酒石酸溴莫尼定滴眼液的药理学综述
（1）药理作用
本品具有双重作用机制，即通过减少房水的产生及增加房水的巩膜色素膜外流而降低眼
压。
降眼压作用：眼压正常的白兔眼，用浓度由0.0001%~0.5%的酒石酸溴莫尼定局部点眼单滴试验，发生系列的降眼压作用，其中0.1%产生最佳的降眼压效果，最大下降值为5.1±0.6mmHg；眼压正常白兔眼，用浓度由0.08%~0.8%的酒石酸溴莫尼定连续6个月、每天2次局部点眼试验，浓度为0.08%，0.2%，0.5%，0.8%眼压的最大下降值分别为3.9±0.4，5.1±0.4，6.9±0.3，7.1±0.4mmHg；在猴眼，用浓度分别为0.3%，0.5%，1.0%的酒石酸溴莫尼定可分别降低眼压4.9±2.0，9.9±1.2，7.3±1.5mmHg；高眼压猴，用氯胺酮麻醉后，滴0.5%的酒石酸溴莫尼定可使平均眼压最大下降22.3±3.2mmHg（发生在点药后4小时）；猫眼，0.1%酒石酸溴莫尼定眼压最大下降值为6.9±1.1mmHg。
对瞳孔的影响：瞳孔开大肌上有α1受体，刺激此受体可使瞳孔放大，酒石酸溴莫尼定对α2受体的选择性高于α1受体的1000倍，因此对瞳孔几乎无影响。
对血管收缩性的影响：治疗浓度的酒石酸溴莫尼定对血管收缩无影响。
神经保护作用：对成年大鼠视神经的研究发现，酒石酸溴莫尼定可防止由挤压伤引起的视神经和视网膜节细胞的继发变性。挤压伤后腹膜内注射酒石酸溴莫尼定100μg/kg，可使视神经的应激性增加2.5倍，使视神经细胞的活性增加4倍。
（2）药动学及毒性
酒石酸溴莫尼定不仅分布于眼球的前节，而且也能达到后节，大部分经肝脏代谢，经肾脏排泄。
大量动物试验表明酒石酸溴莫尼定是安全的。在长达一年的眼部（浓度0.08%~0.8%，每日2次）和全身（0.1~2.5mg/kg，口服）用   药证明，酒石酸溴莫尼定对各种器官均无毒性；对生殖也无影响，无致癌和致畸形作用。
（3）临床评价
在治疗原发性开角型青光眼和高眼压患者时，0.2%酒石酸溴莫尼定有显著的降眼压作用，并有较好的眼部耐受性，对呼吸系统和心血管系统的影响也较小。降眼压作用：0.5%酒石酸溴莫尼定可有效地防止氩激光小梁成形术（ALT）引起的眼压升高，使眼压下降幅度高于赋形剂10mmHg，对术后3小时发生的眼压升高，用药组的发生率为1%~2%，而对照组为23%；0.2%和0.5%的酒石酸溴莫尼定均有显著的降眼压作用，最大的降眼压值分别为6.7±3.6和7.7±3.5mmHg，降眼压效果大致相同，对于原发性开角型青光眼和高眼压长期使用者，0.2%为最佳浓度，而对于ALT手术者多选用0.5%的酒石酸溴莫尼定；
耐受性：使用4种不同浓度的酒石酸溴莫尼定（0.08%，0.2%，0.35%，0.5%）和其赋形剂
进行观察，一眼用酒石酸溴莫尼定，另一眼用赋形剂，每日点2次，连续5天，结果表明，酒石酸溴莫尼定有明显的降眼压的作用，且局部和全身能够很好地耐受此药，仅0.5%有不适感；
安全性：在ALT手术前后使用酒石酸溴莫尼定，0.5%酒石酸溴莫尼定的基础心率与对照组相比无明显变化，手术前后收缩压和舒张压均略有下降，无临床意义；点药后的副作用有视物模糊、刺痛及烧灼感、口干、眼睑退缩、结膜苍白、疲劳等。

TIMOLOL MALEATE(马来酸噻吗洛尔)
药物相互作用：
1．与肾上腺素合用可引起瞳孔扩大。
2．不主张两种局部p受体阻断剂同时应用。
3．本品与钙通道拮抗剂合用应慎重，囚可引起房室传导阻滞，左心室衰竭及低血压。肘心功能受损的患者，应避免两种药合并使用4．正在服用儿茶酚胺耗竭药(如利血平)者，使用本品时应严密观察，因可引起低血压和明显的心动过缓。
5．本品与洋地黄类和钙通道拮抗剂合用可进一步延长房室传导时间。
6，本品与奎宁丁合用能引起心率减慢等全身p受休阻断的副作用。可能的原因是奎宁丁可抑制P450酶和CYPZD6对噻吗洛尔的代谢作用。
药理作用：

Combigan
Generic Name: brimonidine and timolol ophthalmic (bri MOE ni deen and TIM oh lol)
Brand Names: Combigan
---------------------------------------------------------------------------
What is Combigan?
Combigan contains brimonidine and timolol.
Brimonidine is an alpha-agonist that reduces the amount of fluid in the eye, which decreases pressure inside the eye.
Timolol is a beta-blocker that also reduces pressure inside the eye.
Combigan is used to treat glaucoma or ocular hypertension (high pressure inside the eye).
Combigan may also be used for other purposes not listed in this guide.
---------------------------------------------------------------------------
Important information about Combigan
Do not use Combigan if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days.
You should not use Combigan if you are allergic to brimonidine (Alphagan) or timolol (Timoptic, Cosopt), or if you have certain conditions. Be sure your doctor knows if you have asthma, or severe chronic obstructive pulmonary disease (COPD), heart disease or heart failure, slow heartbeats, or a heart condition called "AV block."
Before using Combigan, tell your doctor if you have diabetes, overactive thyroid, circulation problems, allergies, low blood pressure, myasthenia gravis, or a history of depression
Do not use Combigan while you are wearing contact lenses. This medication may contain a preservative that can be absorbed by soft contact lenses. Wait at least 15 minutes after using Combigan before putting your contact lenses in.

How should I use Combigan?
Use Combigan exactly as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended. Follow the directions on your prescription label.

Wash your hands before using the eye drops. Do not use Combigan while you are wearing contact lenses. Combigan may contain a preservative that can be absorbed by soft contact lenses. Wait at least 15 minutes after using the eye drops before putting your contact lenses in.
To apply the eye drops:
Tilt your head back slightly and pull down your lower eyelid. Hold the Combigan dropper above the eye with the dropper tip down. Look up and away from the dropper as you squeeze out a drop, then close your eye.
Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct.
If you use any other eye medications, wait about 5 minutes after using Combigan eye drops before using the other medication.
Do not allow the dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
Do not use Combigan if the liquid has changed colors or has particles in it. Call your doctor for a new prescription.
Tell your doctor right away if you have any eye injury or infection. If you have any type of surgery, including eye surgery, tell the surgeon ahead of time that you are using Combigan. You may need to stop using the medicine for a short time.
Store Combigan at room temperature away from heat and moisture. Keep the bottle tightly closed when not in use.
---------------------------------------------------------------------------
What happens if I miss a dose?
Use the medication as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.
---------------------------------------------------------------------------
What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine, or if anyone has accidentally swallowed it.

Overdose symptoms may include dizziness, headache, slow heart rate, and feeling short of breath or like you might pass out.
