Common Drugs Flashcards
Therapeutic class of oxytocin
oxytocics
Pharmacologic class of oxytocin
Exogenous hormones
Indications of oxytocin
- to induce or stimulate labor
- to reduce postpartum bleeding after exposure of placenta
- Incomplete,evitable or elective abortion
action of oxytocin
Causes potent and selective stimulation of uterine and mammary gland smooth muscle
Adverse reactions of oxytocin
maternal
CNS: subarachnoid hemorrhage, seizures, coma
CV: arrhythmia, hypertension, hypotension, tachycardia
GI: nausea, vomiting
GU: abruptio placentae, tetanic uterine contractions, postpartum hemorrhage, urine rupture, impaired uterine blood flow, pelvic hematoma, increased uterine motility
Hematologic: afribrinogenemia, possibly related to postpartum bleeding, pelvic hematoma
Others: anaphylaxis, death from oxytocin induced water intoxication, hypersensitivity reactions
adverse reactions
fetal or neonate
CNS: brain damage, seizures
CV: bradycardia, arrhythmia, PVCs
EENT: neonatal retinal hemorrhage
Hepatic: Neil jaundice
Other: low apgar scores at five minutes, death
Contraindications & Cautions of Oxytocin
- Do not use in patients allergic to oxytocin.
- Do not use if vaginal delivery is unsafe (e.g., placenta previa, cervical cancer, genital herpes, or transverse lie).
- Avoid in cases of fetal distress (unless delivery is immediate), prematurity, severe pregnancy complications, or overly strong uterine contractions.
- Use with caution in patients with previous cervical or uterine surgeries (like cesarean), invasive cervical cancer, multiple pregnancies, uterine infections, traumatic delivery, or an overly stretched uterus.
Nursing Considerations of Oxytocin
- Monitor closely during IV administration.
- Stop infusion if uterine overstimulation or fetal distress occurs.
- Watch for water intoxication (fluid overload, seizures).
Mefenamic Acid is used for?
used for short-term pain relief (up to 7 days) and primary dysmenorrhea (menstrual pain). It has anti-inflammatory, pain-relieving, and fever-reducing properties by inhibiting cyclooxygenase (COX) enzymes.
Indications for Mefenamic Acid
- rheumatoid arthritis, osteoarthritis, dysmenorrhea, and mild to moderate pain, inflammation, and fever.
- Used for patients 14 years and older when treatment does not exceed one week.
- Specifically for treating menstrual pain (primary dysmenorrhea).
Side effects/adverse effect of mefenamic acid
Side Effects of Mefenamic Acid:
Stomach Issues:
Nausea, vomiting
Diarrhea, stomach pain
Indigestion, constipation
Ulcers or bleeding in the stomach (rare but serious)
Nervous System:
Headache, dizziness
Drowsiness, nervousness
Heart and Circulation:
High blood pressure
Swelling (fluid retention)
Increased risk of heart attack or stroke (especially with long-term use)
Kidneys:
Kidney problems
Blood in urine
Blood:
Anemia (low red blood cells)
Longer bleeding time
Skin:
Rash, itching
Rare but serious skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis)
Liver:
Liver problems (rare)
Allergic Reactions:
Severe allergic reactions (anaphylaxis)
Worsening of asthma
Hives
Cephalexin used for
Cephalexin is used to treat bacterial infections, including:
* Respiratory tract infections (like pneumonia and bronchitis)
* Urinary tract infections (UTIs)
* Skin and soft tissue infections (such as cellulitis)
* Bone infections (like osteomyelitis)
* Ear infections (otitis media)
It works by stopping the growth of bacteria.
Adverse reactions of Cephalexin
Common: Nausea, vomiting, diarrhea, stomach pain.
Serious: Allergic reactions (rash, swelling), seizures, superinfection, colitis.
Contraindications of Cephalexin:
- Allergy to cephalosporins or penicillin.
- Use cautiously in patients with seizure history, colitis, or kidney/liver problems.
Pregnancy & Breastfeeding: - Use only if necessary during pregnancy; may pass into breast milk.
Nursing Considerations for Cephalexin:
- Monitor for allergic reactions, diarrhea, or signs of superinfection.
- Treat streptococcal infections for at least 10 days.
Patient Teaching:
- Take as prescribed, even if feeling better.
- Report any side effects, especially rashes or diarrhea.
Cefuroxime is used for
Treats respiratory tract infections, skin infections, bone and joint infections (IV), urinary tract infections (UTIs), gynecologic infections, septicemia (IV), otitis media (ear infections) (PO), meningitis (IV), Lyme disease (PO), and for surgical infection prevention (IV).
