Difficulties mastered are opportunities won.

“The number of novel compounds going into the market is decreasing as well as trends changing from highly soluble to less soluble drugs”. This was the opening statement made by Dr. David Harris, a fellow at Merck as well as a formulation scientist with over 20 years experience in the development of new chemical entities.

These trends he said have led to the need for a highly collaborative process in Oral development programs which in turn has created a laundry of opportunities for young graduating scientists within industry. Opportunities in areas such as per formulation analysis, pre clinical compound assessments, discovery, API development  just to mention but a few are available to young scientists.

Dr. Harris  followed these statements with a presentation on oral development Programs and what they entail.
He talked about key elements of these programs which are classified around the physical and chemical properties of the oral compound to be developed.
Amongst such properties, he mentioned the importance of stability testing, degradation mechanism studies, accelerated stability studies as well as extreme conditions stability testing which is important for drugs that will go through shipping excursions. Dissolution tests more so, bio relevant dissolution studies and clinical bio comparison are all studies that need to be undertaken in developing oral formulations.
From the above Dr. Harris clearly showed that a priori of prediction of bio performance of a drug is needed before the product is marketed. He however made it clear that most products do not make it to market as success in these studies has presented a challenge to many pharmaceutical companies thus only a few drugs actually manage to hit the market and stay in market.

Dr. Harris further went onto talking about various solid dispersion formulations and hot melt extruded solid dispersion’s giving some knowledge on why such formulations are preferred for development.
He also talked about the optimization of blend flow with respect to composition and processing of the formulation (the API and its attributes). From this he gave a comparison of spray dried and hot melt extrusion preparations in relation to their compression properties and costs of production.  He stressed the importance of establishing robustness to variations of API and excipient attributes. Optimization, he added is a very important exercise to undertake in this respect.
Dr. Harris concluded his discussion by presenting a number of case studies undertaken in the oral development program.
We thank this brilliant scientist for making time to come and speak with us.

Guest lecture to Kick off 2014 academic year!

Our first guest lecture for the spring 2014 semester was given by Jian- Xin Li, Ph.D. and technical manager at DFE Pharma North America. DFE Pharma is a company that deals with the development, production and marketing of pharmaceutical excipients for oral solid dosage and dry powder inhalation.
Dr. Jian-Xin  termed it an honor to be giving a presentation at the school in front of his hero Dr. Serajuddin. He spoke in depth about the manufacturing of bi layer tablets. The guest speaker was enthused by the positive interactions and contributions he received from the students during the lecture. The session was interactive and informative been a follow up from a previous presentation we students had during journal club. The lecture served to reinforce our knowledge on bi layer tablets.

Mr. Yin coupled his knowledge from years of surface chemistry and powder characterisation with an instrument demonstration during the workshop. He demonstrated the use of the FT4 Universal Powder Rheometer in powder processing, the applications of which include measurement of hopper flow, mixing & blending, filling and compression. With the demonstration in process, Mr. Yin explained why we need to measure powder characteristics and flow properties in particular.

During his presentation, he gave an overview of some powder processing challenges in pharmaceutical industries. Mr. Yin also touched on the fundamentals of particle interaction and the need to identify Critical Quality attributes in relation to formulation and process optimization. From the knowledge shared, we learnt that a formulator can measure, predict and eliminate common tablet processing issues such as rat-holing, bridging, sticking, segregation, lamination & capping and attrition.

We hope to have Mr. Yin back for another guest lecture.

The SJUAAPS would like to thank the students for their active participation in all the activities that the chapter organised this semester. We hope to have much more lined up for you come Spring 2014! Success as you prepare for your finals and Happy Holidays from the SJUAAPS committee.

More than just Coffee.

Conversation, coffee and treats were some of the pleasantries shared at the first coffee hour by the SJU AAPS Student Chapter. The interpersonal session was created by the committee to give students a chance to address issues they face that may not be addressed during lecture hours, lab hours or meeting with their mentors.  It was an honor to have one of our own faculty, Dr Emilio Squillante as our guest.

The charismatic doctor was presented with a laundry of questions from the student body which he addressed with wit. He made the session an open and interactive one with students chipping in on issues from academic life to career goals as well as student/faculty relationships and rapport.  The professor of Pharmaceutics emphasised the importance of being goal driven. This he said will give a student the drive necessary to see the successful completion of his/her thesis despite the hurdles research may often present.

An enthusiastic conversation it was.

