==Overview==
The majority of cases of pharyngitis are self-limited and only require symptomatic therapy.
The majority of cases of [[pharyngitis]] are [[self-limited]] and only require [[symptomatic therapy]]. Accurate diagnosis of [[streptococcal]] [[pharyngitis]] followed by appropriate [[antimicrobial]] therapy is important for the prevention of [[acute rheumatic fever]], for the prevention of [[suppurative]] complications (e.g, [[peritonsillar abscess]], [[cervical]] [[lymphadenitis]], [[mastoiditis]], and, possibly, other invasive infections), to improve clinical symptoms and signs, for the rapid decrease in [[contagiousness]], for the reduction in transmission of [[Group A streptococcal|GAS]] to family members, classmates, and other close contacts of the patient to allow for the rapid resumption of usual activities; and for the minimization of potential adverse effects of inappropriate [[antimicrobial]] therapy.

* Bacterial pharyngitis is common among young children and adolescents. Group A beta-hemolytic streptococcus (GAS) is the most common cause and always requires antibiotic therapy to prevent suppurative and certain non-suppurative complications.
 
===Supportive Therapies===
====Topical therapy====
Oral rinses were more effective in treating conditions affecting oral cavity and base of the tongue whereas sprays were more effective in coating the posterior pharynx and hence they were used to treat posterior pharynx conditions.<ref name="Patel-1999">{{Cite journal  | last1 = Patel | first1 = SK. | last2 = Ghufoor | first2 = K. | last3 = Jayaraj | first3 = SM. | last4 = McPartlin | first4 = DW. | last5 = Philpott | first5 = J. | title = Pictorial assessment of the delivery of oropharyngeal rinse versus oropharyngeal spray. | journal = J Laryngol Otol | volume = 113 | issue = 12 | pages = 1092-4 | month = Dec | year = 1999 | doi =  | PMID = 10767923 }}</ref>
=====Oral rinses=====
*Salt water gargles which have been used since a long time have not shown any benefit in releiving  throat pain . It is still used as it has minimal side effects.
*[[Lidocaine]], [[Diphenhydramine]] and [[Maalox]]  ([[Aluminium hydroxide]], [[magnesium hydroxide]] and simethicone) have shown to be helpful. This combination can be used to treat Coxsackie  A or B infection or herpes simplex. Avoid using the lidocaine over its recommended use.<ref name="Hess-1988">{{Cite journal  | last1 = Hess | first1 = GP. | last2 = Walson | first2 = PD. | title = Seizures secondary to oral viscous lidocaine. | journal = Ann Emerg Med | volume = 17 | issue = 7 | pages = 725-7 | month = Jul | year = 1988 | doi =  | PMID = 3382075 }}</ref><ref name="Gonzalez del Rey-1994">{{Cite journal  | last1 = Gonzalez del Rey | first1 = J. | last2 = Wason | first2 = S. | last3 = Druckenbrod | first3 = RW. | title = Lidocaine overdose: another preventable case? | journal = Pediatr Emerg Care | volume = 10 | issue = 6 | pages = 344-6 | month = Dec | year = 1994 | doi = | PMID = 7899121 }}</ref>
*[[Benzydamine]] hydrochloride rinses have shown to be help reduce the pain in a few cases. However, they are used more frequently to treat radiation mucositis.<ref name="Turnbull-1995">{{Cite journal  | last1 = Turnbull | first1 = RS. | title = Benzydamine Hydrochloride (Tantum) in the management of oral inflammatory conditions. | journal = J Can Dent Assoc | volume = 61 | issue = 2 | pages = 127-34 | month = Feb | year = 1995 | doi =  | PMID = 7600413 }}</ref><ref name="Passàli-2001">{{Cite journal  | last1 = Passàli | first1 = D. | last2 = Volonté | first2 = M. | last3 = Passàli | first3 = GC. | last4 = Damiani | first4 = V. | last5 = Bellussi | first5 = L. | title = Efficacy and safety of ketoprofen lysine salt mouthwash versus benzydamine hydrochloride mouthwash in acute pharyngeal inflammation: a randomized, single-blind study. | journal = Clin Ther | volume = 23 | issue = 9 | pages = 1508-18 | month = Sep | year = 2001 | doi =  | PMID = 11589263 }}</ref><ref name="Wethington-1985">{{Cite journal  | last1 = Wethington | first1 = JF. | title = Double-blind study of benzydamine hydrochloride, a new treatment for sore throat. | journal = Clin Ther | volume = 7 | issue = 5 | pages = 641-6 | month =  | year = 1985 | doi =  | PMID = 3902241 }}</ref><ref name="Epstein-2001">{{Cite journal  | last1 = Epstein | first1 = JB. | last2 = Silverman | first2 = S. | last3 = Paggiarino | first3 = DA. | last4 = Crockett | first4 = S. | last5 = Schubert | first5 = MM. | last6 = Senzer | first6 = NN. | last7 = Lockhart | first7 = PB. | last8 = Gallagher | first8 = MJ. | last9 = Peterson | first9 = DE. | title = Benzydamine HCl for prophylaxis of radiation-induced oral mucositis: results from a multicenter, randomized, double-blind, placebo-controlled clinical trial. | journal = Cancer | volume = 92 | issue = 4 | pages = 875-85 | month = Aug | year = 2001 | doi =  | PMID = 11550161 }}</ref><ref name="Kim-1986">{{Cite journal  | last1 = Kim | first1 = JH. | last2 = Chu | first2 = FC. | last3 = Lakshmi | first3 = V. | last4 = Houde | first4 = R. | title = Benzydamine HCl, a new agent for the treatment of radiation mucositis of the oropharynx. | journal = Am J Clin Oncol | volume = 9 | issue = 2 | pages = 132-4 | month = Apr | year = 1986 | doi =  | PMID = 3521255 }}</ref>
 
