subjects like Biochemistry, Microbiology, Biotechnology, Genetic Engineering, Molecular Biology. Almost 40-50 questions comes from these areas. So don't neglect these subjects although they are neglected during GPAT preparation.
If you are preparing for your ICT-BPT entrance exam too along with NIPER-JEE, then your preparation for NIPER-JEE becomes a whole lot easier because up to 60% questions in ICT-BPT entrance exam comes from those above subjects (Refer ICT-BPT entrance exam syllabus to get an idea).

4. 5-10 questions have been regularly asked on Novel Drug Delivery Systems (NDDS), name of polymers used in formulation, their basic structure etc.

5. About 8-10 questions are asked on basics of organic chemistry, name reactions and stereochemistry.

6. Approximately 5-10 questions are compulsorily asked based on
a.General Knowledge,
b. Current affairs of the country,
c. Business and Trade Acts & Rules ,
d.Patents and trade treaties like GATT, WTO etc.,
e.statistics,
f. recent US-FDA approved drugs,
g.pharma company's brand products,
h. major pharma / biopharma company take-overs in recent years,
i. Noble Prize winners (at least Indian Noble Prize winners and the year in which they were won and also the Noble Prize winners of the current years should be known.
For e.g., if you are giving NIPER-JEE 2015, then Noble Prize winners of 2015 in the sub-fields should be known.

PERSONAL EXPERIENCE- In my NIPER-JEE 2014 paper, a question was asked on the "subject" on which the Noble Prize was conferred to the winners in the field of Physiology-2014.

f. Questions like "Who is the President of BCCI?", "Foundation year of government organizations like SBI, RBI, AGMARK etc", "Venue and years of International Sports Tournaments like ICC Cricket World Cup, FIFA Football World Cup, Olympic Games etc" and other questions on general Indian politics can be asked.

7. Start reading newspapers in order to gain a significant insight on general knowledge and current affairs of the country. Try to note it down in a notebook so that you don't forget it.

8. Most questions are directly asked and are easy as compared to GPAT. But since time is a limiting factor during in NIPER-JEE, speed and accuracy is very much required to complete the paper. Second glance on the questions may not be possible. Also, since NIPER-JEE is not an online-based exam, changing of answer of the question is not possible once the option circle has been darkened. So be very sure of your answer to the question attempted.

                                               ALL THE BEST AND DO WELL !!!!

MISCELLANEOUS TOPICS TO STUDY IN GPAT...

                                        MISCELLANEOUS TOPICS TO STUDY IN GPAT...
      Hello friends, I hope you would have liked the GPAT guidance and tips series so far. But this series is coming to an end with this last post. In May, we will start a new guidance series on NIPER-JEE, ICT-BPT-CET and MAH-PH-CET on the same lines of GPAT guidance. Till then you can view other posts which we would be publishing till May and of course thereafter too.
      So lets begin with the guidance on 'miscellaneous topics'. Now one would say that lets focus on the main topics of pharmacy and omit the other allied topics since, first of all, its difficult to remember concepts of all 4 years and, secondly, time is a limiting factor during GPAT preparation.
But please please don't ever ignore these miscellaneous topics since collectively at least  on an average 5-6 questions can be asked on such allied topics like PHARMACEUTICAL MANAGEMENT, FORENSIC PHARMACY, CLINICAL PHARMACY , MICROBIOLOGY and all of which are relatively easy to attempt and are quite handy for increasing your GPAT score.

1. PHARMACEUTICAL MANAGEMENT- Focus more on the product life cycle such as growing phase, stationary phase , decline phase etc., and their significance and also on the economics part such as formula for retail pricing of drug product, various authorities like NPPA (National Pharmaceutical Pricing Authority), DPCO (Drug Price Control Order) etc.

My personal experience- In my slot, a question was asked on the product life cycle.

