It a type of a tablet that dissolve, sprays or
film that is used by placing the drug under
the tongue, and it is absorbed and dissolved
into the blood stream through the mucous
membrane. it is considered to be absorbed
very fast into the circulation, as it doesn’t
pass through the digestive system and the
area under the tongue is rich with tiny blood
capillaries. Sublingual is used in such cases
as :
- Patient that cannot swallow drugs
- Drugs that should be absorbed quickly into
the circulation
- Drugs that the digestion would decrease
there effect. (Lowey, H., 1999)
- Buprenorphine HCL: treat the opioid
dependence.
- Isosorbide dinitrate: treat attack of angina.
- Hyoscyamine sulphate: antispasmodic or
anticholinergic to treat stomach problem like
cramps, bowel control problem and bladder.
- Ergotamine tartrate: treat migraine.
- Asenapine: treat antipsychotic like
schizophrenia and acute mania.
- Fentanyl citrate: analgesic opioid agonist.
- Orchard, timothy and sweet vernal:
immunotherapy to treat symptoms of grass
pollen allergic rhinitis
- Zolipidem tartrate: sedative and hypnotic.
Used to treat sleep problem.
- Nitroglycerin: vasodilator.
- Ondansetron: block action of chemical in the
body trigger like nausea and vomiting that
may cause by medicine to treat cancer
- Polyethylene glycol 3350: polymer of film
coat-tablet. (Pather, 2001)

2. Advantages
• A relatively rapid onset of action can be achieved
compared to the oral route, and the formulation
can be removed if therapy is required to be
discontinued.
• Liver is bypassed and also drug is protected from
degradation due to pH and digestive enzymes of
the middle gastrointestinal tract
• Improved patient compliance due to the
elimination of associated pain with injections;
administration of drugs in unconscious or
incapacitated patients; convenience of
administration as compared to injections or oral
medications.
• Low dosage gives high efficacy as hepatic first
pass metabolism is avoided & reduces side effects.
• The large contact surface of the oral cavity
contributes to rapid and extensive drug absorption.
• Due to rapidity in action these sublingual dosage
forms are widely used in emergency conditions e.g.
asthma. (Fusari,2005)
• Rapid absorption and higher blood levels due to
high vascularization of the region and therefore
particularly useful for administration of anti-angina
drugs.
• They also present the advantage of providing fast
dissolution or disintegration in the oral cavity,
without the need for water or chewing.
Disadvantages
• Since sublingual administration of
drugs interferes with eating, drinking,
and talking, this route is
generally considered
unsuitable for prolonged
administration. (Pawar et al, 2018)
• Although this site is not well suited to
sustained‐delivery systems.
• Sublingual medication
cannotbe used when
a patient is Un-cooperative or unconscious.
• The patient should not smoke while taking
sublingual medication, because smoking causes
vasoconstriction of the blood vessels. This will
decrease the absorption of the medication.

may interferes with food and drinking, not used with
unconscious patient. There are many API of the
sublingual tablets such as Buprenorphine HCL,
Isosorbide dinitrate, and Hyoscyamine sulphate, etc .
there are many international and national drugs
used as sublingual such as saphris, abstral, isodril
