We are able to set certain benchmarks in the medical
industry, by offering well-formulated range of Tetracaine Eye drops.
They are used in numbing the eyes by blocking the nerve impulses that are
used during the eradication of corneal foreign bodies, gonioscopy, for
short corneal and conjunctival operations. Tetracaine 0.5 % Eye drops is
non-allergic in nature and is safe in usage. It functions by interfering
with the entry of sodium ions into the nerve cells thereby reducing the
ability of sensation.
| COMPOSITION: w/v |
- Amethocaine HCl BP 0.5%
- Benzalkonium Chloride BP 0.01%
- (Not as Separate Point)
- Aqueous base: q s
|
| Mechanism of action: |
- Amthocaine hydrochloride is used as a local anesthetic which acts
by reversibly blocking the propagation and conduction of nerve
impulses along nerve axons. Amethocaine stabilizes the nerve
membrane, preventing the increase in sodium permeability necessary
for the production of an action potential.
|
| Indication: |
- Ocular anesthetic for topical instillation into the conjuctival
sac
|
| Contraindications: |
- Not to be used in patients with a known hypersensitivity to the
product. Amethocaine is hydrolyzed in the body to p-amino-benzoic
acid and should not therefore be used in patients being treated with
sulphonamides. In view of the immaturity of the enzyme system which
metabolises the ester type local anesthetics in premature babies,
amethocaine should be avoided in these patients.
|
| Adverse effects: |
- Amethocaine may give rise to dermatitis in hypersensitive
patients. On instillation an initial burning sensation may be
experienced. This may last for upto 30 seconds. Corneal disorders
such a superficial punctuate keratitis or edema may be observed
following short-term application of amethocaine eye drops for
topical anesthesia. The cornea may be damaged by prolonged
application of eye drops.
|
| Dosage & administration: |
- Adults & children - one drop or as required.
|
| Warning & precautions: |
- To avoid contamination do not touch tip of container to any
surface. Replace cap after using. The anesthetized eye should be
protected from dust and bacterial contamination. The cornea may be
damaged by prolonged application of anesthetic eye drops. Systemic
absorption may be reduced by compressing the lacrimal sac at the
medial canthus for a minute during and following the instillation of
the drops. (This blocks the passage of the drops via the
naso-lacrimal duct to the wide absorptive area of the nasal and
pharyngeal mucosa. It is especially advisable in children.)
|
| Storage: |
- Keep in cool dark place
- Keep out of reach of children
|
| Presentation: |
- Amethocaine eye drops are available in sterile plastic bottle of
5 mL.