2. FORENSIC PHARMACY- At least 2-3 questions can be asked irrespective of slot in which you are in for GPAT exam. So be thorough with
a. Schedules (A to Z) of D&C Act-1940 and Rules 1945
b. Patents and IPR- Full topic- especially concept of process patent, product patent, India's patenting regime, trademark, copyright, patenting authority and the life of patent.
c. Other Acts like Narcotic Drugs and Psychotropic Act 1985 (NDPS), Insecticides Act 1968, Factories Act 1948, Excise Duties Act 1955, Drugs and Magic Remedies Act 1954 etc. should be mainly focused on.

My personal experience- 4-5 questions were asked from this subject in my slot. 2-3 were asked from Patents, 1 from Insecticides Act,, 1 from Excise Duties Act.

3. CLINICAL PHARMACY- From this subject, questions are more centered on clinical trials- history and the phases involved in the trials. The description, duration, significance as well as the subjects involved in each phase should be thorough.

My personal experience- 2 questions were asked -1 about the clinical trials phases and 1 was a very unique question from history of clinical trials history which I still remember-
It said that Nazis used to administer new drugs directly to Jews in their concentration camps which was an inhuman practice. So to abolish this, which conference/ convention was called for??
( I had no idea what the answer was and just left it without thinking !!!)

4. MICROBIOLOGY- Hardly any questions can be asked from core microbiology, but you should be thorough with the growth curve kinetics of micro-organism, sterilization principles, D- value, Z- value and their significance.
Questions from microbiology are more oftenly asked in NIPER-JEE and ICT-BPT-CET rather than GPAT.

RECOMMENDED BOOKS-

1. PHARMACEUTICAL MANAGEMENT-
Philip Kotler, K.L. Keller, A. Koshy, M. Jha, 'Marketing Management', 14th Edition, Pearson India Publishers, 2012.

2. FORENSIC PHARMACY-
Kuchekar, Kadtare and Itkar, 'Textbook of Forensic Pharmacy', 9th Edition, Nirali Prakashan, 2012.

3. CLINICAL PHARMACY-
A. Dr. H.P. Tipnis and Dr. A. Bajaj, 'Clinical Pharmacy', 1st Edition, Career Publications, 2003.

B. Roger Walker and Cate Whittlesea, 'Clinical Pharmacy and Therapeutics', 4th Edition, Elsevier Publishers, Churchill Livingstone Imprint, 2007.

4. MICROBIOLOGY-
M.J. Pelczar Jr., E.C.S. Chan,  N.R. Krieg, 'Microbiology', 5th Edition, McGraw Hill Education (India) Pvt. Ltd., 2001.
  You can refer 'Lachman' and 'Remington' for sterilization principles too.

         Now you would have got a certain idea about how the above miscellaneous topics are equally important. So please don't try to neglect those.
Also you would have gained at least some idea about what GPAT exam exactly is, which subjects / topics to more focus and also which books to study.
ALL THE VERY BEST FOR EXAMS !!
This was all about the GPAT guidance series. Hope you would have liked this part too. Any suggestions, questions, feedback is always welcome to our team.
Thank You

