Phenobarbital Brand Name: Phenobarb
Generic Name: Phenobarbital Brand Name: Phenobarb What Is It Used For? Decreasing seizure activity in various types of seizures. Especially useful for controlling seizures in neonates and infants Given intravenously in the emergency department for status epilepticus. How Long Does The Oral Medicine Take to Work? 10-30 days What Are The Important Safety Concerns? When first starting the medicine, your child may be slightly drowsy and/or dizzy. Only adjust the dosage as recommended by your health care provider. They will usually increase this medication slowly to avoid side effects. Never increase the dosage more than once per week unless directed otherwise. Once you have started with one brand of the medication stay with it. Avoid switching between different brands. Check with your pharmacist before taking herbal medications and/or over-the- counter medications. They may have adverse effects if taken with anti-seizure medications. Do not stop taking this medication suddenly because this could result in seizures. It is important to keep a record of your child’s seizures and side effects to determine how well they are responding to the medication. Does My Child Need Bloodwork With This Medication? Routine blood work may be done to help determine the best dosage for your child, and also if they have side effects to the medication. If your child is required to have blood work it must be done BEFORE they get the medication. This is called a trough level. This level usually falls between 65 and 170. A blood test may be done before starting this medication to check your child’s liver function and blood counts. -

Disease/Medical Condition EPILEPSY Date of Publication: August 7, 2014 (also known as “seizure disorder”) Is the initiation of non-invasive dental hygiene procedures* contra-indicated? No Is medical consult advised? ...................................... No (assuming patient/client is already under medical care for epilepsy, which is well controlled) Is the initiation of invasive dental hygiene procedures contra-indicated?** No Is medical consult advised? ....................................... Possibly (e.g., if there is medication non-compliance) Is medical clearance required? .................................. Possibly (e.g., if there is significant risk of seizure; patient/ client should be seizure-free for several months to be considered controlled) Is antibiotic prophylaxis required? .............................. No Is postponing treatment advised? ............................... No (assuming patient/client is already under medical care for epilepsy, which is well controlled and for which there are no anticipated exacerbating factors in the office setting) Oral management implications Important considerations in the management of epileptic patients/clients are prevention of seizures in the dental chair and preparation for managing seizures if they occur. When a patient/client responds positively to questions about seizures/ epilepsy during health history taking, further information should be obtained. Based on the patient/client’s responses, the dental hygienist may choose to postpone treatment to avoid triggering a seizure in the dental chair. It is valuable for the dental hygienist to know what factors have the potential to exacerbate epileptic seizures in a particular patient/client in order that trigger stimuli can be avoided. The dental hygienist can reduce stress and anxiety by explaining procedures before starting. Bright light should be kept out of the patient/client’s eyes, and dark glasses may assist with this. -
Pentobarbital Sodium
PENTobarbital Sodium Brand names Nembutal Sodium Medication error Look-alike, sound-alike drug names. Tall man letters (not FDA approved) are recommended potential to decrease confusion between PENTobarbital and PHENobarbital.(1,2) ISMP recommends the following tall man letters (not FDA approved): PENTobarbital.(30) Contraindications Contraindications: In patients with known hypersensitivity to barbiturates or any com- and warnings ponent of the formulation.(2) If an allergic or hypersensitivity reaction or a life-threatening adverse event occurs, rapid substitution of an alternative agent may be necessary. If pentobarbital is discontinued due to development of a rash, an anticonvulsant that is structurally dissimilar should be used (i.e., nonaromatic). (See Rare Adverse Effects in the Comments section.) Also contraindicated in patients with a history of manifest or latent porphyria.(2) Warnings: Rapid administration may cause respiratory depression, apnea, laryngospasm, or vasodilation with hypotension.(2) Should be withdrawn gradually if large doses have been used for prolonged periods.(2) Paradoxical excitement may occur or important symptoms could be masked when given to patients with acute or chronic pain.(2) May be habit forming. Infusion-related Respiratory depression and arrest requiring mechanical ventilation may occur. Monitor cautions oxygen saturation. If hypotension occurs, the infusion rate should be decreased and/or the patient should be treated with IV fluids and/or vasopressors. Pentobarbital is an alkaline solution (pH = 9–10.5); therefore, extravasation may cause tissue necrosis.(2) (See Appendix E for management.) Gangrene may occur following inadvertent intra-arterial injection.(2) Dosage Medically induced coma (for persistently elevated intracranial pressure (ICP) or refractory status epilepticus): Patient should be intubated and mechanically ventilated. -

In this study, solubility measurements from undersaturated solutions are employed to investigate the solubility of the two most stable polymorphs of flufenamic acid (FFA forms I and III), tolfenamic acid (TA forms I and II), and the only known form of niflumic acid (NA). The solubility was measured from 278.15 to 333.15 K in four alcohols of a homologous series (methanol, ethanol, 1- propanol, n-butanol) using the polythermal method. It was established that the solubility of these compounds increases with increasing temperature. The solubility curves of FFA forms I and III intersect at ∼315.15 K (42 °C) in all four solvents, which represents the transition temperature of the enantiotropic pair. In the case of TA, the solubility of form II could not be reliably obtained in any of the solvents because of the fast solvent- mediated phase transformation. -
