UNASSIGNED: There is evidence that vaginal cabergoline can help to prevent ovarian hyperstimulation syndrome. Therefore, the vaginal suppository may be a good choice because it can be administered directly into the vagina and has no adverse effects on the stomach. In this regard we developed a cabergoline suppository as an alternative to cabergoline tablets. Design-Expert was used to determine the most suitable concentrations of PEG 6000/400, and Tween 80 to obtain a stable suppository. Specific ratios of PEG6000/400 and Tween 80 were entered as factors, and release, melting time, and hardness were evaluated as responses. In addition, the final formulation was evaluated for weight changes, pH, drug content, degradation time, deformation time, in vitro drug release, DSC analysis, infrared spectroscopy, and stability properties.
UNASSIGNED: The suppositories were all smooth and white. They all had a weight that averaged less than 5 %. The formulations showed a pH between 6 and 6.5. The active ingredient content ranged between 79.666 ± 8.54 % and 99.67 ± 6.55 %. Suppository stiffness was between 2.74 ± 0.04 and 4.20 ± 0.03. The decomposition time of the suppositories varied between 11.25 ± 0.15 to 20.19 ± 0.08 min. The deformation time was between 26.11 ± 0.06 to 38.59 ± 0.47 min. Cabergoline content was released over 45 min from formulations of F10 (∼46 %), F2 (∼64 %), F6 (∼69 %), F4 (∼79 %), F1 (∼88 %), and F7 (∼93 %). However, other formulations released more than 95 % within 45 min.
UNASSIGNED: All variables except melting time significantly affected our responses. In vitro studies have indicated that the optimized cabergoline formula could be an excellent alternative to cabergoline oral formulations.

Mesalazine (MSZ) suppositories are a first-line medication for the localized treatment of ulcerative colitis (UC). However, the frequent defecation of patients with UC influences the retention of the suppository in the rectum and multiple doses have to be applied. Here, a mesalazine hollow suppository (MHS) is developed using three-dimensional (3D) printing. The MHS is composed of an inner supporting spring and an outer MSZ-loaded curved hollow shell. Springs were prepared using fused deposition modeling (FDM) 3D printing with thermoplastic urethane filaments, followed by splitting. The optimal parameters, including elasticity, filament diameter, spring inner diameter, and filament distance, were screened. The shell was prepared by FDM 3D printing utilizing MSZ, polyvinyl alcohol, and polyethylene glycol, which were assembled with springs to obtain FDM 3D-printed MHS (F-MHS); if 3D-printed metal molding was used in preparing shell, mold-formed MHS (M-MHS) was obtained. The F-MHS exhibited faster MSZ release than the M-MHS; therefore, the molding method is preferable. The inserted M-MHS was retained in the rat rectum for 5 h without affecting defecation. M-MHS alleviated tissue damage of UC rats and reduced inflammation with low levels of myeloperoxidase and proinflammatory cytokines. Personalized MHS is a promising medication for the localized treatment of UC.

Lozenge is one of the traditional dosage forms of Chinese medicine. It has been recorded in traditional Chinese medical classics of all dynasties since the Eastern Han Dynasty and has been developing and evolving continuously. The unique pharmaceutical methods and application scope are the driving force of its emergence, existence, and development. Up to now, lozenge has been included in the Chinese Pharmacopoeia as an independent dosage form. Lozenge has been endowed with new meaning by modern Chinese medicine pharmaceutics, which is worth tracing origin and exploring value. The present study reviewed the origin and development of lozenge, compared lozenge with other similar dosage forms, analyzed the characteristics of modern and ancient dosage forms of lozenge, and discussed the development prospect and potential of lozenge in combination with the demand development of modern Chinese medicine preparation, so as to provide references for expanding the modern application of lozenge.