PHARMACOGNOSY- The 'NATURAL' Pharmacy

                                     PHARMACOGNOSY- The 'NATURAL' Pharmacy
            To begin with, Pharmacognosy is the most neglected and irritating subject to the most of the pharmacy students since they struggle in remembering the biological/official names of the plant/animal drugs. This is the most common reason they give to everyone when you ask about this subject.
            But let me share some interesting and true facts about this subject. Pharmacognosy is one of the most versatile subject which you will find in the B.Pharmacy syllabus. I say so because it is here your knowledge of
1. Pharmaceutical Analysis
2. Pharmaceutical Chemistry
3. Some part of Pharmaceutics and Pharmacology and
of course your pharmacognosy knowledge is tested. You can easily co-relate what you learnt in the above subjects in pharmacognosy.
Let me explain you with an example- Consider that you are trying to find a new drug that will help cure a new or an existing disease which itself has no cure to this date. Many chemists have failed in doing the same. Then the only option remains with you is to discover the drug from natural sources.
So, you will require the knowledge of 'Pharmaceutical Analysis' to detect, separate or isolate and purify the particular drug. Then you should have a sound knowledge of 'Chemistry' so as to know the structure of that particular constituent and also its Structure Activity Relationships' (SAR). Now when you know the drug constituent, the mechanism of action of that drug as well as the appropriate dosage form in which you can administer to the patient should be known which comes under 'Pharmaceutics' and 'Pharmacology'.
             This was the first true fact about pharmacognosy. The second-most important fact being that it is not always possible to synthesize a new drug in the laboratory every time. In fact, some drugs are chemically synthesized when the structure of the naturally obtained drug is known and on the basis of that structure, scientists are able to synthesize by chemical means. E.g.- Taxol- Anti-cancer drug
             The third important fact being many of the allopathic or artificially synthesized drug have many adverse reactions, side effects etc on the other hand the case with the naturally obtained drugs is not so.
              India is very much fortunate to have a rich natural diversity such that almost all kinds of plants, animals, minerals etc are found here from which medicinal substance can be derived. Ayurveda is one of the oldest medical science in the world is a gift to the world from India itself.
              Now coming towards GPAT point of view, unfortunately, pharmacognosy is one of those subject which has to be mugged and many things like botanical name, microscopy, macroscopy, uses, structure, biochemical pathways like shikimic acid pathway, alkaloid synthesis pathway has to remembered and for all these you need PRACTICE and that too lot many times so that you perfectly remember at the day of exam.
TIPS- 1.  In MICROSCOPY and MACROSCOPY studies try to focus more on those natural drugs which have unique features- For e.g.- Casperian stripes in case of Lobelia, acetic acid smell in case of karaya gum- why? etc
2. Be very much thorough with bio-genetic/ biosynthetic pathways, botanical names, structures.
3. Try to remember SPECIAL AND UNIQUE THINGS like the cultivation and collection of drugs like opium (the various traditional instruments used), tolu balsam, peru balsam etc, life cycle of ergot fungus, colchicum etc.

RECOMMENDED BOOKS FOR PHARMACOGNOSY-

1. Biren Shah, A.K. Seth, "Textbook of Pharmacognosy and Phytochemistry", 2nd Edition, Elsevier Publishers (India) Pvt Ltd., , 2013.

2. W.C. Evans, "Trease and Evans Pharmacognosy", 16th Edition, Saunders Publishers, 2009.

NOTE- I have not mentioned chapter-wise books to refer for pharmacognosy because these two books are the 'BEST' for almost all the topics mentioned in the GPAT syllabus and I would say if you perfect these two books then there is no need to worry for pharmacognosy not only in GPAT but also in NIPER-JEE and other competitive exams.

This was all about 'PHARMACOGNOSY' part.. In the next part we would cover all miscellaneous topics included in GPAT syllabus like Forensic Pharmacy, Management, Microbiology (Although, microbiology is included in miscellaneous and not much important from GPAT point of view, its IMPORTANT for NIPER-JEE preparation.)
       Hope you would have liked this part, too.. Any kind of feedback and suggestions are welcome by our team !!!

PHARMACOLOGY- The Only Connecting Link Between Pharmacists and Doctors...

