Singulair Case Study

An 18-year-old Asian female presented for treatment at Missouri Southern State University Dental Hygiene clinic. The medical history reveals the patient had an ovarian benign tumor that was removed in 2003. The patient was under general anesthesia during the surgery and experienced no complications. Also, the patient has a diagnosis of low blood pressure. Another medical condition that the patient has is Dysautonomia, which is a dysfunction of the autonomic system. A contraindication for this condition would be epinephrine. The medications that the patient is currently taking are Trazodone, propranolol, singular, Zyrtec, Allegra, Rizatriptan, Aspirin, Licorice, Magnesium Gluconate, melatonin, and vitamin B-12.
Trazodone is a drug used for

The generic name for Singulair is Montelukast. Singulair is used to prevent symptoms and treat conditions such as asthma, exercise-induced bronchospasm, atopic dermatitis, hay fever and other seasonal allergies. Singulair is administered in the form of a tablet of various doses, which are taken orally. Singular prevents the constrictions of airways when an antigen is presented by binding to cysteinyl leukotriene receptors found in the airways. The binding of Singulair to these receptor sites inhibits edema of the airways, alteration in the inflammatory process and contraction of the smooth muscle (, 2017). Adverse reactions of Singulair include a headache, upset stomach, nausea, diarrhea, tooth pain, fatigue, nasal congestion, sore throat, and cough. Drug interactions with Singulair can include potent CYP450 inducers such as the drugs phenobarbital and rifampin (MPR, 2017) Significant effects on dental treatment include the awareness that this medication can induce dental pain as well as the tendency for increased bleeding and thrombocytopenia (Lexicomp dental reference library, 2016). Understanding how particular drugs affect oral health is imperative in the profession of dental hygiene. For patients that are taking Singulair, it is important to note increased bleeding could result from reduced platelet count. This is an important consideration for …show more content…
(Wynn et al., 2016). The mechanism of action of propranolol acts as a nonselective beta-adrenergic blocker. This blocks the response to beta and beta2 –adrenergic stimulation which can decrease heart rate. This can also decrease blood pressure and myocardial oxygen demand. Nonselective beta-blockers reduce portal pressure by splanchnic vasoconstriction. (Wynn et al., 2016). In simpler terms, propranolol reduces the need for oxygen by the heart muscle. (Ogbru). Indications for propranolol include high blood pressure, heart pain, abnormal rhythms of the heart, and some neurologic conditions. (Ogbru). As with many drugs, propranolol displays some contraindications. Some of which include: hypersensitivity to propranolol; congestive heart failure, unless the failure is due to the tachyarrhythmias being treated with propranolol; cardiogenic shock; severe sinus bradycardia; sick sinus syndrome; or heart block greater than first-degree; and bronchial asthma. Some common adverse effects after taking propranolol include cold extremities, angina, bradycardia, cardiogenic shock, hypotension, dizziness, fatigue, agitation, nightmares, drowsiness, amnesia, eczematous rash, changes in nails, erosive lichen planus, hyperkeratosis, pruritus, skin rash, diarrhea. Another adverse reaction to be noted is the