Patients undergoing vaginal hysterectomy with native tissue pelvic reconstruction typically have low pain levels overall in the postoperative period. Notwithstanding, pain control immediately after surgery may be more challenging and a barrier to same-day discharge. Intrarectal diazepam has been used for acute and chronic pelvic pain and has a pharmacokinetic profile ideal for intermittent use. However, its use has not been investigated after the surgical intervention.
This study aimed to evaluate the effect of diazepam rectal suppositories on early postoperative pain after hysterectomy and vaginal reconstruction for pelvic organ prolapse.
This was a double-blind, randomized, placebo-controlled trial comparing postoperative pain scores after vaginal hysterectomy with native tissue prolapse repairs. Patients were randomized to receive either an intrarectal 10-mg diazepam suppository or an identical placebo. Moreover, the participants completed the questionnaires at baseline, the morning of postoperative day 1, and 2 weeks after the operation. Surveys included visual analog scales for pain, a validated Surgical Satisfaction Questionnaire, and queries regarding medication side effects and postoperative recovery. The primary outcome was pain scores based on a visual analog scale approximately 3 hours after surgery. The secondary outcomes included total morphine equivalents after surgery, patient satisfaction with pain control, same-day discharge outcome, and overall satisfaction. The chi-square, Fisher exact, and Mann-Whitney tests were used. Based on a 10-mm difference in postoperative vaginal pain using the visual analog scale, sample size was calculated to be 55 patients in each arm to achieve 80% power with an alpha of.05.
From February 2020 to August 2021, 130 participants were randomized. Of those participants, 7 withdrew, and 123 were analyzed: 60 in the diazepam group and 63 in the placebo group. The median age was 65 years (interquartile range, 27-80), the median body mass index was 27.9 kg/m2 (interquartile range, 18.70-45.90), and 119 of 123 participants (96.7%) were White. There was no difference in the baseline characteristics, prolapse stage, or types of procedures performed between groups. Most participants had concurrent uterosacral ligament suspension with anterior and posterior repairs. Of note, 50 of 123 participants (41%) had midurethral slings. Moreover, 61 of 123 participants (50%) were discharged on the day of surgery. There was no difference in the primary outcome of vaginal pain 3.5 to 6.0 hours postoperatively (25 vs 21 mm; P=.285). In addition, the amount of rescue narcotics used in the immediate postoperative period (19.0 vs 17.0 MME; P=.202) did not differ between groups. At 2-weeks postoperatively, patients in the placebo group reported higher satisfaction with pain control in the hospital (31 vs 43 mm; P=.006) and pain control at home (31 vs 42 mm; P=.022). No difference was noted between same-day discharges and those who were admitted overnight.
The placement of a 10-mg diazepam rectal suppository immediately after pelvic reconstructive surgery did not improve pain or narcotic usage in the early postoperative period. Although the placebo group reported slightly higher satisfaction with pain control 2 weeks after surgery, overall pain levels were low. Therefore, we do not believe that the addition of diazepam to the postoperative regimen is warranted.

To prospectively assess the efficacy and safety of Lactobacillus vaginal suppositories for the prevention of recurrent cystitis.
In this single-arm, open-label, phase II clinical trial, participants used vaginal suppositories containing the GAI 98322 strain of Lactobacillus crispatus for 1 year either every 2 days or three times per week. The primary end-point was the response rate, as assessed by the number of episodes of recurrent cystitis during the year of administration. The secondary end-points were the response rate, as assessed by episodes of recurrent cystitis during the 1 year after completion of the administration period; the total number of episodes of recurrent cystitis before, during and after administration; adverse events; and changes in urine bacteria and the vaginal microbiome.
A total of 28 women were enrolled, and 21 completed the study. A total of 18 patients achieved an effective response (86%) during administration. The suppressive effects of Lactobacillus vaginal suppositories on episodes of cystitis continued up to 1 year after the last suppository was administered. There was a significant reduction in the mean number of episodes of cystitis, both during and after administration of Lactobacillus vaginal suppositories. No treatment-related adverse events were observed. Amplicon sequencing analysis of the vaginal microbiome showed that Lactobacillus species colonized the vagina during the periods when episodes of cystitis were absent.
Vaginal suppositories containing the GAI 98322 strain of Lactobacillus crispatus effectively prevent episodes of recurrent cystitis, both during administration and for at least 1 year after administration.

BACKGROUND: Fever is the most common complaint among the children admitted to health care centers. The aim of this study was to compare the anti-pyretic effect of diclofenac and high dose acetaminophen suppository in 1 to 6 years old children.
METHODS: This double-blind clinical trial study was performed on 1-6-year-old children hospitalized in 17th Shahrivar Teaching Hospital, Rasht, Iran. Children were divided into two groups of 45 using a block randomization design. The first group received a high dose of acetaminophen suppository at a dose of 30 mg/kg and the second group received a diclofenac suppository at a dose of 1 mg/kg. The rectal temperature of the patients was measured using a digital thermometer at the time of drug administration, and one and three hours after that.
RESULTS: 90 children were studied in two groups of 45 each. Temperature changes in the diclofenac group were significantly greater than the acetaminophen group, so from zero to 3 hours after administering diclofenac, the temperature decreased to 1.76±0.95°C. This reduction was lower in acetaminophen group (1.26±0.49°C, P=0.019).
CONCLUSIONS: Both acetaminophen and diclofenac suppositories significantly reduced the rectal temperature. However, the effect of rectal diclofenac on reducing temperature is more than rectal acetaminophen.

