Treatment Summary

Cyclobenzaprine is a muscle relaxant drug first created in 1961 and approved for human use in 1977. It is often prescribed as a short-term treatment for muscle spasms caused by injuries or similar conditions. It is similar to the antidepressant amitriptyline, but with a single double bond difference. Cyclobenzaprine has remained popular since it was approved and is used to reduce muscle spasms.

How Cyclobenzaprine Hydrochloride Affects Patients

Cyclobenzaprine is a muscle relaxer that affects the brainstem to reduce muscle tension. It is short-acting, with effects lasting 4-6 hours. Taking cyclobenzaprine with other medications that affect serotonin can lead to a condition called serotonin syndrome, which can cause changes in mental status, physical instability, and digestive symptoms. If any of these occur while taking this drug, it should be stopped immediately.

How Cyclobenzaprine Hydrochloride works in the body

We don't know exactly how cyclobenzaprine works in the body, but research suggests it has an effect on the brainstem. This could reduce the activity of certain motor neurons, which could explain the muscle relaxing effects. It might also work by inhibiting serotonin pathways in the spinal cord.

Cyclobenzaprine Hydrochloride Toxicity & Overdose Risk

Cyclobenzaprine is toxic when taken in large amounts. The toxic dose in mice and rats is 338 mg/kg and 425 mg/kg, respectively. Overdosing on cyclobenzaprine can lead to drowsiness, rapid heartbeat, trembling, agitation, difficulty walking, stomach upset, confusion, and hallucinations. In severe cases, it can cause cardiac arrest, difficulty breathing, seizures, or a dangerous condition called neuroleptic malignant syndrome. If someone overdoses on cyclobenzaprine, it is important to contact a poison control center. Treatment usually involves removing the drug from the body, closely monitoring the heart

"The text is describing symptoms of a medical condition. The symptoms include:convulsions (seizures), drowsiness (severe), dry, hot, flushed skin, fast or irregular heartbeat, hallucinations (seeing, hearing, or feeling things that are not there), increase or decrease in body temperature, troubled breathing, unexplained muscle stiffness."

Answered by AI

Is cyclobenzaprine hydrochloride a narcotic?

"Is Flexeril a narcotic? Flexeril is not a narcotic drug or an opioid, and is not controlled under the Controlled Substances Act (CSA). However, since Flexeril has properties that suppress pain, people may overuse it to amplify those feelings."

Answered by AI

Is cyclobenzaprine hydrochloride the same as Flexeril?

"This medication is approved in the United States for use as a muscle relaxant. The brand names are Flexeril and Amrix, and it is also available as a generic in 5, 7.5, and 10 mg tablets. It is intended for short-term use, generally no longer than 2-3 weeks. The usual starting dose is 5 mg, three times per day."

SBS-147 Safety Study

18 - 55
All Sexes
Cypress, CA

This study is part of the HEAL Initiative supported by the NIH. The purpose of this study is to learn how safe the study drug, SBS-147, is and how people's bodies respond to and process it. Researchers will also look for any side effects that may occur when taking SBS-147. Some participants will receive SBS-147, and others will receive a placebo, which looks the same but does not contain any medicine. This helps researchers fairly compare results. The study includes two parts: Single-Dose Group, where Participants receive SBS-147 or placebo one time. Multiple-Dose Group, where Participants receive SBS-147 or placebo once or twice daily for 7 days.

Lidocaine Infusions for Postoperative Pain

18+
All Sexes
Nashville, TN

The goal of this single-center, pragmatic, randomized, blinded, placebo-controlled trial is to evaluate the impact of intravenous (IV) lidocaine within the existing Enhanced Recovery After Surgery (ERAS)program on outcomes in patients after major abdominal surgery. The main questions the trial aims to answer are: The primary hypothesis is that utilization of IV lidocaine as part of a perioperative multimodal pain regimen will result in a reduction in hospital Case Mix Index-Adjusted Resource Length of Stay (CARLOS). The secondary hypotheses are that lidocaine infusion will result in a reduction in total inpatient opioid consumption (oral morphine milligram equivalents, oMMEs) and pain scores, and improved surgical outcomes (including return of bowel function, ileus, nausea, rapid responses called, surgical site infections, and ICU transfers), while also having minimal incidence of side effects (including double/blurry vision, tinnitus, sedation, and adverse events requiring early cessation).

Guided Imagery Therapy for Abdominal Pain

7 - 12
All Sexes
Austin, TX

Chronic abdominal pain is common among children, and the majority of cases are attributed to functional abdominal pain disorders. One approach to treating these disorders is by using psychological therapies. This clinical trial aims to see how well pre-recorded guided imagery therapy sessions help children's abdominal pain when delivered via a mobile application (app) on a smartphone or tablet. Participants will complete a baseline abdominal pain and stooling diary to determine eligibility, as well as other surveys. Eligible participants will be given access to the guided imagery therapy mobile application. This intervention asks participants to listen to a 10- to 15-minute GIT session 5 out of 7 days per week for 8 weeks, in addition to their usual care for their abdominal pain. Then, participants will complete another abdominal pain and stooling diary, along with other psychometric surveys, at the end of this intervention period. Participants will also collect another diary and surveys 3 months post-treatment.
