Foundations of Oral Medication Administration

The oral route is one of the most common and convenient methods for administering medications. It involves delivering drugs through the mouth, which are then absorbed into the bloodstream via the gastrointestinal tract. Understanding the physiological processes involved and the factors influencing drug absorption is crucial for healthcare providers.

Pharmacokinetics and Absorption: Medications taken orally undergo several stages, including:

• Liberation: The drug is released from its dosage form.
• Absorption: The drug moves from the gastrointestinal tract into the bloodstream.
• Distribution: The drug is transported throughout the body to its target sites.
• Metabolism: The drug is broken down, primarily in the liver.
• Excretion: The drug and its metabolites are eliminated from the body, mainly through the kidneys.

Factors affecting absorption include:

• Gastric pH: The acidity or alkalinity of the stomach can affect the breakdown and absorption of drugs.
• Gastric emptying time: The rate at which the stomach empties its contents into the small intestine can influence how quickly a drug is absorbed.
• Intestinal motility: The movement of the intestines affects the transit time of the drug, influencing absorption.
• Presence of food: Food can either enhance or inhibit drug absorption depending on the medication.
• Drug formulation: Different formulations (e.g., tablets, capsules, liquids) have varying rates of absorption.

Types of Oral Medications: Oral medications come in various forms, each with specific considerations:

• Tablets: Solid dosage forms that vary in shape, size, and coating.
• Capsules: Gelatin shells containing powder or liquid medication.
• Liquids: Solutions, suspensions, and syrups.
• Sublingual and Buccal Tablets: Dissolve under the tongue or between the cheek and gum, respectively, allowing for rapid absorption.

Principles of Topical Medication Administration

Topical medications are applied directly to the skin or mucous membranes to treat localized conditions. These medications can come in various forms, including creams, ointments, lotions, gels, and patches. Effective topical administration requires an understanding of skin physiology and the factors influencing drug penetration.

Skin Physiology and Drug Penetration: The skin consists of three main layers:

• Epidermis: The outermost layer, providing a barrier against the environment.
• Dermis: The middle layer, containing blood vessels, nerves, and hair follicles.
• Hypodermis: The innermost layer, composed of fat and connective tissue.

Drug penetration through the skin is influenced by:

• Skin condition: Broken or inflamed skin can enhance absorption.
• Hydration: Moist skin allows for better penetration.
• Application technique: Proper application ensures adequate contact between the medication and the skin.
• Drug concentration: Higher concentrations can lead to greater absorption.
• Occlusion: Covering the treated area can increase hydration and enhance absorption.

Types of Topical Medications:

• Creams: Emulsions of oil and water, easily absorbed and suitable for moisturizing.
• Ointments: Oil-based formulations that provide a protective barrier and enhance drug penetration.
• Lotions: Water-based formulations that are less greasy and easy to apply over large areas.
• Gels: Water-based formulations that dry quickly and leave a thin film on the skin.
• Transdermal Patches: Adhesive patches that deliver a controlled dose of medication through the skin over an extended period.
