Abstract It is a well-known fact that tablets are the most ordinary medicines in daily practice, which along with capsules represents about 70% of pharmaceutical preparations. While it is tempting to assume that all drug products are financial blockbusters, approximately 70% never generate sufficient sales to recoup their development costs. 3J0���'�7��3n�`\g|���\W�6�!n.�8� ?��cB�Ě����֚ޟG�;5o��Ӭ����=� 4705/12/2015 NGSMIPS 48. xref %�쏢 liquid. %PDF-1.4 %���� Preformulation is the branch of Pharmaceutical science that utilizes biopharmaceutical principles in the determination of physicochemical properties of the drug substance. liquid. ;�(�ܡ���'�c��'/�HȺ��6)��x�OНퟠ4D{q8͖V�t��1������.���y�d�7�t �81N :�q͵��(By�ޑ:�6Z���b��� o�c��7X� �ڕ��B��9!X���5������G��i�sӳ��Oߍ�9ݮjS��]��U-.g��|s������Wu��u� H�tUiPSY~��},y����ȦQ��c3��+ݨ�F��I���d�( ;��E�(��-��qii��elt�t����җ��g�?�jz�[�Թu��|�nj�0�-�l��d��s@t��u�">B�κ���+c����C��K�/���C�P.�ي���S���ebO���ʴ���Q�I���}6E�"��w&t�������(K�%��� YbR�Bn/v[%�Mtg�b��%��¼0l� v �&0��}�cuV���nf�9`���Ta���cUF:������aƘ)v�w��o��>6 0000001063 00000 n �#ʕ���!��oY�rQ���֣ؒ* ���� �77��4g^��*�ȔGG�'�������k�K�#+�O�b�S����m҆w�4�4hWƩ��c�s.���G��MI�$��O�>X%ם����=�sM�� �T�M+�۟�ͭ��k86�ٕ��:�`l��/p�4=�;�0�$R �P�D=$�R����p���~�� 2'+U�p����j����Y\�����괦��,�͎ Graduated cylinder was employed for density measurements and the volume taken was the value obtained after 2500 strokes using a settling apparatus.

PREFORMULATION For the achieving goals of drug and dosage forms, pre-formulation testing is a first step in the development of dosage forms before the formulation. Paracetamol, lactose, date palm mucilage and corn starch were blended to form a damp coherent mass which was screened through a sieve No 10 and dried at 60˚C for one hour. Prior to the development of any dosage form new drug, it is essential that certain fundamental physical & chemical properties of drug powder are determined. Formulation development studies achieve those optimal conditions through either the use of additives or the manner in which the drug is processed. master of pharmacy in pharmaceutics.