            PHARMACOLOGY- The Only Connecting Link Between Pharmacists and Doctors...
       The pharmacology section in the GPAT syllabus deals with the 'Anatomy, Physiology and Pathophysiology' (APP) part which most of us have studied in the first two years of Bachelor's course in Pharmacy and of course the pharmacology part which we studied in the last two years of our B. Pharmacy.
        Many students will try to focus only on the pharmacology part and will try to neglect the APP part as the common sense itself says that pharmacology is much more important than learning APP part. But please don't nurture this misconception as it will prove costly during GPAT exam. It is very much important to focus on both the parts equally since you don't know which questions may appear in your GPAT paper slot.
(My personal experience- In my paper, almost 4-5 questions were asked from APP and just 2-3 questions from pharmacology.)
        In APP part it is very much important to focus on pathophysiology of disease/disorders and general anatomy part (especially of bones, joints, spinal cord, heart, brain etc- try to focus more on important organs of our body).
In pathophysiology of disease you should be clear about the mechanism of cause of disease/disorders, life cycle (if any) of parasite e.g. malaria, causative microbe and the affected organ.
        In pharmacology part ,try to focus more on the mechanism of action of drug in treating a particular disease/disorder, pharmacological actions of drug, major side-effects or adverse drug reactions reported, contraindications of drug in certain circumstances or in the presence of certain drug or an already-present disease in the patient.
Side-effects, adverse drug reactions and contraindications of major drugs should be thorough enough since the are one of the favorite questions asked in GPAT. (E.g. Steven-Johnson syndrome is a side effect of antibiotics and sulfa drugs OR "X" class of drugs should not be administered during the therapy of "Y" class of drugs etc.)
TIP- It is better to start (and of course) complete the study preparation for 'PHARMACEUTICAL MEDICINAL CHEMISTRY' and 'PHARMACOLOGY' simultaneously at one go since they are pretty much inter-related. You learn the chemistry, structure activity relationship in pharmaceutical medicinal chemistry while you continue learning the pharmacological aspects of the drug like mechanism of action, side-effects etc in pharmacology. The book "Foye's Pinciples of Medicinal Chemistry"- 7th Edition has included a lot of pharmacology part too. But still for some part you need to refer the pharmacology books also.

AN ANTIBIOTIC AFTER 25 LONG YEARS- A COMEBACK FINALLY !!!

                    AN ANTIBIOTIC AFTER 25 LONG YEARS- A COMEBACK FINALLY !!!
        January 2015 gave rise to a new antibiotic discovered after a long wait of 25 years (the last antibiotic was discovered in 1987). This discovery can be considered as a 'NEW YEAR GIFT TO MANKIND' because the uniqueness of antibiotic 'TEIXOBACTIN' lies in the fact that it is active against Gram positive bacteria which has acquired resistance over other antibiotics.
        There was a fear in the minds of people that antibiotic will no longer be beneficial in coming years due to the spread of resistance over antibiotics in the recent years e.g. Multi-Drug resistant- Tuberculosis (MDR-TB). Thus the discovery comes as a ray of hope in treating resistant bacterial as well as other microbial species.
         Teixobactin was isolated from the previously uncultured soil bacteria by iChip (isolation chip) technology. It is a cell wall biosynthesis inhibitor by binding to the lipid precursors (especially lipid II) of peptidoglycan. The blocking of lipid precursors results in the inhibition of peptidoglycan which in turn results in the cell lysis of the concerned bacteria.
         Teixobactin is effective in vitro against most of the Gram positive bacterial species like Mycobacterium tuberculosis, Staphylococcus aureus, Bacillus anthrasis, Clostridium difficile, enterococci and in in vivo it is effective against methicillin-resistant Staphylococcus aureus (MRSA) and Streptococcus pneumoniae. The in vivo activity was, however, tested on mice and still clinical trials are yet to be carried on human beings.
TEIXOBACTIN IS NOT PROVED TO BE EFFECTIVE AGAINST GRAM- NEGATIVE BACTERIA.
         One of the co-discover has stated that Teixobactin will hit the market only in next 5-6 years. However, pharmaceutical companies are reluctant to invest in the manufacture, development and marketing of new antibiotics due to the fear that due to use prolonged use, it may acquire resistance.
Teixobactin is discovered in Northeastern University,Boston with Prof. Kim Lewis being the lead research scientist.
          Since, micro-organisms are getting stronger and stronger by the day due to the resistance, we need to strictly follow the proper instructions by our family doctor, pharmacist or any healthcare expert regarding the proper course and administration of antibiotics. 
Self-medication should be avoided, the whole course of antibiotic should be completed even we feel better by the 2nd of 3rd day of medication regime (considering it as a 5-day regime). If any past "antibiotic-resistant" experience has occurred then that should be reported to the doctor beforehand.
        Lets hope for a better future with more effective antibiotics being discovered in the coming future to save the mankind from dare consequences of antibiotic-resistance of microbes..!!!