Patients with ulcerative colitis (UC) limited to distal segments of the colon and rectum are often poorly represented in large clinical therapeutic trials, yet they constitute up to two-thirds of all UC patients. The propensity of UC to be most severe distally has also resulted in many oral or systemic therapies with lower levels of therapeutic success and mucosal healing in the distal regions of the colon. Topically administered mesalamine and corticosteroid agents have been utilized for decades in patients with distal UC but are often poorly accepted by patients and their prescribing physicians due to difficulties in administration and embarrassment. Formulation advances in the mesalamine preparations have led to the addition of topical 5-aminosalicylic acid (5-ASA) foams and gels to the existing options of liquid enemas and suppositories. Comparable advances in the use of topical corticosteroids have also taken advantage of the development of topical budesonide and similar safer corticosteroid preparations that promise clinical efficacy while delivering fewer systemic corticosteroid side effects. Combination therapy with oral and topical 5-ASA agents, or with topical 5-ASA and topical corticosteroid compounds, has further expanded the armamentarium for prescribers. Novel topical applications of currently existing therapies such as tacrolimus and cyclosporine show varying degrees of promise; the growing area of biologic and novel small molecules raises the possibility of a new wave of topically applied therapies for patients with distal UC and ulcerative proctitis.

BACKGROUND: Uncomplicated infections such as candidiasis, bacterial vaginosis (BV), or trichomoniasis are easy to diagnose and treat. However, about 8% of patients will have a more complicated course with failure to respond to treatment or rapid recurrence of symptoms. There are many suggestions in Traditional Persian Medicine like myrtle (Myrtus communis L.) and oak gall (Quercus infectoria G.Olivier) for treatment of vaginitis.
OBJECTIVE: A clinical trial was designed to assess the efficacy of a novel herbal suppository, containing myrtle and oak gall (MOGS) in treatment of vaginitis.
METHODS: In a parallel randomized clinical trial, 120 women with vaginitis were randomly assigned to MOGS, metronidazole, or placebo. Formulation was simulated from traditional Persian manuscripts and MGOS was prepared after pharmaceutical optimization processing as well as quantification of gallic acid by HPLC. The study was double-blind for MOGS and placebo and single-blind for metronidazole group.
RESULTS: MOGS effectively improved vaginal discharge (p = 0.024 for BV and 0.018 for trichomoniasis) and pH (compared to placebo (p = 0.013) and metronidazole (p = 0.001)). Both MOGS and metronidazole could reverse whiff test. Metronidazole was the best medication for making Nugent score negative (p = 0.005) as well as the best therapy according to laboratory findings to treat BV in comparison with placebo (p = 0.021). While for trichomoniasis, MOGS could improve the disease more successfully (p = 0.001). Both MOGS and metronidazole treated mixed vaginitis (p = 0.002).
CONCLUSIONS: MOGS would be a chance for developing new treatment for trichomoniasis.

Camptothecin is known for its potent anticancer activity. However, its optimal activity is reduced due to its low solubility and stability in biological media.
The aim of the present study is to design and characterize a Camptothecin (CPT) suppository formulation.
Rectal suppositories of camptothecin alone, encapsulated with Cyclodextrin (CD) and in the ternary system (CPT encapsulated with cyclodextrin and dispersed in Polyethylene Glycol (PEG) 6000) were prepared using various hydrophobic and hydrophilic polymeric bases as semi-synthetic glyceride (Suppocire® AM Pellets) and Polyethylene Glycols (PEGs) mixtures. Formulations were evaluated by various parameters like weight variation, drug content, hardness and liquefaction time. In vitro release study was performed in USP type I apparatus using phosphate buffer pH 7.2 as dissolution media.
Suppositories were within the permissible range of all physical parameters. In vitro drug released from water soluble base (PEG) was greater than that from oil soluble base with ninety percent (90%) of drug dissolution. It was also established that drug release from various formulations was by diffusion mechanism, according to the Higuchi\'s equation.
This new formulation offers a new approach to colorectal cancer treatment by offering an alternative and simple drug administration route.
