Compounds Essential to Human Function01:25

Compounds Essential to Human Function

10.5K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

6.6K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Dose Size and Dosing Frequency: Determination Methods

328
Determining the optimal dose size and dosing frequency in pharmacotherapy is crucial for achieving therapeutic effectiveness while minimizing adverse effects. This article explores the methodologies employed in determining these parameters, focusing on their significance and interplay to tailor dosing regimens.Dose Size: Dose size refers to the amount of a drug administered in a single dose. It is determined based on the drug's pharmacodynamics and pharmacokinetics properties and...

Determination of Multiple Dosing Parameters: Loading and Maintenance Doses

250
A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

Rational Dosage Regimen: Maintenance Dose and Loading Dose

5.6K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

Drug Dosing: Infants and Children

324
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Summary

High-dose intramuscular thiamine shows promise for essential tremor treatment. This therapy may offer an effective, safe, and affordable alternative to current medications.

Area of Science:

  • Neurology
  • Nutritional Neuroscience

Background:

  • Essential tremor (ET) is a prevalent neurological disorder.
  • Current treatments like propranolol and primidone have limited efficacy and notable side effects.

Observation:

  • Two patients with essential tremor received intramuscular high-dose thiamine.
  • Significant and lasting symptom improvement was observed post-treatment.

Findings:

  • Intramuscular high-dose thiamine rapidly and effectively reduced essential tremor symptoms.
  • The treatment demonstrated a persistent positive effect with no significant adverse events.

Implications:

  • High-dose intramuscular thiamine presents a potentially superior therapeutic option for essential tremor.
