Preparation And Routes - NAPLEX

INH. This abbreviation indicates delivery via breathing in, targeting the lungs for local or systemic effects with rapid onset.

ID. This abbreviation denotes injection into the dermal layer of skin, commonly used for diagnostic tests like tuberculin screening.

SC (or SubQ). These abbreviations refer to injection beneath the skin into fatty tissue, ideal for slow absorption and self-administration.

IM. This abbreviation signifies injection into muscle tissue, suitable for drugs requiring sustained release or those irritating to veins.

Inhalation (pulmonary). MDIs deliver aerosolized medication directly to the lungs via inhalation, optimizing pulmonary absorption for respiratory conditions.

IV. This abbreviation represents direct injection into a vein, providing immediate systemic distribution and 100% bioavailability.

BUCC. This abbreviation indicates administration between the cheek and gum, allowing for mucosal absorption and often used for localized or systemic effects.

SL. This abbreviation denotes placement under the tongue for rapid absorption through the oral mucosa, bypassing first-pass metabolism.

PO (per os, by mouth). Derived from Latin 'per os' meaning by mouth, this abbreviation is universally used for medications administered orally to ensure systemic absorption via the gastrointestinal tract.

PV (per vaginam). Derived from Latin 'per vaginam,' this abbreviation denotes insertion into the vagina for local or systemic effects via mucosal absorption.

IV. Direct bloodstream entry avoids hepatic first-pass metabolism, unlike oral administration which passes through the liver before systemic circulation.

SL tablet. Placement under the tongue allows dissolution and absorption through highly vascular mucosa, providing quicker onset than enteric-coated forms which delay release.

Enteric-coated tablet. Special coating protects against stomach acid, ensuring disintegration in the alkaline intestinal environment for targeted delivery.

PR (per rectum). Derived from Latin 'per rectum,' this abbreviation is for suppositories or enemas, allowing absorption via rectal mucosa and partial bypass of first-pass metabolism.

AD right ear; AS left ear; AU both ears. Derived from Latin, these terms indicate aural administration to the right, left, or both ears for effective ear therapy.

OTIC (or AU/AD/AS for ears specified). These abbreviations are used for ear drops, with options to specify right, left, or both ears for localized auditory canal treatment.

OD right eye; OS left eye; OU both eyes. Rooted in Latin, these terms specify ocular administration to the right, left, or both eyes for targeted treatment of eye conditions.

OPH (or OU/OD/OS for eyes specified). These abbreviations are standard for eye drops or ointments, with specifics for right, left, or both eyes to ensure precise ocular delivery.

TOP. This abbreviation is used for applications to the skin surface, primarily for local effects without significant systemic absorption.

IN (intranasal). This abbreviation specifies administration into the nasal cavity, facilitating quick absorption through nasal mucosa for systemic or local action.

Extended-release tablet. Design controls drug release over time, and crushing disrupts this mechanism, potentially leading to dose dumping or reduced efficacy.

Transdermal (TD). Patches allow drug diffusion through skin into systemic circulation, designed for prolonged, controlled release over hours or days.

Ophthalmic. Formulations like drops or ointments target the eye directly, providing localized treatment for ocular conditions without systemic oral effects.

IV. Direct venous injection ensures immediate bioavailability and rapid therapeutic effects, critical in emergencies compared to slower muscular absorption.