=====Sprays=====
*Topical anesthetic sprays have been used in the past to treat pharyngitis , however their effect is not signigficant . They may also cause a few allergic reactions and side effects like methemoglobinemia and hence should not be used in children.
*Chlorhexidine /benzydamine sprays are more effective in alleviating symptoms of acure viral pharyngitis and group A streptococcal pharyngitis.<ref name="Cingi-2011">{{Cite journal  | last1 = Cingi | first1 = C. | last2 = Songu | first2 = M. | last3 = Ural | first3 = A. | last4 = Erdogmus | first4 = N. | last5 = Yildirim | first5 = M. | last6 = Cakli | first6 = H. | last7 = Bal | first7 = C. | title = Effect of chlorhexidine gluconate and benzydamine hydrochloride mouth spray on clinical signs and quality of life of patients with streptococcal tonsillopharyngitis: multicentre, prospective, randomised, double-blinded, placebo-controlled study. | journal = J Laryngol Otol | volume = 125 | issue = 6 | pages = 620-5 | month = Jun | year = 2011 | doi = 10.1017/S0022215111000065 | PMID = 21310101 }}</ref><ref name="Cingi-2010">{{Cite journal  | last1 = Cingi | first1 = C. | last2 = Songu | first2 = M. | last3 = Ural | first3 = A. | last4 = Yildirim | first4 = M. | last5 = Erdogmus | first5 = N. | last6 = Bal | first6 = C. | title = Effects of chlorhexidine/benzydamine mouth spray on pain and quality of life in acute viral pharyngitis: a prospective, randomized, double-blind, placebo-controlled, multicenter study. | journal = Ear Nose Throat J | volume = 89 | issue = 11 | pages = 546-9 | month = Nov | year = 2010 | doi =  | PMID = 21086279 }}</ref>


=====Lozenges=====
*As [[viral]] infections are the most common causes of [[pharyngitis]] in children, most patients do not require treatment and only need [[supportive care]].<ref name="pmid8637780">Bisno AL (1996) [https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&retmode=ref&cmd=prlinks&id=8637780 Acute pharyngitis: etiology and diagnosis.] ''Pediatrics'' 97 (6 Pt 2):949-54. PMID: [https://pubmed.gov/8637780 8637780]</ref>
*Medical throat lozenges help reducing the duration of symptoms and also provide with some sympotomatic relief. They do come with a few side effects similiar to sprays like methemoglobinemia. They are not recommended for children as there is a risk of choking  Lozenges containing antisepotics, menthol , anesthetics and antiflammatory agents have been used.<ref name="Bisno-2001">{{Cite journal  | last1 = Bisno | first1 = AL. | title = Acute pharyngitis. | journal = N Engl J Med | volume = 344 | issue = 3 | pages = 205-11 | month = Jan | year = 2001 | doi = 10.1056/NEJM200101183440308 | PMID = 11172144 }}</ref><ref name="Watson-2000">{{Cite journal  | last1 = Watson | first1 = N. | last2 = Nimmo | first2 = WS. | last3 = Christian | first3 = J. | last4 = Charlesworth | first4 = A. | last5 = Speight | first5 = J. | last6 = Miller | first6 = K. | title = Relief of sore throat with the anti-inflammatory throat lozenge flurbiprofen 8.75 mg: a randomised, double-blind, placebo-controlled study of efficacy and safety. | journal = Int J Clin Pract | volume = 54 | issue = 8 | pages = 490-6 | month = Oct | year = 2000 | doi =  | PMID = 11198725 }}</ref><ref name="-2007">{{Cite journal  | title = Flurbiprofen: new indication.

