The transition from batch to continuous manufacturing for tablet manufacturing performance comparison and control system review
Authors: Gao Ruiyan
Published: November 2023

The pharmaceutical industry is motivated to improve tablet productivity in order to adapt to the expanding drug market. One innovative way is the transition of the traditional batch tablet manufacturing process to a continuous process. This paper aims to review the performance of continuous tablet manufacturing processes. From the comparison of continuous to traditional batch processes, the continuous tablet manufacturing process demonstrates improvements in production flexibility, robustness, and ultimately process profitability. The continuous process is proven to mix drug particles with more evenly distributed size and less segregation resulting in tablets with better quality compared to the traditional batch process. The improvement on the continuous tablet manufacturing process requires robust control system for process automation to counteract process noise and disturbances in process feed. A well-tuned Proportional Integral Derivative (PID) control is sufficient for the process to produce a desirable product. Developing a new algorithm for model predictive control (MPC) and enhancing the control system with MPC-PID control can further improve the system performance. Overall, the transition from batch to continuous tablet manufacturing is supported by pharmaceutical companies as well as organizations like Food and Drug Administration (FDA).

This study was conducted to determine the clinical profile, laboratory parameters, transfusion requirements, and transfusion-related infectious complications of adult patients with CHA. A total of 84 patients of CHA aged more than 12 years were enrolled and studied over 18 months period. 63% patients were males with mean age of 19.98±4.99 SD years and maximum (57%) in the age group of 13-20 years. Family history of CHA was present in 19 (22.61%) patients and consanguinity in 16 (19.04%) cases which were statistically significant (P<0.05). Easy fatigability (76.19%) was the most common symptom followed by dyspnea on exertion (36.19%), whereas pallor (98.80%) was the commonest finding on examination followed by spleenomegaly (40.47%). The mean average (mean±SD) values for hemoglobin was 7.37±1.23gm/dl, Red blood cell count was 4.71±0.44 million/μL, Mean Corpuscular Volume was 77±5.05 fL, Mean Corpuscular Hemoglobin concentration was 33±1.38 g/dl, Mean Corpuscular Hemoglobin was 23±1.22 pg and mean Mentzer’s index was 16.59±2.24. The most common type of CHA in our study was β thalassemia major (58%), followed by β thalassemia intermedia (17%) and Sickle cell homozygous (13%). 45% of CHA patients required monthly transfusion (p <0.05) especially sickle cell homozygous (90%) and thalassemia major (65%) patients. 24 (28.57%) patients were Hepatitis C virus-positive and 1 was HIV virus-positive. Among adult patients with CHA, β thalassemia major, intermedia and sickle cell anemia were predominant diagnoses. Consanguinity played a role in one-fifth of patients. A majority of the patients had monthly blood transfusion requirements. The high prevalence of hepatitis C virus infection is a major concern.

Background: Perimenopause is a crucial point in the life of a woman when she faces a lot of changes in her body and menstrual pattern. Abnormal bleeding patterns which can be heavy and erratic are experienced by a significant number of women in the perimenopausal transition abnormal uterine bleeding (AUB) is one of the most common gynecological problems and it affects her quality of life of a woman as well. For managing this problem, it is important to understand the clinical picture of AUB aided with imaging by ultrasound and histopathology.

Aims and Objectives: The aim of this study was to study the clinical features and the ultrasonography of the uterus and histopathology of endometrium in patients with perimenopausal bleeding and to correlate with histopathology.

Materials and Methods: A descriptive study was conducted over a duration of 12 months. All perimenopausal women who attended the outpatient department with complaints of AUB who fit the inclusion criteria were recruited in the study. Based on the clinical features, sonological profile, and histopathology report, data was analyzed to meet the aims and objectives of the study.

Results: In the study population of 105 patients, 72 patients had normal endometrium (68.5%) which was constituted by proliferative and secretory endometrium while 31.5% had abnormal endometrium constituted by disordered proliferative endometrium. For the 105 patients in the study, proliferative endometrium was seen in 41 patients and the thickness ranged between 8 mm and 10 mm. Secretory endometrium was seen in 31 patients and the thickness is ranged between 10 mm and 12 mm. Disordered proliferative endometrium was seen in 33 patients and the endometrial thickness ranged between 12 mm and 14 mm. Menorrhagia (heavy menstrual bleeding) was present in 23 patients with secretory endometrium. Menorrhagia (heavy menstrual bleeding) was present in 23 patients with secretory endometrium.

Conclusion: There is a significant association between the clinical pattern of bleeding with ultrasound profile and histopathology in women with perimenopausal AUB.

Aim: To evaluate the effectiveness of simultaneous TAVI and coronary stenting in elderly and old patients with AVAS and CAD at high surgical risk. Methods: The study comprised 121 patients who underwent TAVI. They were assigned to two groups: I–patients who underwent TAVI with simultaneous coronary stenting (n = 30); II–patients with AVAS without severe stenotic changes in the coronary arteries. They underwent only TAVI (n = 91). The in-hospital period and the mid-term results have been studied. Results: The success of simultaneous TAVI and PCI was 100%. There were no intra- or perioperative deaths, acute myocardial infarction, acute brain stroke, or acute renal failure requiring dialysis. During the 6-month followup, one patient died from cancer. There were no other serious complications. The left bundle branch block occurred in 23.3% of cases and regurgitation (leakage) on the aortic valve in 6.6% of cases. Conclusion: Simultaneous TAVI and coronary stenting in elderly and old patients with severe aortic stenosis and CAD are feasible and safe. Within the first 30 days after the procedure, there were no significant differences in mortality and severe complication rates between the two groups.
