Article Abstract
Objective: Clonidine hydrochloride is an antihypertensive, centrally acting α2 adrenergic agonist with various pediatric indications. For pediatric patients, 20-mcg clonidine hydrochloride capsules can be compounded from commercial tablets or from a pre-compounded titrated powder. These methods should be compared to ensure the best quality for the high-risk patients, and a beyond-use date should be established.
Methods: Eight experimental batches were made from commercial tablets and 8 were made from microcrystalline cellulose (MCC)-based titrated powders. Quality controls were performed to determine the best compounding protocol. Stability study was conducted on capsules compounded with the best method.
Results: Of 8 batches manufactured from commercial tablets, 7 were compliant for both clonidine mean content and content uniformity, whereas 7 of 8 batches manufactured from titrated powders were not. A clonidine loss during compounding was evidenced by surface sampling analyses. Clonidine hydrochloride 20-mcg capsules' mean content remained higher than 90% of initial content for 1 year when stored at 25°C with 60% relative humidity and protected from light.
Conclusions: Commercial tablets should be preferred to 1% clonidine hydrochloride and MCC titrated powder made from the active pharmaceutical ingredient. Twenty-microgram clonidine hydrochloride capsules made from commercial tablets are stable for 1 year when stored under managed ambient storage condition.

Schizophrenia is a complex psychiatric disorder characterized by positive, negative, and general psychopathological symptoms. While antipsychotic drugs are effective for positive symptoms, they provide limited benefit for negative symptoms, which are often persistent and strongly associated with functional disability. Additionally, up to 30% of patients exhibit resistance to current treatments, including clozapine.

Background: Many traumatic brain injury (TBI) treatment protocols, including the Lund concept, advocate the highest point of the subarachnoid space (typically the vertex) as the zero-reference point for intracranial pressure (ICP) and the level of the right atrium as the zero-reference point for mean arterial blood pressure (MAP). In 2017, at the Department of Neurosurgery in Lund, Sweden, the zero-reference points for ICP and MAP were both changed to the external auditory meatus (EAM), thus altering the calculated cerebral perfusion pressure (CPP) levels. We hypothesized that the ICP and MAP levels obtained from the different zero-reference points resulted in altered neurocritical care management and/or patient outcome.

Treatment of Menopausal Symptoms When Hormone Therapy Is Contraindicated.

Menopausal symptoms, particularly vasomotor symptoms (VMS) and genitourinary syndrome of menopause (GSM), significantly affect women's quality of life (QoL). While menopausal hormone therapy (MHT) is the most effective treatment, contraindications such as estrogen-sensitive cancers and thromboembolic conditions limit its use for many women. This review explores alternative nonhormonal treatments, including pharmacological options like selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, gabapentin, clonidine, and neurokinin receptor antagonists (e.

Optimal neuraxial anesthesia for cesarean delivery requires a thorough understanding of patient, obstetrical, surgical, and anesthesia-related factors which can impact pain during and after cesarean delivery. While not all cesarean deliveries are the same from an obstetrical standpoint, not all anesthetics provide the same degree of anesthetic blockade and postcesarean analgesia; therefore, context is crucial to provide patients with a safe and pain-free experience. Communication between obstetrical and anesthesia teams is key to ensure that the anesthetic approach is tailored to the clinical scenario, particularly if emergency cesarean delivery is needed, and follows best practices for cesarean delivery anesthesia.