When it came to career and marketability, Dr. Squillante  simply said that we should ‘fish where people aren’t fishing’. He added that a good start for entrepreneurial opportunities in Pharma is to work with the FDA. Excipient suppliers and companies dealing with technical pharma support he added were some of the best networks and contacts for one to have under their belt once out of school. He urged the students to actively participate in workshops, seminars, NJPhAST meetings, industrial tours, internships and pharmaceutical networking events to be able to get their feet into the market.

We appreciate the time Dr. Squillante took out of his schedule to share his wisdom and acumen on pharmaceutical academia and industry with us. We hope to have him back for another coffee hour.

Drug Excipient Interactions are a mainstay in drug formulation development

Last Wednesday, our graduate students were inspired by our recent guest speaker Dr. Manpreet Kaur, who spoke about fundamentals in new drug development and drug delivery research. Dr. Kaur contributed to an outstanding four NDA (New Drug Applications) in her 8 years of experience as a formulator, out of which two new drugs already made it through intense scrutiny by US-FDA into US pharmaceutical market. The topic for the presentation was focused on drug-excipient interactions that are commonly seen in drug formulation development. Dr. Kaur’s presentation was comprehensible and well explained.

Her presentation focused on the importance of paying attention to the API and excipients used in drug products through chemistry, manufacturing and control. She gave students an outline of the journey that a drug goes through from pre-clinical feasibility tests, that are mainly carried out by academia right through to the FDA filling and approval of the drug.  Dr. Kaur said that the API and excipients may change their form through any of the processes and that it is paramount that the formulator makes sure that this does not happen.

In the discussion Dr. Kaur mentioned that as a student she was given a question at her thesis defense that she has never forgotten and which she talked about. The question was to differentiate between bound and unbound water. From this she highlighted the role of water in affecting product stability. She mentioned some stabilizing methods that formulators are using to decrease unfavorable incompatibilities. Some mitigation strategies she added may be used to decrease drug excipient interactions such as  prior investigation of possible API changes, API/Excipient ratios as well as packaging considerations.

The St. John’s AAPS Students chapter had as much to showcase our wide array of activities of guest speaker scientists, equipment workshops, coffee hours, NJPhAST networking and nonetheless public spirited events.  “We aim to encourage as many pharmacists to get involved in our group. Today our chapter attracted over a 100 new members. We are truly thankful to Jackie (Jaclyn Vialet), Director of HERC, who has supported us immensely to make such a success possible for our chapter” quoted our committee chair Pulkit Khatri. The students in the fair seemed very impressed with our professional platform and we topped it up with some exciting give-aways.

All in all, it was very satisfying to see the growth of the chapter and that we are making a difference in the professional lives of our members!

AAPS student chapter stands tall on humanitarian forefront.

October 19, 2013 witnessed a remarkable event for AAPS Student Chapter as we participated in New York Cares Day. Our figureheads at College of Pharmacy, Associate Dean Sawanee and Associate Professor Dr. Jun Shao took an initiative to organize a group of about 40 enthusiastic volunteers to work at a public school 282 Q in Far Rockaway, New York. A day’s work was shown by visible improvements at the school and happy volunteers. The student volunteers started the day nice and early at 8 am from St. John’s University and proceeded forward to support the cause. Dean Sawanee, did not just initiate this cause but also took great care of our student volunteers on their mission. cca4c8677faa43bebed2370eaec2b366On reaching at 282 Q, the school authorities and New York Cares Day volunteers gave our team a warm welcome and some exciting give-away gifts as a token of appreciation. Our supervisor Dr. Shao split us into 3 groups, each assigned a different activity. The teams did a wonderful job of painting canvas murals of school logo, motto and other inspirational quotes. Hallways and staircases touch ups gave a new shine to the school.

Screen Shot 2013-10-23 at 8.43.55 PMRe-organizing the many closets and the stationary supplies was personally seen by Dr. Shao who is not only a great scientist but also inspired us with his great sense of compassion. The day ended with a satisfaction filled in hearts of student volunteers for having re-lived human values of selflessness.

Truly, an exciting job and a noble cause! We wish for more of these to enrich the lives of our young scientists.

Focus on Quality by Design and save a dollar

“If you paid more attention to the excipients you used, you would spend less money on  processing a batch of tablets,” Mr. Ken Seufert, Managing Director, North America for MEGGLE USA Inc. said. Meggle is a leading manufacturer of a wide range of lactose grades for solid dosage forms and unique co-processed excipients for direct compression as well as speciality products for dry powder inhalers.