* [[Bacterial]] [[pharyngitis]] is common among young children and adolescents. [[Group A streptococcal pharyngitis]] is the only common form of the disease for which [[antimicrobial]] therapy is definitely indicated. Therefore, when a clinician evaluates a patient with an acute sore throat, the most important clinical task is to decide whether or not the patient has “strep throat.”<ref name="pmid11172144">Bisno AL (2001) [https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&retmode=ref&cmd=prlinks&id=11172144 Acute pharyngitis.] ''N Engl J Med'' 344 (3):205-11.

Risk calculators and risk factors for Pharyngitis medical therapy

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Chetan Lokhande, M.B.B.S [2], Venkata Sivakrishna Kumar Pulivarthi M.B.B.S [3]

Overview

The majority of cases of pharyngitis are self-limited and only require symptomatic therapy. Accurate diagnosis of streptococcal pharyngitis followed by appropriate antimicrobial therapy is important for the prevention of acute rheumatic fever, for the prevention of suppurative complications (e.g, peritonsillar abscess, cervical lymphadenitis, mastoiditis, and, possibly, other invasive infections), to improve clinical symptoms and signs, for the rapid decrease in contagiousness, for the reduction in transmission of GAS to family members, classmates, and other close contacts of the patient to allow for the rapid resumption of usual activities; and for the minimization of potential adverse effects of inappropriate antimicrobial therapy.

Medical Therapy

  • As viral infections are the most common causes of pharyngitis in children, most patients do not require treatment and only need supportive care.[2]
  • Bacterial pharyngitis is common among young children and adolescents. Group A streptococcal pharyngitis is the only common form of the disease for which antimicrobial therapy is definitely indicated. Therefore, when a clinician evaluates a patient with an acute sore throat, the most important clinical task is to decide whether or not the patient has “strep throat.”[3]

Corticosteroids

Corticosteroids have been studied and recommended by a guideline[4], but results were heterogeneous in a meta-analysis[5].

The most recent trial in the meta-analysis showed[6]:

  • Insignificant benefit in the primary outcome at 24 hours. Risk difference of 4.7% (95% CI, −1.8% to 11.2%)
  • Significant benefit at the secondary outcome of 48 hours. Risk difference of 8.7% (95% CI, 1.2% to 16.2%)

Other Treatment Regimen

Supportive Therapies Systemic Therapy Antimicrobial Regimens

Topical therapy

  • Oral rinses were more effective in treating conditions affecting oral cavity and base of the tongue whereas sprays were more effective in coating the posterior pharynx and hence they were used to treat posterior pharynx conditions.[7]

Oral rinses

  • Saltwater gargles do not demonstrate any benefit in relieving throat pain. There are minimal side effects associated with these oral rinses.
  • Lidocaine, Diphenhydramine and Maalox (Aluminium hydroxide, magnesium hydroxide and simethicone) have shown to be helpful. This combination can be used to treat Coxsackie A or B infection or herpes simplex. Avoid using the lidocaine over its recommended use.[8][9]
  • Benzydamine hydrochloride rinses have shown to help reduce the pain in a few cases. However, they are used more frequently to treat radiation mucositis.[10][11]

Sprays

Lozenges

Analgesics

Glucocorticoids

Streptococcal pharyngitis[3]

  • Preferred regimen (children): Penicillin V 250 mg PO bid-tid for 10 days
  • Preferred regimen (adolescents and adults): Penicillin V 250 mg PO qid OR 500 mg PO bid for 10 days
  • Alternative regimen (1): Amoxicillin 50 mg/kg PO qd for 10 days (maximum dose 1 g/day) OR 25 mg/kg bid for 10 days (maximum dose 500 mg/day)
  • Alternative regimen (2): Benzathine Penicillin G 0.6 MU (<27 kg)/ 1.2 MU (≥27 kg) IM single dose
  • Alternative regimen (3): Cephalexin 20 mg/kg PO bid for 10 days (maximum 500 mg/dose)
  • Alternative regimen (4): Cefadroxil 30 mg/kg PO qd for 10 days (maximum dose 1 g/day)
  • Alternative regimen (5): Clindamycin 7 mg/kg PO tid for 10 days (maximum 300 mg/dose)
  • Alternative regimen (6): Clarithromycin 7.5 mg/kg PO bid for 10 days (maximum 250 mg/dose)

Other bacterial pharyngitis

Chronic Carriers of Group A Streptococci

Antimicrobial therapy is not indicated for the majority of chronic carriers. A few conditions where antibiotics are recommended are:

  1. An outbreak of rheumatic fever, acute poststreptococcal glomerulonephritis or invasive GAS infection
  2. Closed community outbreak of GAS pharyngitis
  3. Family history of acute rheumatic fever
  4. Excessive anxiety about rheumatic fever