PHARMACEUTICAL ANALYSIS- Safe-guarding the pharmaceuticals !!!!

                 PHARMACEUTICAL ANALYSIS- Safe-guarding the pharmaceuticals !!!!
        True to its name , "Pharmaceutical Analysis" is the subject which deals with maintaining the identity and purity (quality) of the drug. It describes various techniques which are literally involved for detecting any impurity in pharmaceuticals / active pharmaceutical ingredients (APIs) and quantification of the API content or impurity content in the concerned product. Thus, it safeguards the pharmaceuticals from any toxic impurity or residual solvents which might be present that can harm the product, in turn harming the consumer (patient). Patient safety comes first in healthcare industry.
Also let me clear myself about the term "impurity". Impurity not necessarily means it is always harmful to the product or patients, but it is just 'undesirable' in our concerned product.
        From GPAT point of view, this subject is very , very important. You should be crystal clear about the basics of chemistry as well as physics (which we learnt in our junior college- 11th and 12th standard) to move forward in learning this subject because almost over 2/3 rd part of this subject deals with principles, equipment's, working of the same and applications which requires lot of physics.
        You should be mainly clear about the principles involved and specific instruments (e.g. source, detectors etc.) used in each analytical technique. Also in case of IR (Infrared Spectroscopy), NMR (Nuclear magnetic Spectroscopy) you need to remember the absorbance value and chemical shift value of each functional groups (most favourite questions in GPAT). In MS (Mass Spectrometry), you should be clear about the fragmentation patterns and the characteristic m/z value of certain functional groups like alcohols, carboxylic acids, ketones etc.
In case of titrations like non-aqueous, complexometric, redox etc the indicators used, nature of analytes suitable for them should be remembered.
In case of chromatographic techniques like HPLC (High Pressure Liquid Chromatography), GC (Gas Chromatography), TLC (Thin Layer Chromatography) etc., stationary and mobile phases used as well as the modifications and advancements in the original techniques to suit the needs of certain nature of analytes should be known to you.

PHARMACEUTICAL MEDICINAL CHEMISTRY- Dealing with the structure- Part- II

         PHARMACEUTICAL MEDICINAL CHEMISTRY- Dealing with the structure- Part- II
      In the previous post we covered some basic funda's regarding chemistry. Now with the basics done its time to move ahead and master the subject of interest- "Pharmaceutical Medicinal Chemistry". This subject basically will deal with the SAR- Structure Activity Relationship, MOA- Mechanism of Action and chemical synthesis of pharmaceutical agents or simply 'drugs'.
      In SAR, we should try to focus on the functional groups in a particular moiety which are responsible for the action of the drug/ binding with the receptors. It can also include the 'prodrug' approach as well. E.g. Which functional group is susceptible for the making prodrug.
      In MOA, it is sometimes essential to know the sequence of reactions which actually take place with the drug (especially prodrug) in the body on administration. MOA is more of concern in 'pharmacology' which we would cover in the upcoming posts. Rather, I would personally suggest to study pharmacology and medicinal chemistry at the same time. It will serve 2 purposes-
1. Time-saving activity.
2. After knowing structure, SAR and chemical synthesis of particular class of drugs in chemistry (for e.g. anti-viral agents), you can look its MOA, ADR (Adverse Drug Reactions), S/E (Side-effects) and other aspects in pharmacology. Thus, you will immediately link the chemistry and pharmacological actions of the drug instantly and trust me, it really helps a lot.. Its like hitting 2 bird with a single stone !!
       In this post we will also try to cover 'Biochemistry'. Most of the questions regarding with biochemistry is more centered around the biochemical pathways. Glycolysis, TCA cycle are favourite ones. Questions may or may not be asked on enzyme kinetics, enzyme immobilization, nucleic acids- DNA, RNA etc.,  genetic mutations etc. These topics are more of a concern in NIPER-JEE preparation. We would also cover guidance and tips about NIPER-JEE too once GPAT series ends.
