The Evaluation of the Efficacy and Safety of Midazolam Nasal Spray in Patients With Seizure Clusters: A Systematic Review and Meta-Analysis.

Midazolam nasal spray (MDZ-NS) is a new emerging rescue medication that suppresses epileptic seizures. Until now, few studies, pharmacokinetic (PK) and pharmacodynamic (PD) profiles, and clinical trials have shown that midazolam nasal spray could become an effective and promising alternative to conventional routes (intravenous {IV}/rectal). Therefore, we thought of conducting a systematic review and meta-analysis of midazolam (MDZ) to assess its potential outcomes. The analysis was also evaluated based on the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of midazolam nasal spray. A systematic literature search was carried out through various databases to identify studies of accounted outcomes of midazolam nasal spray (MDZ-NS). Randomized and other studies of patients (12 years or older) with seizure clusters (SCs) were included. A total of three full-text articles were considered for systematic review and meta-analysis as per the inclusion and exclusion criteria. The 5 mg MDZ-NS was observed to be equally safe as a placebo, and the risk ratio (RR) was 1.01 (95% confidence interval (CI): 0.67-1.53). After the administration of MDZ-NS, either the patients remained seizure-free for six hours or more or the seizure was terminated within 10 minutes and had no recurrence between 10 minutes and six hours. The risk ratio (RR) obtained was 1.54 (95% CI: 1.25-1.91). The result was statistically significant as a higher success rate was observed with the use of 5 mg midazolam nasal spray compared to placebo (p < 0.0001). Heterogeneity was not observed in the results of the included studies (inconsistency index {I2}: 0%). The present systematic review and meta-analysis demonstrated that 5 mg midazolam nasal spray was efficacious in treating patients with seizure clusters and is well-tolerated. Also, its use is relatively safe.

Efficacy, tolerability and safety of perampanel in population with pharmacoresistant focal seizures: A systematic review and meta-analysis.

BACKGROUND: Focal seizures are associated with various co-morbidities. Seizure disorders also affect the quality of life of the patients. A huge proportion of patients continue to have uncontrolled seizures despite the availability of numerous antiepileptic drugs. Novel therapeutic targets too, have failed to overcome this problem. Therefore, drugs acting on conventional targets are being explored. Perampanel is one such drug. The present study aimed to assess its efficacy, safety, and effect on quality of life and cognition in patients aged 12 years and above. METHODS: Database search was conducted using keywords perampanel, partial seizures and randomized controlled trials (RCTs). Single and double blinded RCTs were included in the analysis. The primary outcomes assessed were 50% responder rate and seizure freedom rates. Secondary outcomes assessed were Improvement in Clinical Global Improvement for Change (CGI-C), number of patients who experienced adverse events, number of patients who withdrew from trials, adverse drug reaction (ADR) profile from Vigibase, long term safety, quality of Life (QoL) assessment and cognitive assessment, especially in adolescents. The Risk ratios (RR) were calculated for these parameters. RESULTS: 24 full text articles were obtained out of a total 421 studies. From these seven double blind randomized controlled trials were included in the meta-analysis. Perampanel treated patients showed higher 50% responder rates than those treated with placebo. The Risk Ratios (RRs) were 1.39 [95% confidence interval (CI) 1.08-1.79], 1.83 [95% CI 1.51 - 2.22] and 1.81 [95% CI 1.45-2.27] for the 4 mg per day, 8 mg once daily and 12 mg once daily subgroups of perampanel respectively. The RRs for the seizure freedom rates were 4.52 [95% CI 1.30-15.73], 3.65 [95% CI 1.40-9.52] and 2.14 [95% CI 1.11-4.11] for 4 mg per day, 8 mg once daily and 12 mg once daily subgroups of perampanel respectively. There was a significantly higher risk of TEAEs with the 8 mg and 12 mg doses of perampanel as compared to that with placebo. Number of patients who withdrew from the trials due to adverse events was statistically significant in only the 12 mg subgroup of perampanel in comparison to that with placebo group. CONCLUSION: Perampanel was observed to be an effective add on drug for treating pharmacoresistant focal seizures. The patients achieved higher 50% response rates and freedom from seizures with its use. Tolerability of perampanel was more at lower doses.

Paxlovid: A promising drug for the challenging treatment of SARS-COV-2 in the pandemic era.

Coronavirus infection is a pandemic threat and the most dangerous disease of the 21st century. Despite the rigorous exertion of world-class researchers, there is no perfect cure for it. It has been seen in presently available studies that Paxlovid prevents the progression of diseases and reduces severity in patients tremendously who are at high risk of hospitalization and death. It is a safe oral antiviral drug and has the potential to treat infections from multiple corona variants including omicron which affects humans. Paxlovid is comparatively less expensive than other available effective medicines. Consequently, it reduces hospitalization and death and helps to plummet the economic burden on patients and the health-care system globally. This medicine is still under investigation, and numerous clinical trials are still underway. Its potential side effects are minor and well tolerated by research study participants. Studies show its benefits outweigh the risk, and it is an effective and good alternative for the treatment of coronavirus disease.

Naturalistic Evaluation of Prescription Pattern in Glaucoma Clinic of a Tertiary Care Hospital: A Developing Country's Perspective.

BACKGROUND: Glaucoma is a chronic, gradual and progressive eye disorder characterized by visual loss and involving the typical changes in optic nerves and associated structures. Currently, the mainstay treatment lies in the reduction of intraocular pressure (IOP) involving the usage of two or three medications concurrently. However, prescription pattern of antiglaucoma drugs remains largely unstudied so far. Therefore, there is a dire need of drug utilization studies to ensure rational prescribing for better treatment outcomes. AIM: This study was conducted to assess the prescription pattern in glaucoma patients to encourage rational use of drugs. MATERIALS AND METHODS: The pertinent data of confirmed glaucoma patients were entered in a predesigned case record form (CRF) including patient demographic details, type of glaucoma, number of drug prescribed, drug dosage and dosage formulation with prior patient consent, and finally, the data were analyzed using Microsoft Excel. RESULTS: A total of 247 glaucoma patients were recorded in the study. The mean SD number of drugs per prescription was 2.18 (1.68). Monotherapy was prescribed to 72 (29.15%) patients, and the most common monotherapy prescribed was timolol, whereas in fixed-dose combinations (FDCs), brimonidine and timolol FDCs were most commonly encountered. Furthermore, prescriptions consisting of generic drugs only and prescribed as per the National List of Essential Medicines (NLEM) were 48 (19.43%) and 41 (16.59%), respectively. CONCLUSION: This study showed the judicious use of medications in tune with principles of rational drug use in our center, and the rationale practices can be extended to the peripheral centers of the country for better drug utilization.
