It is approximately 13 per cent less potent (by molarity) than racemic bupivacaine.Levobupivacaine is indicated for local anaesthesia including infiltration, nerve block, ophthalmic, epidural and intrathecal anaesthesia in adults; and infiltration analgesia in children. Adverse drug reactions (ADRs) are rare when it is administered correctly. Most ADRs relate to administration technique (resulting in systemic exposure) or pharmacological effects of anesthesia, however allergic reactions can rarely occur.

Desloratadine is used to provide symptomatic relieve of allergic symptoms.

Doxylamine Succinate is a pyridine derivate histamine H1 antagonist with pronounced sedative properties. Doxylamine succinate (Decapryn) competitively blocks the histamine H1 receptor and limits the typical allergic and anaphylactic responses, including bronchoconstriction, vasodilation, increased capillary permeability, and spasmodic contraction of the gastrointestinal smooth muscle, caused by actions of histamine on bronchial and gastrointestinal smooth muscles, and on capillaries. This drug also prevents histamine-induced pain and itching of the skin and mucous membranes.

1-beta-D-Arabinofuranosyluracil (Uracil 1-β-D-arabinofuranoside), isolated from the Caribbean sponge [Tectitethya crypta], is a methoxyadenosine derivative with anti-inflammatory activity, analgesic, and vasodilation properties.

Bromfenac sodium hydrate (Bromfenac monosodium salt sesquihydrate) is the sodium salt form of bromfenac, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and anti-inflammatory properties. Upon ophthalmic administration, bromfenac binds to and inhibits cyclooxygenase II (COX II), an enzyme that converts arachidonic acid to cyclic endoperoxides, which are prostaglandin (PG) precursors. By inhibiting PG formation, bromfenac prevents PG-induced inflammation, vasodilation, leukocytosis, disruption of the blood-aqueous humor barrier, increased vascular permeability, and elevated intraocular pressure (IOP).

Prostaglandin E1 (Alprostadil) is the naturally occurring prostaglandin E1 (PGE1) which displays a variety of pharmacologic actions. Prostaglandin E1 is a potent vasodilator agent that increases peripheral blood flow, inhibits platelet aggregation, and induces bronchodilation.
