Physical Properties of Pre-formulation.pptx
Preformulation studies provide a path for formulation development and drug product development in respect of drug form, adjuvants, composition, physical structure, and chemistry of drug molecules, facilitating pharmacokinetic and biopharmaceutical properties evaluation, adjustments, and their implementation.
Preformulation studies focus on the concepts of physicochemical properties which are vital for any new drug molecule and/or proteins/peptides. These properties not only affect their therapeutic efficacy but also the development process of their specific dosage form.
Preformulation Studies
The chapter deals with the preformulation studies that have to be considered while designing a dosage form and developing a formulation that is suitable for a patient. Here, physical and chemical properties of a drug substance are studied along with biopharmaceutical classification of drugs. Also a detailed study on the application of preformulation studies in different dosage forms are also studied.
Opthalmics Preparation and its Evaluation parameters
Contented and Precise, opthalmic preparation , preparation and evaluation of opthalmics
LIQUID ORALS INDUSTRIAL PHARMACY
Liquid oral topic in Industrial Pharmacy contains many topics like solution, elixirs, syrups, emulsion, and suspension. This topic includes general introduction, types, formulation, components, uses, and Quality control tests. These are also beneficial in other subjects like Pharmaceutics.
Pellets
A comprehensive interpretation of pellets based on their definitions, advantages, disadvantages, mechanism of pellet formation and growth, pelletization techniques, formulation requirements, and the equipment system for manufacture of pellets.

Pelletization
pellets can be defined as multi particulate system or multiunit system
They are spherical particulates manufactured by agglomeration of the powder granules containing drug substance and excipients.
Pellets can be prepared by a special technique called Pelletization.
This technique is referred to an agglomeration process that convert fine powder or granules of bulk drug or excipient in to small , free flowing , spherical or semi spherical pellets .
Multi particular drug delivery system especially suitable for achieving controlled delay released oral formulation with low risk of dose dumping, flexibility of blending to attain different release patterns as well as reproducible and short gastric residence time.
Multi particulate drug delivery system are mainly oral dosage form consisting of a multiplicity of small discrete units each exhibiting some desire characteristics.

capsule manufacturing defects.pptx
These defects can cause serious injury and harm. When this occurs, you should speak with our product liability attorneys in Denver. You may have a viable claim to file a product liability lawsuit against the negligent manufacturer.Capsules are solid dosage forms in which the drug substance is enclosed within either a hard or soft soluble shell. Generally the shells are formed from gelatin. The capsule may be regarded as “container” drug delivery system, which provides a tasteless/odorless dosage form without the need of a secondary coating step, as may be required for tablets.Capsules are one of the essential components of the pharmaceutical sector. They are mainly used to hold dry powder or little pellets of medication and are made using specific machinery and techniques. The capsule's production method entails pharmaceutically active ingredients, additives, and a cover. Every pharmaceutical business understands capsule manufacturing takes time, and the reason is the critical measures.

i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Objectives of Preformulation
- 1. OBJECTIVES OF PREFORMULATION By: KASHVI DESAI KRUPA BAROT
- 2. • Preformulation is the stage of development during which the physicochemical properties of the drug substance are characterized and established. • Objective of preformulation • study is to develop the elegant, stable, effective and safe dosage form by establishing kinetic rate profile, compatibility with the other ingredients and establish Physico-chemical parameter of new drug substances. • Physicochemical properties of drug: The ability of a chemical compound to elicit a pharmacological/ therapeutic effect is related to the influence of various physical and chemical (physicochemical) properties of the chemical substance on the bio molecule that it interacts with.
