Vs 204 unit 16 miscelaneous drugs
Unit Overview
Pharmacology Miscellaneous covers a range of veterinary medications suitable for different conditions in animals, with a focus on urinary issues, topical ophthalmic drugs, otic treatments, and skin care.
Page 2: Urinary Incontinence - Phenylpropanolamine
Propalin® Syrup: This medication is a sympathomimetic agent administered orally every 8-12 hours. Its primary function is to stimulate the urethral sphincter muscle, making it especially beneficial for spayed female dogs. However, it should be avoided in animals that are on cardiac medications such as beta blockers due to potential contraindications.
Page 3: Side Effects of Propalin
Behavioral Effects: Possible side effects include aggression and restlessness.
Cardiovascular Effects: Tachycardia may occur in some cases.
Gastrointestinal Effects: Vomiting and diarrhea are potential adverse reactions.
Neurological Effects: Seizures have been noted as a serious side effect.
Page 4: Urinary Retention - Prazosin
Prazosin is utilized primarily to treat hypertension by relaxing blood vessels. It is also employed for post-urethral blockage in cats to help decrease urethral sphincter tone, thereby facilitating urine voiding.
Page 5: Zylkene®
Active Ingredient: Alpha-S1 Tryptic Casein (alpha-casozepine), derived from milk protein, provides calming properties to animals.
Page 6: Mirtazapine
Formulation: Mirtazapine is available in oral tablets (15 mg) and transdermal gel formulations used specifically for cats.
Purpose: It acts as an appetite stimulant for cats suffering from weight loss or poor appetite. Keep out of reach of children.
Page 7: Solensia® Injectable
Type: Monoclonal antibody targeting nerve growth factor (NGF).
Use: This treatment is indicated for osteoarthritis in cats, administered through a monthly SQ injection.
Side Effects: No known side effects reported.
Page 8: Librela® Injectable
Type: Similar to Solensia, this monoclonal antibody targets NGF.
Use: It is used for treating osteoarthritis in dogs, also through monthly SQ injections, with no known side effects documented.
Page 9: Overview of Ophthalmic Drugs
Introduction to various ophthalmic treatments, focusing on the types and applications.
Page 10: Ointment vs Drops
Drops: Used as solutions and suspensions, required every 2-4 hours.
Ointments: Applied every 4-6 hours; can cause prolonged blurred vision.
Page 11: Mydriatics
Function: These drugs dilate pupils and are crucial for eye examinations and treating uveitis, which can prevent synechia.
Page 12: Mydriatics - Examples
Atropine: Caution is advised as it can increase intraocular pressure (IOP) and is contraindicated in glaucoma patients. Side effects include a bitter taste and hypersalivation in cats; prolonged pupil dilation may occur.
Tropicamide: Faster onset and shorter duration than atropine. It may cause hypersalivation without affecting IOP.
Page 13: Miotics
Mechanism: Help reduce intraocular pressure by constricting pupils and are used in glaucoma treatment.
Example: Pilocarpine drops (Isopto® Carpine) function by increasing aqueous humor outflow and relieving pressure.
Page 14: Timolol (Timoptic®)
Function: Primarily reduces IOP by decreasing aqueous humor production, often combined with dorzolamide for enhanced effect.
Page 15: Topical Ophthalmic Anesthetics
Purpose: Used for eye exams and surgical procedures, with examples including Proparacaine (Alcaine®), which requires refrigeration.
Page 16: Analgesia/Anti-inflammatory in Ophthalmology
Function: Treats ocular pain associated with ulcers and inflammatory conditions using ointments or drops such as Diclofenac (Voltaren®).
Page 17-18: Dexamethasone
Dexamethasone is available both as a suspension and ointment for topical application in treating various eye conditions, and it may be used alone or in combination with other agents.
Page 19: Antibacterial Ophthalmic Drugs
Formulation: Available as ointments or drops, these may sometimes be combined with corticosteroids. Examples include Maxitrol® and Tobrex®.
Page 20: Immunosuppressants
Example: Cyclosporine (Optimmune) is used for treatment of KCS (keratoconjunctivitis sicca) and has anti-inflammatory properties.
Page 21: Lubricants/Artificial Tears
Indicated for use during anesthesia or in KCS/pannus situations. Examples include Optixcare® Eye Lube.
Page 22-23: Otic Drugs
Otitis Externa: The most common causes include Malassezia yeast and various bacteria. Treatment is generally effective against all three causes (yeast, bacteria, mixed infections).
Page 24: Common Otic Treatments
Various otic solutions discussed, addressing antifungal, antibacterial, and anti-inflammatory components, including specific products and usage guidelines.
Page 25-26: Special Considerations in Otic Treatments
Detailed product considerations for veterinary ear ointments, ensuring compatibility and safety regarding species usage.
Page 27: Claro®
This product provides a single-application treatment lasting 30 days, applied in clinic settings with caution noted about tympanic membrane integrity.
Page 28: Prevention Strategies for Otitis Externa
Continuing prevention includes the usage of cleaning and drying agents on a regular basis to maintain ear health.
Page 29: Overview of Topical Skin Products
Introduction to the different categories of topical products for skin care in animals.
Page 30: Types of Shampoos
1. Cleansing: Focused on removing dirt and oils; only animal-specific shampoos should be used.
2. Antiparasitic: Selection based on conditions; usually contain pyrethrins.
3. Medicated: Treats specific conditions with recommended application times for efficacy.
Page 34: Additional Treatments
Details on topical treatments such as Magnesium sulfate for drawing out fluids, and Chlorhexidine as an antiseptic.
