inhalation
medical tube
56
what does PO mean
by mouth
57
Common Forms of Medication: Tablets
Medication is compressed with binding substances and disintegrating agents; may have flavoring added to improve taste; used for oral, sublingual, and buccal routes.
Enteric-coated tablets have a special outer covering that delays absorption as it dissolves in the intestines.
58
Common Forms of Medication: Capsules
Medications are enclosed in cylindrical gelatin coatings.
Time-release capsules have medication particles encased in smaller casings that deliver medication over an extended period.
59
Common Forms of Medication: Powders
Ultrafine drug particles in a dry form; depending on the medication, may be inhaled, mixed with food, or dissolved in liquids immediately before administration.
60
Common Forms of Medication:Troches or lozenges
Medications prepared to dissolve in the mouth
61
Common Forms of Medication: Solutions
Medications already dissolved in liquid.
Syrups are mixed with sugar and water.
Suspensions are finely crushed medications in liquid.
Elixirs are medications dissolved in alcohol and water with glycerin or other sweeteners.
Drops are a sterile solution or suspension administered sublingually or directly into the eye, outer ear canal, or nose.
Injectable solutions are sterile suspensions supplied in ampules, vials, prefilled syringes, bags, or bottles.
62
Common Forms of Medication: Inhalants or sprays
Medications inhaled or sprayed into the mouth or nose; may have local or systemic effects.
Some are delivered in fixed doses.
63
Common Forms of Medication: Skin preparations
Ointments (spreadable, greasy preparations), creams (not greasy but used on skin only), and lotions (solutions or suspensions used on skin and not as sticky as creams or ointments).
Transdermal patches contain medication absorbed through the skin over an extended period.
64
Common Forms of Medication: Suppositories
Bullet-shaped gelatin tablets commonly administered rectally or vaginally depending on the medication. Urethral preparations are used for erectile dysfunction.
65
Medication Administration Routes advantages/ disadvantages: oral
advantages:Certain oral tablets formulated to dissolve on contact with the tongue
disadvantage: Inappropriate for patients with nausea or vomiting
contraindicated for patients with swallowing difficulty
Can irritate the gastrointestinal lining, have an unpleasant taste, or discolor teeth
Patient must be alert and oriented to safely administer
Cannot be used with simultaneous gastric suctioning or before various diagnostic or surgical procedures
Possible irregular or slow absorption
66
Medication Administration Routes advantages/ disadvantages: sublingual or buccal
advantages: As above plus more potent because the drug bypasses the liver and enters the bloodstream directly
disadvantages: May be inactivated by gastric juices if swallowed
67
Medication Administration Routes advantages/ disadvantages: Topical
advantages: Local effect with few side effects
disadvantages: Absorption may be irregular if skin breaks are present, and it may be slow
68
Medication Administration Routes advantages/ disadvantages: Transdermal
advantages: Prolonged systemic effects without gastrointestinal absorption problems
disadvantages: May leave residue on clothes or skin. May cause localized skin irritation.
69
Medication Administration Routes advantages/ disadvantages: Mucous membranes (eyes, ears, nose, vagina, rectum, ostomy)
advantages: Local effects to involved sites with systemic effects possible; readily absorbed; may be used if the oral route is contraindicated
disadvantages: Mucous membranes are highly sensitive to concentrated medications
Dose absorption may be unpredictable
Procedure may be messy
70
Medication Administration Routes advantages/ disadvantages: Inhalation
advantages: Rapid localized effect; may be administered to unconscious patients
disadvantages:May cause serious systemic effects; can be administered only through the respiratory system
71
Medication Administration Routes advantages/ disadvantages: Parenteral (intradermal, subcutaneous, IM, IV)
advantages: Can be used if the oral route is contraindicated; more rapid response than the oral or topical route; can be used for critically ill patients or for long-term therapy
IV route can decrease discomfort and can better control absorption if peripheral perfusion is compromised
disadvantages: Sterile technique must be used, as the skin barrier is compromised
More costly to formulate and administer; useful for small volumes only, except by IV route; affected by circulatory status; can produce patient anxiety
72
Intradermal
Shallow injection into the dermal layer just under the epidermis
73
Subcutaneous
